Wifi Problem on sams i9300 CM11 - Android Q&A, Help & Troubleshooting

Hi guys! Having a problem on all of the CM11 Roms on my 9300. The reason is that it cannot connect to networks which demand login through the login page (for home wifi spot is ok, any other open nets OK). It just seys: "the page cannot be loaded or doesnt exists". And in addition to this I found that this is dns problem or server refuses my phone. Sammy based roms I had before didnt had such problem. I really like CM11, and dont wanna live it because of that. But I really spend much time in mall (work reasons), it's crutual to me to have free unlim connection.
Thanks in advance for any help

Is it really related to CM11? U can try to change Kernel or wifi fix issue...Also try DNS change..

[Q]Android 2.3.x WIFI issue

Hello everyone
okay, i've been with a really anoying problem since the 2.3.x updates on android (Samsung Galaxy Gio in my case). The problem is that everytime I try to connect to the network, I stay some seconds with good connection and suddently the router just rebots himself. Tryed already changing some router settings (by the way my router is an Zyxel P-660W-Tx v3), setting the phone to factory, deleting apps and I always get the same result. I tryed to contact the Zyxel company but with no sucess until now. I know there's gotta be another fix than just have to buy a new router so it would be great if someone could help me out. Because this thing is freaking me out already.
Cumpliments,
Deviantor.

[SOLUTION] Samsung Galaxy S wifi 5.0 and big problem with wifi

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?
Help...
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.

Thanks for the advice...
I will try, but tomorrow I 'll be in another "wifi area" so with another router...
Solution
I've changed the "Client Lease Time" in my dhcp server (ddrwrt) from 0 to 99999 minutes.
It's working end I don't know why
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.
I don't know what to do now short of sending it to Samsung for service.

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.

[Q] i9100 Wifi Problem

Hi guys, I seem to have a problem that hasn't been easy to diagnose.
My wifi scans for networks, let's me input the WPA/WEP password and then nothing happens. When I press on "Connect" it isn't doing anything. The weird thing is that to some networks (my laptop hotspot) it connects correctly but doesn't seem to download or upload any data, but nothing happens on other networks.
I've searched around a lot and some people say that it is hardware issues, but for these guys, available networks don't even show up. So I have faith that my problem will be software related.
This first occured on Hydrog3n ROM with Fluxi Kernel, then I flashed the rom with netchip kernel, still nothing, now I'm on stock ROM and still no luck.
Any ideas??
Thanks in advance for your help.
Hi, try in router set to WPA PSK (personal) or better WPA2. maybe it will solved.
Maybe you should try to wipe phone completely data/dalvick/cashe/format sd card... Then install some fresh rom and see it then...
Thanks for your help guys!!
After fighting with this for several hours I found out the problem. My router is old and the signal it transmits is b/g. So I set it up to only g and my phone in only 2,4Ghz...
This fixed the problem!
Thanks again!

[q] wifi issues on stock based roms (feralab v 20)

i have since tired of not being able to use the major redeeming feature of this phone , which is the quality camera, so i decided to use a stock based ROM, hence FERALAB 20.
I really am not sure this a a fault of the ROM, given that i have noticed it on another previous ROM, but the thing is i cannot detect the WIFI signal from my WIMAX router using this ROM.
wifi works fine, and it does detect my neighbours WIFI networks, but i cannot seem to fathom why it does not detect mine.
like i said, i did notice this on another rom iv tried in the past, but when i changed to FXP 7.2 it worked just fine and detects my wifi network.
I would like to use a stock based ROM so im wondering if their is something i can do to help the situation.
precisely why does this ROM not see thuis particular WIFI signal, but does see others when the same phone running FXP does?
pls note that other devices, phones, laptops do connect to this router without any problem.
and i have noticed also that when i go into wifi settings on my phone, for hotspot settings it has just the options for WPA and Open modes, and no WEP option!
does that mean that the ROM cannot handle WEP connections? FXP works just fine
WEP hotspot is not available because it is a weak security. iPhone hotspots are WEP. android is always a step ahead of iPhone. So, android uses WPA hotspot. even a noob like me can crack a WEP password in 6 hours max if u wanna learn more, google for a software called aircrack. WPA is very very hard to hack. So, basically be happy that android is unhackable and iPhone is hackable.
---------------
if u are using WEP, i recommend changing to WPA or u will never know if your neighbour is stealing ur wifi. this should solve ur prob. and android cannot create WEP hotspot, but can join. i have no idea y u cant join WEP

No Internet after CM9 flash

I have just flashed the following rom http://forum.xda-developers.com/showthread.php?t=1692201. This is a WIFI ONLY device, no network operators or anything like that...
The flashing process went smoothly and all seems well, except that when I connect to a wireless access point, I don't get an internet connection. It connects to the wifi ok, but no internet.
If I go back to my nandroid backup the internet works fine. There aren't any posts in the rom thread about this issue so I suppose it must be an issue with my device rather than the rom. I assumed flashing the rom would change all my settings to those of the rom, so I don't understand how this can be so.
Any thoughts??

I'm the developer for this rom and I've never heard of any issues like this before. Do you have a player 5 or player 4? Does everything else work fine? It might be worth doing a wiping data, cache and dalvik cache and then re-flashing the rom.

Hi Supermaster34, thanks for the reply, yes, I have spent a fair amount of time reading through your thread and came to the conclusion that this was an as yet unseen problem.
I have a player 5 international. I have reset and wiped everything there is to reset and wipe and I have reinstalled after trying this too.
Before flashing your rom I was/am using eryigits gingerbread rom and I replaced the wpa_supplicant file so that I could access ad hoc networks. I don't know whether this could be relevant or not.. I would have thought that flashing would replace that sort of thing anyway but I thought I'd mention it just in case something not flashed is affected by doing that.
Hope you have some cunning ideas....

I also have a player 5 international and I can't seem to recreate the problem. Maybe the issue is with your player but I doubt it. Try flashing my CM9 rom (link is in my signature) to see if wifi works with that. The wpa_supplicant you replaced would have been replaced with the ICS one upon installation. If you downloaded the rom from the team remics website then the download may have become corrupted for some reason. It might be worth re-downloading and flashing again.

Ok, I'll try re-downloading and I'll also try the CM9 rom... I'll do that tomorrow and then post back here when I find out what happens...
Until tomorrow then..........
Ok, I've tried your CM9 rom and it's the same.. It connects to wifi but there is no internet
Trying the freshly downloaded remics rom now...
No joy...It's the same
What could it be? It must be something on my player that doesn't get flashed (on the internal sd card maybe?) which interferes with the newly flashed files regarding internet... right???
Oh, when I go to wipe dalvik cache I get 'E:unknown volume for path [/sd-ext]' Then I click 'yes - wipe' and it says it is wiped. Is that normal?
restoring my nandroid backup........ and........
Yep, internet is usable again....
What's going on?
I have now also tried with this cm9 rom : Paranoid Android
and I get the same result!!!
Someone else in that thread seemed to have the same problem but no-one replied to his message.
So it's not your roms Supermaster34. It could be cm9 or maybe ics itself, but what is different with my player compared to the hundreds of other people who don't seem to be having any problems?
Formatted internal sdcard and still no joy.....
could it be something to do with the router or encryption being used (I'm on a work network so god knows what's going on at that end of things)? gingerbread can connect through it but cm9 can't? I need to try another wireless access point...
when i had cm9, i only could get internet on my home network, which was secured.
at school, it didnt work on their unsecured network

I think it is far more likely to be a network thing.. Something about my work network and your school network has a quirk that cm9 doesn't know how to deal with. My work network is secured with wpa2, so it probably isn't an encryption issue.
We also have an access point secured with wep which I'll try out tomorrow (same internet coming through it though)..
I'll also try cm7 and see if that connects and I think I'll try flashing a fresh gingerbread as well which should work seeing as my nandroid backup works (just to check it isn't a flashing issue or something).
Next week I'll have access to another access point with a different internet connection (which I'm actually in control of myself), I'll try that one out too...
My oh my, so much to do..............
I dont thing it has anything to do with rom..i have similar problem on another device ..my mein internet is over 3G (HSPA+ i have unlimited data) so i use tehtering on android phone to give internet to my other devices,and it works fine for SGP 5.0 ,laptop ,pc and S7 tablet..they all see conection and internet works..BUT i bought nexus 7 and on my huge disapoinment it could not connect to internet on same connection (and i dont have other) ,consider nexus 7 is wifi only i did not what to do,it sees connection but no internet,then i try different roms all the same no internet.
So i connect laptop via usb tehtering to android phone and via program called connectify create infrastructure hot spot on laptop and then nexus 7 net works ,but my laptop must be on.

Well, I tried flashing a fresh gingerbread and internet works fine (as it does on my gingerbread nandroid backup)... So it isn't a flashing issue
I also flashed CM7 and internet works fine....
So it seems this issue is a CM9 issue (as it appears on all variants of CM9 that I can find).
From all the evidence, it seems to me that there is something about the internet connection at my work that CM9 cannot deal with. It is not a wifi issue as such, as I can connect to wifi, I just get no internet connection.
I haven't actually checked to see whether I am able to connect to a different internet connection elsewhere, I'm assuming I will be able to as hundreds of others seem to be having no problem at all with CM9. I'll test this next week when I have access to another connection.
I work at a school, so just as iurnait a couple of posts back, it is a school network that is giving me problems and school networks can have all sorts of quirky filters etc attached to them to 'protect' the students from who knows what. For example I know that some websites are blocked by open DNS on my work network - is there an issue with CM9 and this sort of filtering?? I have no idea what else there is on the network here as the network admin is rather unfriendly and unhelpful.
DZonikg: it seems that your problem may be different, as mine is rom dependent and yours isn't.
It's a shame as I was really looking forward to my Ice cream sandwich!!
maybe this is related to the brand of router used?
it seems like some unsecured locations work while others dont. i was at a supermarket and i connected fine but i couldnt get it to connect at another place.
Mmmm-) what brand of router is at your school? i have netgear at home and i can connect.
or it may do with the channel of the router. i dont have cm9 on my device but try using WiFi Analyzer (Play Store) to see what channel your connection is.
I had this issue with both paranoid and supermasters cm9 Rom.
Actually I sent you a pm supermaster back in sept about this issue. The device would connect and the wifi icon would show the bars but they would be greyed out.
Since I don't have the post count to post in the dev thread I kept checking back on the threads to see if anyone one mentioned it but the guy in the paranoid thread got ignored and that thread seems dead. And no one mentioned it in supers CM9 thread. So I just said fug it and slapped on my stock ROM.
Hang on a minute...... I've got internet !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Whatever happened???
I was trying to update my media library but apparently you cant with ICS and so i had to 'clear data' in the media storage app so I did this and rebooted... and as if by magic I was connected to the internet. When I rebooted I was already connected to wifi (but obviously with no internet connection).
Since then I've got everything set up and done a nandroid backup rebooting again and I still have the internet.
I really don't get how doing this would have solved the problem...but something has solved it... Maybe something changed on the network...who knows....??
Im away from work for a week from tomorrow, so I won't know if it is still working until then.... I'll tell you if I can still connect in a week....
Try McDonald's a dunkin donuts if you live near one. They have free wifi if you want to test it out. If you saying is working I'll give it another shot.

I had a good connection for a couple of hours and then it just stopped! I cleared the media storage app again and rebooted and I have internet again!!!
I still can't believe it can be a fix - it must be an odd coincidence... If it works one more time I'll believe it...
Well it happened again but I'm afraid to say that no matter what I did I couldn't get the internet to connect again, so it must just have been a coincidence...
The good news is that I am now connected to the internet on another connection (far away from work) and have had no difficulties whatsoever. So I'm certain that it is some quirk with my work network. Although the fact that I can connect to it with gingerbread suggests that rather than it being a network problem, it is an incompatibility with ics or cm9. Can someone fix it please?
One quirk of CM9 on Galaxy Players is that it has MUCH poorer wifi reception than Gingerbread. If your wifi connection was at all weak, you'll get connection issues with CM9.

I don't get Wi-Fi connection issues at all,I just get internet connection issues. The signal is fine and it connects to the wap with no problems at all.
