Hello, i can confirm this too.
laptop:
- new DELL Inspiron 6400
- Intel PRO/Wireless 3945
- Intel Pentium Dual-Core CPU
- distro: ubuntu Feisty
- kernel 2.6.20-16-generic
windows: wlan working.
i don't think that the wlan-router (Vigor2500) because with other
notebooks (intel wlan too, feisty too) i can connect without any
problems.
ethernet is fully working.
reinstalling feisty did'n work. also live CD - same issue.
connecting with network-manager really a problem. also without WEP.
Always i can see the aviable wireless networks (also mine) in the
network-manager-applet (with great signal) but only in 1 of 12 cases i
can connect. and then the connection is very very slow.
I tried manual configuration, without natwork-manager and with static
IPs. Since then connecting is now Problem. But the connection is very
very slow, too.
iwconfig eth1:
