Both phones were bought within the country and use the official china ROM

Thank you for your reply. I’m waiting to hear from you again.
To answer your first question:

There are a total of 16 channels available for 5 GHz 160 MHz: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128.

 

For 80 MHz, there are 24 channels in total: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128 , 131, 136, 140, 144, 149, 153, 157, 161.

All devices (both Redmi and Deco) were purchased in Myanmar.

 

Thank you for your clear explanation. I understand that this issue is not caused only by the Deco; it also relates to the phone’s wireless specifications, and possibly country-specific regulations. Our main purpose is to explain this to customers from our wireless perspective, so they understand that the problem is not solely due to our device, but also involves the phone side and local regulatory limitations.

 

Please let me know the root cause and the recommended solution, so we can explain the issue to our customers in a clear and technical way.BTW, I’ve gained so much new technical knowledge from you.

 

Best regards.

I appreciate you, The Redmi K80 is officially announced to support Wi-Fi 6E and Wi-Fi 7, so it is confusing that the phone does not detect the 160 MHz . I have also tested a Redmi Note 11 Pro, which only supports Wi-Fi 6, and it can see the 160 MHz on all channel without issue.

From the customer’s perspective, this raises questions: why does a Wi-Fi 7 supported phone fail to detect the 160 MHz SSID while an older Wi-Fi 6 device can?

We can clearly explain from the Deco BE65 side. However, mobile phone sellers usually have limited technical knowledge—they only sell the phones and cannot fully explain this behavior to the customer.

 

Best regards.
