I have a bit of a strange problem that's been there for quite some time now, but I've only just recently began to become annoyed by it. On my icon tray, the network icon is displayed as if I have no connection what so ever. However, I can fully access the internet. I can't, however, connect to my homegroup and use the wireless printer in the house and other devices.
I have Google'd the absolute f**king shit out of this problem and tried countless methods to try and resolve it (updating drivers, editing the registry, resetting the router etc.), but to no avail.
Here's some pictures to clarify what I'm talking about:
As you can see here, it would appear that I have no wireless connection.

However, if I click on the icon, it actually shows I'm connected.

I tried going into the Network and Sharing Center to try and clear things up, but once again it tells me I'm not connected.

I'm really at a loss here... I don't know what the problem is. The signal between my laptop and the router downstairs is quite poor (something I'll soon be fixing) but if that was the issue, then how would I still be able to connect to the internet and browse at a very fast speed?
Any help or suggestions here would be greatly appreciated, as soon I may have to resort to reinstalling Windows... something I really really really don't want to do.
