I'm searching for reasonable fast USB wifi adapter hardware. I need an 802.11ac compatible device with dual-band support (2.4GHz band and 5 GHz band). MIMO support would be useful too. Do you know any such hardware with in-tree linux support or a stable driver at least?

I have seen and but I only found out that there should be chips by Broadcom (BCM43143, BCM43242 und BCM43566). I could not find any hardware with these. Any recommendations?

I've tried TP-Link Archer T2UH because the vendor claims Linux support, but I doubt the driver has been compiled for any 4.x linux kernel at all. It fails with a huge number of compile errors. I tried fixing them but finally gave up after some hours of sifting through broken code.

It looks like the general advice is to get a PCI-E adapter with good support (i.e. a non-staging driver, i.e. a driver in the main kernel tree). Most hardware shipped in Dell notebooks or Intel wifi hardware should meet these requirements.

I'm using an Intel 8265. It works well. It is fairly new, but more recent models are available.

Thanks for the hint, but I am searching for an USB device. I've added that info to my question.

I'm using an Intel AC 7260 now, which can be shipped with a PCI-E adapter for regular desktop PCs. After installing the firmware from Fedora's repos, it worked fine. Still, it is very old hardware and thus already end-of-life.
