Online Poker and boosting WiFi router

[newagedp]

NJ launched online poker a few weeks ago and you have to be in NJ to play.  To ensure you're in NJ, they use geo-location services through your WiFi.  Not only must you have WiFi but you must be within 3 additional WiFi connections.  I was able to play with no issues until my neighbors moved out this weekend, leaving me with only 2 WiFi connections.

I need to improve the range of my router so I can locate another WiFi network in the area.  This will allow me to continue playing online poker.  I have tried setting up a WiFi extender with no success.  How do I change the channel of my WiFi and attempt to locate more networks?  

Any assistance or ideas would be much appreciated!

This is limited by your PC, not the router. You can put a more senstive antenna on your PC if you have a desktop computer AND a wireless card with external connections, otherwise you're stuck up a creek by a poor website design, IMO (really GeoIP isn't that hard!).
