iPhone/iPad Connectivity Issues with 5508 WLC's

pennwestenergy — Sun, 04 Jul 2021 05:25:06 GMT

Hello,

We are implementing a new corporate wireless network with Cisco 5508 WLC's and C3602I LWAP's. We are not running any RADIUS or EAP at the moment and are starting with WPA2 w/ AES with a pre-shared key to begin piloting.

The issue we are having is iOS based devices (iPhone/iPad) do not seem to want to connect. We just get a could not join wireless network messages. We have had success with several Windows based laptops, my MacBook connects, as well as several different Android devices.

Looking at the logs on the WLC I see these entries which correspond to the MAC address of my iPhone.

*apfMsConnTask_6: Jul 17 17:25:20.620: %APF-3-CHECK_SUPP_RATES_FAILED: apf_utils.c:376 Could not check supported rates. Missing Supported Rate. Length :0. Mobile MAC: 24:ab:81:92:4d:97.

Does anyone have any ideas or have run into this problem before?

Any help would greatly be appreciated.

Thanks!

Andrew

We have several deployments involving 5508 WLC but never encountered this problem.

May I ask, what model of APs you've got?

Can you check your data rates settings in 802.11a/n and 802.11b/g/n in your WLC and post it here?

Regards,

Dave

I too have many installs with no issues whith the iDevices. First off, can they join an open ssid you create? Then maybe try to create a new ssid with only WPA2/AES enabled with a simple pre-shared key and see if the devices connect.

Hi Dave,

We are running the Aironet C3602i Light Weight AP's. Here is our data rate settings:

Hi Scott,

Two of our SSID's are just WPA2/AES with PSK. We also have a guest network which is open and uses NCS for web based authentication. I will try and just create a fourth SSID that is open and see if I get connected. I will post the results back.

Thanks,

Andrew

Interesting... created an open SSID and still could not connect with the iPhone. Laptop connected and was good to go right away.

Enable Fast SSID Change if not enabled and try again.

Hi Scott,

That appears to be already enabled.

Thanks,

This is happening with multiple iDevices? Can you try to reboot one of those iDevices, because it seems to be an issue with the device and not the wireless.

Client load balancing is not enabled, correct?

Tried that with no luck. I am trying to track down a coworker who has an iPhone the same as mine.

We have client load balancing disabled but client band selection is enabled.

I would disable that for now and see. Again.... I have done many installs and always test with my iphone 4 or my iPad with no issues. Might have to take a look at your configuration.

Hi Scott,

It looks like it might be my phone

A co-worker was able to connect with an identical iPhone. Thanks for all your help.

I kind of figured that and thats why I usually test with various devices. Maybe power down your iphone and power it back up might fix it. One thing is to forget the network and manually add it back.

Try to enable all data rates. Just for a test. I'm testing iphone / ipad data rates at the moment and there seem to be some kind of bug in ios. If I enable 1Mbps (supported) it works

Re: iPhone/iPad Connectivity Issues with 5508 WLC's

Scott Fella — Wed, 28 Nov 2012 12:52:27 GMT

I have had no issues disabling everything below 11 and making 24mbps or higher mandatory and all others supported. This is with iOS 5 & 6 with iPhone and iPad.

We are having similar problems. We havea 5508 with about 25 3500 series APs. We have 3 wlans. 2 are wpa2 psk and 1 is wpa2 enterprise radius authd. The apple devices never have problems connecting to the wpa2 enterprise ssid, but reguarly have problems connecting to one or both of the wpa2 psk ssids. right now we i am sitting at my desk with my laptop and android phone cconnected to one of the wpa2 psk networks, but the ipad refuses to join. A coworker sitting next to me can't get his to join either, but can get any other non apple device to join.

The only log I can find that matches my ipad's mac says

*dot11a: Nov 28 09:21:35.574: %RRM-3-RRM_LOGMSG: rrmLrad.c:3702 RRM LOG: Client not found: E0:B9:BA:22:13:4D

I'm running the latest 7.2 code but thinking of switching to 7.3 to see if that helps. I'm going to go through and try some of the things suggested in this thread

Edit: I'm also seeing

*dot1xMsgTask: Nov 28 09:42:45.308: %DOT1X-3-MAX_EAPOL_KEY_RETRANS: 1x_ptsm.c:456 Max EAPOL-key M3 retransmissions exceeded for client e0:b9:ba:22:13:4d

I have had no issues with any of the 7.x code. What I know is that if I have issues with my iPad or iPhone with wireless, I would forget the network and enter it again. One thing also... is the pre-shared key... are you using any special characters or something that might be the cause?

Try creating an SSID with OPEN authentication.

What firmware is your WLC running?

What OS is your iPhone running?

Just want to clarify things, if your firmware is 7.0.X, and you have this problem(s), you (or your co-worker) is sitting STILL and not roaming around. Am I correct?
