my laptop like many other laptops has built with iEEE 802.11 card inside! is there anyway that i can tweak this card manualy so i can get stronger signals? i am tired of moving around with my laptop from kitchen to washroom to find better signal!! i have seen new external cards in bestbuy with Antenna! i wonder if those cards are any better than what i alredy have! i thought maybe i should ask this here before i waste $ without having the knowledge of that!
