Guys tell me please, what can cut the speed? a problem with the usual drova.io service (cloud gaming), the connection in which takes place on the p2p principle directly without an intermediary. Recently, in the task manager, I see that the client speed does not rise higher (10 Mbps), and the Internet speed is 100 Mbps, in other services everything is OK, I don’t complain about the Internet and downloading. I contacted the provider, he replied that there were no restrictions on their part. I tried to play on 3 different laptops, the problem remains on all 3, and I tried it without a router - that is. directly

Answer 1
