10th time this month game has removed me from an active game for no reason and not recconected

In fact this time I took a video, if only the boards allowed some option to post vids it shows it trying to reconnect for a minute(the message was up their for 5 mins) the video coudnt show it but at the time my internet was working perfectly, i was using my phone and it didn't experience any internet problems at the same exact time i was doing this, my phone was downloading a file this problem only affects LoL tried reinstalling and the fixer tool I think its a client problem or something riot pls fix ur game i should be compensated for your awful game
