My game gets stuck on the loading screen forever in of 1/2 games now.

hm that sounds like a connection problem

usually it takes about 1-2 mins for everyone to load into a match

if you are stuck on the loading screen you could risk closing league and getting back into the match (will often fix the issue)

a few things you may want to do on your end, just as a fix (or try and fix)

1. Make sure the connection between your pc/laptop and internet modem/router is wired. wireless might be convenient but it creates lag

2. Make sure you don't have too many, or any programs running outside of league. the game can draw a decent amount of your pc/laptop's stuff, so having extra things running outside of needed things (anti-virus protection/firewall) will cause lag

3. Your internet speed is where it needs to be. most online games now require around a 16Mbs connection to remain decently stable, if you have less than that; see about getting more speed. and the more connections you have in your home that are online, the more draw on your connection. (if you're in an internet heavy house, try to play when no one else, or few other people are online)

4. Your internet modem/router is up to date. often after about 3-5 years, your internet modem/router is out of date and tends to run slow; contact your isp to see about a new model. this usually won't cost you anything other than time

This has started to happen to me too two weeks ago. nothing about my computer or internet has changed. It seems to be on league of legends side, not my internet provider as my fiance connects fine and we live together.
