615's Disabling 2.4 or 5Ghz Radios when 6Ghz not enabled

  • 1.  615's Disabling 2.4 or 5Ghz Radios when 6Ghz not enabled

    Posted Apr 18, 2024 10:25 AM

    Hi, We have a lot of customers experiencing this issue since the last Aruba Central update a week or two back. None of our customers have utilised 6Ghz yet so we have no SSIDs with this enabled yet.

     Up until now, we have not had an issue with leaving the flexible Dual Band mode set to automatic on the AP-615's but now we do. Some APs seem to be dropping either the 2.4 or 5Ghz radios in favour of 6Ghz, even though this isn't enabled on any of the SSID's but this is effecting some of the older clients that are only 2.4Ghz compatible.

    Luckily, I have managed to utilise the API's to change the flexible dual band mode in bulk for a few of our customers to set them to 2.4 and 5 GHz but this is becoming a pain. Has anybody else experienced this issue and if so, any suggestions on resolving it? I have also logged a case with TAC.

    Thanks

    were the AP-615s running Instant firmware or AOS10?

    They're running AOS10

    I have since had an update from TAC. This is supposedly expected behaviour for AirMatch to push clients to use the 6GHz radio, even if you have no SSID's utilising 6GHz, therefore dropping the APs down to one useable radio. I have requested this be reported as a bug/issue.

    Thanks,

    Josh

    Hi Josh,

    Can you share the case number?

    thanks for sharing, I might be hitting this issue too.

    The customers that impacted by this, were anyone of them running 10.5.1.0 firmware? and with gateways too?

    Hi @ariyap,  They are all running 10.5.1 firmware but none with Gateways. TAC are now investigating further so I will update when I hear more. In the meantime, I have been using the API's to change the Flexible Dual Band mode to 2.4GHz and 5GHz across all affected customers.

    Hello,

    We are having similar isssues with our AP-615. Set to flexible dual band they don't seem to always use 2.4 and 5ghz. Sometimes the lights will only show 2.4 or sometimes the lights will show 6ghz only. Also, the lights do not seem to actually correlate to what radios are active in central > devices. We are running 10.5.0.1_88128 on most devices. We have tried the latest recommended FW (10.5.1.1_89665) on a few devices with the issue and it does not seem to help in any way.

    The latest I have on this is that it isn't a bug and they won't change the AirMatch as this is by design. So APs will keep steering clients to radios that aren't even enabled! TAC did send me some links for features I can vote for to be able to change the flexible dual band mode at a group level, however, the links are dead. Quite frustrating to be honest.

    Thanks for the reply. Has manually changing each radio from flexible dual band to 2.4/5ghz solved the issue? I have noticed some of our APs still do not broadcast the correct band even when it is set manually.

    I found NMS-I-3017 for this issue, which is an internal registration. Please ask you local Aruba SE to vote for you. Or create a new idea, which then can be voted on. A bit ugly that TAC pointed you to that internal idea without telling/realizing that.

    I have the exact same issue, we are in the middle of replacing our ExtremeNetworks WiFi with Aruba and the 615's where the ones recomended to us. I have also found that if i make a new WLAN that is only enabled on 2,4Ghz it simply does not work since the AP does not transmitt on the 2,4ghz band. The AP will only use the 5GhZ radio and shut down 2,4 and 6. How is this an intended feature from airmatch?

    Also do you  have any info about the API manually setting flexible dual band? I've for about 400 AP's that have this issue, so if i can do it in bulk on a group level that would be awsome.

    Hi Sigurd Myhre, what version are you running? If you're using the default "automatic" flex configuration, the behavior is that some of the radios are converted to 6 GHz. If there are no 6 GHz VAPs, the radio is disabled. You likely need to change the flex configuration from automatic to your desired configuration (which sounds like 2.4 + 5 GHz mode).

    Hi Sugurd,

    This is the same issue we have been having. What I now do is use the API to force the AP-615's Flexible Dual Band Mode to 2.4 and 5GHz. TAC recommended using wifidownunder.com which I have been doing.

    I do this by using the CSV workflows option and populating a CSV with all required details, this is also handy for setting installation modes and renaming the devices etc. all in one tool so it has actually saved us a lot of time in the long run.

    yes Central Automation Studio (CAS) is a valuable tool. 

    one way to quickly test it is by changing 1x AP in Central.
