Sure helps for newbs! Hmm, maybe ask your provider for a better internet speed, also mind that it will cost for money! And you can check some regedit tweaks videos they also help.
I wouldn't go with the regedit fix because one mistake could make your system unusable until u go buy a new computer or do a fill wipe on hard drive (or at least all your os's files)
U should probably get an Ethernet cable , no connection loss or a new internet Another way I heard is to just down wtfast some kinda app to make Ping lower in games
