Tags: #Wi-Fi 7 #MLO Network #iPhone 16 Pro
Model: EAP783  
Hardware Version: V1
Firmware Version: 1.0.10 Build 20231220 Rel. 40852

I have 4 EAP 783 controlled by a OC200, 3 are powered by a TP Link SX3206HPP v1.20, one is connected via mesh and uses a POE++ injector.  They have worked great, except I recently got my first MLO capable WiFi 7 devices in 2 new iPhone 16 Pros.

 

Whenever the iPhone 16 Pros connect to the EAP 783 with MLO enabled on the wireless network, it crashes.  Usually it's an immediate crash, but rarely I can get connected briefly and things work for 30-60 minutes, then another EAP crash. I'm thinking there may be some incompatibility or firmware bug and am hoping to find assistance or beta firmware.  

 

I was also suspicous of MLO just using more power and it being an issue, but the SX3206HPP can provide 60W per port and upto 200W total.  The switch reports 141W unused free power.  So I'm at a loss outside of a bad interaction with the new iPhone's WiFi 7 MLO support and a firmware bug.

Hi, we have made a beta version that fixed the issue. The official version will be released around the end of this month.

If you need that beta version, please don't hesitate to let us know.

So, further testing shows that this only happens if I have 2.4ghz enabled on the SSID that I enable MLO on.  The EAP783 is supposed to support MLO for 2.4ghz + 5ghz + 6ghz, but it seems I crash if I include 2.4ghz but am functional with only 5ghz and 6ghz (though needs longer term testing, but stable for at least a few hours now).

 

I would really like 2.4ghz included in my MLO SSID as there are some corners of the home and areas outside where 5ghz and 6ghz don't reach well and I'd rather not rely on the iPhone to switch SSIDs as it's unlikely to switch back to the MLO SSID later.  Definitely better if MLO includes all three and negotiation of which channels to use based on strength works properly.

  @jmccaskey did you end up finding a solution for this? (Other than deactivating the 2.4 band for MLO)

  @PavelF I haven't had a solution yet, but support has been engaged and they suggest this issue will be fixed with a new firmware update (they didn't have a beta to share yet) hopefully within the next month.

Will the beta be available via the controller interface soon or can I manually download it from somewhere?

Thanks.  I tried it out after the other troubleshooting on the other thread and something is bad with that .19 beta firmware.  Its something to do with the trunking option (I suspect) and spanning tree as I got a lot of STP topology change notices and then my LAN went down and I had to start rebooting stuff so I could get to a point where I could revert it.
