Cable Forum - View Single Post - 50M Upstream congestion

I have had excellent performance on the 50 Mb/s business cable service with fixed IP subnet.

Speed tests usually run at around 48 Mb/s with very low jitter - 1-4 ms usually.

Last Friday there was a problem that caused the business Superhub to go offline - diagnosed as noise in the area , which cleared spontaneously within 30 mins.

Prior to this problem my upstream was locked onto Channel 2. Since the superhub reset on Friday it has gone to Channel 5 and performance is poor- around 6 Mb/s right now downstream.

I have just spoken to business faults. The engineer checked the port I am on - NMAL Cable 8/0/1 apparently. He said it was showing sustained 100% utilisation and has now logged it with the network team.

I asked if he could push me back onto Channel 2, but he said no he couldn't.

However I thought the idea was that if more than one upstream was available in an area then the Superhub would select the one with the lightest utilisation when it booted up? I have tried resetiing it multiple times but always it comes up on Ch 5 the congested one.

I might have misunderstood how this works though.... can anyone advise?
Perhaps it locks to the one with the lowest number of other users -which may not be the lightest loaded one of course.
