I first noticed this problem about a fortnight ago, and has been getting worse to this day.
Unless I physically reset my cable modem by removing the Power cable, waiting 30 secs and plugging it back into the modem, my internet speed will slowly crawl to a full stop. At first this used to happen once a day, then twice a day. Yesterday I formatted my hard drive and reinstalled Windows XP (Not in an attempt to fix the problem, was planning this). In the last hour I've had to reset the modem 4 times due to the internet connecting at speeds that makes dial up speed looks like a bar of wet soap being chucked down a greasy slope
I've come to a conclusion that Virgin is giving me the shaft, but I'd like a 2nd opinion before I consider canceling my service with them.
I have an NTL modem since I was with them before Virgin took over. I doubt this has anything to do with it, but its the only thing I can think of that would make this problem fixable at my end.

we had a similar problem with our Webstar modem. They came out and the engineer said it was to do with the recieve and transmit levels of the modem. There is a certain amount of tolerance in these levels before it effects your speed. Best to get them out to it. Its something one of their engineers can sort out onsite.

Thanks for your advice.
Its easier said the done though. I Remember back when It was NTL and I had to have an engineer come out, They do everything in their power to avoid sending one out. Not sure how I eventually got one.
Is their anyway to check/adjust these levels by myself?

In your browser address bar type the following 192.168.100.1 and press Enter. That will take you to the login page for your modem. Click Login and use the word 'root' (without the quotes) for both user name and password. From there you can look at the various settings and log files for the modem. You can't change anything but it might help you identify the problem.
If it helps in your comparison my modem shows a Signal to Noise Ratio (SNR) of 41.5dB downstream and a Receive power level of 6.8dBmV. Upstream is 42.5dBmV.

Thanks. I really don't know what to make of everything though. There are afew worrying events in my Event log that are very recent, such as: "Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 timeout" And "DHCP WARNING - Non-critical field invalid in response."
I don't know what any of these mean but I'm positive it's not 'thumbs-up, everythings fine'
Would posting the whole log shed any light?

I apologize for the double post.
Have read up about the information displayed on 192.168.100.1
My Downstream Receive Power Level: (-9.1 dBmV) is apparently way too high, and my Downstream SNR: (23.9 dB) is too low.
Is this true? Do I need to fetch out an engineer?

Yes to both questions. The SNR is particularly bad. That figure gives the Signal to Noise ratio so you are getting roughly 25% signal and 75% noise. You definitely need someone from VM to sort it out.

Am trying to get one out but as expected is proving to be a hassle. Each time I call I get someone who, is not only Indian but in India (how am I supposed to get someone local out if I'm talking to someone in India!?), and avoids my questions concerning an engineer by wasting time and hanging up due to "my time being up".
Will have to keep trying. Thanks for pointing me in the right direction greysts.
EDIT: If by both questions, you mean my log question; here:

Sorry, my two 'yeses' were to these two questions; Quote:
Is this true? Do I need to fetch out an engineer?
Have a look at this link. It gives some useful information about tracert and how to use it. Run a few yourself then click on the VisualRoute link at the bottom to get a graph of what happens when you run it. It would be interesting to see if there is a particular point in the VM network that is causing a problem.

Have called and said I was being optimistic. On their end my Downstream SNR was down to 13.5! They have booked someone to look at my server in the next 48 hours, and if the issue is still not resolved, I have been given a work number to call.
Thanks again for your help!
