My C1111-8P has a Modem connected to Wan0 (g0/0/0) and a local PC connected to Lan1 (g0/1/1). I have other routers connected to this modem, and the network access is normal. I don't understand why my PC can't access the network, nor can I ping the external network at the CLI end of the router. The following is my configuration and web screenshot.
