slow wifi under 5M

Question

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:

please help:

Your home network has a few problems.

Checking Broadband Service

Checking Telephone Service

Checking Ethernet Connections

Checking WiFi Connections

If you still think something is wrong, please check the following:

1

The temperature of your Hub 5 is normal.

2

Your broadband connection is working.

3

Gateway IPv4 address is valid.

4

Your broadband connection is ready.

5

There may be devices in your wired network which might be limiting your in-home connectivity.

6

The device has low signal strength, please move it closer to Hub 5.

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! &nbsp;Do check that, even if it’s not your fault.
