hi all. i've been looking around for a solution to a possible similar thing.
My smarthub has disconnected twice today follwing an engineer visit last week.
before the engineer we were getting 20 of the 35 we pay for, then after it was 44, so happy right?
after the hubs disconeected both times we've struggled to get 20 from it.
ran the diagnostics and its told me to reset the router which i did, turned it back on and low and behold we're back to over 40.
The connections only jsut started dropping out on the hub but after reading this i'm concerned this could go on for a while.
as its post disconnect that we're getting 20ish, could it be the hub being unable to cope with a disconnect?
all part of a longer process but i'm happy to provide the fault numbers etc if theyre needed.
You will need to test for noise using a phone, as noise on your line will cause dropouts.
Buy a cheap (less than £10) wired phone to run a check.
Then dial 17070 (free call) and select option 2, quiet line test, and see if there is any noise on the line.
It really should be quiet, so it could indicate ther is a bad connection somewhere.
Disconnections at the same time are normally caused by electrical interference.
You need to check it at the test socket, to make sure that the problem is not caused by your own wiring.
What does your master phone socket look like?
its the one on the bottom left. used that socket for the test
Did you remove the cover, and use the test socket behind it, by connecting a microfilter into it, to see if you still get the disconnections and noise on the phone?
Similar to this.
