The dc and crashes are getting out of hand

I just lose a pvp match just cuz of that and lost rating. I was in queue, got the queue message, accept, loading map and bam. stuck in DC 3 times. restarted my router. got back and bam all my effort to go up in rank went down. this is ridiculous.i tried to join some W4 deimos, each time we started the game crashed on the start and when i even tried to get back i instantly crashed when entering the raid ike 2 days ago.
