Bug#505152: firmware-ralink: Workaround found for D-Link DWL G-122 hw81 freezes
Package: firmware-ralink
Version: 0.30
Followup-For: Bug #505152
workaround found:
"pre-up iwconfig wlan0 power off"
in relevant interface confs lines (in /etc/network/interfaces).
Note: I don't know how to make that in a graphic interface.
So, I think it is an energy-saving feature wlan interface problem
(details in paragraph below).
Product label: "D-Link DWL G-122 hw version 81 fw version 1.00"
Without that workaround SSH is almost unuseable, and if not used a
while, the link goes definitely down and I have to reboot (I have
no console: the machine is a "just mpd enabled jukebox", with
even no MTA). mpd clients were unuseable too but lftp clients
worked fine while transfering files (=> works at high throughputs,
but not at low ones).
relevant dmesg lines (while pre-up is ok):
