Hi there i have 2 routers setup with the same ssid and the same security key but on different channels.

I use UltraVNC at home and i am having issues with my network setup

When i am connected to either router i can connect to any pc that is plugged into either router via ethernet cable using VNC and i can see them on my network

But to connect to a laptop that is wirelessly connected to either router i have problems and i also cant see them in the network
e.g

i am connected to router 1 wirelessly and another laptop is connected to router 2 wirelessly i cannot access it via VNC or see it in my network

When we are both connected to router 1 or router 2 then i can access it using vnc and see it in my network

i have the plug on my router going from the lan port on router 1 to the lan port on router2

what is the problem?
