Wifi Router

Hey, I wanted to get a new wireless router for my home, my budget is $100. I want one with range large enough to cover my entire house as my current wireless router, the basic linksys G router gives poor wifi in some areas of the house. Any advice on good routers, and good deals on them would be appreciated. I was also looking for a new wifi adapter for my second computer that is the primary user of the wifi connection, something that is obviously well compatible with the router I get, can either be usb or attach to the motherboard.

Two that currently have caught my eye were

and

Both those are good routers with the Asus one being a little better in my opinion.

This router is better, but a little more expensive

And you didn't specify for the card on your computer if you wanted a usb or internal. Here is a good pci express adapter. But get the drivers from the chipset manufactuer's website.
