I have a Netgear wgr614v6 router connected to my main computer, and a Roswill pci wireless adapter rnx g300e installed in my backup computer. When I had WinXp installed on both, I was able to connect my backup computer wirelessly to the router. I upgraded my main computer to Windows 7 Professiional, and Windows Home Premium on my backup computer. I recently decided to set the backup computer up permanently and tried to connect to the router. The wireless card shows up in device manager and is installed correctly. When I try to connect, the card can see the name of my main computer, but cannot access the internet. I made the router open, ie no security to see if anything changed, but it didn't. I'm not sure if I have to create a home network first or not, but since the backup computer cannot connect to the internet it won't have an ip address. I use Norton Internet Security 2010. Can anyone offer a solution? Thanks in advance.
