Query: The cover range is too SHORT!

On the ads it says the cover range for indoor use can reach 300 feet, but the ones (wireless router and wireless PC card both from Linksys) I bought they just could go less than 10 feet. The signal strength could never beyond 60% even the antennas were as close as 3 INCHES to the PC card. The tech suggested me to return them back. That's a quick solution.PS. After this incident, I bought a Lucent OriCONO wireless PC card and D-Link wireless router at similar price. Both work great and, regardless of upstair or basement, the signal keeps at 100% strength.
