Description Subodh Shrivastava 2005-12-04 06:13:41 UTC 
I am using wpa_supplicant for WPA-PSK key management. in-kernel driver manages
to associate itself with the AP, but after few minutes it disassociates itself
and then reassociates itself.

Comment 3 Adrian Bunk 2006-04-22 09:48:52 UTC 
Is this issue still present in kernel 2.6.16?
Comment 4 Adrian Bunk 2006-08-06 03:46:25 UTC 
Please reopen this bug if it's still present in kernel 2.6.17.
Comment 5 Vincenzo Ampolo 2007-05-06 18:33:29 UTC 
Please reopen this bug since it seems still alive in kernel 2.6.20

I'm using ubuntu feisty and dmesg says:

[...]

when i try to connect with wpa_supplicant this is the output:

[...]

It seems that the firmware/driver of ipw2100 detect a "beacon frame lost" like a
disconnection...

Please contact me if you need more data...
