This is what I've been putting up with on my personal machine for months.

tl;dr: Suggestions for a wlan card/adapter for Debian9? My current RealTek wnic is barely functional, and my replacement (a TPLink... something) is completely incompatible.

I don't need anything super fancy, though I would ofc love support for AC/AD if at all possible.

I don't care (too much) about price, since I'm only going to buy one and very likely won't replace it for years.

------

I'm running Debian9 and have a have a RealTek card. Even when it's not arbitrarily dropping packets like in the screenie, it randomly caches them for up to 90 seconds and dumps them hilariously out of order. I can't play games like that. I can barely even browse devRant. Steam goes offline about once every 30 seconds, and therefore spams all of my friends with online/offline notifications. Streaming "works" on good days. Git works fine, however, so most days I don't notice the connection issues.

And yes, I'm using a community-patched driver (rtl8188ce) that's supposed to fix some of RealTek's more major screwups and increase the transmit power by ~20x. The driver helps, but only a little.

I've done some reasearch on wlan linux support, but haven't found anything very reassuring. Mostly just forum posts saying things like "Intel cards usually work fine!" I don't want to gamble. I just want to buy a card that will work and be done with it. :(

Suggestions? Insight?
