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.

    don't your networks share same address space?

    Please dont thank in the question. Use upvote to thank. I think you have a power supply issue. Once the Wifi start to connect it causes a brown out and cuts out the ethernet. You can have as many network connections as you like/need. You just more power "Scotty"!

  • It seems it must be a power issue, have tried booting and letting wifi connect and then plugging ethernet in. Both connect and the connections last for about a minute or 2 but then wifi drops and wpa_supplicant fails to see the device anymore. I then have to bring the IF up again but that then drops the ethernet once more. I have ordered a powered hub so will see if that makes any difference.

It looks as if you are not supplying enough power to the WiFi device. You need to either get a device that consumes less power, or use a powered USB hub instead.
