My internet is very slow, the ping is extremely high to the point where some websites don't even connect. My mail won't load, yet some websites seem to work fine, but awfully slow. I tried hard resetting the router, I tried switching from 2ghz to 5ghz and still nothing. It's odd because I have an iPhone and a few other computers in the house that seem to be working perfectly fine. I have 100mbps internet and everything else is blazing fast. What could be the issue? Wireless Diagnostics indicate "Lan Connectivity Failure" You are connected to a network that cannot connect to your wireless router. Try resetting your wireless router.
