I am brand new to Ubuntu and Linux though I've had some computer experience on other platforms some years back. I recently wiped Windows Vista off of an old Dell Inspiron Laptop that I don't use anymore and installed Ubuntu 14.04.3 Desktop (32-bit) on it. If I can get this running smoothly, I intend to convert my daily working laptop as well. The problem is that Ubuntu 14.04.3 LTS is not recognizing my wireless (it's a Broadcom 1390 that came with the old Dell.) I have seen multiple other questions posted about this and have tried the solutions suggested on about 10 of them but none have worked (some of the terminal commands return errors for out of date links, software no longer present in my version, etc.)
Some of the links did reference a script to gather networking information on the system so that others can advise me how to locate and install the correct device drivers for my mini-PCI wireless card. (Please note that I am posting this with the old laptop with a direct Ethernet cable to my router. I will soon need to switch to wifi, hence this request.) I will copy the contents of the wireless-info.txt here:
