|Thanks for your further input, Wanderer.... I will have a go with changing the firewalls - I didn't try that. The Windows 7 computers are both WIFI enabled and are in the same workgroup and homegroup on my network at my home/office and share files just fine - but remote desktop was a no-no at my first attempt. Since NetMeeting worked OK, I will probably use that facility, as it is free and I already have two old XP machines that I can use.|
At my son's place, (which is in Mozambique, by the way), they have 3-phase 240V mains electricity (at least some of the time) and a generator which is cranked into action when the lights go out! The main fusebox/distribution board is in the office next to the restaurant, and right now, (from here in UK), I don't know if their house is on the same phase or the same ring-main as the restaurant. If it is, or could be, then we could send the ethernet signal down the mains cable and decode it at the far end. Otherwise it will probably be wires as it is a bit far between the restaurant and the baby's room (about 50m) for wifi to reach.
I'll be going to visit him in a couple of months so want to have the solution to his problem tried and tested. They already bought a top-model baby intercom, but it doesn't have the range with a wall or two in the way.
