You could try getting a wireless internet adapter for the comp & leaving the modem & router where they are. The adapters should be cheaper than paying for a tech to come out unless you have the insurance with your cable provider to cover certain things.
Very true. Not all routers can do that, though. He could get a Ubiquiti AirRouter for about $30 to $35 and set it up as a station to pick up the signal from the others.
To OP: If you get a Ubiquiti AirRouter, let me know and I can help you with the configuration for it. Or you could tell me what you need and I can configure one here and then send you the configuration. All you would need to do is upload it to the router.
