http://ubuntuforums.org – I'm new-ish to Ubuntu. After an update yesterday, I have lost the ability to connect to the internet. Here is what I've got: Dell Inspiron 6400 with Ubuntu 12.04.1 After "lspci -nn":\ . . 03:00.0 Ethernet controller [0200]: Broadcom Corporation BCM4401-B0 100Base-TX [14e4:170c] (rev 02) . . 0b:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01) I've tried a few problem solving solution posted on this forum to no avail. I am stuck. Wireless never worked but Ethernet did. I would like to get both working. Any ideas? (Hardware)
