Cable Forum - View Single Post - 50M No Ranging Response received - T3 time-out

Over the last few weeks (months?), I've been having awful trouble with performance. Normally, I get 50Mbps without problem, but sometimes (and more frequently) it all goes to pot - massive packet loss.

In the cable modem logs, at the start of the problems:

No Ranging Response received - T3 time-out

Usually, it fixes itself after about half an hour. Sometimes it results in no connection at all, and a firewall reboot fixes it.

I've called VM about it in the past, and it's always seemed OK at the time. I don't know if it's a problem with my modem, the area (St Albans) or something else.

My wife wants me to jump ship to BT Infinity, but I'd rather have VM if it works... there's also the 100Mbps upgrade due soon - but that could make things better OR worse.

It's a VMNG300 mode. Signal levels all look pretty good.

Any suggestions?
