Hi @paulgills 

Thanks for posting and welcome back to the community.

Sorry for any issues experienced. All the levels are in spec. 

Please can you set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at https://www.thinkbroadband.com/broadband/monitoring/quality
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum 🙂

Best wishes,
