hi, ive recently bought a sony vaio cs-series in red. i have a few locations i use wi fi on and struggle getting connection because of the signal strength, all of the routers seem to be a little too far away. now boosting the signal on the router would be to much hasstle with there being about 5 different locations where i use wi fi, so i was wondering any ideas on something i could buy to boost my wi fi signal. also while im here on the right of the laptop just before the network cable port and the usb port there is a little plastic card i can pull out which i assume is for something else to go in, was just wondering what that something else was lol. thanks
jack
