I have taken a good look at your service; it looks like you are in a busy area. There don't appear to be any major issues with the cable modem itself.

SNR's are good in your area. The only thing I could not check is your personal upstream utilisation (Every time I checked your PC was switched off).

I have run a ping test to your cable modem from the UBR, this shows no packet loss even with large packets,

All of your upstreams are fairly well balanced, you could be moved to a less contended upstream but the below would be true:

1) The UBR has load balancing enabled, so instructing a device to use an alternate upstream will be over ridden by the ubr telling the device to use the upstream with the least number of devices on.

2) I can seen no reasion for moving this device off upstream 2. Looking at the logs on Realise the upstreams are evenly utilised.
