Troubleshooting What if my device failed to detect the 6 GHz Wi-Fi Band of Wi-Fi 6E Routers
Wi-Fi 6E brings Wi-Fi 6 802.11ax into a brand-new frequency, 6 GHz Wi-Fi band. 6 GHz band offers up to 1200Mhz of fresh spectrum, indicating more available channels, higher transmission speed and less latency in a network.
While some users find their phone or laptop is not able to 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 problem.
1. Ensure the Network Device Supports 6 GHz Wi-Fi
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.

PCs or Laptops should be equipped with a 6 GHz Wi-Fi card to be able to see the 6 GHz Wi-Fi network. e.g. 6 GHz network adapters using Intel AX200/AX210 including TP-Link TXE75E 6 GHz PCI-E adapter.
Question: What should I do if only certain device can't see 6 GHz Wi-Fi network?
If several of your 6Ghz devices are successfully connected to the 6 GHz Wi-Fi network, but only certain 6G -compatible device can't see 6 GHz Wi-Fi, this should be due to device itself, please reach the device manufacture directly for more advices and confirm tips here
- 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 6 GHz , etc.
Note: Samsung smartphones has not opened 6 GHz frequency in some areas like HK for now (till July 2022). Reach Samsung Support to learn the updated information of Wi-Fi6E on your device.
2. Update Your Phone or Driver of Wi-Fi card
Given that more devices newly joined in the Wi-Fi 6E device list, it's not surprising that some smartphones or computer Wi-Fi card need an update to support 6Ghz Wi-Fi band.
- For mobile devices : check if an update is available for your phone or tablet and keep the version updated.
- For PCs and Laptops :
find the model of Wi-Fi card, go to Wi-Fi card manufacture website to download and install the latest driver; run the latest Win11 update.
3. 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.
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 open. Here are some countries and areas that have opened Wifi6E for reference.

Countries and Areas that opened Wi-Fi 6E--TP-Link Blog
Some Wi-Fi card may disable the 6 GHz frequency when it detects APs working in an area where Wi-Fi 6E is still under consideration.
Example: when the Wi-Fi card detects the 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.
This is the Wi-Fi 6E limitation on the Wi-Fi network adapter, for this situation, it is recommended to reach device manufacture 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 card may have Wi-Fi6E 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 Intel community that shared the older 22.45.1.1 driver and method of reinstalling the driver.
- Run the latest Win11 update
