I've fixed it. I don't think, that installing newer version helped, since my old one 2.1.2 was working like a charm. More likely it was hardware problem. Network card, that was designated as LAN was prioritised on hardware level, so all traffic tried to go through LAN. I've just switched IP's on network cards and everything working just fine. To whoever might be looking for similar problem - check if your network adapters assigned right and their priority. Thanks to everyone for help.
