Even with this new firmware, I am still having issues sending pictures over 5 GHz, and have to switch to the 2.4 GHz to send them. This is even after a factory reset of the device. 

Are there some settings I need to enable or change for the fix?

[FURRYe38]

Who is the ISP that your connected with? 

What channels are you using on the modem? 

Is Smart Connect enabled or disabled? 

Is AX mode enabled under basic wireless settings? 

Is MIMO enabled? 

Is IPv6 enabled or disabled?

The only progress is sadly the lack thereof. Enabling the Smart Connect gave the same photo sending issues on 5Ghz. I only have the option of enabling/disabling AX (not for separate bandwidths as suggested), and that did not fix the issue... and the DNS change also did nothing.

At this point, I workaround the issue and force my phone to connect to the 2.4Ghz and can send them smoothly.

Ok, let me see if I can get some more info on this. Thought this would have been fixed by now. 

What brand and model mobile phone are you using and what OS is loaded on it? 

[Clintonweb]

I am using an iPhone 15 Pro, running iOS 18.

Can you enable debug logging on the modems debug page in a browser at 192.168.1.1/debug.htm and then re-create the issue on 5Ghz with the phone, after it's created and seen, Select Save Logs on the debug page and let the browser save the .zip file to your PC. Then upload this .zip file to a cloud share service like onedrive or dropbox, etc. Then PM me the link to this .zip file. NG would like to take a look at this log file please.
