5G Radio does not broadcast SSID on autonomous 3602

[prado94@yahoo.com]

Hi,

My 3602 running 15.3.3JF12i will only broadcast on 802.11N over 2.4G only.  The config I have is:

dot11 ssid LM0701
band-select
authentication open
authentication key-management wpa version 2
guest-mode
wpa-psk ascii 7 xxx
-snip-

interface Dot11Radio0

Any help on this issue will be highly appreciated!!

Pls post output for below CLI commands. Does it got 11ac module plugged into it ?

sh ip int brief

sh controllers dot11Radio 1

HTH

Pls see the outputs from attached file.

Note I am seeing same problem on two separate 3602s - one with 802.11ac module and one without the 802.11ac module.

I have "wr erase" and use CLI to rebuild both of them from scratch.  However; the problem persists.  

Any help / pointer will be appreciated!

On first view it looks like it's running. Is this an I or E model, with internal or external antennas?

Did you try different test clients?

[prado94@yahoo.com]

Thank you -- I have since tweak "dot11 band-select parameters" and it has done the trick.

The 802.11ac interface seems to having same problem.  I can sure use some helps to troubleshoot.  Attached is output of "sh controllers dot11Radio 2".  Are there any debug commands that I can look into the 802.11ac radio??

Thank YOU again!

You are now using a DFS channel (52), instead of channel 48 before. Both should be visible for a normal client, if you are in the correct country.
Could you maybe attach the full boot up process of the AP? That might show some other possible errors. But in my opinion, 5 GHz was working before and is still working. Can you disable the 2.4 GHz radio to better test this?

[prado94@yahoo.com]

All of the Wi-Fi clients --  4 x iPhones (XR or newer) + 3 Lenovo (X1, T460 & T480 all running latest Intel WiFi driver) have no problem to connect to a 802.11ac AP (Netgear Night Hawk).

I did disable 802.11n 2.4G radio on the Cisco 3602 explicitly – most clients will connect 802.11n in 5G flawlessly.  Some (Lenovo X1 + T460) will require some “nudges” (disable / enable Wii few times) for them to connect in 5G – they are approx.. 20 Ft away from the Cisco 3602.

Attached is the log while 3602 boots up – note that I have changed from 153-3.JF12i to 153-3.JPK to see if the problems I have w/ 802.11N in 5G and 802.11AC are bugs.  So far, I do not see any different behaviors on those problems.

Can't detect an error in the boot up, that is good. The used software confuses me a little, officially this here would be the latest (and maybe final) software for your AP:
https://software.cisco.com/download/home/284006700/type/284180979/release/15.3.3-JF14i
Do you have any of these features enabled? https://www.cisco.com/c/en/us/td/docs/wireless/access_point/15-3-3/configuration/guide/cg15-3-3/cg15-3-3-chap12-wdsroam-rm.html<> You should not have any of those enabled or on default.
