Intrigued, I looked at my PlusNet setup. It tells me I cannot go onto a home network and one suggestion is a conflict of firewalls.
This is curious - the no Home setup that is. I'm fairly sure it was set to Home, with the little house picture but now it shows a couple of monitors with Plusnet wirelessC2D4F9 between the PC and planet Earth. However, under the PC image it's got the same Plusnet icon with Home network included in the wording.
I am barred from seeing the 'Full Network' because of not being on a Home Network setting. Grrrrrr
