Thanks for your post and sorry for the delay in response. We have been very busy and doing all we can to get to each community post ASAP.
Sorry to hear that you've been having issues with your broadband. I appreciate this would be frustrating. I've been able to locate your account and I can see that there are no issues with the hub at the moment, however there are some issues with the wireless connections.
I can see that some devices are too close/too far away to the hub. Have you tried rebooting the hub to ensure that all devices are on the best channel?
