Serious wifi help needed.

post #1 of 13
Thread Starter 
I can't figure out why but for some reason my school WIFI (WPA2) keeps kicking me off. Now this is not a hardware issue as at my home I have no problem keeping a connection all day but here my university seems to kick me off within 5 minutes. Is there anyway to fight this? I have all the right settings and permissions (as for as the school IT guys are concerned) yet still I'm the fastest at loading a page and the only one getting kicked off constantly. Any idea what I can check and how to go from there?

Can you post the output of
Code:
lspci

How you do define being kicked?
Service refusal? Time outs?

My first step would be to have dmesg | grep wlan0 (or ath0, depending on your configuration and such) as well as dmesg | grep (insert module name sans extension here)
Any information you find that way is going to be the most useful for troubleshooting. Its possible that due to a non-standard wifi implementation they are inadvertently preventing you from maintaining a WiFi connection. It is also possible that they are expressly kicking *nix clients at a set interval, but that's highly unlikely, as most institutions don't care, and probably use some *nix based something somewhere.

Thanks guys for the replies I'm sorry I was in my 3hour finance lecture and just finally got home.

What I mean is that after a few minutes (usually 5 or less) the connection would just cycle as in...I lost the connection and then Network Manager would immediately try to connect again and then connection is made and then repeat from the beginning.

@xaero: I assume I'd need to run the first command when on the network in question to get relevant info right?

However...probing the module/driver I think comes out just fine as this:
Code:
dmesg | grep iwlwifi

[   46.444332] iwlwifi 0000:03:00.0: Radio type=0x1-0x2-0x0

On a side note...I'm trying to investigate whether this is the "enterprise" WPA bug that seems to wreck havoc on iwlwifi and Intel wifi cards. Seems that iwlwifi has actually been pretty bad this past year from what I saw in some Fedora bug reports and other places.


On a hypothetical backup plan...would ndiswrapper somehow be available to use the windows driver for my Intel card...you know if this not fixable?

Thanks again guys.

Thanks again guys.

You assume correctly, both dmesg results would only provide additional information in the case you had been connected to, and lost connection to the wifi. This would provide you with some information to go on, I suggest dumping both dmesg | grep iwlwifi and dmesg | grep wlan0 after the disconnection happens, if its a driver specific issue, it could be presented in either log output, since it could be a kernel module message (iwlwifi) or it could be a standard linux wireless message (wlan0) At any rate, it'd give you more to go on than just knowing that you get dropped.

Imo, wait until the next time you get dropped, and run both dmesg's and see if you can find any relevant info (you probably will, since these things are still pretty verbose) And then you can probably identify whether or not its directly associated to the iwlwifi driver bug, or if its something new entirely.

Looks like either a network manager bug or th kernel iwlwifi regression somewhere around kernel.version 3.2

What version of kernel and network manager are you using?

If you can try rolling back to a 3.0 or 3.1 kernel, or updating to a newer version of network manager, that may fix the issue, upgrading to a more recent kernel (post 3.4) may fix it as well. Also, there was a Cisco/Intel conflict with your specific wireless chipset, that was supposed to be fixed by intel a long time ago... This doesn't appear to be the same issue, but its still worth trying; one workaround is to disable MFP infrastructure authentication on the cisco side (which probably won't work since you aren't the network admin) the other workaround is to connect using 802.11G or lower with 802.11N disabled on the wifi chipset. The issue specifically affects 802.11N if the driver is the cause.

What version of kernel and network manager are you using?

If you can try rolling back to a 3.0 or 3.1 kernel, or updating to a newer version of network manager, that may fix the issue, upgrading to a more recent kernel (post 3.4) may fix it as well. Also, there was a Cisco/Intel conflict with your specific wireless chipset, that was supposed to be fixed by intel a long time ago... This doesn't appear to be the same issue, but its still worth trying; one workaround is to disable MFP infrastructure authentication on the cisco side (which probably won't work since you aren't the network admin) the other workaround is to connect using 802.11G or lower with 802.11N disabled on the wifi chipset. The issue specifically affects 802.11N if the driver is the cause.

Which is what I feared after finally finding some info on this problem from other sites. I'm on the 3.5 line (buntu 12.10). How do I check which version of NM I have? I'm also betting this school is using Cisco. Well, I'm not sure if I understand naming correctly but I've never seen my connection be anything besides the b,g, or a bands. The thing I still don't get is why their non-WPA connection also does the same thing. I have WPA2 and WPA at home and I have no problems but here at this school their entire network seems hostile since I got a laptop with an Intel card. My old netbook had less problems and that was with a Ralink/Atheros.

Still in case I don't find it myself....is there any chance I could try ndiswrapping the windows Intel driver to get around this issue?

apt-show-versions network-manager (if thats the name of the package on your distro)
pacman -Q network-manager
etc...
You can always try ndiswrapper, you'd have to blacklist the iwlwifi kernel module; you can also try pulling a dev iwlwifi module, but it may or may not compile/work due to the age of your kernel.
