So, as the topic states, I'm having an issue where my Battle.net sometimes crashes every 1 hour, kicking me out not only from WoW, but also from every other game as well, such as SWTOR, that's in no way related to Blizzard or Battle.net.
Eventually I tracked the problem down to a relationship between Battle.net and my PC's Standby mode. If I leave the computer for a while and place it on Standby mode while Battle.net is open, then after reactivating it, Battle.net keeps crashing exactly every 1 hour from the time of my return. If I come back at 20.45, I will DC at 21.45, 22.45, 23.45... and so on. The DC never lasts for long, just for a few seconds -- but it instantly kicks me from the game. And not just from WoW -- it also affects any other online game I happen to be playing. I also see all of my Battle.net friends going offline and back online after a couple of seconds.
It's definitely Battle.net related, because if I exit it before Standby, the DC's will never happen. My internet connection is otherwise extremely steady, fast and reliable, and fully wired with fiber optic cables. Once the problem occurs, the only way to fix it is to restart the computer.
Does anyone else have similar issues? I googled the issue and found topics about crashes at regular intervals involving Diablo, Herthstone and other stuff.
