Extra ActionTech V1000 Wireless Router

[wireless]

I've just recently up graded to Optik(tm) TV with its supposed high speed and wide range. I've got the new router and it's companion wireless unit downstairs and upstairs respectively. I park a travel Trailer in the yard that sits for most of the time, but it's nice to go "Yard" camping once in awhile if not towing out into the boons. Can I offer this ActiontecV1000 to the new routers as a client of theirs? Run a MAC address exception to offer it bandwidth at specific days and times protected with a long password (as its '50 out in the yard). Can this be successfully done instead of relying on weak (really weak) WiFi extender signals, and get a strong signal from what was a GREAT modem we used prior to the upgrade? Thoughts?
