If I go into an online game and want to play a round (LoL), Fortnite, Dota Auto Chess) crashes my internet (have no Lan cable use a Fritz w-lan stick) on my old pc was always good, but since then I can't do my new pc anymore.
ps After a few troubleshooting and reconnect it is usually, but then only with a high ping (200-400) which occurs again and again.
Reset your network. In the Windows settings under "Network and Internet / Network Reset" and then reinstall the WLan Stick.
Thank you! Seems to work again now… I could have come up with it myself.
