AFLM, Will your setup continue to work with no power? During last months power outages, cordless phone, or anything requiring power from the grid, stopped working.
The SLA battery in the Belkin UPS should be able to power the Router and Modem for about 5-6 hrs continuously. It would be relatively easy to rig up a 30W solar panel/Portable 40Ahr 12V SLA battery/charge controller and a programmable DC-DC power regulator, which is kept in the same room to power a Hi-Fi.

If this all fails then its time to go down the pub.
