New downstream channel appeared with very odd power level

A new downstream channel has appeared with very high power level as below.

Doesn't seem to be bothering the superhub at all. Still running fine at 30 Mb.

I'm assuming it's in readiness for the 'double speed' update?

 

Anyone any thoughts?

Re: New downstream channel appeared with very odd power level

Hi piter,

 

My apologies for the issues you are having with your connection currently.

 

I have not been able to identify any fault in the tests I have run.

 

As you are in a different area and on a totally different UBR to the OP, could you please start your own thread and detailing the exact problems you have and including as much information as you can?

 

Let us know if you are using a wired or wireless connection, what time of day you have any issues. Include any speedtests, traceroutes & pingtests you have performed if they are relevant to your problem.

Kind Regards,

Jen_A

Re: New downstream channel appeared with very odd power level

Just for info.

The superhub did an auto reset this morning and all channels are

now within spec!

Weird, but I'm not complaining :smileyhappy:
