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 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 was first introduced to Wi-Fi 6E, and then to the latest Wi-Fi 7 Technology.
Some users might 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.
Below are some common wireless devices that support 6 GHz radio:
| TP-Link |
|
| Other Brands |
Intel AX210/AX211/AX411 QCNFA765
iPhone15 Pro/Pro Max MacBook Pro (14-inch, 2023) or MacBook Pro (16-inch, 2023) Mac Mini (2023) More Apple devices are getting support 6 GHz band, visit this link for details: https://support.apple.com/en-us/102285.
Samsung Galaxy S21 Ultra & S22 Ultra & S23 Ultra; Galaxy Z Fold 3 & Galaxy Z Flip 3 FireTV Cube Oculus Quest3 Oppo Find X5 Pro
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:

Here is a post from the Intel community that shared the older 22.45.1.1 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.

Hey @Solla-topee
If your device is failing to detect the 6 GHz Wi-Fi band, there are a few factors to consider:
-
Device Compatibility: First, ensure that your device is compatible with the 6 GHz Wi-Fi band, commonly known as Wi-Fi 6E. Not all devices, even if they support Wi-Fi 6, are capable of connecting to this newer frequency.
-
Router Configuration: Verify that your router is broadcasting the 6 GHz band. This might require enabling the band in your router’s settings. Check the router's firmware as well, as an update may be necessary to properly support 6 GHz.
-
Interference and Range: The 6 GHz band has a shorter range compared to 2.4 GHz and 5 GHz bands and may be more sensitive to obstacles. Ensure you're within range and that the signal isn’t blocked by walls or other obstructions.
-
Driver and Firmware Updates: Ensure that your device’s drivers are up-to-date. Manufacturers often release updates that improve connectivity and support for new technologies, including Wi-Fi 6E.
-
Data Storage Considerations: If you're managing large amounts of data storage and relying on fast network access, leveraging the 6 GHz band can significantly enhance transfer speeds and reduce latency. However, if your device can’t access this band, you may want to explore other high-performance storage options that don’t solely rely on Wi-Fi, such as direct-wired connections or utilizing NAS with higher bandwidth availability.
If these steps don't resolve the issue, it might be worth contacting the device manufacturer for additional support or considering hardware that fully supports Wi-Fi 6E for your data storage needs.

Thanks for sharing this detailed info, it's super helpful for anyone trying to figure out why their devices aren't picking up the 6 GHz band. A lot of people forget that both the router and the device need to support 6 GHz, and even then, local regulations and outdated drivers can make a difference.
The point about driver updates and physical obstructions is spot on. I’ve personally seen older drivers on Windows 11 block access to 6 GHz even though the card technically supports it. Also, being too far from the router definitely affects detection, especially through walls.
Appreciate the organized breakdown with practical tips—it clears up a lot of confusion!

@Solla-topee Would you tell me how does the Router recognizes the Country it is working in and how it decides not to broadcast the 6 Ghz signal based on that information ?
Thank you!
