Smartzone 100 and R730 Reboots/ Offline Issue

Is anyone having issues with R730's randomly going Offline and requiring the AP to be rebooted in order to get it back online?  We have been seeing this issue for about 30 days now and support has been unable to tell us why the R730's are doing this.  The AP's are inaccessible most of the time when the issue happens, but sometimes we are able to still ping the AP and actually SSH to the login prompt, but the admin account/password will fail.  Once we power cycle the AP it works fine again.   When the issue is happening the AP is still accepting clients but it has no network access so those clients are broken.  It is very frustrating and Ruckus support has been no help.  The R730's are connected to Ruckus ICX 7650's via 5Gb multigig ports.  The switches report no problems and there are other AP's on the same switch at the time that have no issue, so the problem is just random Access Point specific.  The issue is completely random, no pattern can be found, other than support telling us they are seeing AP kernel panics and that they can't tell us why or how to make stop.   

Smartzone 100 version is 5.1.2.0.302 - which support had us upgrade to as they said that would fix the kernel panics - It has not

R730 version -  5.1.2.0.373

A few of the R730's have not been able to recover from this issue after a reboot and have had to be RMA'd.  Some of them will automatically reboot after 15-30 mins, but if we manually reboot them they typically come back online and work.  Was curious if any else is experiencing this issue with R730's, Smartzone 100's, and ICX 7650's?

We still have the issues.  They have tried several patch releases but now think the issue has something to do with the Qualcomm chipset used in the R730's and R750's.  We provided them new debug level outputs of the issues and hoping they find something from it and are able to come up with another patch for us to try.  It is absolutely ridiculous that this issue has been going on for almost 6 months with no end in sight.  After having almost zero problems with the R610's and R710's we have had nothing but issue after issues with the R730's and we told the R750's would have the same issues.  I would stay very far away from Ruckus R730's and R750's for anyone trying to decide between Ruckus and any other vendor.

Hi everyone,
I just heard some rumours that Ruckus is about to release SmartZone version 5.2 in these days and it should include firmware updates, especially accessing the WIFI 6 APs (even the not-certified R730 AP).

Anyone else into that?

We have been told the same about 5.2 being released very soon, however we do not believe it will have the fixes for the kernel panic hardware issues we are still experiencing on the R730's.  They also told us the same issue has been reported on the R750's.   Last info we have been provided indicated it is a problem with the Qualcomm chipset and we provided additonal custom debug script data to Ruckus in the hopes they can figure out the actual root of their problem.  If 5.2 somehow fixes all our issues I will definitely update this post accordingly.

I checked the release notes - it quietly says on page 36 "ER-7674 - Resolved an AP reboot issue on 11ax AP models". I dont want to be negative, but guess its referred to only one of the mentioned kernel panic issues.

If "ER-7665 - Resolved an issue where clients intermittently failed to pass any traffic when connected to 802.11ax (R750/R730)AP's" is helping, I really cannot say.

Furthermore the list of unsupported features on the R730 model is still very long! No Beamforming, no MU-MIMO in Downlink and Uplink, no OFDMA, no cell sizing, no 160 MHz channels, and many more others (which are not available for all other WiFi 6 AX AP, so I wont complain for them).

@Kevin, have you triple checked the power issues? https://forums.ruckuswireless.com/ruckuswireless/topics/high-drops-and-retries-on-r730

We using Cisco SG350X PoE+ switches - and of course all APs and the ports are set to provide at+ power. But its explicitly NOT UPoE or similar 60W standard on that ports.

Yes and it would be really sad if it was a power issue considering we have all our R730's connected to Ruckus ICX 7650-48ZP's.  The engineering team at Ruckus believes 5.2 will resolve some of our R730 issues but the kernel panics that appear to be a Qualcomm chipset issue it will not.   We provided new custom debug logs this week and hope they help them find the root cause of the issue.   We still have R730's randomly reboot and or hang and then reboot multiple times per day.  There is no pattern that can be located currently.

@Kevin: Do you have any update from our side regarding the R730?

The original 5.2 release was pulled as it was bricking some model AP's (supposedly not the R730) so we waited.  Ruckus provided us a custom 5.2.x build last week and do to scheduling we are looking at implementing on March 16, 2020.   I will update this post later next week but with everyone working remotely I am not sure we will experience all the same issues until we are back under full load.

There are rumours that much more WiFi 6 functionality incl. OFDMA and so on are coming with next minor SZ software release published after 5.2, so I guess something like 5.2.1 or so.

Keep fingers crossed.

Hey folks, did GA 5.2 resolved the kernel panic issue?
