strange Wireless Problems

Hi,

I'm using Linksys WPC11 PCMCIA-wlan-Card which works fine with my Suse 9.0
box. But when I'm trying to transfer big Data it looses the connection. In
KNemo it still shows it would be connected but it doesn't work anymore. Then
I got to plug it out and in again and it will work again. Why that? How can
such a thing happen. To me it seems like it would cancel when there is a
steady dataflow to transfer..... it never cancels the communication when I'm
just surfin' arround in the net.

Thank you for suggestions and solutions!

Q: After a few minutes of use, my card stops responding! I'm using WEP.

Too bad, my first answer was the best... :-)

Have you checked your frequency for other WLANs? Are you experiencing any
packet losses when the load is low? A nice tool, mtr will tell.

What does your logs look like, just before and during "it looses the
connection"?

I've experienced runnaway dhcp-clients to cause problems when using the
wlan-ng (prism2_xxx) driver. A manual "ps aux | grep dhcp" and "kill PID"
does the trick. (As the first step, _after_ obtaining the initial IP
address)
