Two weeks ago, I upgraded my home Swisscom Internet infrastructure to Swisscom TV 2.0 box and Swisscom Internet Box Plus.
While all Internet connections work like a charm (mobile devices, TV, desktops, Swisscom TV 2.0 box), I'm since this upgrade facing regular issues with my laptop to connect back to my corporate network through VPN while I never faced similar issues with the previous Swisscom Internet box and similar laptop/VPN client.
In a nutshell, everytime I'm trying to launch my VPN client connection - being connected through Wifi to Swisscom Internet Box Plus, either the connection gets immediately stuck and finally broke after two minutes or will broke after 20-30 minutes. After this, it is impossible to create a new VPN connection w/o restarting my laptop but for the same results than described just before. Note that while VPN connection fails, Internet connection works perfectly. Same problem if I physically connect my laptop to an Ethernet port of the Swisscom Internet Box Plus.
I checked around me and none of my colleagues customer of Swisscom Internet are facing similar issues. Some people told me that I might have to upgrade the firmware of the Swisscom Internet Box Plus but I'm wondering if my firmware is not already up-to-date.
Indeed, while Swisscom Site reports the following firmaware as latest ones.
