No Network Infrastructure and unable to add UPNP settings on router.

I think i found the problem ;o ?
Hamachi may be messing it up for me...
If I disable this:

My internet goes, can't get it back.

So i've just re-enabled it now to tell you about this.

So I uninstalled any driver there to do with hamachi / virtualbox.
Put in my motherboard CD and uninstalled my ethernet driver, then installed it.

My internet came back.

But still no router showing up in Network

Once the other computers were off, I turned off and on the router.

and what do you know .....

MY ROUTER IS SHOWN IN NETWORK

But how long until it disappears again, maybe rebooting it finalized some of this stuff I were doing ?

So i'm not sure what the fix was.....

I also rebooted my computer and a vpn program I had only just downloaded today told me it had discovered a new network and my internet was off, about 15seconds later my internet came on.
