can you post stats from your router if hh6 then go to advanced settings then technical log admin
are you using the test socket with a filter to see if that helps by eliminating your internal wiring
try quiet line test dial 17070 option 2 should be quiet and best with corded phone
Try a quiet line test 17070 option 2, any noise report a line fault on 151 do not mention broadband. Best with corded phone.
My router has been reset since then ooops!
Next time it happens, likely tonight I’ll post the logs. Thanks again
