Archer C9 V4 - 5GHz Problem - not available due to restrictions in your region

2019-12-17 16:43:22

Model: Archer C9

Hardware Version: V4

Firmware Version: 1.0.1

I have a Archer C9 V4 US:

My router had both 4GHz and 5GHz bands configured and working normally, but two months ago the 5GHz wifi stopped working.

I accessed the admin to review the configuration and realized that the 5GHz option was desable to check it. In Quick Setup mode, I select the correct region and the wifi screen displays the following message: "The 5GHz network setting is not available due to restrictions in your region / country." with 5GHz checkbox disable to check it.

I did restore it from factory and configure it again and the problem not solved.

Can someone help me?

@ErickSaraiva

Try to customize the wireless settings of 5GHz, including wireless channel and channel width.

And please ensure that the firmware of the router is up to date.

Still the same, it is suggested to contact the retailer or the local tech support to verify whether a replacement is qualified.

Good day.
