Had a issue on my 1 gig service which internet would just go off for no reason, only way to fix this would be turn off hub 4 at mains wait 1 minute and turn it back on.
This has been happening daily, anyway engineer came out said signals needed sorting as they was at -3 5 after changing something in the house internal white casing and changing the splitter to a new one the signals was around 7.
Anyway did a speedtest and now they was a issue with upload speed at 0.23 kbps both on wired and WiFi.
Engineer said their is nothing wrong with the signals however what ever he altered has not caused issues with the upload speed.
He decided to do a pin hole reset and set to factory setting the hub 4, and upload speed was back up to 49 to 50 meg.
Anyway 30 minutes later it's back down to 0.24 abd even 0.00 on some tests then goes back up to 49 meg and fluctuating all the time and very unstable.
In sure the upload before he altered things was 4 channels at 64 QAM it's now 4 channels on 16 QAM.
Customer service cannot get hold of the engineer to come back and now waiting for area manager as whatever has been altered has caused other issues.
