Windows 7: Cannot Access Router With External Network Adapters

Cannot Access Router With External Network Adapters

I am running Windows 7 Home Premium (64 bit) on a Dell Inspiron 560. I am using a DI-524 D-Link wireless router. I have an Acer Aspire One Net Book running Windows XP Home it is equipped with an internal wireless network adapter. I can connect/communicate with router and access the internet with no problems whatever. However, when I connect an external wireless network adapter e.g. Alpha AWUS036H I cannot get a connection when I disable my internal network adapter. I have also tried the Trendnet TEW-424UB USB external wireless network adapter and the symptoms are exactly the same.

If I leave home and use another Wireless point of access I have no trouble connecting using the external adapters which means the problem is confined to my personal home network.

I have removed and reinstalled my router, and the network adapters drivers etc. I have uninstalled my Norton Firewall and and disabled my Windows firewall to no avail. I have removed my WEP security features and tried to run it open with no improvement. I have connected the external network adapters on a neighbours computer running XP to see if I could connect to my home network. That didn't work as well.

Bottom line is I simply cannot get an external wireless network adapter to work with my router. Yet my internal netbook adapter connects with no problems at all.

Any ideas?

You can try disabling ipv6 I am not familiar with that specific model router but ipv6 does cause strange issues with some equipment especially older stuff.

The following is a copy of my ipconfig file, as you can see only IPv4 is being used:
