Why does the ping jump on the laptop when playing World of Tanks?

Hello, I have a laptop on Windows 10, moved to another apartment, the first 3 months all worked well, then suddenly for a short time ping began to jump to 300, while connecting by cable through the router such problems are not. Router reconfigured, finished the provider, changed to a new one – the story repeated, went and bought Keenetic Viva, connected to 5 GHz, the problem remained.

Called the laptop support (still under warranty), reinstalled the drivers, did not help, they said, bring it to the service. I don’t want to take it to the service, it will stay there for 40 days, they are unlikely to play tanks for 2 hours (it’s that it’s guaranteed to catch lags). What advice?

Answer

Hello. Not much concrete information on the problem.

Does the ping jump only when playing online games? Only in World of Tanks?
Do ping spikes appear after a long game? As soon as you start the game, is the ping normal?
If, for example, you play for a long time, close the game and immediately take measurements, is the ping normal? Or is it high?
Have you looked at the motherboard temperature (at the moment when the ping jumps up)?
Have you checked with other Wi-Fi networks (in other places)?

Apparently, the reason is not in the ISP or router. Everything works fine on cable, changing the router and switching to the 5 GHz band did not solve the problem. The reason is in the laptop itself, more precisely in the Wi-Fi module. I think that the Wi-Fi module heats up and the ping goes up. Or there is not enough performance of the Wi-Fi module. Recently there was a case when Wi-Fi problems started after the motherboard got very hot. That’s why I was asking if you looked at the motherboard (bridges) temperature. All this is supported by the fact that high ping problems appear after a certain time (if I understood correctly).

You could try disconnecting the built-in Wi-Fi module in the laptop and plug in an external USB adapter. At least for testing purposes. You can read the article wi-fi adapter for laptop. How to replace the built-in Wi-Fi module?

I don’t know if it will help, but try disabling the Bluetooth module in Device Manager.
