So I have windows 10 on my machine now. I feel.... Less than human at the moment.
I need a new wireless card. On my wobo I don't have PCIe slots available. I have PCI though, and I can plop stuff on that. So, I need a PCI wireless card, N at least, to use in 10. I have a TP-Link WN751ND but W10 and 8 have a small kernel panic and explode internally whenever I try to use it. There aren't official drivers on the TPL site either though they are in 10 and 8. It still kernel panics though....
Even a thing for PCI that I put a laptop wifi card into would work great.
EDIT: Sorry, that may not be the best choice, as that adapter is for a full length mPCIe card. You can get WiFi cards in the full length format, or there are spacer brackets available to allow the use of a 1/2 mini card in a full length space.
EDIT2: I don't know what your budget looks like, but here's a nice full length mini card.
Now that you know what you're looking for, perhaps you can find an alternative. Lots of Chinese vendors advertise this sort of stuff on eBay. Give that a try.
If you had a modern desktop, you wouldn't be having issues finding a weird one off PCI card that works with windows 10 and linux.
If you do end up finding a card that works, its going to be at least 20 bucks. Worse yet, the only one that I have found that seems like it would work with win 10 is 75 bucks : (
