Hi! I installed Ubuntu 9.10 on my Acer 5024wlmi and followed Linux
wireless instructions to enable my Broadcom AirForceOne BCM4318 wifi
card. Now the wireless adapter is on (laptop front led also is on), I
can see wifi networks but connection fails (even with a simple ad-hoc
open wifi network!). I tried with Network Manager/WICD/Wifi Radar and
also using terminal lfconfig/lwconfig commands without success. It
seems that my wifi card cannot ping access points: for example see
this log from WICD connection session:
-2010/01/16 22:51:15 :: Connecting to wireless network Winx
-2010/01/16 22:51:15 :: ping -q -w 3 -c 1 192.168.0.1
-2010/01/16 22:51:17 :: iwconfig wlan0
-2010/01/16 22:51:18 :: Connection Failed: Failed to ping the access point!
Here there are some useful data about my laptop/Ubuntu configuration.
Hope you can help!
