My Device Failed to Detect the 6GHz Band of Wi-Fi 6E Routers

This Article Applies To Any Archer, Deco, or TP-Link Wi-Fi Devices Capable of Receiving a 6Ghz Signal

Wi-Fi 6E brings Wi-Fi 6 802.11ax into a brand-new frequency, the 6 GHz Wi-Fi band. 6 GHz band offers up to 1200Mhz of the fresh spectrum, indicating more available channels, higher transmission speed, and less latency in a network.  

While some users find that their phone or laptop cannot see the 6 GHz Wi-Fi network from the all-new 6 GHz router or Mesh Wi-Fi 6E system, this article will share some tips & tricks on how to fix network devices not detecting 6 GHz band Wi-Fi signal problems.

 

 

1. Ensure the Network Device Supports 6 GHz Wi-Fi

If you are using an Intel AX210/AX211 Wi-Fi Card and are experiencing less-than-expected speeds, Please Visit this Knowledge Base Article Below:

To use the 6 GHz Wi-Fi band, you will need both a router or access point and a network device that support Wi-Fi 6E (6 GHz), otherwise, the device can only see 2.4 GHz or 5 GHz.

For a list of a few devices that support 6Gz Networks Please Visit This Info Page:

PCs or Laptops must be equipped with a 6 GHz Wi-Fi card to see the 6 GHz Wi-Fi network. e.g. 6 GHz network adapters using Intel AX200/AX210 including the  TP-Link TXE75E 6 GHz PCI-E adapter.

 

Question:  Why Can Only Certain Devices Connect To or See the 6 GHz Network?

If several of your 6Ghz devices are successfully connected to the  6 GHz Wi-Fi network, but only certain 6E-compatible devices can't see 6 GHz Wi-Fi, this could be due to the device itself,  please reach out to the device manufacturer directly for further advice regarding the information below.

  • Confirm if the 6G device has supported 6 GHz in that region or area
  • Check if the Country and Software Version of the device has support for 6 GHz networks. 
  • For Windows Computers, the 6Ghz Frequency is only Supported on Windows 11, PCs running Windows 10 will not be able to see the 6 Ghz Network

Note: The 6Ghz frequency is only available in select areas for Samsung devices. Reach out to Samsung Support for the latest information regarding Wi-Fi 6E compatibility and your device.

 

2. Update the Driver of Your Wi-Fi Card or Phone

Given that the list of devices joining the Wi-Fi 6E List is continuously growing, it is not surprising that some smartphones or wifi adapters need to be updated to support the 6GHz frequency. To update your device's network capabilities, please follow the instructions below:

  • For Mobile Devices: Check your phone's settings and check if a system update is available for your device. These updates included the latest drivers and compatibilities for your device.
  • For PCs and Laptops : 
    • Identify what Model of Wi-Fi Card is Installed
    • Navigate to the Support Website for the Manufacturer of Your Wi-Fi Card
    • Download and Install the Latest Driver for Your Wi-fi Card
    • Update Your Windows System to the Latest Version

 

3. Put your network device closer to the Router or Access Point

The Wireless Signal and Quality of Higher Frequencies, such as those in the 6GHz Spectrum decrease much faster than older bands such as 5GHz. This means that the Wi-Fi provided through the 6E band is more susceptible to physical and electrical interferences caused by your environment. Try to place your client device closer to the router to see if your device can see the 6E network.

 

 

4.  Network Device Disabling 6GHz Frequency due to AP's Country Code

Some countries and areas have opened the Wi-Fi 6E Wi-Fi band while in some other areas, the Wi-Fi 6E frequency is still under consideration or not officially available to providers.  Here are some countries and areas that have opened Wifi6E for reference.

Some Wi-Fi cards may disable the 6 GHz frequency when it detects APs working in an area where Wi-Fi 6E is still under consideration.

For example:  When a Wi-Fi card detects that most surrounding APs work on NZ country code ( in New Zealand,  the Wi-F6E is still under consideration), it will turn off 6 GHz Wi-Fi frequency.

For this situation, it is recommended to reach out to the device manufacturer support to double confirm the network device supports 6 GHz in your area. 

 

 

[Case Sharing] Possible Fix for Intel Wi-Fi Cards: AX210/AX211

Note:  Intel Wi-Fi Cards may have Wi-Fi 6E limitations in some areas, thus it's better to reach Intel support first to confirm if the driver has supported 6GHz in your area.

If your computer is installed with network adapters using Intel Wi-Fi 6E AX210/AX211 (like TP-Link PCI-E adapter TXE75E), here are some other fixes (approved to be working by some of our customers) that might help:

  • Install the latest wireless intel driver for AX210 | AX211

  • Try the older driver of 22.45. X for your intel AX210

Here is a post from the Intel Community that shared the Older 22.45.1.1 Driver and The Method of Reinstalling the driver.

After Updating your Driver, Please Make Sure to Update your PC to the latest version of Windows.
