Basically, more Pre RS Errors since Engineer visit....

[javedsaleem]

The signal had deteriorated as well so we have to reset more often.....

So you can't test by wire?

is one of your upstream channel power higher then the rest?

Hey @javedsaleem,

Thanks for the update, having checked in the systems we don't see anything showing as wrong, do the speeds and internet work fine for you?

You can also run some troubleshooting here or learn how to improve your WIFI here.

Hope to hear back soon, Joe

Hi

The last time Engineer came, he installed a 10db Attenuator.

I rest Hub 24hrs ago and below are readings. Is it acceptable to have so many Pre-RS Errors ?:-
