Beta Software EAP783_V1_1.1.92 Beta Firmware (Update on 23th May, 2025)
Further tests done with Beta Firmware v1_1.1.92.
1. Is there any error message when failed to connect? Better with some screenshots;
Error message shown in the IoT app is: Connection failed. Failed to load data, Let's try again. If this keeps happening, please try: 1. Switching your smart device off and then on. 2. Restart this app, and try again.

2. Is this happening only some fixed clients?
Only with IoT devices, all other PCs, laptops, mobile devices will connect (although they do use 5Ghz band, so cannot comment on 2.4Ghz band). However, there are at 5 different manufacturers which cannot connect only to this EAP783. They will happily connect to EAP690E HD.
3. Did you test these clients with an open 2.4G only SSID? Will the same thing happen?
Yes, I did try with open 2.4G SSID named TestIoT. Same thing happened, no connection with IoT devices.
4. Are other clients working as expected when using this firmware?
To be honest, no, I've set up an internal speed test server, and I am getting downloads and uploads speed of about 55 Mbps. With same cable, EAP690E HD does about 600 Mbps download and 450 Mbps upload. Cable is cat 5e, but will be replaced soonest.
5. Does this happen on both of the EAP783?
Yes, both devices behave in the same way, tested.
With firmware 1.0.14, same answers:
1. Does that mean, all wireless clients unable to connect to the EAP's SSID? including mobile phones and IoT clients?
No, only IoT devices cannot conect. Mobile phones work.
2. Can client connect to other EAP models?
Yes, to EAP245 v3.0 and EAP690E HD.
3. Does this happen on both of the EAP783?
Yes.
OC300 controller firmware is 1.29.7 Build 20250514 Rel.59723, version 5.15.24.20
Are there any other tests to be done, maybe with different methods or firmwares or analysis softwares?
Hi @liviu2004
Thanks for the info.
So both the firmwares have the concern.
Could you let me know when you installed the EAP783? Do you know if the IoT clients worked before? Or are they never connecting the EAP783 since the first installation?
Apart from set only 2.4 Ghz SSID, 20Mhz, channel 6, 802.11b/g/n, WPA2 Personal AES, Power High,
Please try: turn off roaming settings and the advanced settings for the IoT SSID.
Site settings:
SSID settings:
If the issue persists, please let us know the type and brand of the IoT devices you are using.
I have switched off Fast Roaming, and herewith the results:
Some of the IoT clients are connected.
Older Miele devices not, LED light controller not, sound speakers not.
LE: found LED light controller to be based on Boufallo Lab BL602 chip.
Hi @liviu2004
Thanks for the details.
Please test those client with the following SSID settings:
1. Band: 2.4G only;
2. Security: None;
Uncheck all the options under Multicast/Broadcast Management:
WiFi 7 products incorporate cutting-edge technologies, while some IoT devices still rely on relatively outdated technical standards. Certain compatibility issues between these new and legacy technologies are practically unavoidable. These problems are often particularly challenging to diagnose and resolve.
However, based on our extensive experience, the solutions we've recommended previously can effectively address the majority of such compatibility cases.
Thank you for your feedback here. Anything new comes up, don't hesitate to start a new thread.
