My friend has Two Computers that are networked together. Well, His mom's computer Has the Cable Modem, Router and NIC Card all hooked it to that computer and has NO problem with the internet whatsoever. His computer which is about 40 feet away, Barely EVER has a DECENT internet conection. There is a phone in the middle of the two that he tried to unplugg but still nothing.. Sometimes it works sometimes it doesnt. He does have a really really old NIC card but I dont think that is it. His computer has the Wireless USB adapter that hooks in the USB. I have the same setup as him at my house and everything works find evben though both of my computers are next to the same room. What could be wrong here?
