@Jayach My speed guarantee is 250.
To indulge VF, I called the number on the SMS for the complaint I submitted and they carried out further speed tests and again said it was below the minimum guarantee.
The conversation actually started with, she had found a fault and would arrange an engineer and when I pressed her on it would not say what it was, and then decided to do speed test, two in fact and spent nearly 45 minutes in total on the phone. The Engineer was never booked and escalated to Level 3 support.
They are based in Egypt and have a fairly good grasp of English as a second conversation, I cant say the same for the technical skills though.
The speeds connected to the THG3000 some time are good as they are when I have the laptop connected to the switch but they don't last long.
The work laptop, when I was on FTTC connected at more or less synch speed so I don't think security is an issue, I don't have anything I know for certain is GB enabled to test it.
Another user had similar issues and I have asked them to reset the ONT as well as check and reset my profile in case something from FTTC time is interfering but they didn't listen or take it forward.
Could it be a routing issue? it can be occasionally good but then bad very quickly.
It is now back in the hands of 3rd level support.
As you can see from the above screenshots, the test to Youfiber servers was more than enough speeds for me and the MG but less than 30 minutes later, it had gone below 15MB and my network was no busier, if anything it was less traffic as I was the only one WFH. The most peculiar thing is the upload speeds are always stable, between 68 to 71MB on a line speed of 75.
