Lost Home network devices

Has BT Homehub messed up my Home Network.

before I had the Bt Infinity with the Homehub 4 installed I had a home network where my main PC and laptop could see and talk to each other.

Now my main PC cannot see the hard drive of my laptop; it can see its Media Device.

I now have something called "Network 2" Where has my "Network 1" gone; the one I used to connect my laptop with?

Any help please?

Rename 'Network 2' as 'Network 1'?

Check/Play around with 'Private/Public Network' and your File & Print Sharing settings.

Really a Windows query but change of router resulted in a new SSID and therefore Network. Presume this is all wireless.

Thank you
