WiFi not working after upgrade to Ubuntu 11.04


I am running Ubuntu 10.10 on a Dell Inspiron 1501 and when I upgrade or clean install to Ubuntu 11.04 onto my computer, the WiFi stops working. Does anyone have any ideas that I could try to solve this problem? Thank you.

It is the network manager applet (nm). Should be in your upper right hand corner of the screen. Depends on the icon theme you are using as to what it looks like. Could be a pair of overlapping monitors or a male an female cable ends (some others too), just cursor over them and you should get some text that is related to your current connection.

Right click will get more options.

Please post the output of
Code:
lspci -vnn | grep -a4 -i net
lsmod
Dell's frequently use broadcom cards. If you're using the broadcom sta driver, it may need to be rebuilt against the current kernel. (Or an updated package installed for 11.04.)

See this page from the Ubuntu help site to troubleshoot your problem: https://help.ubuntu.com/community/Wi...Driver/bcm43xx
Quote:
Note: On Ubuntu 11.04 installing the 'firmware-b43-installer' package takes care of the downloading and installation of the b43 driver.

Hello -

Can you use wired ethernet to get to internet to update you packages? 11.04 is pushing out new software continuously since it is still in BETA.

Then, if that does not help, can you then remove restricted drivers?

and then from https://help.ubuntu.com/community/Wi...river/bcm43xx:

Quote:
Step 4.

Under the desktop menu System > Administration > Hardware/Additional Drivers, the b43 drivers can be activated for use.

Note: A computer restart may be required before using the wifi card.

Interesting. Prior to seeing this, this morning I tried the Natty liveCD on a netbook that requires the STA driver. Worked fine straight from the liveCD (no wired connection).

The crappy GMA500 video still isn't supported, but there is a ppa that has a fix for that.

Must get around to an upgrade sometime.
