VPN keeps on dropping
I have a Win10 computer connected (via router) to the Xfinity modem. There are also other computers in the house, connected through ethernet or WiFi, as well as other devices (TV, etc.).
I need to use a VPN connection (L2TP/IPsec) to connect to my office and get access to resources there. I am having trouble with frequent drops of the VPN connection.
I have had days where the connection was stable for several hours, then dropped without any error message or entry in the computer event viewer, on other days it drops every few minutes. The IT people at work also tell me that there is no trace of why the VPN connection stopped. At one point, just before or after the connection stopped, my computer told me that it had detected a "network change".
It seems to me that the only place where a "network change" could occur is the Xfinity network. During all this time, though, my computer maintains connection to the internet. I have noticed, though, that occasionally I cannot open some webpages, the browser (Chrome) tells me that the site is not reachable. It usually takes a few seconds and then the site is reachable again. I am not sure if this is related to the VPN drops, but I guess if my computer cannot reach the office server for a few seconds, it drops the connection.
So what causes these connectin glitches? Does anybody have a similar experience?
