Have got a noisey line since Virgin did some area work to "fix" local issues. Getting lots of SYNC Timing Synchronization failure - Loss of Sync errors in the hub network logs as well as T3 timeouts. Latency issues mean working from home is impossable.
Had an engingeer out due to lots of connection drop outs who reported the SNR issues to the Network Team but have heard nothing back regarding a repair. Same engineer told me our local area was over subscribed and the street cabinets were a mess.
One of my neighbours was told by a contractor the street cable needed replacing, no one seems to know what is going on. Can anyone help?

Line does not exhibit the obvious signs of an SNR issue.

Interesting, thanks.The dropouts are getting less frequent, I just wish Virgin would communicate with their customers so we know what's going on. That seems a strech when the different departments can't talk to each other though.

Hi mellatron,
Thank you for your post. I'm so sorry to hear you've been having a lot of trouble with your broadband recently.
Your BQM graph looks very good and stable, no sign of bad latency or packet loss, however looking at this end, a lot of your broadband downstream levels are out of spec, so I'll need to arrange for another engineer to take a look.
I'll pop over a private message now so I can help further.
