1.4.0 build 20241212 rel. 48194 breaks 160Mhz Channel width selection
1.4.0 build 20241212 rel. 48194 breaks 160Mhz Channel width selection

Had this firmware get pushed from the app. Expected some LONG awaited features and fixes but was instead disappointed to find out it has actually removed the ability to select 160Mhz Channel width and forced my 3 Deco X60's to use 80Mhz.
Please advise.

My Deco X60 is experiencing issues connecting to the 5 GHz network. I am located in Bangladesh, where mobile devices commonly operate on Band 4 (channels 149-165) within the 5 GHz frequency range. It appears that the current firmware on my Deco X60 does not support these higher channels.
The absence of Band 4 support is limiting the compatibility of my Deco X60 with local devices and hindering my ability to fully utilize the 5 GHz band. Furthermore, the lack of manual channel selection makes it difficult to troubleshoot and optimize the Wi-Fi network for the best performance in my specific environment. I understand that newer Deco models, such as the Wi-Fi 7 series, offer manual channel selection, highlighting the value and feasibility of this feature.
Therefore, I respectfully request that you consider developing and releasing a beta firmware update for the Deco X60 (Version 3, US model) that includes:
- Manual channel selection for both the 2.4 GHz and 5 GHz bands.
- Support for the 5 GHz Band 4 spectrum (channels 149-165) to ensure compatibility with devices commonly used in Bangladesh.
Enabling these features would significantly improve the functionality and compatibility of my Deco X60, allowing for better network optimization and seamless connectivity with my devices. I am confident that this update would be highly beneficial to other users in regions with similar 5 GHz band usage.

Thanks for all your help over the last year David, but I'm not interested in spending any more time troubleshooting this any further. I just ordered Unifi U7 XG access points from Ubiquiti to replace my X60's which I will either sell or donate. I hope TP Link gets serious about designing software and hardware that doesn't rely on the goodwill of customers to go back and forth testing beta firmware to fix what should be a simple bug. Otherwise, I think others will look elsewhere as I have.
All the best

Hi, have you tested the beta version I shared in the "Recommended Solution"?
Apart from Deco X50_V1, I think Deco X60 is the 2nd most updated WiFi 6 model, and I don't think it is EOL.
Thank you very much.
Best regards.

@David-TP My deco model is x5000, not x60. The provided "possible fix" beta files were for x60. (It also doesn't fix the issue on the x60)
It's now been 2 months since the issue was brought up, and about 6 months since the firmware was pushed.
This missing feature still hasn't been patched in.
Please provide me with the firmware for the previous update, before 1.4.0 Build 20241212 Rel. 48194. -
So I can manually install to restore 80/160mhz channel width selection functionality.
My device is 3x deco X5000 (US/1.6) (AX5000)
If those can't be provided, and there are no plans to fix this missing feature , I will be returning this back to Costco and getting another brands router. Losing features in an update is unacceptable. Although this should have never happened in the first place - this should have been an overnight ota fix, at the very least, once reported.
This kind of behavior for a $250 router is unheard of.

Hi, thank you very much for the feedback.
The beta firmware also works for Deco X5000(US)1.6.
I do hope you can try to manually install this version via the web UI first. If it didn't help, we had enough proof to push the engineer to release a new version.
Till now, I have received only one feedback on the beta version. I can positively say the beta version is not working at all.
After installing the beta firmware, you can send an email to support.forum@tp-link.com in case we need further help from the senior engineers.
(Please add forum ID #833844 in the subject.)
Thanks a lot for your understanding and support.
Best regards.
