Still have problem, when the sun shines the power levels bounce up and down from + 9 to -3, and get loss of sync. Managed to book an engineer yesterday, very pleasant but wouldn't believe me or what other techs have said. Replaced my white hub 3.0 with a new black hub 3.0, and cable/isolator. But same problem again new IP address/ monitor. But unable to contact them again. the website which has replaced any intelligent life form doesn't even know that you can use Broadband by cable, I'm not using wifi...
"No network issue found
Good news, we didn't find any network issues. However, the problem may be with your in-home connection.
To help fix the issue, you can check the WiFi performance of all devices connected to the Hub."
Going to see what BT fibre offers I have available.
