One last thing I use microsoft edge but it also happens with google chrome that if I look at automatic ping host after a while without touching the mouse it logs out and even if I come back immediately automatic ping host has disappeared and also the connected server.
If I connect in DHCP with the TIM HUB PLUS + TECHNICOLOR and I do a ping benchmark it gives me lost packets (even if I think it's not true or it's a block of the TIM modem which manages PPPOE better). In fact, connecting a FRITZBOX 7590 TIM EDITION in DHCP 0% packet loss ping benchmark test (Lantiq chipset is more unstable in FTTC than TECHNICOLOR's Broadcom chipset and is unplayable online).
