Hello, Having terrible trouble connecting to a wireless network after the re-installation of Ubuntu 10.04. I installed 11.04 but ran into a bios issue that prevented the USB connections from functioning properly. That's another thread.

At any rate, I can see the network, but cannot connect using the B43 driver. The STA driver does not even show the network. I have followed the steps in the comprehensive guide and nothing. Here's the critical information:

1. Make and Model: Dell Inspiron 1546

2. (lspci): Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
