Model: Archer C7  
Hardware Version: V5
Firmware Version: 1.1.0 build 20201120

Hi All, 

 

Yesterday I bought a new router Archer C7 (AC1750) as a replacement of N600 currently used.

Unfortunately after only 1 hour using 5GHz band stop working. There was a note: The 5GHz network is unavailable due to restrictions in your country/region.

The menu does not allow changing the region. Setup for 5GHz is a gray without possibility for change. After several reboots/factory settings and firmware update to last one the problem remain the same.

I bought the router only because of the improvements in the 5GHZ range and possibility to use it for 4K.
Any ideas how to solve the problem?

Hi, Is the Archer C7 a US version or an EU version? You can find it on its bottom sticker.

 

Are you able to change the 5G channel on the web interface? Please kindly show me the Wireless Settings page for the 5G network, you may cover the name and password when posting here.


BTW, when did you purchase the router, when did the issue start to happen? Try to reset the router to factory defaults, reconfigure it from scratch, then confirm if you can see the 5G signal again.

 

If none of these helps, it is suggested to contact the local tech support to check if they can suggest further or help with the replacement:

Where did this error message "The 5GHz network is unavailable due to restrictions in your country/region." show up? On the phone or computer? Please check if you can see this 5G network on other devices.

1. My router is EU version, self updated to last possible version of firmware visible on TP-link site.

2. As I wrote above - it is impossible to change something in 5G band - menu for both 5GHz networks (regular + guest) is a gray, unchangeable

3. 5Ghz band is not visible for any device with 5GHz possibility.

4. Error message is visible bellow settings for 5GHz band in web menu of router . Picture is attached.

Thank you very much for getting back quickly.

 

Can you please confirm again if the Smart Connect is on or not? Go to Advanced>>Wireless>>Wireless Settings page, try to disable the Smart Connect, then go to 5G settings, try to change the 5G channel to a different one, change the channel width to 40MHz, then reboot the router to confirm.

Hi again,

 

I confirm that "Smart connect" feature is off. It is impossible to set nothing in 5GHz band, all fields are gray without possibility to change it.

I cant perform those steps because of reasons above
