Cannot Connect to 5GHz Freebox Pop Network (Archer T600U Nano)
My Archer T600U Nano adapter sees the 5GHz network from my Freebox Pop router (Freebox-XXXX-5g), but it fails to connect with the error: "Could not connect to this network." The 2.4GHz connection works perfectly. I have tried the following troubleshooting steps without success:
1. Driver: Installed the latest official driver from TP-Link website (please specify your OS, e.g., for Windows 10/11). I also tried uninstalling/reinstalling
2. SSID Separation: The 2.4GHz and 5GHz networks are separated (e.g., Maison_2G and Maison_5G).
3. Router Settings (Freebox Pop): The 5GHz band is forced to use WPA2-PSK/AES only (no WPA3 or TKIP).
4. Channel/Bandwidth: Tested low, non-DFS channels (36, 40, 44, 48). I also forced the channel width to 40MHz (instead of 80MHz).
5. Power Management: Disabled the "Allow the computer to turn off this device to save power" option for the adapter in Device Manager.
Hello @issaml ,
Thanks for contacting our community.
Please try changing your router’s Wi-Fi name (SSID) and avoid using special characters. If you need help with this, please contact your router’s support.
Also, please try to change the wireless Mode of 5GHz to 802.11ac. Take TP-Link router for an example:
