How to troubleshoot network backend with Aerohive. Should clients be authenticating on the AP or the hivemanager cloud with a simple WPA2-PSK SSID?

I am going crazy trying to troubleshoot a problem we have at our site with Hivemanager cloud and about 20 AP250's..... it all started in our warehouse/production area and Intermec scan guns.

I have taken over the wireless since our network guy has not been replaced and what i have found out from our production/warehouse users is that the wireless never worked - constant dropouts and no roaming ever happening.

After some research i have found configurations perfect for our site. The result is that 3 out of 4 of our SSID clients have much faster connections and no roaming issues.

The SSID for our production scan guns is still having issues roaming. there are specific spots but i have found most the time, they seem to struggle with Authentication response time.

I'm trying to figure out where they authenticate from, the AP itself or the hivemanager cloud....

Radius is configured onsite so our corporate ssid works fine... i added our DNS server so the response is fine...but Gateway ARP and authentication seems to really take a long time.

Any suggestions would be great!

Thank you for that tech data, I'm seeing a 71% CRC failure on the wifi1 radio. That means 71% of the traffic processed by this AP is too damaged to read the first time and has to be resent at least once (likely more than once) before it's readable and the AP can move on to the next bit of traffic.

CRC failures are usually caused by environmental factors like metal, glass, or water. Would you be able to send a picture of the AP with as much of the surrounding area around the AP showing as possible so we can start to rule out any environmental factors that could be damaging your signal?

​Sorry for the delay....thank you.

Sam, you were helping me with a different AP before..... this is a different AP that I swapped in place of the other one that is having the same exact problems..... even if I turn down the transmission on both 2.4 and 5 to 2... it still does the same thing.... I found this morning that it had a UDP flooding message coming from some device connected to this AP on our guest ssid…. I figured I finally found the problem or something...but no.

we also configured a different port on the switch to use AND a different spot on the punch panel.... still same problems....

I even moved the AP to a different spot in the warehouse office... I was just thinking of simply putting that thing on a desk to see what that does instead of being in the ceiling.....

thanks for all your help.

We are a controlerless environment so the clients are connecting to the APs and not the HiveManager. With slow speeds and frequent disconnections, the most likely culprit is Radio Frequency Interference. If you could send me tech data from some problematic APs, I could let you know if you have any significant interference in your network and how to mitigate it if we do find interference. If you'd like to email the tech data to me directly, my email is communityhelp@aerohive.com.

These guides review how to get tech data, either through the HiveManager GUI or the APs CLI, whichever is easiest for you:
