It is an old machine which has a BIOS whitelist and won't support many newer wifi cards. You can use USB options

Last week, for testing, I bought the following wifi card for my 11 years old machine

Unfortunately my machine uses different format, not M.2, physically won't fit therefore I went to the shop and swap to the following one (I did not have to pay more, they are same price):

And it works perfectly, get same result (download speed) with the 1G wired on same machine.
