LOSS in the game how to determine what the problem is?

Question

Computer networks

In the game, everything throws back, already shaking with anger. I called the provider, they reset the errors on the port ... and they say measure the speed ...
What should I do?
Are there any programs that I can find out what the problem is?

UPDATE:
The speed is 50 mb aside, it corresponds to the tariff.
router DIR-825ACG1
in the network several devices wire and Wifi, I am connected by wire

Answer 1

reset errors on the port

Call again if there are errors on the port again, then you have something with a network cable from the provider's equipment to your router. And resetting errors on the port does not fix anything, it's just a statistical info for the admin so that he can see where the problem is.

Answer 2

What game!?
Where you are in relation to the game servers (physical distance and number of intermediate network nodes), is checked using traceroute or mtr to the game server. router, or your provider's router)
To find out the game server, you need to either search the forums of this game or look at something like process explorer (Microsoft's sysinternals), it shows there what network connections the process has, there may be several connections, check everything
Very rarely, but as an experiment, why not try it, packet loss and lags can disappear if you connect via vpn (but not your provider and something closer to the location of the game server) ... formally the lag will become stronger, but the connection stability will remove frequent tilting back.
take it for granted, if the connection lags and your opponent does not, then you will lose to him only for this reason.
ps if the ping to the server is above 50ms, then you can forget about dynamic games like cs, you will lose to those who have 10 pings
, less dynamic games become unpleasant with pings above 100
in general, with 100+ms pings you can only play non-realtime games.
