Hello Ubuntu Gurus
Before posting this message, I already tried to troubleshoot,
unfortunately without any result. :-(
I spent hours on Google and found no solution. You guys, are my last
chance! :-)
Here the situation:
- two PCs with a fresh and up-to-date install of Ubuntu 9.10 -
2.6.31-15-generic
- two different wireless networks without any restriction (no MAC
filtering, no WEP, no WPA, just an open network)
- two WLAN USB-sticks from Zyxel, mod B-220 (zd1201)
When starting Ubuntu, or clicking on the NetworkManager Applet (ver.
0.7.996), all networks are correctly detected and listed. NetworkManager
tries to connect the network for about a minute, and then fails.
I tried to replace NM with wicd. Wicd connects to the network and a
fraction of a second later disconnects.
- other PCs with Ubuntu 9.10 and 9.04, with integrated WLAN card, have
no problem to connect to the same networks.
- both Zyxel B-220 have no problem to connect the same networks on a Win
XP laptop.
- both Zyxel B-220 USB-sticks have worked well on Ubuntu 8.04
Yes, that's weird! Any ideas?
Many thanks in advance for your help!
Frank
