I've got a laptop with an RTL8822BE (AC wave 1) in it that's driving me crazy.
I've just ordered a pair of AX201NGWs, one for a desktop, but realised after they shipped that they require a recent Intel chipset (CNVio interface), which won't work for me. These are available if anyone wants them, once they arrive, $20-ish. I'll refund if it turns out they don't work in your platform.
I'm hoping someone has a desktop motherboard that came with WiFi that I can grab the card out of for $15-30. E.g. 9260NGW, AX200NGW, AX201NGW. I'd probably be happy with non-Intel ones too. Or I can swap one in your laptop for something newer.
I'm in Wellington.
