Thanks for all of the tips.
I've used USB network adapters, but they aren't very well supported by Linux. They wind up being fine for SSH with mosh
, but they're quite bad for HTTP.
I wound up getting a 7260HMW BN
because it didn't say that it requires a Haswell processor. (The one that ktriebol linked says "4th generation Intel Core processors".) It probably requires a Haswell processor anyway, but I can hope.
It fits just fine and gets detected, but it turns out that this card's driver also has issues
. Until I fix that, I'm using a TP-LINK TL-WR710N, which I plan on turning into a ROOter
