Breaking things

The last thing I did before I left the parents was to set up the Slingbox. After working out I needed to change MAC addresses on the router, I eventually got the whole thing working well and then moved things around and wired them in. (Ethernet to the Slingbox, phoneline to the Tivo, all across 2 rooms, under carpets and around doors). Connected everything up again, when it promptly broke. Well, the browser internet connection did. I can access the Slingbox from New York no problem and get a great stream. My dad can’t access the web, even when the Slingbox is plugged out. So I’m no doing taking at back to basics and trying to fix it remotely. This could be a long week!
