Hello all, I have a Samsung Galaxy S3 GT-I9300 with Stock 4.1.2 unrooted and baseband version I9300DXEMB1. The problem I have is when I try to connect with my home WiFi from my room, it says Authentication Error Occurred. I have to be directly infront of the router then it'll connect and allow me to load webpages.
If I stand in front of the router and connect, It will get connected without any problems but as soon as I return back to my room or any other place that is more than 3 feet away from the router, it wouldnt load any webpages or anything that requires an Internet connection. Then when I toggle WiFi off and on again, the authentication error occurred problem will be back. It's like my phone can only connect and load webpages when it is 1cm in front of the router. Does anyone here have any suggestion on how to help me? I'm pretty sure that it is not my router's problem because my computer and Galaxy S4 in my room can connect just fine and load webpages just fine. I've tried searching the Internet for solutions but have not found anyone with the exact same problem with range/signal strength hence I started this thread.

Rooted the phone and installed Siyah kernel. Problem still persist. Any other possible fixes? Continued my search and found this thread http://forum.xda-developers.com/galaxy-s3/help/galaxy-s3-wont-connect-to-wifi-t1779535 Same problem with what OP is experiencing. (Post #10)
I once had the same problem and fixed it by deleting the .cid.info file in /data.

I did the exact same thing and still no improvement. Could it be a hardware issue?. I've tried rebooting router, forgetting network, turning off Wifi power safe mode in *#0011# menu but to no avail

Suggest wipe phone install stock rom and test .
If it connects to other routers/ wifi its your router a problem .
I had these kinds of problems with two stock ROMs, do not remember the exact versions, but when I upgraded the problems were gone. That was while using the exact same Yank kernel, so it doesn't seem kernel related. It is a very annoying bug though! But upgrading ROM will fix it, I know for a fact that GNA5 doesn't have this bug.
Have you tried using wifi on other places on the same phone?

Since I saw that lots of people have the same problem. I like many other, I have done everything said here, and all over the web.
Here is what I did to fix my problem...
1 - Check if you have any special char on the wi-fi SSID like "!,@,',ã,á,~,ç,ã" etc...
and Remove it.
2 - On your router check if you have ip adress ranged configured like: 192.168.1.100 to 192.168.1.150, and change it to the wide range: 192.168.1.1 to 192.168.1.254
This two steps solved my problem after I have tried everything stated here and over the web
I just registered to share this and hope to help someone.

The thread also highlighted using static IP to solve the issue.
Plus, you can try to change the router transmission channel to a lower number and see if it works.

Thanks for the reply, hard resetted the phone back to everything stock and tried 2 different stock firmwares but still no luck. I also went to format /data and cache in stock recovery just to make sure but still same problem.

I've tried other Unsecured networks around my area. Same problem. Very sure it is not my router problem as my other phone and computer can connect just fine and even getting at least 20mbps speed. This S3 can only connect when I'm physically beside the router.

Thanks for suggestions, I've also tried Static IP and checked my router settings and that it doesnt have those punctuations in the SSID and also the start and end IP is pretty wide from 192.168.1.1 to 192.168.1.253 (I don't think that 1 difference from .254 could make a difference could it?) I'm really starting to believe that It's a hardware issue. I'm probably going to contact a person to diagnose the phone tomorrow. Maybe it could be a malfunction of the WiFi chips in the phone.

If there is authentication error then that means that the phone can detect the wireless network so the hardware seems ok. Did you try to change the router channel? And even try changing the transmission from a/b/g/n to "G only" or "N only".

That's exactly what I thought too. Why can't it connect if it can detect the network? And I've since tried changing channels only for it to return to the same result, authentication error. And my router settings do not have an option to change the radio type. I can't remember exactly where but it might be Android forums or something (read too many different forums over the past few days) and this guy said that maybe it was some power management failure thing. I'm not an expert with hardware and can't provide any explanation or theory. Maybe there's some other component that manages the power to use that'll enable the phone to receive data from the router and that thing malfunctions while the main wifi chip still works that explains why I can still detect wifi networks?
[Edit]I'm also thinking that maybe because this Imaginary power management component inside the phone is malfunctioning/not receiving enough power, that's why when im in a room different from where the router is, i cannot connect because the phone isn't receiving enough power to validate the data from the radio waves and also because when Im standing beside the router then can load webpages just fine because the Signal strength is high and probably the radio waves from the router is emitting high energy so the power management component doesn't require as much energy to receive data compared to when Im in my room. Something like the router shouting and your phone needs a certain amount of energy to hear the voice from the room otherwise you cant but if you're standing beside it you can hear it no matter what. (This is just my theory and what Im thinking the problem is. It is not an explanation but just my opinion. This information could be totally wrong for all I know.)

@Hazerm, can you try WPS setup if your router supports it?
On your phone: Settings > WiFi > Menu > WPS
Rebooting the router is also recommended. Maybe you can also try changing the security on the router to WPA/WPA2

Yep, WPS is supported and enabled on my router. Use it cause I was too lazy to retype my password everytime i flashed a firmware on the phone haha. And same thing. when I try to connect using WPS, the phone (in my room or any location 10cm or more away from router) doesnt react even after pushing the button on the router. But if I were to stand beside the router, WPS works without any problems.

No improvement, unfortunately The progress bar just crawls to the end and the phone just says WPS failed. This was approximately 1 meter away from the router, I have to be less than 1 metre from the router to get a connection. Btw, router was rebooted several times and Security has always been WPA/WPA2-PSK, not very interested in changing the security to other types like WEP. Just not very trustable

I can understand that this is very frustrating for you. Believe me, I've had issues with phones and wifi
Ok, so I found 2 short threads that you could read:
Link 1
Link 2
Summary:
- try the steps in Link 1
- Change phone frequency from 2.4ghz to 5GHz (had this option in Omega ROM 4.3-based)
- 2 users report that the issue is fixed in CM9 (or even other CM roms)
- Might be a mainboard issue after all.
PS: Surprisingly, some of the people reporting the issue have used Omega rom in the past and faced the issues since then. (I didn't have any issues though so I cant blame the rom)

Don't worry about Knox, it is not present in 4.3, so you can just flash GNA5 and be done with it! I do recommend Nova or Apex launcher though, way smoother!
For all the other people here, this is a known bug with certain routers that are not 100% compliant with the WiFi standard and therefor do not confirm the handshake. I have had these problems with certain ROMs as well (cannot exactly remember which ones) and after flashing another ROM (at the moment I am on GNA5) Samsung fixed it, while it is not even their issue, the issue/bug lies within the routers that pose problems.

Really? Because with the Galaxy S4, late 4.2.2 firmwares and all 4.3 and above firmwares had new Knox bootloaders which means no turning back to old 4.2.2 ROMs and also the Knox 0x1 flag which to my knowledge is not resettable at the time of this writing.

Router information: Linksys Wireless-N WRT120N
I have done everything that i could think of to get this working. i have done several google searches and they all say to do specific things.
For example:
-Reset router
-Enable B/G only or G only set at channel 11
-turn off router firewall settings
-and a bunch of other random sh*t
i have done all of the above then some and i still cant get it to connect. all i get is *scanning* then *disconnected* thats the only two things it says. except right after i reset the router. every time i reset the router i get * obtaining IP yadadada* then goes to *disconnected* then back to the "scanning, disconnected" loop.
there have been some people that have said flashing a custom firmware on the router would fix the issue with mobile connectivity on Wireless-N routers.
please someone be helpful with this and please dont tell me i need to reset my router. i have asked this same question on several forums and the only replies i get are "if you reset the router and turn off security it WILL work fine" thats bull****. im not an idiot. thats the first step any computer literate person would take before asking questions.
**Update: same as from General thread. i had to repost because it was closed for some reason there. also here are the answers to the other two guys to responded.
"not standing close enough" -i have been standing next to it. i have yet to test it more than 10 feet away lol so it cant be there
"flash another rom or reflash current rom" -it has nothing to do with my rom, kernal, or radio. this issue is also happening on my girlfriends xperia running Wolfxperia and mine is the blackeditionHDv2. its also an issue with her sisters xperia. hers is still stock 2.2(i think). their stepdad has an iphone and it wont connect with that either. from what ive gathered... its a mobile issue. i know all these phones say (b or g only) but even setting the router to broadcast in b/g it still wont connect. it notices the routers name with full strength on all devices. also i might add that their laptop is an older laptop. does not support N but still can connect to the router and have internet.
Same here. Xperia mini x10 pro. When on it says connecting even thought I nothing appear visible.

any idea on how i can solve this?
I'm guessing this is an ip issue. The mobile devices are not able to get one. This usually happens to me on a public network and I even get a " limited or no connectivity".
The work around I do is to assign a static ip on my phone. Its very simple to do and if you need help doing it, let me know.
There's no clear explanation I can tell you, but it seems some mobile devices have a hard time pulling ip's from different types of routers. Hope this helps.

Will ask my gf to give it a try. It happened so abruptly, it was working fine when she was at col then when she came back it won't detect any wifi, whether it's her house or mine, and now that she is back at her col she still can't connect.
I know how you feel.
I have had this issue ever since I first upgraded to Stock 2.3.3 last July. On 1.6 and 2.1 (both stock also) I never had issues.
Basically, in my case, resetting the router DOES solve the problem, but only for a limited time. This limited time is random, as sometimes it will work for a few days, and then sometimes it will cut out a few hours again after I have reset my router. I am also using the static IP method (and an app called WiFi Stat which I initially thought had solved the problem, but it hasn't) I'm not sure what triggers the WiFi connection to be lost, but there must be a trigger. Like I said, I never had this issue in my previous old Android versions.
I had hoped (somewhat naively) that moving to a custom ROM would solve the issue, but after installing Wolf's latest ROM, I still have this issue.
Have you tried anything based on 2.3.4 or above, to see if this is an Android 2.3.3 issue? Are there any good ROMs people could recommend that are based on higher versions than 2.3.3?
WEP/WPA key issue?
If its not the kernel/ROM/version of the phone, it could have something to do with the way the security is set up for your router. I had the most frustrating time logging into my university's wireless (think it was encrypted with 802.1x EAP) which required username and password. Though most home-owned router are equipped with WPA/WPA2 PSK or WEP, you can try the steps below:
1. Go to Settings ->Wi-Fi Settings -> Add Wi-Fi network
2. Type in the network SSID (yeah this is the manual part)
3. Open the "Security" drop-down box and set the following:
Security: 802.1x EAP
EAP method: PEAP (default)
Phase 2 auth.: MSCHAPV2
CA cert.: leave unchanged
User cert.: leave unchanged
4. Type in username (if any) and password.
Once again, this would work 99% for 802.1x...not sure about WPA/WEP. Good luck!
Try Channel 6 in router option and hope it works.
Solve
setting a static ip doesnt seem to work.. any idea? i wish not to re-flash as i dun think that would be a permanent solution.
again i dun think it has anything to do with my router as other gadgets are able to connect with it and i didnt fiddle with the security.
It is unable to detect any router as i have tried it different hotspots.
Hope to get some help.
------------------------------------
I wipe clear the settings and it worked again.. hope the problem doesn't persist again.
My model is YP-G70 , firmware 2.3.5 on original updated stock rom.
My wifi working very well when I used with my others device (HTC Desire, Nook Color and PC) but with my awesome Samsung Player...
Every some minute the player drop the wifi line and after 1/2 second reconnect.
And i loose my download
Incredible.
I turn off Juicedefender, I 've setup the wifi property "Wifi sleep policy" with NEVER, I turn on KeepWifi Service (app) but.. NOTHING.
Do you have some advice?

I had the same issue when I bought my US model. But I only had the issue with my home wifi and not anywhere else. Can you connect at another location and see if you have the same issue? I ended up just replacing my old Belkin router and haven't had an issue since.

Try installing KeepWifi, see if that works. Otherwise it could be your router configuration, like the kind of encryption you use for your wifi password. Try to reset your router but don't use any password for a little while, if that works, use another encryption method.

Solution

I read this solution in an old XDA item of this forum. Thanks!!!
Hi
I have the same problem with my G70. For to have the max signal in the device i need to go beside my router. I have try with other router but the problem is the same.
maybe is only the display animation in the screen? I say that because i check the quality of my signal at it tell me GOOD.
im also having this problem on my I9003.
the wifi sleep policy has a bug.
some say that your Security/password should be WPA or WPA 2, they said this happens on WPA-secured routers, i haven't confirmed it though.
the only temporary solution for this is to disconnect or turn off the wifi in your phone settings and turning it on again, then you can connect again.
Due to the ROM,i think.Because wifi on 2.2.1(mine is YP-G1) functions great
Dose G70 have a ROM of 2.2.1?If so,you can try it yourself if you like
well i found a fix for this bug, just download the latest version of WiFi fixer from the Play Store.
that's the easiest way to fix this wifi sleep bug.
Hello, I am having the same problem, but I suspect my situation is worse. I've even tried the wifi fixer app, but my 5.0 drops wifi and breaks large downloads and games that require constant connection.
Do I have a defective unit? Any advice and help would be much appreciated.
Solution! (for me at least) go into your router settings on ur PC and change the lease time to either Forever or 30 minutes ( I can't remember which one). It worked for me... good luck

I had this wifi problem with 2.3.5 it was really annoying . Even if i was a meter from the router the signal sometimes dropped to 1 line. Samsung fixed this problem with the 2.3.6 update, and now the signal is ok.

Not the best solution, but....
I have the same problem that happens with my SGP 5, my friend's IPAD, and the Actiontec Router that Verizon supplies with their FIOS service.
I've tried every other remedy that I can find with no success.
The only solution that works for me is to assign a static IP address to the devices. It results in a very solid and stable connection in both cases.
Hope this helps someone else !!
Thank you all for the advice, but nothing seems to work, and I have no idea how to force it to upgrade the os from 2.3.5.

Download from samfirmware (or anywhere else) the XXKPL firmware.If you are 5.0 international, simply flash it with Odin. US users must make a new tar with just the "factoryfs.rfs" in it and flash it with Odin. That will upgrade you to 2.3.6. However, if you do that, I strongly recommend installing one of the custom kernels, so it won't be impossible to root.

sup everybody.
firstly, i am a wireless expert (11+ years experience) so im not a nuubie to Wireless networks.
but i am new to Android and have just recently gotten an S3, so im hoping some body can help me.
i have an 802.11n wireless hop that connects my upstairs network to my downstairs network (internet router is downstairs)
upstairs i have an 802.11b/g access point for the older devices to connect to, this access point is connected to my 802.11n bridge
my laptop connects to the 802.11b/g network fine, and has internet connectivity (no issues)
when i first got the S3 last night, it was connecting fine as well, but since this morning, no matter what i do, the S3 connects to the access point, gets DHCP, i can ping the IP address, but it doesnt have net access, but if i connect to the 802.11n network it gets net access.
so for the life of me i cant figure out why.
so in a nutshell net access works from the laptop, but not the S3, same access point, and yes ive checked the WPA2 passkey, and the device is getting DHCP.
any suggestions.
like how to reset the IP address on the S3

Sounds like the default gateway route is not correctly received or activated. Do you have any computer/laptop with a promiscuous-capable Wifi card around that you might use with Wireshark? It should tell what exactly goes wrong.
Since you claim to be a Wifi expert I guess you won't need much help interpreting the result.

Try shutting off ur router.... Wait for a min or so then turn it bak on nd see what happens. I have an intellinet router which when the current goes off nd then on im able to connect to everythng except all google services (gmail, search, reader, syn, etc.) until i do the above. All my other devices connect fine in the meantime! Must be smthng with android....
- check the ip address.
- from device, ping its default gateway
- from device, ping external ip address that is known to response to ping
if all those works but you can't ping www.yahoo.com, it is resolver issue.
if all those including pinging yahoo works, and you still have no access, then the apps has issue or there is firewall.

I change the rooter, resetthe phone (factory Reset) but the thinks not change.
I comeback to my carrierand Ancel take my old phone and give me a new S3 (1 day old).
For 2 days, it go well, butin the final of the second day, No wireless or 3g connect, the same again.
It´s a |Firmware problem, ahardware damage, what suppose I have to do ???
My computer is normal, myold N97 is fine, It has 3G signal and navigate on Wifi and 2G/3G, but my galaxyS3 no …
I ´m very confused with this situation ... Twophones in a 3 days …

This technique works for me but only like a temporary solution. Restarting the home router also works for me but again is temporary. This issue I think is with most galaxy s3 devices. I own a galaxy tab 10.1 and it's there in it as well. huge pain to check each time, critical notifications are always missed. Have switched to bluetooth internet sharing from my laptop to avoid disruptions as I just can't trust the wireless.

Just joined to give u a suggestion
TRY
call *#0011# (Takes phone into service menu)
press menu key and select wifi
Disable wifi powersaving mode
You may need to repeat this upon phone restarts but it may well sort out your problem

not working for me
None of both have commented on my suggestion to use Wireshark on another computer to see what's actually going on.
It's hard to guess the reason since by crystall ball is broken and it's nearly impossible to get magical artifacts in pristine conditions on ebay...
No Way.
But after reset the configurations, today in 3G mode al is fine.
In wifi it shows Conected in calennetwork, after this it show internet not avaliable via selected wlan ap. It can´t navigate.
In my router page , the received packets always change, for more data and the sent packets never change.
In the avanced configuration what is the Network prefix lenght ? In my XT860 and N97 i always select the channel of the router, but in the galaxy a don´t have this option.
But the strange, is that in the 2 galaxy s3 in the first day work im my router, and then after some hours it´s crash and not navigate...
Very bad Samsung.
I´m thincking in change my S3 for a S2 or Lumia.
I´m disapointed for it, because if i change the Firmware version i lost the warranty and i have bad feeling about this isues... Is a hardware fault or a software bug ???

You only lose warranty if you bring it to a store without original Rom. Just use the normal procedure (TriangleAway, Odin, Factoryreset) to get it back to stock and you're good to go. If your device has issues preventing it from booting (so you cannot re-flash original) they can't check the binary counter either :angel:
THancks for the help.
I will going to look for triangleway & Odin in the forum.
With my Motorola XT860 i made a lot of stuff: CWM, Custom Roms... but i dont´t know nothing about the S3.
Just some days reading here in XDA and a will going to know all that kind os Staff.
Sorry for the BAd English...
I'm having this issue. I think it has to be a firmware issue as I don't think I get it if I use CyanogenMod9 or 10 (but I could be wrong)
It really is very annoying and somewhat disappointing.
Hello Again!
I tested my S3 in others routers, and all the router that working without sharedkey (open network) my S3 can conect and acess the internet.
Test your phone with one and post for us here.
OBS: In my TP link TL-WR642G it can´t conect (with and without Shared key) but in the first day yes, i don´t understand it.
I will going to 3 school who has open Internet for all the childrens and this 3 schools my s3 conect and navigate in the Internet.
Thancks for the support, if anybody change the firmware and the phone come normal again, please comeback here and post for us.
I have this problem too.. since omega. Strange...'

Anyone with this issue, please try the following:
- Take a Nandroid backup of your phone (on the internal SDcard, restoring from external seems to be broken)
- Flash CM9
- Try Wifi
If it works, please report. if it doesn't, restore the Nandroid backup and report =)
Since CM9 is not based on Samsung-software, that should answer the question about it being an issue in the newer Rom once and for all.
Hi
I have a very weird problem with Galaxy S3.
The problem is that suddenly out of the blue, the phone no longer connected to my home wifi, which it had no problems connecting to it.
the signal is extremely weak, and only connects to it when you sit next to the router.
When you forget the connection, the bars go up and connection looks very strong. as soon as you start connecting to it, it drops to the way it was, and not getting connected.
All other stuff I have (laptop and other phones) work perfectly, so not a router thing
I have rooted and updated to the latest ROM, but still same problem.
Any help would be appreciated.
is this happening with all wifi networks or just ur home network. If only on home network then try turning off your router and then restart it after some time to see if thats causing the problem.
also have u installed any updates/roms recently?

Well, I have not tried any other wifi, but I have another phone and laptop that work perfectly with the same router.
I also restarted the router, but nothing's happened.
I installed another ROM, but this time it keeps asking for password as it says it is incorrect. but as soon as I stand next to the Router, it hooks up to it with same supposedly incorrect password.
Regards

Had similar problem and I think a few people experienced this where suddenly the phone stops playing nicely with WPA2 security, so that's worth looking into

Try a Google, there were a few threads concerning it a while back, with several solutions I seem to remember
Try running router for a few days with no security see what happens .

Nothing worked!!!
Dear all,
I have tried every solution there is, tried so many routers , work, hotels, cafes ..nothing same problem keeps coming up - authentication error occurred.
when you get close enough to router it works automatically.
I have since replaced firmware many times, have replaced the antenna, but nothing ...same problem.
Any help please, I am out of ideas!!!
The only idea for me is dump it and buy an iphone!

I am facing the exact same problem with my S3.
I have all security/no security. Is there any solution?????
i can also try to repair my phone, provided someone can explain what to repair.
Looking for a response.
Same problem
Hi,
I have the exact problem.
Wifi works when phone close to router (2-3 metres). When away it still shows connected but wont have internet access.
If I try to connect little away from router with full wifi signal, it says "Saved Secured" or Authentication error.
Tried flashing different stock roms but still same problem. Tried resetting router. Tried changing router channel and disabling security. But still same.
Anyone fixed this issue?

Have you both tried a complete clean install? And by that I mean wiping /system /data /preload cache and delvik.
Yes, i have even tried other roms too..
Yes.

Hi, Thanks for the response.
Yes I did everything through recovery. I havent rooted my device. So I cleared cache and did factory reset through recovery.
After a full wipe, and flashing the 11-10 nightly, I am still having issues with wifi connections. I've had these issues for roughly 1-2 months, and it is becoming a pretty big hassle since I am eating up a lot of data without usable wifi.
Since there is a horrible rule that requires me to have 10 posts before I can post in the actual projects thread, I guess I will have to start here and hope someone sees this. If you need logcat/anything else, let me know.
I've tried turning off 'Scanning always available' and I've set the frequency to 2.4 only in the settings, no differences so far.
are you trying to connect to a wep connection or a wpa/wpa2? if so either way youo must log into admin mode on router via web browser and enter mac address of device which allows device to use router dont ask why possible security feature

No, I don't. It failing to hold a connection on any type of network. Open/WEP/WPA-2/whatever.
enter admin mode of router and add your mac address on phone in about phone and then reboot phone and see what happens it should connect right on with wep or wpa/wpa2

It has nothing to do with MAC addresses being allowed/disallowed.
ok fella what kernel are you running stock?also are you s-on or s-off if your s-off then hopefully your aware of needing to flash boot.img via fastboot and modules via recovery.
other then im short on a answer and i would provide a logcat to palmer or zarboz as they are very well master in my opinon in kernel dev and can easily help you if your nice to them.
and the mac address issue is one of the most common problems with wifi not connecting ( which for the most part is for wep only but for me it was for wep and wpa/wpa2 so those are the three main issues unless you have modem issues on your device when can happen but not likely

crpalmer's 4.9.0 with the 11-11 nightly. This wifi problem has persisted through a few different versions and full wipes. I've tried with both the 11-11 kernel, and crpalmer's. Both show no differences.

Does this occur with all roms or just with CM roms? What happens when you are at a public wifi spot? Need to figure out rom Issue phone issue or local wifi issue.

I haven't jumped to any other ROMs, but it has kept up through multiple full wipes (format everything) and re-installs of CM for a solid month now. The result is the same, whether the access point is one on or off campus, at my friends house, open security or WPA2. It will connect briefly, drop, and sometimes it will show that wifi was turned off and turned back on. Other times, I might actually hold a connection for an hour or so, but those are more rare than finding a unicorn.

Try WPA 2 with AES encryption, if that doesn't work
Back up CM and try Viper. wIFI can be a funny beast to tame

I've tried setting up my own access points and going through all the different scenarios, and I got nothing. I'm just confused as to how it is persisting through all of these perfectly clean flashes, even when other users say everything is working fine. I am probably just going to throw a hail mary and try to flash CM11 tonight.

Did you delete that file? If you want to post a logcat and a dmesg from when the wifi is disconnecting / reconnecting, I can take a look and see if there is anything useful I can tell you about it.

You don't say if you had issues prior to flashing CM... Is this something that has always been including stock?
Mine will not connect to one router I have on the guest account, that is a router issue as it will connect to my other router on a guest account. The routers are in different buildings, are different brands and one is new. Also try to connect on the 5 G band instead of the 2.4 G band

Prior to CM it was fine. Actually I believe I remember it being fine long ago on CM, though there's no way I could accurately tell you when about it was. This happens on every router I've gone tried. It's more like the actual wifi radio is turning off/on when it disconnects (which you can see it do in the settings if you watch). 5/2.4Ghz seem to be about the same. I've left it on 2.4GHz for a while now since that seems to make it a little more stable, but I'd take that with a grain of salt.

Do a back up and try Viper to see if that cures it. There have been others that have had issues with wi fi, it may be your unit won't tolerate something in the rom. They all have their own quirks.
