I installed a Linksys WRT54GX2-SRX200 in the lower floor of a large home. I am trying to connect to a Laptop that has a WPC54GX(SRX) PCMCIA card in it. The laptop is located 2 floors above the Wireless Router and about 50 feet away. I get very little signal to the laptop and most often no signal. I do not have a way to wire all the way to the Router but I do have a cable I can use in the room that the laptop is in that runs down to the lower level and ends in the telco room which is about 50 feet away from the router with one wall in the way. This is a CAT5 cable. Is there a way I can hook the laptop to this cable via the ethernet port and in the telco room plug into some kind of wireless adaptor that will talk to the wireless router?

Other thoughts were to buy a Linksys Range Extender and place it between somewhere to boost the signal and also put those High Gain Antenas on the Wireless Router.

Any suggestions would be appreciated.

Thanks
