YES!
Finally, somebody else sees this as well! I already talked to quite a 
few people and nobody ever experienced this...

I frequently travel with my Thinkpad (ARTEM WLAN card, 1.50 ARTEM 
driver, WiFistat) between two networks. My WLAN card has a different 
(but static) IP address in both networks and the default gateway and the 
subnet are different as well. From time to time, the reconfigure of the 
interface fails, in a way that I cannot ping ANYTHING anymore. Not even 
my own IP address of the WLAN card. I tried flushing ARP and ROUTES but 
to no avail. I cannot predict when the reconfigure will fail, but 
usually not in the order of the first or second reconfigure but rather 
after the 10th or 15th time.

The only thing that helps is a reboot of the Thinkpad. If somebody has a 
solution for that problem, that would be great, since this is currently 
the only reason for me to reboot the Thinkpad after a couple of days of 
work...

Regards,
