This morning my connection was fine, then all of a sudden every time I tried to access a website, I was being redirected to the router website (192.168.0.1) with an error something like "Your internet connection is currently unavailable, try again in a couple minutes".

The router status on the router website says "PPP Server down" and the router shows 2 orange lights while the rest are green. I've tried pretty much everything and I'm still having this issue. :/
