Ruckus AP R720 No 5GHz radio signal

Question

Hello! I have had this r720 for a while, sitting in a corner. Originally I believe it was on zoneflex or SZ, Im unsure as I flashed it to Unleashed immediately.

The trouble I'm having is the 5GHz signals don't show up for any client or on the wifi analyzer apps I typically use.

Looking at this article (link below) it does say that the SZ could be flashed using a KSP er-6969. I have tried setting the channel width to 40MHz but that doesnt seem to change anything. I have tried Unleashed and the current solo AP firmware.

My question is, does flashing the latest SZ firmware apply the fix er-6969 or do I have to find a specific firmware with that fix listed?

I also see SZ patches in the list of FWs but I believe Id need a controller for that?

Thanks for the time!

Ok thanks!

1. i hard reset with the button

2. for some reason the 5.0GHz section doesnt show up in the table of option.

3. at the moment cant setup 5GHz at all?

Im guessing this device never worked and the previous guy had it on the shelf to do something with it later. Or figure out what was wrong with it.

I have a site with about 10 APs and a ZD1200 running 10.5.1.0 build 176 and after investigating some complaints found that in the ZD we had 6 of 10 APs showing no logs or graphs for the 5GHz radios, so clients were really reaching, in some cases to other floors to get a marginal connection.

It's an older site, so we're considering other vendors, I feel like Ruckus just has not ever really built up a good QA process for this stuff, instead relying on customers to spend their time troubleshooting for them.

Just posting in hopes that I'll get a notification for this thread if there's a fix one day.

Hello @aristotelis_cas ,

The Amber LED on 5 GHz means there is no client associated/connected to the 5GHz radio.

Refer to the below guide (page#12 for reference) : https://support.ruckuswireless.com/documents/2404-ruckus-indoor-ap-110-0-user-guide

Also, I noticed (from the above screenshot) the BSSID shows a all zeros (00:00:00:00:00:00).

I could suggest the following troubleshooting:

1. Hard reset the AP using a paper clip to factor default it. Press and hold the FD pinhole for 40 secs.

2. Create a Test SSID

3. Try to connect any client to the SSID.

Note: In case the client doesn't connect to 5GHz, then for testing, disable 2.4 GHz radio on the AP and try to connect to the AP on 5GHz to verify if the client is getting associated and the LED turns Green.

Feel free to revert for any further questions.
