[Solved] Wireless Network Connection keeps going down

Meskarune · 2015-06-20 21:10:45

I have an Intel WiFi Link 5100 using the iwlwifi driver. The network comes up when I boot and works fine for a while, then suddenly stops. The card is still recognized, but I can't bring up a connection.

Try disabling the power management:

# iw dev wlp2s0 set power_save off

More suggestions here:

Power management is already disabled, you can see that from the output of "iwconfig wlp2s0". It was the first thing I tried. I also tried turning off wireless N which was suggested in the wiki and that did not help either, so I caved and posted to the forums.

D'oh! Sorry...

Have you tried the 11n_disable & swcrypto options?

Meskarune · 2015-06-20 21:59:07

Yep, I have wireless N turned off on my laptop and my router is set to only use wireless G. Still does not help. I think there is something else going on.

Meskarune · 2015-06-20 22:04:30

here is the stuff from journalctl: https://gist.githubusercontent.com/mesk … af9b44/log

Kernel bug here that looks similar:
https://bugzilla.kernel.org/show_bug.cgi?id=91171

It is declared to be a "platform issue" and marked WILL_NOT_FIX

Have you tried the LTS kernel?

Meskarune · 2015-06-20 22:32:43

no, I haven't. I'll install the LTS kernel and see if that helps. If I need to, I guess I can just replace the wifi card with one from an old out of commission laptop. Thanks for your help!

Meskarune · 2015-06-21 12:59:42

I installed and booted the LTS kernel, it's been about 12 hours and the wireless is still up! If it stays up after I run some tests it just might be fixed for now. Thanks Head_on_a_Stick.

Excellent!

You're welcome
