645884 - Issues connecting to wireless on Linux

Status: RESOLVED DUPLICATE of bug 681742

(Infrastructure & Operations Graveyard :: NetOps, task)

Description

[Noah Meyerhans [:noahm]]

Symptoms: Initial connection to Mozilla wireless is unreliable.  The wicd gui reports it as an authentication failure, but I suspect it's wrong about this because repeated connection attempts with the same stored password eventually succeed.  The kernel logs the following:

Mar 28 09:34:23 khan kernel: [  162.087621] Registered led device: iwl-phy0::radio
Mar 28 09:34:23 khan kernel: [  162.087651] Registered led device: iwl-phy0::assoc

CC'ing jhford, who mentioned a similar problem using the default GNOME NetworkManager.

Comment 2

[Noah Meyerhans [:noahm]]

Is everybody using Intel wireless hardware?

Comment 3

[Derek Moore [:dmoore]]

Our assumption is people are encountering problems with the iwlagn driver, specifically.

At the risk of sounding like HP Support, is anyone willing to take one for the team and manually upgrade to the latest driver?

i can, though, unlike HP Support, this driver requires the kernel-devel package

Comment 5

[John Ford [:jhford] CET/CEST Berlin Time]

oh, and the exact same symptoms happen for me with NetworkManager

Comment 6

[John Ford [:jhford] CET/CEST Berlin Time]

well, that fixed the problem by totally horking my wifi.  Now i don't get any authentication failures ;)

Comment 7

[John Ford [:jhford] CET/CEST Berlin Time]

I think its worth mentioning that the failing to associate loop continues until NetworkManager finally realizes that there isn't a valid CA (or something else related to certs).  Once I say "ignore", it connects.

[matthew zeier [:mrz]]

On Windows there's a checkbox to ignore cert validation - is there something like that on your OS?

Comment 9

[Arzhel Younsi [:XioNoX]]

The same problem happens to me in my school, ignoring cert doesn't change anything (for that you can try to delete the profile in NetworkManager and recreate it without cert, NM should ask you if you want to ignore cert).

Running "modprobe iwlagn 11n_disable=1 " as root makes things better for me, but not perfect.

Could you try it ?

also having this problem (in toronto), I'm using the iwlagn driver also. I get stuff like this in my logs:
