When connected to the internet via wireless it runs really slow, for example, when I’m logged in to my Google drive account and try to access a folder it takes super long to load and that's if it does. It sometimes does it in other websites, But when I connect my laptop to my router via wired connection it runs fine and all folders on my Google drive account open up smoothly.
