Random Disconnects and Now Random Crashes

Ive been playing since season 2 and up until the last 5-6 patches ive been able to play through matches without anything wrong apart from occastional lightning storms kicking out the internet. But as of 5-6 patches I now get random disconnects where the screen freezes up in game and says ive disconnected, but there is no drop in my internet as ive had streams or skype or videos that continue to work perfectly in the background. Can I get some clarification on what the heck im suppose to be doing about this because "disconnecting" up to a record of 8 times in 1 match and causing deaths isnt making climbing ladder that easy.
