EAP 650/655 Wall dropping IP addresses of 2.4Ghz clients

Afternoon,
I'm experiencing issues with my 650/655 Wall units whereby where despite having MAC assigned IP addresses, a handful of unrelated devices using 2.4Ghz will seemingly drop their IP addresses but remained connected.
ER650 2.1.2 Build 20230221 Rel.41247
EAP 650-WALL 1.0.3 Build 20230407 Rel. 6521
EAP 655-WALL 1.0.0 Build 20230330 Rel. 14305
Omada software controller
Forcing the devices to reconnect does not renew the IP.
Only making changes to the radio settings i.e changing rail channel etc will allow the devices to renew IP.
Hi @dazmatic
Thanks for posting in our business forum.
Do you have an Android phone to scan your WIFI environment? I cannot rule out the possibility that your bad WIFI environment is causing this trouble.
2.4GHz is too crowded now. 5GHz is getting crowded. That's why now we have 6GHz band available.
And, have you monitored your device's signal strength? Is your device have a very good signal? Since the EAP is placed inside the wall, you probably get a bad signal reception. IoT stuff are also very sensitive to the signal because of the poor physical design or wireless chipset. They use 2.4GHz mostly for cost-saving purposes.
You can use your phone/laptop and place them in the same place where one of the IoT has the worst signal reception. Keep it stationary, use 2.4GHz and ping 8.8.8.8 -t and monitor if there is any drop.
Hi @dazmatic
Thanks for posting in our business forum.
Do you experience any issues with using these devices? Or do they work but missing IP addresses make you concerned about their status?
(I mean the client status of the controller is not a real-time update, it's periodic. There may be a lag but devices can still work)
So now we are trying to pinpoint who's causing the trouble. You have the Omada router. But I still hold the opinion that this could be a wireless issue.
Since you said this, let's try and do this:
Can you try rebooting the router alone? If you reboot the router and your devices can recover with IP addresses, then it could be a problem with the router. You probably need to refresh the page as well.
If you reboot the router and it does not change, you gotta reboot the EAP and make them connect again, then I still assume that's the wireless issue and especially with 2.4GHz interference and signal. Can you provide some screenshots of the signal level when it's connected? And 2.4GHz channel status? Like this, you see it when you click the EAP.
The devices stop working entirely - there's no IP address. Forcing them to reconnect means they'll associate with the AP but won't get an IP.
Rebooting the router does not help, only changing settings on the AP that ultimately force the radios to reset in the AP so either changing channel or rebooting the AP.
Only then will the devices reconnect and actually be assigned an IP address.
Looking at the logs however, I noticed that there's an issue with the AP and devices that are using WPA authentication
As suggested in another threat, I have increased the DTIM period to 3 for 2.4Ghz and everything came back online, however I suspect it was as a result of the changes to the AP radio settings.
I doubt it's fixed anything and believe this will happen again.
