Sky sent me a new router/modem as I've been having some disconnect problems, I plugged it in and set it all up this morning but now my 360 doesn't connect automatically on boot up. It does eventually connect (when I select connect to Xbox Live) but it takes at least 3 to 4 minutes before it'll work.
As advised by Sky I've added Micro Filters to all my phone sockets, would this be cauing the problem or has anyone got any suggestions as to why the old one used to connect straight away, and the new one doesn't?
not really sure mate, try the avforums, loads of threads on there about stuff like this.
