I am stuck with the current problem for days already and have no idea how to solve it.
To begin with, a few days ago I have started experiencing network connection problems with any online games, even though internet works on any other applications and devices. For example, in Steam client I can find any game servers I want, but as soon as I try to connect to them via games, my router cuts the internet connection specifically for my PC (other devices work properly).
I know this issue is not really related to TP-Link (as trying to solve the problem I have just bought a new router - Archer C6), but it didnt help.
The strange thing is that my PC easily pings any server from CMD via "/tracert" promt. And changing/resetting router also helps, but the next day problem reappears. I have tried tons of proposed solutions on different forums, but none helped.
If anyone knows anything about this issue, please leave the answers in the commnets.
