random wifi disconnects

Lately, every few hours, I'm disconnected from wifi.

messages.log says:

Happens with wicd & with manual connection (wpa_supplicant etc), too.

Anyone an Idea why / what to do? Thx!

Re: random wifi disconnects

Same problem here.
I tried to downgrade nettools. But it didn't help.
