Back to the basics... PING

Question

Ok...I have a default configuration on a Cisco 2620 with the FE port configured as IP address 10.10.10.1/24. I've connected my laptop with a x-over cable to the router eth port. My laptop is 10.10.10.2/24 and gateway 10.10.10.1/24. Why am I unable to ping the router from the PC and vice-versa? I've tried multiple cables, different routers and different PCs and I still can't get a ping. A show arp will resolve the PC as well. What am I missing here? Duplex/speed on both are set to auto.

Answer 1

Ok...I've doubled check everything and changed the IP scheme as well...not that it should matter. The link LEDs on the router are lit (Link, FDX, 100). Here is the config, sho int, sho arp and ping results.
