Internet disconnects while loading the LoL Client [READ]

Hey summoners, hope you're doing well.

As you can tell by the title, I'm having a bit of a problem. It started happening recently, whenever I try to load the League of Legends client, it takes forver. Along with that, I can't load or do anything else. While trying to search something on the internet, open steam, or anything else related, it seems like it just crashes everything.

Hope you can help! Mr Mirage

P.S. I have a pretty decent computer.
