If you can't do the Sveasoft thing to boost power, consider an
amplifier. I am no fan of Hawking products but the booster DOES work. I didn't use the itty bitty antenna that came with it however. I had a USR 5dB antenna that worked great. I was able to fill in all the coverage holes in the house and get enough signal out to the cabana to go wireless out there as well. Works FAR better than a repeater and isn't overly expensive.
