[Q] 802.1x EAP (PEAP) - Wifi connectivity problems

hey folks, i got massive wifi connectivity problems, but only with a special wifi at college.
it's a 802.1x wifi, with EAP (PEAP) and MSCHAPV2.
i configured it correctly (for sure), as i can connect to it manually. but it is not stable, though i got full signal strength. it keeps on dropping after a few minutes with the phone sleeping... when i turn it back on i have to reconnect manually, sometimes i have to deactivate/activate wifi, sometimes it is enough just to connect manually again.
i tried some roms and kernels already, with no effect (arhd 3.1.1, insertcoin from 2.2.1 up to 2.4.3-2 and 2.2.5SSE; kernels were faux 0.1.0 - 0.1.4, bricked 0.2 - 0.4). also stock rom doesn't fix the problem.
i think it's htc based.. somebody else got this problem? is there a workaround availible?

Nobody? Bump...

Hi,
I think it's HTC based too... I've seen this problem with my HD2 and now the Sensation (definitely hoped it was only an HD2 problem but here I am again, looking for a solution).
The symptoms are that you see the wifi connected with, say, full signal, but when you try to open Google Talk or the browser or anything, no data can be reached. This happens particularly when you switch from one AP to another (e.g. walk across compass) or if you leave the network area and then come back.
Do we have similar ones? My school has a registered-MAC network that also doesn't work well with the phone, so I believe it's more to do with how the network infrastructure is set up. However, my friends with non-HTC devices do not report such problems. It's also possible that my similar program installs on both phones do some conflicting with networking, but it's doubtful...
Does anyone have similar experiences?
Edit: It'd almost be preferable for my phone to just drop wifi entirely when the connection fails, since it believes it otherwise has a connection, but everything time-out-s. Having it switch to 3g when it stops working would be preferable to having no networking and no push email or messages...

You can try going into wifi advanced settings and setting the wifi sleep policy to "never", and see if it that fixes it. My high school uses the same 802.1x EAP/MSCHAPv2 security and I also have issues with it, but I think there it's because of such a dense network of access points (there's an access point in EVERY room) it's more interference problems and the phone jumping from AP to AP rather than issues with the phone itself. Download wifi analyzer from the market and check the different access points and if their channels are overlapping and compare their signal levels. If the signal levels are close, the phone might be jumping from AP to AP like mine does.

Dropping WiFi
May not apply to you. But in my case, when I have the WiFi Calling App turned on, I will lose connection to my Home WiFi which is password protected. And when I try to re-connect I have to enter the password again. With out WiFi Calling enabled, I stay connected till I disconnect. Not sure if this would act the same with a different router or without password protection, and since I have a good signal at my house I haven't checked all possibilities.

Thanks for your reply!
I've never set wifi sleep policy to anything but "never," and I've toggled between "Best Wifi Performance" and the alternative of having that disabled.
I've hit in *#*#4636*#*# and looked at the wifi state. It continues to say it's connected with COMPLETED Supplicant State and a valid IP address. Ping test, of course, fails, when this happens.
This happens for me both with mac-registered (insecure) networks and 802.1x networks on campus, but I've found that wifi is rock stable on most home networks, for example...

It might just have to do with the access point interference. I know that my phone has trouble handling the access point switching, regardless of the phone or ROM. My old 3g slide did the same thing. If it only happens on 802.1x networks and it happens on every ROM (which I'm 90% sure it does) then it's probably not something you can change.

I understand that, but the part that gets me is that my roommate's Galaxy S has no such problems.
I've tried many different ROMs when I was on the HD2; I'm hoping I won't have to go through that again!

Oh, then maybe it is a phone issue. I always thought it was just android but I've always used HTC devices. I don't know exactly how 802.1x encryption works, but if it's on a hardware level like some encryption algorithms then it could be HTC specific.

It's definitely a HTC problem. Friend of mine doesn't have such problems as well, he has a SGS2. Everything is configured like it should be, WiFi drop on "never", as already witten in the first post.

Same problem. Connecting at college over EAP with PAP and TTLS. Won't reconnect without upening credential dialong and inputting password

i'm trying to get it fixed by posting some logs to show-p1984, kernel developer of bricked. he is also german, which makes it easier to talk about this kind of 'special' problem for me i will keep this thread updated if there is any solution availible.

That sounds great! Let me know if I can contribute as well (logs? something else?).
I was worried it has something to do with the custom kernels we're all using (i.e. power modes for the wifi and such, but I did edit an HD2 kernel to turn that off and it didn't work). Since show-p1984 is thinking about this now, I'm sure he knows what's up with everything kernel=related to wifi...
When I have time, I'll definitely try a stock ROM again to see how it goes, since there aren't as many complaints about this problem as I'd expect there to be (i.e. ... maybe only us custom ROM users may have this problem with certain wifi infrastructures)...

Hello!
Not sure if anybody's still interested in this problem, but I tried the EU stock rom and it didn't change matters.
Basically, moving around campus makes my phone drop the internet connection on wifi, but not the wifi connection itself. Again, this doesn't happen on Samsung phones, and cycling the wifi fixes this problem.
See attachments for what shows up; it looks like after cycling I get a new lease and it works again.

So do people think the latest bricked kernel fixes this issue?

Unfortunately it doesn't. But at least we have a kernel dev who is aware of this problem. I got no doubt that it'll be fixed one day ;-)

Have you had any luck getting connected? I also have the same problem on my school network.

Still no change... As it's a driver of the wifi module, maybe it'll never be fixed at all. Anyways I hope, that maybe with the ICS update a change will come. Also there is show, who is aware of it.

EAP connectivity issues (ARHD 6.2.1)
I am suffering from this problem also when running ARHD 6.2.1 XE ROM for the senation which is ICS based. Has there been any progress on this?

[Q] [Help Required] Wifi Problem, but nothing seems to fix this.

For a month or so I've been having wifi problems with my phone.
It's one you often see discussed:
either A)
wifi scans, picks up presence of network [with excellent signal strength] then, on click, doesn't try to connect just changes to say out of range.
Alternatively B), it simply doesn't see the network at all despite me being 2 feet from the router.
This happens with my home router [we have two, neither work] and with what seems like every other router too.
I am currently running the 6.1.1 version of ARHD [with android 4.0.3].
I can provide any information that might help, I'm not at all bad with this sort of stuff normally, although not collosally experienced with android.
Thank you for your time.
PS. Steps already tried to fix problem:
Power cycling router, installing different ROMs,scripted wifi fix for 6.1.1, changing wifi channels, switching router to just b and/or g, wifi fixer app, removing authentication, using different router, changed radio, changed kernel, and possibly more.
Please any advice would be fantastic, I struggle to use this phone without wifi.

Try the wifi with your sim in a differnet phone - when that works choose a different rom make sure you go back to a stock RUU before the new rom

I've never been able to connect to a wifi network on my sensation. I've tried it with the stock 2.3.4 ROM, and with all of the ARHD ROMS.
I can see wifi networks, and enter the network password, but it'll never connect.
So I'd be interested in any solution for this problem also.

Have you tried on different routers? I can only assume the routers channel is set to one that the device won't work on? Have you changed your router settings before
Sorry my bad only read half,

OK what is your devices mac address showing up as? Maybe it's the same as another device on your network?
Have you done a full wipe of your device?
Does your bluetooth work? (same antenna as wifi)
Has it ever worked?
Have you tried disabling all your routers security?

[Q]nexus 5 cant find wifi

Hey guys!
So I have a problem with my nexus 5.
Lately it seems as if it does not find "new" wifi connections... It connects to the one it already has saved.
If I click scan no wifi networks appear even though there are many(my pc and other phones get good signal)
I also get the notification saying "There are networks available" but when i touch it no networks appear...
Any ideas?
Cheers!
EDIT: I just tried adding the SSID and it connected fine and works great.... So the problem is the actual scanning...

You say that it happens "lately". So it worked previously? Anything change right before the problem arose? What is your phone's configuration, i.e., ROM, kernel, Xposed, runtime, etc. Have you rebooted the router? (I know, your other devices see all networks, but, what works for one may not for another)

I would suggest that the router you are connecting to is set to not broadcast the SId - simple (but not too effective) security measure.

Same problem here! I got my N5 yesterday and wifi was perfectly connecting to my router. The I unlocked the bootloader and root by using WugFresh's Nexus Root Toolkit and phone is not detecting anymore my wifi network. Phone wifi works since I see the others wifi around but not mine!:crying::crying:
I did the following but problem still present:
- powered off the router
- changed SSID on router setup
- removed security on router setup
- add manually the wifi into Nexus 5
I have no clue on what I can do more....pls help!
EDIT: solved: I noticed my router was set on specific channels for wifi, then I modified to AUTO

If i remember correctly, Nexus 5 version 4.4 had issues connecting to WIFI channel greater than 10.
I had this issue also.

[Q] Is Nexus 5 supports wifi roaming/ changing AP?

Hi,
like in subject is our N5 supporting wifi roaming/changing access point based on signal strength? I have two access points with the same SSID but on different channels. My laptop is switching between AP from upstairs and downstairs and iPhone 4S I had before N5 was switching too. Unfortunatly Nexus is not... Is it supported by our phone or not? Is it at all supported by Android OS?
BTW I wanted to ask another thing related with wifi. I changed wifi option "Keep Wi-Fi on during sleep" to "Never" but it's not turning off when I put my phone in to sleep. How long does it take to turn of wifi after locking phone? Could you check Is this option working for you guys?
Thanks for all answers, Zibiksior

Anyone?

hello and sorry to be late but i didn't actually had nothing to say but i'd had the same issue.
Yesterday frustrated by the roaming not working i tried to set wifi network frequency on n5 wifi advanced settings to 2.4ghz only and volià, wifi romaing seems to work correctly: as i change the room n5 suddenly changes ap without loosing connection.
can anyone confirm?

I will check it today at the evening and report back.
EDIT. Nope its's not working for me. @Riekr what Rom are you using?
Sent from awesome Nexus 5

Stock ROM, anyway I'll check further as it seems to switch from one ap to another but not vice versa. Please also check that all parameter are the same except the channels (as per specs) and that the channels does not overlap with WiFi analyser (to improve performance)

Yes I have the same configuration. The same ssid and pass in both AP's. Only chennels are different and not overlapping also. I'm using now purity rom with Linaro kernel.

Did you manage to fix this? I'm having the same issue.

That option does work and will switch over to your data connection when the phone is asleep. There is an option in the WiFi settings called "scanning always available" which will prevent the WiFi chip from ever truly disabling itself however.

From what I can tell my Nexus 5 changes fine, however I have only tested it on the same router.
I believe "Keep Wi-Fi on during sleep" to "Never" only turns the Wi-Fi off if there is not an active connection currently using data, otherwise things would get dropped packets, etc. Correct me if i am wrong though.

2.4ghz wifi networks not working

Hey guys,
Flashed stock 5.0 on my nexus 5 using TWRP.
After the device booted up, i noticed it could only connect to 5ghz wifi networks and not 2.4ghz.
Any ideas why this is occurring?
Cheers

Same here

Yeah strange. I'll try re-install the stock ROM and see if I notice anything different..

Yes, exactly the same problem here. Funny thing is that I can see the network, but can't connect.
EDIT: So it seems there are multiple issues, found some bug reports related to what I'm experiencing:
https://code.google.com/p/android/issues/detail?id=78702
https://code.google.com/p/android-developer-preview/issues/detail?id=1548
https://code.google.com/p/android-developer-preview/issues/detail?id=1620

Oh ok, I can't even see them. Do you get an error, or the phone just refuses to connect with an error msg?

On WLAN Settings there is a Menu called Advanced
There you can select if 2,4 GHz, 5,0 Ghz or automatically both.
Maybe after putting automatically you see them both?
I seet the WLAN, can put password, but it tries to connect and then stops connecting and always tries to reconnect from time to time...

Thanks guys! I worked it out. My routers 2.4ghz band was on channel 13, I changed it to 7 and it showed up. Don't understand why it couldn't see it before, but now it works! Hooray! Cheers!
If you're having troubles guys, try to tweak the channel on your router

And what if your network at work has above 11?
Then you can't do sh**... Seriously Google

Yeah, WiFi in 5.0 is major screw up. There are at minimum 3 major issues:
- 2.4 GHz band channels above 11 unusable
- https://code.google.com/p/android/issues/detail?id=78702 (or https://code.google.com/p/android-developer-preview/issues/detail?id=1548 reported on developer preview)
- https://code.google.com/p/android-developer-preview/issues/detail?id=1620
And then there was that excessive power consumption related one - supposedly responsible for the 5.0 release delay.
