The simplest way is to just replace your current router with one that also has wireless.
To do it the way you want you want a access point. All this does is run wireless on one side and lan on the other. The strange thing is that the cheapest access points are routers running in bridge mode. So you can buy another router with wireless and hook it behind your current router. Still its easier to just run the wireless router as a router rather than messing with the bridge settings.
Does anyone know if I can purchase a wireless adaptor to plug into my existing home LAN?
My home is LAN wired in CAT 5 and I am wondering if there is a simple adaptor I can plug into my existing LAN router to enable a wireless connection for my laptop.
I don't want to move to all wireless for my home LAN. I just want to be able to use my laptop anywhere in the house when I am not using my desktop computer. I hope what I wrote above makes sense.
Does this product exist? Steve
