I have just switched to the MAC and have a 15"Al PB. I have an Airport Base Station and am wondering if it is possible to plug in AC power connection on the AEBS and using the PB determine relative signal strength without first establishing my DSL connection.

I would like to avoid holes in the drywall where I have an obvious signal problem.

If this is possible what do I need to do on the PB and/or AEBS?
