AP doesnt find DHCP

Hi Steve.... well, i had everything all set and iu just had to fool with it. i had one ap set with a static ip and working fine, i had to move it b/c it wasnt reaching the offices it needed. once i plugged it in, i got the green/red/amber flashing lights, so it wasnt finding the wlc. i took it and connected to the console after several resets to default. problem is that i cant get in to global mode and none of my commands are being retained. can get in to exec mode, but when i type config t or configure it says invaklid command. i tried giving it a static ip and the controller name, but i dont know how to save config changes b/c there is no wr or copy run etc.... any idea how to best get this bad boy back up and connected? how do i get it back to factory defaults so i can just connect it to the network and config via gui like before?

Is it plugged into a different switchport now? The switchport configuration would be next place to look. The AP must have had a DHCP address, and it doesn't seem to be hitting the DHCP server. (Or it could be a DHCP Server issue, although that would present itself many other ways.)
Maybe plug in your laptop to the same wall port. It may ease the troubleshooting process.

is there a way to join the ap manually through the wlc?
Did you put in in a different VLAN ? Different subnet range?
There are a lot of things that you have to check. As Steve said, put your PC and see if you get an IP address.

what am i doing wrong?
You plug your laptop into the same port and you do receive a DHCP address.
No VLANs... So when the LWAP broadcasts it should hit the DHCP, that seems to be the case with your laptop, so what makes this LWAP any different. Was anything special setup in the DHCP server for this LWAP?
If we get the LWAP an IP address it should fix the problem out-right. Since it's not receiving an IP address their is only some many things it could be. Are you able to check the DHCP server to see if sees anything from the LWAP, or maybe do a SPAN session on the switch to capture the data to see what's really flowing.
I'm almost tempted to say switch the non-working AP with the working AP, but without knowing everything I'd hate to ask to bring down a working AP.

i am connected via console... i dont understand why i cant manually assign an ip.
this ap was working fine. all i did was physically move it from one location to another on the same floor. at that point, it had a static ip in both the WLC and on our dhcp server. i plugged it in and it flashed the green/red/amber lights which i guess means it cant find the wlc. thats when i took it up to my office and tried connecting via console to manually assign an ip or wipe it out and start over. i removed it from the wlc and our dhcp server. now, its flashing the green light and its unable to contact our dhcp server.
worst case i can go to our other location, take the power injector from the other AP and connect it to my laptop via the 10.0.0.1 and configure it that way.

The AP still doesn't get a DHCP address in a different location?
What console messages do you see while the AP is booting?

i wish i could reset to factory defaults or something, or manually set it to autonomous.
This has been quite deflating, i guess wireless isnt my thing.
(Any other console messages look out of place?)
I wouldn't let this get you down (especially on a Friday), and I wouldn't count yourself out of wireless. (after all we are still on the wire here the real fun in Wireless comes when you have to trouble shoot the WLAN
I found this for reverting LWAP back to Autonomous not sure if it's still relevant but might be worth a look at. (Since it's back from '05)

Steve, correct, its still in lwap mode, no ip. the only other message i get it that its assigning itself 10.0.0.1. then its the message i posted, over and over and over......i will try some things from that link.
Z,
I tried a few things, like holding the mode button while i plug the pwr in and the light turns blue, then to green.... i also held it in till it turned red. same result. Is there something else i can try?

The reason it wasn't working in your earlier with LWAPP is you did have the ap keyword after lwapp

also, how do i reslove this?
You should configure Domain and Name Server from controller CLI/GUI.
With an IP in the LWAP I would start pinging and see how far you can get. (trying to ping the WLC management IP, Default Gateway, neighboring switch)

I loaded up a spare LWAP changes the IP reloaded the AP and it kept the IP I put in.
Next thing would be to try and ping the LWAP from the WLC.

This might sound stupid but have we tried different cables? Were talking about getting a LWAP a DHCP address, I don't think it should be this complicated.
Does a sh run or sh logg display anything abnormal?
