View Full Version : [ubuntu] Dell D830,BCM4312, 8.1.0 connecting with WEP

January 19th, 2009, 08:42 PM
I am having some issues with WEP connections using network-manager and the b43 driver. I have been doing a lot of reading on this forum and I am not sure if I should be trying to use the ndiswrapper setup, or stay with the b43 driver.

I can connect to my home wireless Dlink DIR-655, the router is set to wpa or wpa2, tkip or aes. But I cannot connect to my works WEP network. When I enter the wep wireless settings, network-manager tries to connect but fails. I have tried the STA driver that is in Admin --> Hardware Drivers, but can't connect to any network with that driver.

Any help is appreciated.

When I use the STA driver to connect to my home WPA/WPA2 network I get prompted for the password to join the network over and over again.

Well, I did get the b43 driver to connect to my works WEP network one time with network manager. What seems to be happening is that NM doesnt always see open wireless networks. When click on the NM icon, sometimes I see open network signal strengths and sometimes I dont. I have to use sudo /etc/init.d/NetworkManager stop and start to see them again.

Also, iwlist wlan0 scan doenst show networks even when NM does see them.

Help please!

Still using the B43 driver, removed network-manager and installed wicd.

Everything is working great now.

Thanks for all the help!

Post #3 worked for me!

Just copy paste this

sudo apt-get install b43-fwcutter

The rest is done for you...then reboot. Works perfect after that.:popcorn:
