I was thinking of getting a wifi card like that, but can’t seem to find any.
I personally don’t recommend the ath9k cards. There are a handful of routers they do not work with. You’ll have to disable QoS to stop the packet drops.
that’s funny because my (wired) ISP router already has this problem, I can’t use ssh without setting IPQoS=0
ath9k supports N, so I’d consider it modern at least, since I think the vast majority of the population still use it.
N is not modern in any sense of the word. I think 6 is more used then you would think. All ISP I know are giving out 6 access points and have for awhile.
