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.

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...

Was any progress on this problem? Adding ipw2100-devel@lists.sourceforge.net to help out.
Thanks.

please attach your dmesg (load ipw2100 debug=0x43fff).

Comment 8 Adrian Bunk 2007-09-16 13:16:28 UTC

Please reopen this bug if:
- it is still present with kernel 2.6.22 and
- you can provide the requested information.
