I've noticed a huge change when switching from wifi connection to Ethernet, it's probably more than half the speed, i highly suggest switching to ethernet cable.

Most of the players if not all of them are using Ethernet cables, these help to get full speed from your router (of course if no one else is using the network).

You see this little thing called "NAT Type"? this cause lots of problems, Make sure that it says either "Open" or "Moderate", if it doesn't and says "Strict", You probably should change it, there are alot of guides on youtube that you can find on the NAT Type, i can make another guide on how to make it open.

PAY HUGE ATTENTION HERE!
This one might be the whole problem why you're having troubles finding a match, in some cases, i can't find a match lower than 150ms ping, and after i changed this one option, now i can find matches in ping lower than 100ms.

In windows 10/11, search "View network connections".


You should see this window popping up.



Look for your Network name, (As you see i put a black box on my network name, it should be there on the location of that black box). After this, press Right-Click on it and then properties.



You should see this menu popping up now, you might get confused seeing alot of things on it, don't worry we will focus on one and only one. As you see, I selected the one we've to do the DNS on, You just have to click on "Internet Protocol Version 4 (TCP/IPv4)" and then click "Properties", just like the image.



This menu will pop up now, Change the second section from "Obtain DNS server address automatically" to "Use the following DNS server addressess". Now just copy and paste these two into both of these:
8.8.8.8
8.8.4.4

Finally, Press "Ok" then "Ok" and exit Control panel, Congrats! you now can find matches with lower ping!

Please do not use VPNs, they will make your NAT Type Strict, you barely will find a match, Just follow the guide and this will make you find matches easier.

Do not forget to +rep
Thank you!
