Question Will this card fit in me Acer TC-885?

I really hate these prebuilt systems they don't document anything. So the card will physically fit I am pretty sure. The difference is the old card is a E only slot and ax210 is A and E. The ax210 should work in any slot that uses A or E.

What I don't know is what advantage using A or E has when it comes to wifi. Since your motherboard only likely supports the E connection it will ignore the A stuff.

Not sure someone that knows this hardware better than me might say I am wrong.
