well been on the phone with ntl support, they said it could be the onboard nic has been messed up somehow, as the cable modem was working correctly and had a lease of 24hrs for an ip, but the nic on the computer said 1hr lease but would drop out before the hour was up. Im currently trying my olde 3com 3c905b-tx nic i had in the spare computer i used to run this nic when i got the cable modem about 4or5 years ago. and it seems fine so far, 24hr lease showing etc.
They did say there was a problem in this area, but not my part.
update:- my connection isnt dropping out anymore and its running like a charm!!!
