Can't connect to games for some reason??

I just came back from college for thanksgiving break, and with my new time, I decided to break out league again and play a little bit. The first game I get into, I never connect to; my percentage in the loading screen stays at 0% and I am unable to close out of the client using Alt+F4, Ctrl+Alt+Delete, Alt+tab, etc. At The only way out of this is to hard reset my computer, which gives the team i was unable to play with more than enough time to surrender the 4v5 in the first 5 minutes, giving me not only a loss (I decided to play ranked) but a low priority queue as well as putting me in a really shitty mood. I'm not sure if it's a problem on my end or on League's end. AT first, I thought this was jsut a fluke or whatever so I took the L and queued up for a normal game with my 20 minute LPQ. The exact same thing happens. I've troubleshooted my wifi, I've connected to multiple different wifi networks (I have a large-ish family so we have a few different wifi networks), I've tried restarting my router before games, I'm not sure what else to do. I've become very upset because this has happened numerous times since I got back from school and I've seriously considered just not playing league anymore after palying it for nearing on 7 years now as I am getting far more angry because of it than I should be (and it's a game so I don't think it's supposed to be as rage inducing as it is, and it's not even the gameplay itself that's pissing me off, it's that I can't even get the opportunity to play it at all.) Any help would be greatly appreciated.
