Working on a 2007 Latitude Dell D830 to give to a grandson. As Windows XP it worked ok. I wiped it and installed Mint 20.2 and everything works but wireless. It does not recognize my wireless router sitting on top of my desk 3 feet away nor any other wireless network in the area. Ethernet works. At one time I saw a message saying something like “a different wireless driver is installed instead”. Whatever it is, it ain’t working. I checked and cleaned the wireless card connections. Still nothing. If the card or connection was the problem, it wouldn’t have worked before installing Mint, but it did work. I’ve been using a newer (2013) Latitude dual booting with Mint 17 and that works fine. Is it possible the 2007 laptop is simply too old for any Linux wireless driver? Might installing the older Mint 17 work?
If I can get the wireless working, I’ll buy a smallish SSD drive, also a power cord, as I’m borrowing one from another laptop.
