[ipw2200] Wireless Connections are dropped every 60 seconds

[Markus Kienast]

I get disconnected repeatedly from my unsecured WLAN. It happens about ever 60 seconds. I recognized that while downloading larger files as well as while making VoIP phone calls with Skype or SIP based phones. Sometimes I get over one cycle and am connected for up to 2 minutes, amazing isn't it.

I suspect that this happens because NetworkManager or something else (wpasupplicant) tries to update it's list of available networks. Seems like this just takes a little to much time and the AccessPoint, kernel or the application looses the connection.

NetworkManager however acts like nothing happened. Maybe it is different when a WEP key is involved. I also thought, maybe powersave or laptop mode have something to do with it.

This needs to be investigated, since it renders the WLAN connection useless for VoIP and normal large file downloads.

Are there any connection/disconnection messages in dmesg when this happens?

No! I suspect this is below that level. As I pointed out, it might have
something to do with the driver or other software filling it's lists of
available AccessPoints. Or it might have something to do with powersave mode.

Just filed Bug #40315. This might have something to do with it but not
necessarily.

Actually, listening to the drop-outs of my skype communication there must be some periodic event more in a cycle as short as a second or 2.

Hi elias,

Do you still have this issue with an up to date Dapper, or with the Edgy Beta? Thanks in advance.

[Markus Kienast (elias1884)]

no

Closing this bug as the reporter says that the issue has been resolved.
Thank you.
