My MacBook Pro started having connection issues at the end of last year. I presume a bug crawled into the vents. I don't think it is a software issue, since the computer has been factory reset by Apple recently after failing to boot, and the problem is still there. I was just wondering how much it would cost to repair/replace the WiFi card.
Thanks in advance.

Do you have AppleCare? If so, then you are under warranty and it shouldn't cost anything. If not, just ask Apple or an AASP.
You could also consider buying the part and fixing it yourself:
However, it would be worth getting a definite diagnosis before doing this. You could run Apple Diagnostics by starting up while holding down "D" or have Apple run a comprehensive hardware test for you. You could also try different networks and see if the problem persists in several different locations. If it doesn't, you could have something else going on like interference in your home or using a channel that too many of your neighbors are also using. If the problem is actually interference, then a new card won't help.
Good luck!
