Upgrading RAM & WiFi in the Dell XPS 15 (9550)
04 September 2017
After spending a reasonable amount of time running Linux on the Dell XPS 15 (9550), I can say that the only hardware I can't get to work reliably is the Bluetooth support. I've had partial success, but really this is something I just want to work when I need it. The solution is to change out the existing Broadcom card for a cheap Intel AC 8260 card (cost me AUD $40), after which I now have good WiFi and Bluetooth support. Provided you have the right hex tool, the Dell XPS is easy to open and upgrade.
