[NETWORKING] WLAN USB sometimes works, sometimes not

[Benjamin Herbert]

Dear list,

I have run into a problem and would be glad if you could help me.

I have set up a wireless network which runs on WPA. I have a desktop 
computer with installed wireless network USB dongle from Fiberline. 
(zd1211 module)


I set up the current Ubuntu and everything worked like a charm out of 
the box. I chose my network in the Network manager and entered the key. 
Wonderful...so far.

Now from time to time after I start my computer, I do NOT have a 
connection and the AP is not found. But iwconfig still shows my eth1 
WLAN capable.

If this happens, the only way to gain access again is to do 1 or two 
reboots.


The essid is not hidden and there is no mac-filtering. Only the WPA 
protection.

Can you give me some hints about this?



Sincerely
B.Herbert
