I have two network connections, one wired and one wireless. The wired network is a local only private network although the company domain is this side of the firewall. The WiFi is internet connected but requires authentication to get through the firewall. I can start browsing, pass the re-directed web authentication and get to the internet but the moment I plug the wired network in Firefox reverts to trying to communicate via this medium. Is there something I can do to stop this. Thanks
