Daniele_UPC Hello Daniele,
Understood for the logs, and I did disconnected the TP-Link devices. so only my Pc connected in wifi or in ethernet and I do have still the same problem.
the last few day I did some test with an “Internet Connection Monitor” tool. Keep a Pc running 24h cwifi card disable and ethernet cable connected, and did the same again with wifi connected only. I did try with 2.4GHz and 5 GHz.
So in average I have 8 disconnection per day.
As I tried to explain several time to the different support person, the LAN is fine and there is nothing wrong with it ( See screenshot). The WAN is still not stable and get disconnected too many time per day.
So as explain, I’m a new customer so if UPC is not able to resolve this type of issue, please just let me know and I move to an other ISP.
