Keep getting ping spikes while using Wi-Fi.

Hi. Recently (since about a week), i have been getting regular ping spikes while playing the MOBA game ''League of legends''. Everyone 5-10 seconds or so my ms goes from a stable 30 to about 150. This issue does not only occur while playing League of Legends but also when playing other games. The spikes seem to always occur in important situations throughout the game.

I have done multiple Wi-Fi tests which have been extremely unstable as sometimes the test just doesn't work or some other times i get a result as high as 70mb/s for download and 50mb/s of upload. I have updated all of my drivers and have done multiple malware scans. I have also checked task manager while in a game to see if anything was using up Wi-Fi but nothing pops up.

I don't think the problem has to do with my router or internet provider since my my Wi-Fi works fine on every other system that is using it (Ipad, phone, other computers, consoles, etc...). I am not using Ethernet by the way, I am using a wireless adapter. The Wi-Fi worked alright before and I have no idea what caused it to suddenly stop working.

Please help .

Those pings could be from it checking your connection on your PC to their server. They could be having issues with their servers from everyone playing the online game.
