I tried uninstalling network manager and connecting manually but it didn't help at all. Nothing changed. My steps: - I boot the Ubuntu 7.10 live CD - I go to Applications--> Add/Remove, uncheck Network Manager (i.e. uninstall) and OK - After succesful uninstallation, I open a terminal and do the following: ====== TERMINAL ======= ubuntu@ubuntu:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions. wifi0 no wireless extensions. ath0 IEEE 802.11g ESSID:"" Nickname:"" Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated Bit Rate:0 kb/s Tx-Power:18 dBm Sensitivity=1/1 Retry:off RTS thr:off Fragment thr:off Power Management:off Link Quality=0/70 Signal level=-93 dBm Noise level=-93 dBm Rx invalid nwid:2297 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 ubuntu@ubuntu:~$ sudo iwconfig ath0 essid WLAN_6A ubuntu@ubuntu:~$ sudo iwconfig ath0 key ********************** ubuntu@ubuntu:~$ sudo dhclient ath0 Internet Systems Consortium DHCP Client V3.0.5 Copyright 2004-2006 Internet Systems Consortium.

The signal strength is about 25%, but under Windows that's more than enough to get an almost rock-solid connection, so I expect at least the same under GNU/Linux. Do you think this is unrelated to the bug being discussed? Or should I stop Network Manager before uninstalling it??? (If so, how do I do that?)
