Troubleshooting What if my device failed to detect the 6 GHz Wi-Fi Band
6 GHz is a new frequency band ranging from 5.925 GHz to 7.125 GHz, allowing up to 1,200 MHz of additional spectrum. Unlike the existing bands on which channels are currently crammed into the limited spectrum, the 6 GHz band exists without overlap or interference. It is first introduced to Wi-Fi 6E, then to the latest Wi-Fi 7 Technology.
While some users find their phone or laptop is unable to detect or connect to the 6 GHz Wi-Fi network. 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 devices support 6 GHz Wi-Fi
To use the 6 GHz Wi-Fi band, both the router or access point and the network device need to support 6 GHz, otherwise, the device can only see 2.4 GHz or 5 GHz.
MacBook Pro (14-inch, 2023) or MacBook Pro (16-inch, 2023)
Mac Mini (2023)
Samsung Galaxy S21 Ultra & S22 Ultra & S23 Ultra; Galaxy Z Fold 3 & Galaxy Z Flip 3
Amazon Fire TV Cube
Note: The above list might not include all devices vendors or models that support 6 GHz and there will be more in the future. To make sure that the device is 6 GHz capable, it is recommended to refer to the official website of the end devices or contact the device vendor.
2. Confirm that 6 GHz has been enabled in the current area.
6 GHz has been adopted in some countries while in other areas, it is still under consideration or strictly prohibited.
Here are some countries that have opened 6 Ghz for reference.
3. Update Your Phone or Driver of your Wi-Fi card.
Given that more devices are newly supported Wi-Fi 6E, it's not surprising that some smartphones or computer Wi-Fi cards need an update to support the 6 GHz Wi-Fi band.
- For mobile devices: check if a software upgrade is required in order to enable 6 GHz.
- For PCs and Laptops: find the model of the Wi-Fi card, and go to the Wi-Fi card manufacturer's website to download and install the latest driver; If you are using Windows, make sure it has been updated to Windows 11.

Note: Intel Wi-Fi card may have 6 GHz limitations in some areas, thus it's better to reach Intel support first to confirm if the driver has supported 6 GHz 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:
Try the older driver of 22.45. X for your intel AX210
Here is a post from the Intel community that shared the older 188.8.131.52 driver and the method of reinstalling the driver.
4. Put your network device closer to the Router or Access Point
The wireless signals of higher frequencies decrease faster along the propagation paths, especially through obstacles. 6 GHz Wi-Fi band can be more susceptible to physical interference like walls. If your device cannot see 6 GHz Wi-Fi, locate the client device or router closer to each other and remove the obstructions between them.
