Hey guys,

In essence, I've been having problems with my Virgin 10MB Broadband for the past 3-4 months - random slowing of the internet at first, to in the past couple months the internet regularly randomly disconneting; either connecting again after a few minutes or needing to reboot the modem for it to work again. At first, the internet would only disconnect maybe once a day, now in the past few weeks - 1 month, it has been happening several times a day.

Reliability is a necessity for me since I work from home and after numerous phone calls to the terrible Virgin 'service' team who have given me a variety of wrong diagonostics from having a 'browser issue' to saying I have a faulty wireless router, hence sending a new D-Link router, but the problem still sadly reoccuring.

Around 4 years ago, we had a new Cable Modem installed (the Ambit E08C013 to replace the old NTL modem) and on the back where the Co-Ax cable plugs in, there is a 'Forward Path Attenuator' of 10dB. I have taken out this Attenuator, yet it still does the same occurance of the internet randomly disconneting happens.

I have data from the cable modem if this helps of the Downstream and Upstream status' if that helps?

Cable Modem Downstream
Downstream Lock : Locked
Downstream Channel Id : 6
Downstream Frequency : 402750000 Hz
Downstream Modulation : QAM256
Downstream Symbol Rate : 5360.537 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : 2.0 dBmV
Downstream SNR : 41.5 dB

Upstream Lock : Locked
Upstream Channel ID : 1
Upstream Frequency : 25800000 Hz
Upstream Modulation : QPSK
Upstream Symbol Rate : 2560 Ksym/sec
Upstream transmit Power Level : 43.0 dBmV
Upstream Mini-Slot Size : 2

There is also some confusing information in the Event Log about DHCP warnings of a Non critical field invalid in response?

Sorry if this has been a lengthy thread, but I am fed up of Customer Support not sorting out this issue, and want your help if it is actually the Cable Modem that is causing the problem - since I can't see anything else causing it!

Thanks!
