I am trying to connect a computer in my grandma's house (next door) to our home network. All of the computers in our house are connected through a DSL modem with a built in router (Actiontec GT701-wg). (The computers in our house are connected to the modem via ethernet cables and a switch.) I installed an EDIMAX EW-7325IG IEEE 802.11b/g PCI Wireless LAN Card in the computer at my grandma's house. It detects the signal from the DSL modem, but the signal very weak and not strong enough to actually connect. Is there any way to boost the strength of the signal so that this computer can be connected to the network?
