Need some help with wireless

some games run through an internet browser like Internet Explorer, or Google Chrome. Try deleting all of your apps in your Chrome, your game might run through Chrome. to delete your apps go to the wrench in the top right corner of Chrome right under the red X. Then go down to options, and a new tab should open up, click on extensions. After that, click on the button that says remove. It should be at the end of the App. Do that for every app.

sometimes this may not be a software or network problem but it may be a hardware problem try checking the router antenna or if you are using wireless check the antenna on the wireless card/usb adapter and if using a ethernet cable change it to see if you have the same problem.

All my drivers are up to date :/

There are literally so many reasons that such a thing could happen that I really encourage you to try and narrow down the possible reasons. If you have two wireless devices check if this occurs on both devices and if it happens at the same time, in regular intervals, during any specific events etc. At the same time, if you can, compare wireless connectivity to wired connectivity. Most likely you're experience an extremely weak signal that gets lost every now and then so, if you can, use a diagnostics tool to check the strength of the connection. Most popular brands have their own utilities you can find on their respective websites.
