My WiFi stops working, or only works when I stand next to the unit. If I unplug it and let it cool down It seems to work for a few days. Can I open it and replace the airport unit? Thanks Bob the Blade

Yes - however there are many other reasons why you might have this problem. If this suddenly started and you’ve added wireless devices you might be having interference with too many broadcasting on the same band. Try changing bands or channels on the Time Capsule, or the new device. If this answer is acceptable please remember to return and mark it.
