Disconnections of 2/3 minutes multiple times a day

[aleroot]

I have just switched from BT to EE Fibre and I have received a Smart Hub Plus router, now contrary to my old BT service I have started to experience multiple short(2/3 minutes) disconnections from the line every day.  Called the support, but couldn't really have an answer to the issue. 

Is anyone experiencing those disconnections ? One of the daily disconnection seems to be always at 14:00 ...

I also noticed that contrary to BT broadband where the IP address was changing after just a restart of the router, with the EE Broadband I can see my IP address changing every day...

The cable is connected to the ADSL filter, then to the only socket. 

The line always worked fine until Wednesday when I switched from BT to EE and replaced the router. I had to return the BT router, so I don't have it anymore.

@aleroot Did you use the original ADSL filter with the BT router and its cable, or new one supplied with the EE router in its box? No phone connected, just trying to pin down were the possible issue is!

I have tried with both...

@aleroot It is a real pity you returned the BT router so quick, there is a 60 day return time, with having tried cable swap's, adsl filter swap's then you are just down to the EE Router or a bad/noisy incoming line, and with the factor of the older style socket, can you take picture and post if you do not mind.
