I have SBC Yahoo DSL and a wired router giving internet connection to my 2 computers. I have a 50-foot cord running under my carpet to the second computer but now that hardwood is being installed, that is going to be kind of a problem. So I'm going wireless. I'm getting the wireless modem through SBC so all I need now is a wireless adapter for my 2nd computer. This is where I get confused because a simple newegg search gave me about 300 options. What I need to know is what to buy for my 2nd comp. It can be through usb or internal because I have some PCI slots available. I just want to know what will be the cheapest thing to buy, but will still work at the same time.
