wireless LAN problems with recent kernels
I'm using a RaLink RT2500 (PCI) wireless NIC. It works without problems
with a 18.104.22.168 kernel and the rt2500 drivers.
I did try to update to the Debian 2.6.25 kernel, but there the WLAN
connection makes problems: Sometimes the connection just drops.
dmesg shows this message:
wlan0: No ProbeResp from current AP 00:13:49:d7:ab:7c
- assume out of range
The connection is not reestablished automatically, only when I run e.g.
`iwconfig wlan0 essid MyESSID'. This reconnection also fails sometimes
with the following message showing up in dmesg:
wlan0: authentication with AP 00:13:49:d7:ab:7c timed out
I admit having sometimes connection problems running the older kernel as
well, but the network works again after a few moments (and without any
manual intervention). The link quality given by iwconfig is around
50/100, though it sometimes goes down to 30. Anyway the situation is
much worse with the newer kernel version.
A forum post  suggested increasing IEEE80211_MONITORING_INTERVAL in the
kernel sources, but this didn't help much: The messages do no longer
appear, but the connection is still flaky.
