The problem wasn't present on all routers. Some times the router would completely stop not just slow down. Chrome casts were sending so many packets practically DDOSing the network from the inside. Google has had quite a few problems recently, and they just decided to make another phone pixel 2 as well as make their own chrome book. I have a pixel Gen 1 and the wifi in that is often unusable for videos, also had a microphone weld give out which they had said they fixed on all new models. Clearly not though. I hope Google finds their way once again, I haven't been a happy google supporter as of late. If their search results begin to be shitty thats the last straw.
