Hey guys,
I recently had my equipment moved from one floor to another and these alerts have started popping up again, for the last week I can notice the connection hasn't been stable.
I'll attach the modem logs.
All levels seems fine (on installation engineer told me that the downstream levels should be between 0-3) but I still get these drops.
Any help is appreciated 🙂

Hi jaskeenee,
Thanks for your post and apologies to hear that you are having an issue with your connection since moving the Hub.
Checking the account, some of the signals are a little out. This may be causing the issues you are seeing. I would like to arrange for an engineer to come out to adjust things. This should hopefully fix the errors you are having. I just need to confirm the address to ensure we are booking the visit on the correct account.
I have sent you a private message regarding this. Just click on the little plum envelope at the top right hand side of the page to access your inbox.
Thanks,
