Hi!
My WLAN net goes down from time to time. I cannot ping the wlan/dsl-router
(T-Sinus 111) and the only thing that helps is re-load the kernel-driver
(ifconfig eth1 down; modprobe -r orinoco_pci;
sleep 8; ifconfig eth1 up; iwconfig ...)
Changing speed (down to 1 Mb/s) does no better
Bisides this, I have annother problem: This f***ing router mentioned
above cannot handle at least one connection per second in the long run
(>30 minutes) and crashes in the way, that it still may be pinged, but
I cannot access the router's web-interface, nor can I get to the internet
and have to power-cyle it (official advice from the company selling it!)
I tried hard to see these problems as one, but it seems, they ARE
two (see logs)
Here is, what I can offer you as info:

Thanks in advance for any help you can give me!
I'm having similar problems with a PCMCIA orinoco wlan device. Works
perfectly with various 2.4.X kernels but keeps (partially) dropping the
connection with 2.6.X kernels. By partially, I mean connections are
lost and pings report target hosts as unreachable but netstat -r reports
make it look like the connection is still valid. Doing an ifup (without
a preceding ifdown) seems to fix the problem.
If more information would be helpful or testing is required don't
hesitate to ask.
Peter
