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.

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.

does this work for anyone? i have never been able to on my 101
I have no problems connecting to my unsecured network at home (don't worry, there's only maybe five houses on my street that could even reach it!) How far can you get in connecting? For example, will it see the network when you scan? Will it fail when you try to select it? Will it select, but not have a web connection?

Never had a single issue. Are you sure it's not Adhoc or something? What channel is the AP?
i've been unable since i first bought it... and ive updated firmware and done full restores before.
it connects fine but doesn't actually have internet once it does. happened on a few different networks but most notably would be my phone when i made it a hotspot it would work fine if i put a password on but wont if i do it unsecured

I have to reconnect to my phone sometimes when using hotspot, seems like the routing breaks every once in a while, but I connect to multiple unsecured networks(actually using radius auth, but that won't change anything) on a regular basis. Sorry, I can't really think of anything that would cause that even after reformatting. I'd start looking at the dmesg logs for an error.
I'm going to start here with this question before expanding it to the whole xda-developers Q&A area, since this is something I am trying to do specifically with my Note.
Is there a way to force an app to use mobile data connection (MDC) instead of wifi?
Specifically, I am trying to figure out if I can force Activesync and/or the Gmail app to use the MDC instead of the wifi connection when I am already connected on wifi, especially if there is a way to have either of those apps detect that it can't communicate with the servers through wifi, and auto change to using the MDC.
Reason for this??? I need to receive emails through Activesync and Gmail at all times, due to being on-call for work. The wifi connection screws up sometimes, but the phone stays connected to the wifi thinking it can still access everything ok. (yes, it is a problem with the router, not the phone, and that is being investigated separately)
Yes...I know I could just turn off my wifi connection on the phone, but I prefer to leave it on if possible, and just use the MDC for those two apps. Is that even possible to use the MDC while still connected to wifi, or is there a requirement that wifi be turned off to use MDC, no matter what???
Also, what is the proper name for the MDC? That might help me search for a solution. MDC was the best I could come up with for it, but maybe there is an "official" name for this connection?
I have the Tasker app installed, and have been thinking about trying a way to make Tasker cycle the wifi connection for me, but as I said, I would prefer to just leave the wifi turned on, and just force those two apps out the MDC.
Any help, or maybe just point me to some more info? I have search for about a week now, and am finding plenty of people asking how to restrict an app to use wifi, but not the other way around.
Thanks!

Additional info:
Think of it this way...the wifi issue may be firewall related. So, the firewall stops my phone data from going to the internet through wifi. I need to still get my emails though. I would like to stay connected to my wifi, so that I could tell that I am having problem as soon as I try to surf the web, but my emails would still be coming through because they are using the mobile data connection instead.
I've never seen a mobile data connection stay active while wifi was turned on and connected.
Your best bet is to either fix whatever is wrong with your wifi connection, or bite the bullet and leave wifi off, until you can fix your wifi connection.
i agree, dont think its possible to use data connection,without turning off wifi first(impossible to have 2 data types simultaneously)

I dont think its impossible, as I believe txts come over data, not sure on this though. Is it possible to get what you want, yes most likely. Is it going to be easy, probably not. Address the real problem rather then applying an over complicated bandaid.
If your staying connected, but losing data at home then it is likely your modem is the culprit (assuming you use a modem connected to a wireless router, not a all in one device). If it belongs to the cable/phone company then contact them. If you bought your modem, find out what is compatable and buy a new one and see if this fixes it. I had the exact same problem with Time Warner the dumb asses tried telling me it was my wireless router problem despite still being about to be 100% up and running on internal (streaming music and movies from plex server while on phone and even able to RDP internally). Eventually they agreed to send a tech out and he laughed at them and gave me an upgraded modem and we were good to go.
Thanks for the support, but as I said, the wifi issue is being addresses separately. It may not be a quick & easy fix, because additional "testing" is being done on the network (firewall) that may be the real cause of the issue. It is being looked into though.
So...for everyone trying to get me to just "fix" the wifi first, sorry, but it isn't going to happen right now. I would just like to find a way to do what I requested in the original message.

Does that help clarify my need of this some?
I agree that it seems only one connection can be active at a time. On my windows mobile phone it defaulted to the data connection, android seems to default to wifi (i would bet this is a requirement from the carriers).
As for texts, they are delivered through spare bits on the cellular carrier channel that were left as spares very early on. Not via data channels. Which is why forcing us to pay to send texts is such robbery - we are literally using otherwise spare bandwidth.
How to bypass MDC?
I have a similar need as MonkeyThumper. My situation is that I have a camera application which allows me to view my camera's at home. It uses port 2000 of which our corporate firewall blocks. I have to turn off wi-fi so that I can use mobile in order to connect. Wondering if there is some routing protocol that I can tell my phone to use MDC instead of wi-fi specifically for that application. It's a nuissance to have to turn off wi-fi, check the camera's, then turn it back on regularly. Any help would be greatly appreciated.
Apps = Not Likely. HOWEVER.... and I can't say for sure - mainly because I have no idea if the radios shut down based upon connection (example 3G turns off when on wifi) - but you can modify the routes in the route table and (again in theory) force data down one pathway or the other.
For example - using a terminal on the phone try this: Connect Wifi - then in the terminal type: ip route show
Output will be something like
default via 192.168.1.1 dev wlan0
....
192.168.1.1 dev wlan0 scope link
Click to expand...
Click to collapse
If you disconnect Wifi and repeat (ip route show) the output will look like this:
default via 10.77.xx.xx dev rmnet_sdio0
...
10.77.xx.xx dev rmnet_sdio0 scope link
Click to expand...
Click to collapse
So, you should be able to manipulate the route table with something like:
su
ip route add 88.77.66.55/32 via 10.77.xx dev rmnet_sdio0 (where 88.77.66.55 is your home IP address or the IP you want to get to).
The problem with this is... it's not persistent. So you'll be best off doing this from a script or something once you verify it works.
There might be another way too... I'm sure there's a route file somewhere that can be configured.

Need GMAIL on Mobile Data, others on WiFi
hi, my case is simple:
At work, we have WiFi.
But, GMAIL is blocked.
So, i want all my other apps to use the office WiFi, but gmail to go over my mobile data.
I would imagine this scenario is getting more and more common.
Does anyone have any ideas here, apart from having to turn wifi off everytime i want to check my gmail?
any help much appreciated,
thanks James.

but my phone runs soooo good, im bored
been trying to decide what to flash. even if there are issues, it will give me something to do.
For some reason I am unable to connect to my home WiFi network. It acts as if it is about to connect by saying authenticating and then stops and does not connect act all. Then after if I try to connect to the network again it says "Failed to connect to network". I have noticed this has happened to me before when I flashed the Viper ROM so I just went back to stock. I do not know why this issue is occurring.
Try fixing permissions in recovery. This appeared to work for me.
Something else to check is the setting called "Keep Wi-Fi on during sleep": System Settings --> WiFi --> Menu --> Advanced. Try a different setting and see whether that works.

I was trying to follow his instructions to check for modules but it seems to be over my head. I dont have much experance with adb. The last time I flashed the kernel i wiped cache and dalvik before and after and fixed permissions.

WPA2 on both home and work routers. That's not the issue for me. It seems that when I try to connect manually, it fails. When Android connects by itself, it usually succeeds.

I have an Asus Slider Sl101. Around 3 days ago, our router had been changes as the previous one wasn't working properly. Our carrier is Charter and our router is Netgear. We hooked every device up to that new router and everything worked fine, including the tablet. But later on in the day,the Internet on there stopped working.
It shows that it's connected, but when I try to access the internet through the browser, it does not work. The blue line at the top of the browser starts up, moves forward a little, and stops entirely while the browser then says "Webpage Not Available". Apps that require Internet, such as Accuweather and my SAT apps, fail to work as well. Other devices that use our wifi include another computer and Nintendo DSi and 3DS. They all work fine. Our router shows that our android is connected to it, as well.
I've tried the static IP stuff, restarted the router, left the wifi off on the tablet for a few hours, and turned it off and off. I even factory resetted it and not even that helped.
I apologize in advance if I haven't given enough information; that's as much as I know save for whatever I can include from the tablet (IP Address and such).

It can be modified from the admin panel of your router. Obviously, each connected device must be upgraded to the new encryption method.
However, you can simply do a test and see if the connection works

If the problem is not of the device, many network problems are usually caused by encryption or are due to the channel where the router works. Both settings are settable in the admin panel.

The things is, though, my tablet was working when we changed the router. Ever since then, nothing has changed when it comes to settings and all. Every other mobile device is working well and the computer out front that uses wifi works well.
In your eyes, the router seems to be the main problem, right? Do you think if we call our internet provider--Charter-- and ask for a new one that it might be able to work as it will be new and all? Or will it most likely not help too much?

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.

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?

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)

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.
Sorry for my bad english...

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.

Yeah, I'm suffering from OCD and just to make sure the bug doesn't carry over to the next ROM i flash, I formatted my phone through recovery before flashing the .tar firmware in ODIN. And I tried 2 different firmwares and still same thing. Now on MF6 stock 4.1.2 and trying to avoid stock 4.3 because of Knox bootloader.

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.

Ok try using airplane mode when you are standing at a distance and check if the wireless connection continues.

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)

Unfortunately I'm not the original owner of this S3 so I can't be sure if the previous owner flashed any custom ROMs.

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.
