Crashing

As it's been posted since months ago, client crashes frequently right after champion selection. This is the worst time to crash because game's already started and nobody will know why you were not in the game. I try hard to be non-toxic but this crash is just ruining it all. It's like remaining celibate for half your lifetime then getting raped repeatedly. I know it's an abysmal comparison but I cannot stress it any less. Luckily for me, I had the chance to switch to friend's hot spot to connect to the game. It worked. Later, I had the same problem on that hot spot but switching back somehow fixed it again. Right now, I have access to only one wifi and cannot connect to the game no matter what i try. I uninstalled avast (antivirus if anyone's never heard of it), I rebooted, I've gone through that procedure moving and renaming logitech files in rads solutions folder. None helped. It seems as if the ip address of internet itself has been blocked to the game. Almost one in every 4~5 games I get this problem. Only to particular games this occurs (to me at least) and having tried reconnecting until game ended several times, I confirmed unless you can change your wifi you cannot enter game. I'm not sure if Riot finally took our threads into consideration but having completely missed a few games today, I still have not been put on leaver buster penalties. That's fortunate but I feel bad for rest of the team and it doesn't change the fact that I'm wasting my time scribbling this on boards. Being stuck in a dormitory, all I hoped for Christmas break was to have some fun gaming and relaxing but obviously didn't happen. As much as I am looking forward to seeing Blood Moon Thresh skin go on sale, I hope this gets fixed ASAP.

-------------------------------------------------------------Edit---------------------------------------------------------------------- Also, it'd be nice if leaving game and being unable to connect or disconnected from game had different in-game announcements. One time power in my place completely went off for hours. Probably all district. It was right after somebody on our team screwed up real bad and fed enemy team. I'm pretty sure everyone thought I rage quit. Even if it doesn't change the fact that they had to play with one less person, it'd stress me less if somebody on my team disconnected and I was aware he did not quit on purpose.
