Strange problem with LAN

Hi,
Everynow and then i start getting this strange LAN problem and im abit puzzled as to what is causing it - see image:

It seems that it picks up 2 LAN networks and then i can connect to the internet. The only way i can resolve this problem is by disconnecting the LAN (when i disconnect one of the above both disappear) then enabling LAN again and it connect straight away.
Anyone have any ideas why i am having this problem?

This page should do the trick for you.

Unidentified Network appears every Windows 7 reboot and stops NW access

Hi Bill,
I read those posts and im still not very sure how to resolve this, im aware im deleting a default route (ROUTE DELETE 0.0.0.0) but i dont really understand why im doing this and what else to do after that ...

Apparently this guy who has the exact same problem as me came up with a solution by disabling an Apple service running:

I will try this to see if i still get the problem and over time i will post back. In the meantime if anyone can agree/disagree with me on what i just posted let me know.

Hi,
I do not have 2 LANS connected to my computer no. The other unknown network appears out of no where and this issue does not happen all the time it just seems random. If i disable the other LAN it also disables the other home LAN and therefor i have to go back into network connections and enable the LAN again for the internet to work(which also gets rid of the other LAN).

Run CMD as Administrator and type the following command.
"ROUTE DELETE 0.0.0.0" (without the quotes)

Open the "Network and Sharing Center". you can do this via control panel. Click on "Change Adapter Settings". Right click on your valid LAN, then click on properties. Then click on TCP/IPv4 and select properties.
Check "Obtain an IP address automatically" and "Obtain DNS server address automatically". (IF YOU GET YOUR IP DYNAMICALLY VIA DHCP)
Otherwise IF YOU MUST SPECIFY YOUR OWN IP ADDRESS
Choose an IP address for your "Local Area Connection"
Specify a network mask
Enter a default gateway IP address, this is the IP address of your Internet router
--------------------------------------------------------------------------------

The route delete command removes the default routes from all network interfaces so you have to reapply the necessary default routes to your interfaces.

But what if "Obtain an IP address automatically" and "Obtain DNS server address automatically" are already set by default, does this mean that i only have to run the delete route command?

No ive had to disable my wireless card temporarily since its incompatible with Windows 7 (driver issue). So the only thing connected is actually the 1 LAN wire.
