Wireless adapter cannot connect to my router

[beninpa]

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.

First, uninstall (don't disable) Norton Security and then reboot. It's hard to troubleshoot a driver or hardware problem when there is a third party firewall application installed. After that's done, try to connect to your router again. It that still doesn't work, check for drivers from the manufacturer. Sometimes Windows installs what it thinks is the correct driver, but turns out it isn't the one you need.

I tried uninstalling Norton. I actually went and bought a new pci card, but still have that same trouble of not being able to connect.

In order for a Win7 computer to access the internet, it must be set to Private Network in the Network and Sharing Center.

Unfortunetly that didn't work either.

beninpa,
it has to do with your wireless connection settings. In your main computer, go to command prompt, then type "ipconfig". Note down the default gateway ip and make sure you have that set as the default gateway in your backup computer. Also note down ip address of your main computer and give your backup computer an ip address in the same series (E.g. 192.168.....). If your main computer is set to receive ip dynamically from the router, then follow the same in your backup computer.

Hi:
When I try the IPCONFIG on the backupcompter, it doesn't have any address; I'm thinking because it cannot make a connection. I'm not sure where or if I can manually add the address.
