Hi all

I am recently hav ing the same issues. My connection has been sound for the last 7 years, but suddenly as of last week, i started getting dropouts, mainly happening in the evening or when the PC is under immense networking pressure.

Engineer came round and from the data on the modem signal site, my upstream was at 59.5dBmv on a 255 NTL modem (live in the Herts area). We changed all the F's (used to install for NTL myself), the splitter i have and Isolater. He believes the CAB might be at fault, as it is putting out around 47-49dBmv and calculated a .9dBmv loss per 10 metres of cable. The cable trip from cab to my house is about 60m away.

I am running through a router and my NIC is outdated not to say the least.
I shall post my results in a later thread, i'm also going to bypass the router and run direct, and also check via my onboard NIC if the results are different. Finally to outrule any cable defectiveness, i shall run a patch lead from the Omni box outside straight to my router and see if i get varying results. The modem is only 4 months old and should not really present any issues.

With the changes made yesterday, my upstream level is around 53.5dBmv (after removing the splitter) now which SHOULD be ok, however, i was still getting dropouts last night and find it quite frustrating when gaming. Just to confirm, i also tested this with the modem on and PC off and still got dropouts in the evening.

The engineer reported a lot of modem faults lately and suspects either heat issues or a major networking issue affect either a MAC address range or certains CABS or proxy locations?

I'll keep you posted, but would like some feedback once i post results found from my modem.

Many thanks
