It might be because the wifi adapter is old.
I had an older laptop and got a cheap usb wifi adapter and it worked.
Maybe consider it as a last resort.
that is expensive for a wifi N based usb wifi chip (would only use this with a raspberry pi)
i would recommend this for a couple $ more: https://www.amazon.com/dp/B008I8A2PE
unless you have some high end wifi i would suggest you get this if the above is not good viable
there are lists for this ..

this is a common mention for like twelve bucks

you can also browse the kernel config to see what chipsets are available for use.
/usr/src/sys/amd64/conf/GENERIC
or better yet "make LINT" in that dir and then see what you have in HINTS ..but thats only if youre going to go so far as to build the kernel.

yikes almost sounds like a hardware issue at this point. I agree with Pain-Potatoes that you need to try and switch to an external USB wifi adapter. There's some simple ones around $10 if you don't need crazy range or speeds. Spend a little more if you need either of those. Here's my go-to cheap one:
Once you plug in a wifi adapter, go to control panel > network and sharing center > change adapter settings > then disable your old wifi adapter, then connect to wifi again using the new adapter. I'd give this a 99% chance of fixing the issue at this point.
