Hi All

Sorry I havnt been about. The issue had disappeared and I've been busy.

However this afternoon its happened again. I am posting this with the ready light flashing on my modem!!!!

Signal levels appear fine :

Downstream SNR : 40.1 dB
Downstream Receive Power Level : 2.2 dBmV
Upstream transmit Power Level : 49.8 dBmV

Regards

Bongman

Some more on this :

This all seemed to start happening shortly after the UBR upgrade (?) recently. I was told that VM had upgraded the URB's to allow for 50mb and had moved all 20mb customers to these new/upgraded UBR's (I have no idea how true this is)

All I know is, shortly after the IP change a few months back, we (other 20mb users in Stevenage) have been experiencing problems we have never seen before (I have been a cable customer for about 10 years!)

1. Ready light flashes (like when there is a fault on the VM network) but sometimes you still have internet access
2. When ready light goes out completely, you lose all connectivity as expected. But when the modem later picks up a signal, re-syncs and reconnects. You have to perform a refresh/renew on the connected NIC (or reboot your router) to regain connectivity from/to your network. You never used to have to do this.

I think #2 is what azcomposer is referring to.
