Interner was fine and has been since isstalation of hub

But the last two days it keeps saying that the hub isnt connected properly.. Nothing has moved or been changed or tampered with.

I switched itnoff last night til. This morning and it was fine all day until now again 10pm 

There seems to be no issues int he area etc

Hi there @Cwilson1985 

Thank you so much for your post and welcome back to the forums, it's great to have you here. 

I am so sorry to hear that you have faced these issues with your service, I have taken a look on our side and I cannot see anything that could be causing this issues. 

Can I ask how things are looking since your last post? 

[Cwilson1985]

I had the same issue yesterday had to switch off for a few hours, and its been working since, but no saying its not going to be fine forever
