Can you provide more details as to what you're trying to do? Are you looking to expand it etc ?

Craig BeckCommented:
Do you have APs linked to the WLC already?

What I'm dealing with is a very complex configuration on this WLAN controller that I was left to mange when we lost the other IT person.  I'm not familiar with this at all, currently we have 3 Cisco AIR-LAP1131AG-A-K9 deployed.  I'm afraid to  mess around with this to much as I don't want to crash the Wi-Fi for the building however, I'm sure that there are firmware updates needed on WLAN & AP's I've been placing Linksys WPA55AG around to boost Wi-Fi coverage.  What im trying to do is add Cisco AIR-LAP1121G-A-KP.  Also not sure if this is due to old firmware or just compatibility but for some reason newer Wi-Fi Cards will not connect to this Wi-Fi, even though the info is correct it will say it has wrong SSID or Passphrase.  Also on certain (Droid TURBO) smart phones it shows full strength when it attempts to connect is loses the signal. After the attempt to connect fails Full strength returns.

What version of code do you have on the controller?

Can you post the config from the controller?  At the CLI:

config paging disable
show run-config commands

Open in new window

Not sure how to obtain this info, do i need to use TFTP?

Craig BeckCommented:
No, just SSH to the WLC, log in and enter the commands, then copy and paste.

I've attached the config commands.

Craig BeckCommented:
When I said copy/paste I meant copy from the window and paste into a notepad.

I've managed to decipher the config, but there's nothing there to stop an AP connecting.  Are you connecting an AP to a new port on a switch?  I'd suggest you look at a switch where an AP connects and copy the port config to the port where the new AP is connected, then see what happens.

How many APs are already connected to the WLC?

That is what I did used putty to SSH into WLC, ran suggested commands, copied & pasted the output in notepad.

There are currently three AP's connected to this device, which should support up to five, the switches the AP's get plugged into are non configurable switches.  What about the firmware version, does this need to be updated?  How would i do this?  Did you notice anything to prevent connections from newer WiFi cards?

Thank You

Craig BeckCommented:
The WLC is a 2112 - it supports 12 APs.

If the APs are connected to an unmanaged switch you should be able to simply connect the AP to the switch and let it find the WLC.

What APs are you trying to connect?  Model number??

What version of code do you have on the WLC?

How would I find the version of code?
0
 
Craig BeckCommented:
Just log in to the GUI.  The version is on the first page you see.

It's also important to tell us what model your new APs are.

I've attached a screen shot of main page, the AP's I'm trying to add are Cisco AIR-LAP1121G-A-K9

Ok thanks.  What model are the current APs?  If you go to the Wireless tab you can see in there.

Craig BeckCommented:
Thanks.

Ok, I'd have a look at the console of one of the new APs while it's booting up.  That will show you where it's failing.

How can I provide you this ?

Craig BeckCommented:
Serial cable to AP.  Use PuTTY or another terminal emulator to see the output.  Log the session and upload it here.

ManieyaK_Citrix Systems / Network AdminAuthor Commented:
This AP doesn't have a serial port, you mean use putty to serial into Controller & watch AP boot>?

ManieyaK_Citrix Systems / Network AdminAuthor Commented:
Could you please provide more details on your last post?  Forgive my ignorance.
0
 
Craig BeckCommented:
Ah no... it's not your ignorance... it's my mistake!! I apologise!

You're right - The 1121 doesn't have a console port, just an Ethernet port.  All you can do is look at the CLI of the WLC while the AP is booting to see if you ever get a JOIN request from the AP.  If you use the following command...

debug capwap events enable
debug lwapp events enable

Open in new window


...you should be able to see the AP trying to join the WLC.  That should help you see why it doesn't.  If you can, log the console session to the WLC and post it here.

Other things to do are:

1] Look at the DHCP server to see if the AP gets an IP address.
2] Connect a laptop to the switchport where the AP connects to see if it gets an IP address from the DHCP server
3] Check that the DHCP server is using Option 60, and if so ensure that there is an option configured for the 1121 AP.

Again, apologies for the confusion :-)
