Confused about m.2 keys

[trents]

I'm looking into adding Wifi and BT to my desktop rig. It has an m.2 slot for a Wifi adapter and the socket has an E key but no A key. All the m.2 Wife adapters I see have both key A and key E. Will one of those work in my situation? Can't seem to find a clear answer to that on the net.

I dont think it physically fits. Get a key-e (only) card. They are out there.

I'd link you but amazon is being weird right now. Search 'ax210 cnvio key-e' (or ax211) which should turn up the results I see.

AX210 from the same (ED's) link is A or E. I bought this one for one of the motherboards over a year ago - https://a.co/d/iCR51Io
It's like "A or E" works with both. E only works with E. I have no idea why there are two different products. All these standards are confusing.
I see that WiFi 7 cards are E only, like here https://a.co/d/8Gcg7R5. Now we may wonder why motherboard manufacturers charge so much for WiFi7, and there is almost nothing else in the refreshed series. Most are using M.2 cards anyway, so it's all $20 difference on Amazon.

Okay, a card with A and E will fit either. I ordered one like that and it was compatible with my m.2 E key socket.
