Could someone take a look at these error codes for me?

Since I've had my phone line installed today my modem keeps losing sync!

My modem seems to keep losing sync, Im not sure if this has something to do with the NATIONAL OUTAGE on the status page on VM?

Here are some logs / stats:

Upstream issue, nothing to do with national outage.

Happens from time to time, and especially when using torrents or similar software that opens a number of connections and potentially uses high amounts of bandwidth. These seem to make the modem go a bit scatty.

I am having a slightly related issue, my cable modem has been very unreliable over the past week and I cannot work out what the problem is. My cable is fine during the day but come a time at night when I use my pc for online gaming my connection becomes intermittent with my modems ready light flashing in a constant pluse. The sync light is lit and send light appears to be trying ro send data but not receive any data back. The setup is fine during the day so I know the wiring isn't a problem, could this be a fault with my modem, problems with my line or simply Virgin just messing me about because I use my connection with high bursts? I run a game server business so my data transfer does spike at night although I try to do most my work at night outside the throttling hours.

Okay so its still happening and keeps disconnecting so I have booked ANOTHER engineer out, this is about the 3rd time now!

One thing I noticed is that the Correctable Codewords have increased alot over the past few hours is this cause for concern?

When I mentioned this to the engineer last time he didn't seem too concerned?

You said that you had another engineer booked so waiting for the results from that.

Had an engineer out, but all he did was check the levels and replace my 50 meg modem...

When I rang tech support they said I was losing a lot of packets from my modem which was causing my issues, how could replacing my modem help this? :(

Pretty standard for an engineer to do on the first instance.

Because if your modem were malfunctioning it could cause the packet loss you describe. It may not be of course, but it's perfectly feasible.
