wireless works w windows, not work w ubuntu 11.10

Asked by Thrylewn

The problem is that my wireless works at some places, but it doesn't work at my home. Windows has no problem at all to connect wirelessly at home. My laptop is a Toshiba L655-1JN. The computer recognizes the ssid name it keeps asking me to enter the password, but it does not connect. I switched off the security but still,it makes no difference.
From the terminal I get the following information:

Please copy-paste each command below one by one into a Terminal. Hit <ENTER> after each command.

echo "blacklist bcma" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist brcm80211" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist acer_wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf
sudo apt-get update
sudo apt-get install wicd

After running the commands above, make sure to select "Load Defaults" in the BIOS, save the configuration.

Then reboot and retest wireless using the wl driver and using wicd network manager.
