problem connecting wireless internet

[infogirl]

Hello,

i have reinstalled xubuntu from cd successfully (i hope). But i have problem connecting to the wireless internet. It shows a list of wireless connections. I click on my home wireless network and enter the right password but it fails to connet.

I have had previous version of xubuntu and it worked perfectly... if it helps my computer is samsung rv 508 and my second OS is windows vista (by the way wireless network works ok with it).

I have no idea what to do. I'm actually new at open source OS but i really like it. Can anyone help me? Please ...

@infogirl:

Deactivate the Power-management via:

sudo iwconfig wlan0 power off

Check, if your router allows new clients (MAC-filter off!) and if the encryption is WPA2-AES, not mixed WPA/WPA2 or even WEP or non-encrypted. Additionally you can/should deactivate the hardware encryption of the driver:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k
sudo service network-manager restart

Check after that:

iwconfig
sudo iwlist scan
ifconfig wlan0
dmesg | grep ath
rfkill list

Please show all the outputs. You both can also copy the outputs into a text-file and upload it.

Hi,

thanks you very much

PS I also tried "sudo apt-get install --reinstall bcmwl-kernel-source" but it didn't work...


I also post this,in case it might help:

problem solved!
"sudo modprobe b43" did it...


actually, I tried this before but without disconnecting the Ethernet cable and it didn't work

thanks anyway for your time
