When i go to connect to live, it fails and says the the MTU didnt go through, but it never did this before. Any Helpful Ideas?
Try doing a reset on the router, I know I had it happen to me once before and I ended up having to set the router back to factory defaults and then setting it up again and has been working fine since. Have you tried plugging it directly into the modem? If you have and it's working fine a reset of the router should hopefull fix the problem.
