I live in a cottage with walls 1m thick. To allow our televisions and other devices to work we rely on the powerline extenders for both hard wired and WiFi boosting. However, every day between 10pm and 6.30am, 2 extenders lose their connection.

I have rebuilt the entire system (master reset, paired, synced, updated firmware), turned power saving mode off. 

My electrical system does cross 2 consumer units for the Shed (50m from the house) and 'Mum and Dad bed' and i understand that the system loses some intergrity there but why does it do it at the same time daily?

Thank you for any advice
