Hey everyone, I have a wireless network and I need to set up a wireless router in order to get internet. The router is up-stairs and my brother's computer is downstairs and on the other side of the house. When I set up the router, which is a Linkys wireless-G Expander, I can connect to it but I do not have internet. It says that it has limited or no connectivity. Would I need to set up the Range Expander to the actual router up-stairs?
