Hi Sonny, thank you for getting in touch!
Having had a look on our systems there are no issues with signals coming from the exchange reaching your hub, there are no speed issues, and have been no disconnections in the past week or so.
From your most recent post you indicate you are primarily experiencing the issue on one device, via a wired connection. Do you have an alternative ethernet cable you can test with and see if the issue persists?
Let us know how you are getting on currently so we can continue to offer support!
All the best.
Molly
