ubuntu 10.10 no wierless connection with Dell XFRd630 with 1395 WLAN Mini-Card

Hey, I installed ubuntu 10.10 and everything worked fine for two days (and I fell in love with linux) but now I can not connect to a wireless connection. Did I mention I am new to linux and have been working on this problem for a couple of days. My wireless card is 1395 WLAN Mini-Card I think I have the b43 driver installed. I have reinstalled the driver and linux but to no effect.
Need help

Well, this part of the output

shows that the b43-pci-bridge module is loaded for the device. Could you please post the output of

Code:

sudo iwconfig

Markus

lo no wireless extensions.

eth0 no wireless extensions.

If I understood your first post correctly, you have been connected to the wireless network? and now the connection is lost?

The output of iwconfig shows, that your computer is not connected to the wireless network. How did you once connect to the wlan? do you have the SSID (networkname) and the encryptionkey available?

Do you know which encryption your network is using?

Markus

first time I installed linux I was able to connect without an issue (once I chose the network punched in the web key and connected) it worked for about two days and then it just would not connect just like now the connections are visible the web key is correct but it keeps on trying but with no effect. I tried re installing the drivers many times and I re installed linux to see if it's going to work like it did the first time but no it did not.

I used the standard settings and later I did play around with the settings, erased the the connection settings even un installed and reinstalled the manager but to no avail.

Reinstalling will be no solution. Which encryption do you use? wpa2? which which tool did you configure your network? Did you change any programs?

Do you use DHCP?

Oh and connection works fine in windows, i have dual boot.

could you please boot Windows, open the commandshell (Start->execute->"cmd" <ENTER>) and post the output of

Code:

ipconfig /all

Markus

How do I find out about the encryption, I think it is wpa2, but I would rather verify

if it is wpa2, you'll need wpa_supplicant to connect. Did you edit the wpa_supplicant.conf file once you connected successful to the network?

Markus

Ok give me a second
