thanks for using the forums to get this issue looked into with your broadband, I am sorry if its been causing you some frustration.
Usually what we would ask you to do is just follow these links in order to try and resolve it before we have a look- Slow Speeds Intermittent Connection
We may also ask you for a bit more information so we can understand your specific issue like have you checked your speed using our Speed test site here. We also sometimes ask customers to use a BMQ graph to gain more of an insight into your HUB's performance. We also may need to you reboot your HUB so that the data on the HUB's logs can reset, this helps the performance and also helps us identify any issues on our side.
Can I also ask what devices are experiencing slow speeds the most, WIFI or wired?
I have also had a look at your services on my side and can see no issues or faults on our side which is good 🙂
Please let me know how you get on with all of this information!
