Cisco AP not broadcasting SSID to Macs

Am having a very strange issue where we just purchased and setup two Cisco AIR-AP1141N access points that will not broadcast their SSID to any Apple device (MacBook, iPhone, iPad). The devices can manually enter in the SSID and connect, but it does not seem to be broadcasting correctly to a Mac. It broadcasts fine to all Windows machines.

SSID is set with the following:

Methods Accepted: Open Authentication
EAP Authentication Servers: Use Defaults
MAC Authentication Servers: Use Defaults
Key Management: Mandatory
Enable WPA
Enable Client MFP on this SSID
Advertise Extended Cabilities of this SSID
Advertise Wireless Provisioning Services (WPS) Support
Advertise this SSID as a Secondary Broadcast
Set Beacon Mode: Single BSSID

Cisco software version: 12.4(21a)JA1

Any thoughts?

Is there a setting for Short or Long Preamble? If so, set  it to LONG.

Strung, I don't see the Wireless Preamble option, as according to Cisco, the preamble is for 802.11b and 802.11g only, and this is an N device.

Sharee, is there any way to get that without having the Cisco Technical Support Services Agreement?

Shareef, when I uploaded the file you attached it is now producing a Red, Amber, and Green light pattern, and I can't login into it. So.... yeah.... that didn't seem to work.

Could have been on my end as a corrupt download... or something got messed up while flashing it. It totally happens.

The unit is an AIR-AP1141N, and so it only has one light on the front. It's flashing a sequence of lights (Red -> Yellow -> Green). It's been doing this for about 1.5 hours now.

I have a backup so I can reset to Factory Defaults if needed.

Are these the stand alone AP's or with a controller?

Using Putty to access it with the Green -> Red -> Amber lights, nothing is displaying.

So I decided to do a factory reset. Unfortunately when I tried to flash the new software again, it seems stuck uploading. It's been going on for 68 minutes now, where it says it should take only between 5 and 15 minutes. The only popup that is still working is the one counting the elapsed time. The other two show that the browser cannot display the webpage.

Now it is flashing green -> red -> amber again... :(

Do we know for sure that this firmware will work for the AIR-AP1141N (standalone AP)?

Thanks!

Shareef:

I found out what was causing the issue with the file you attached. It was a valid image, but we have an Autonomous Access Point, and that image was designed for a Lightweight Access Point. So the blinking lights were the device looking for a controller (that doesn't exist).

I definitely should have noted that the device is a Cisco AIR-AP1141N running in Autonomous mode.

According to the tech with Cisco, the correct IOS version to use is:

c1140-k9w7-tar.124-21a.JY.tar

You wouldn't happen to have that in a file somewhere, would you? Our Cisco Support Contract (for downloading) has expired.

So the firmware update finally worked, though it is still not broadcasting the SSID to Apple products (or Android phones) correctly.

Does it have something to do with the security settings? The encryption is set to:

WPA
Cipher - TKIP

Thanks.
