I have a model B pi connected to an old router upstairs through ethernet cable. When I connect to this router with my laptop I can SSH and VNC to the pi no problem. When I then connect the pi to another network over WiFi using my usb adapter, the ethernet connection drops thus killing my VNC and SSH connections.
I am using Raspbian Wheezy and connecting with the basic WiFi tool from the desktop. I thought this would be something fairly easy to setup but I'm not really sure what to do next.
