I use a BT Router - the 2wire BT700 HGV.
The wireless devices I have can see each other - eg a desktop connected with wireless can 'see' the iPad which is also connected wirelessly. Machines which are hard wired, however, cannot.
The same applies with, eg, ssh. I can access the command prompt from 1 machine with another using ssh if both machines are hard wired, however not if one is on the wiresll network.
I'm not great with networking - I only know the basics. I've hunted answers for hours multiple times over the past year with little success.
Any help would be greatly appreciated.
