I just changed to G1 (up to 1000M) in the past few days, and found that the network speed is often lower than 5M. Run the network diagnostic tool to check, and the display is as follows:

The preferred Downstream signal level is from -7 to 7 dBmV,    ( 0 dBmV is perfect )

The downstream signal levels for DOCSIS 3.0 fall as low as -7.7 dBmV ,  
and vastly too low for DOCSIS 3.1 at -20.4 dBmV.

An engineer will be required to resolve this - but it could be a fault at the street cabinet affecting several homes.

Do check for a known fault in your street via 0800 561 0061, this is an automated number.

They might say it’s your fault if the coax cable into the hub is not screwed in tight!  Do check that, even if it’s not your fault.

No - nothing has changed.  I don't think you have a WiFi issue.  Your downstream is performing poorly with a number of uncorrected errors recorded in the log.   May we also see your upstream stats?

What did the engineer actually have to say?

Seph - ( DEFROCKED - My advice is at your risk)

hi The engineer took out the original linker with the router. This is called the wideband equalizer. and said just need a plume pods for free then will be fine.
