- Installing Broadcom Wireless Drivers 42 answers
I'm preparing for a trip where I can't bring my desktop, so I recently broke out my trusty old laptop (Dell Latitude E4300) to get it ready for the trip. Previously, I had Ubuntu 12.04 LTS on the machine and there were no problems with wifi or the computer in general. My original problem came when I tried to upgrade to Ubuntu 14.04, which failed halfway through and long story short: I couldn't get it to work. I then installed Lubuntu 14.04 (It's a moderately old laptop and I had never tried Lubuntu, so why not) and it's going great, except, I can't connect to my wifi and since this will be my only method of access on my vacation, I really need to fix it. I'm kinda at a cross roads since I've never had this problem with this laptop. Any help would be great.
The output of "lspci -nvn | grep -i net" Says the wifi card is a "Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)"
I have looked at many other similar questions, but they're all very old and none have helped. Sorry if you guys get this a lot.
