Have you created the vlan the port is in? -

I tried an 1841 router (FA0/0) attached to a 2960 (FA0/1) and it didn't work. FA0/1 on the 1841 would work. The 2960 did auto configure at half duplex, but hard coding it didn't fix the problem. And when I replaced the 2960 with a 2950, then FA0/0 on the 1841 worked.
With packet tracer, what doesn't work (that should) with one type of device may work with another device -- so try a different router or switch with the same configuration.
And the fall back option of any simulator -- save your work. Exit the software. Then reopen the software and reload your topology and/or configurations and see if it now magically works.:mike: Cisco Certifications -- Collect the Entire Set!
