Client Crashes at Champ Select

I continue to lose connection because Riot has a garbage client and refuses to acknowledge it, I have lost LP in over 30+ games and still Riot does nothing. My internet is 100+ mbps and my roommate doesn't have this problem. Tried re-downloading LoL client and still has the same problem. Doesn't matter if I'm connected to Wifi, ethernet or both.

My client loses connection causing me to miss my pick and get booted and when I'm in promos just hands me a loss plus a ban time. When the client crashes I can surf the web no problem, or turn off internet and back on and still have to wait for me to get booted before it tells me I was disconnected. Any one else have this issue?

Pissing me off because its unfair that I lose so many games because of this and Riot is just jacking off and ignoring this issue. Rant over until next time!
