Bad internet connection

So my internet is working just fine, I can play any other games without internet issues, but when I start playing WoW, my spells are delayed, takes about half a minute to loot or take a quest. And it’s not a server issue since my friend is playing on the same server (Kazzak), is there any solution to fixing this?
