HI, Let me first say I have been using Afterdawn as a tech reference site for ages but have only just registered, I am happy to be a member Anyway here is my question: I live in the UK and have cable TV in my bedroom I also have Broadband internet downstairs in another room for my PC, Both services are with virgin media. I have been online with my XBOX 360 by using the modem from my PC's connection (by obviously Unplugging it and using it upstairs by removing the wire from my STB and pluging it into the modem) This worked great for a while and I even used the 1 Month free Gold subscription. The connection using this method was flawless I just plugged everything in and signed in automatically. I decided to get set up properly and brought a 1ghz 2 way splitter, a coax cable and a cable modem (tiny blue NTL one) I tested out my old modem with the splitter and new wire and everything worked no problem. When my newly acquired modem arrived today, I hooked it up and get the bloody MTU failed problem........... ..DAMMIT Checked forums and poeple who have this problem don't use the exact set up as I have (splitting a TV signal and directly connecting to the modem) If this has been covered already and I have missed it, sorry for being a pain But please somebody help. I have not yet tried to clone a mac address I don't know if I have to contact virgin to register the hardware and what I will be charged If I do and of course What do I do any help will be rewarded with....well a thank you CHEERS!
