Troubleshooting Cisco question

So I have this Cisco wireless AP that I'm trying to get up and running. I take the config from another AP that is working and upload it to my new AP (same model) and make minor changes, such as hostname and IP. Everything else stays the same. When I have my laptop connected to the AP directly with a 1 off IP address I can ping the AP, manage it, etc. Works good.

When I connect the AP to my Cisco switch it all falls apart. I can't ping the AP from the switch itself. Obviously my child-like Cisco IOS skills are failing me here, and I have no idea why I can't even establish basic communications to the AP. The switchport is up and I have connectivity lights.

Help me to learn!
 
Have you run #show ip interface brief? Merging in the new configuration may not have overridden the administrative shutdown on the ports. The switch and router's IP addresses are on the same network, right?
 
All good suggestions, thank you for the help. I believe my issue is bad documentation; right before I left today I double checked what ports the working APs were wired too and it looks like they were documented wrong, so I was copying settings from the wrong ports. I'm going to see if I can remote in yet this evening and give it another try, I'll post an update when I do!
 
And a trunking error it was! I had switchport trunk allowed vlans blah blah blah in there, but had switchport mode access instead of trunk. Thanks again all for helping me process through it!
 
Are you running multiple Vlans or do you need trunk mode even if there's only one? I was under the impression trunk mode just passed traffic from any vlan.

i think on most Aironet's (i don't work on APs much anymore) the dot11radio interface/s wont even come up unless you have a trunk on your Ethernet interface with a single subinterface. this applies even if you have a single SSID/vlan.
