Increasing the Tx level on the router may not even help your range much. If the router can't "hear" the PC, you're not going to have a reliable connection no matter how much power the router is pumping out.
One of the few spots where increased power has helped me is the install I did for a friend. They put up a business building on one side of their property and bought business-class from Comcast, while still having resi-class in their house. A pair of WRT-54GLs and some increased transmitter power later, they now have a stable WDS system spanning both buildings with the business-class service, allowing them to drop the resi-class in the house. Since there are 2 APs/routers, 1 in each building, client TX power isn't an issue and the increased router TX power means both WRTs have no issues talking to and hearing each other.
If the Earth were flat, cats would have pushed everything off of it by now.
