Unstable Wi-Fi connection on new laptop?

I have a new laptop, but for some reason the Wi-Fi is very unstable. I noticed that when I gambled I often got fluctuations of up to 2000ms and I don't know why. It's been several days and the problem is still there. Can you help me?

Have you ever tried it with a cable… Ping is not only due to the WLAN…

Currently have no cable available

You always quickly make the Wi-Fi responsible for all faults.

have a look at the DSL statistics in the router

unrecoverable errors and such.

And keep an eye on the times when the faults occur

if possible use the 5 ghz Wi-Fi, which is less prone to interference

then check how many bars the connection has. And try different protocol options.

and use ping in the cmd shell, dr value is much more stable

not in the browser, it is too influenced by all sorts of stuff
