Using Cisco AIR-LAP1142N-A-K9 for home Wi-Fi

[stanleyd25]

Hello network and Cisco gurus, I have what is probably an easy one for most of you...

I was given a Cisco AIR-LAP1142N-A-K9 WAP and want to use it for my home Wi-Fi as my current router's signal range is pretty limited and doesn't cover my whole house. My setup is just an ARRIS SURFboard SB6121 cable modem and I would like to run the Cisco AIR-LAP1142N-A-K9 WAP off of that.

The only specific settings I want to user are maximized radio signal for max coverage, disabled SSID broadcast and MAC filtering for security.

This WAP was decomissioned during an office upgrade to newer WAPs, so it may have the office's old confg. on it. I really need help removing whatever config is on the WAP and then setting it up from there. I'm using Putty with a Console cable for configuring, but so far haven't even been able to gain access to enter commands. I'm attaching a screen shot of what I get when I console into the WAP with the ethernet cable connected from my cable modem to the WAP.

Thanks in advance for any help you guys might be able to provide.

If you have the correct autonomous IOS, you will need to convert the AP from controller-based IOS to autonomous IOS.

Hi David,

Leo is correct, first step you want to do is convert this AP to Autonomous. Probably talk to your Networks guys (as this image cannot be download without a valid service contract)  & see whether they can provide you autonomous image need for this ap (something like c1140-k9w7-tar.124-25d.JA.tar). You can refer these post as it gives some guidance of these conversion process.

Once you convert you need to put a simple config like below. If you do not want to broadcast SSID, then remove "guest mode" command under SSID config.

conf t
hostname <AP_HOSTNAME>
!
dot11 ssid <SSID_NAME>
   authentication open
   authentication key-management wpa version 2
   guest-mode
   wpa-psk ascii <SSID_PASSWORD>
!
interface Dot11Radio0
 encryption mode ciphers aes-ccm
 ssid <SSID_NAME>
 no shutdown
!
interface Dot11Radio1
 encryption mode ciphers aes-ccm
 ssid <SSID_NAME>
 no shutdown
!
interface BVI1
 ip address dhcp
!
end
write memory
!

Thanks for the valuable info. Rasika. Unfortunately I have no way to get this file as this was just given to me as a WAP that was no longer needed during an upgrade by my previous company. I'm sure they won't go to the trouble of requesting this file for me. So my next question is, if I were to purchase a router to come off of my Arris Surfboard modem, is there any way to use this WAP with it in the current controller based IOS rather than an autonomous IOS version? Thanks
