I have a Link sys wireless g router WRT45G. I can access it inside my home with another CPU but cannot access it outside from less than 75 ft away? Any suggestions? or is the router just too small for what I need. I need about 150ft range outside access. When the info on the router says 500ft range, does that include the wireless cards in the other pc's can access from 500 ft, or is it just the signal reaches 500ft??

Also can maybe a Direct TV signal interfere with this signal?
