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 Issue
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. If you can do the test on your hardwired PC/laptop and post a screenshot of your speed test result here it would be incredibly useful! We also might ask you 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.
Please follow these tips and steps for me and I will try to help further 🙂
