There are some situations that WiFi device(computer or phone) cannot find the WiFi name(signal), like can't find 2.4G/ 5G not working /don't show 6G, or it may be a problem with the WiFi device or the network. Please refer to the instructions below.

 

Proper noun : SSID (Service Set Identifier) name is also the WiFi name of the wireless network. 

 

Note：

a. It is recommended to try to use other devices (laptops or other phones) to connect to the same wireless (WiFi) network to confirm whether the same situation exists.

    If it's a computer problem, it's recommended to contact your phone manufacturer for help.

b. After trying to remove the ASUS router, use other devices (laptops or other routers) to connect to your ISP modem to confirm whether situation is the same.

Example picture(1)

Go to Wireless  > General > [Hide SSID], select [Yes] in [Hide SSID] means WiFi name is hidden, select [No] means WiFi name is not hidden.

Example picture(2)

For routers with firmware version 3.0.0.6.102_35404 and later, all WiFi bands for the primary network are enabled by default.

You can simply uncheck the WiFi bands that you want to hide or disable

6. Try to disable the DFS channels

    After enabling DFS channels, it is not recommended to enable DFS channels if there is a lot of signal interference in your wireless environment.

    When the wireless router detects interference, it will automatically check the status of the 5GHz channel. During this inspection period, the 5GHz signal will be temporarily unavailable, and it may take 1 to 10 minutes before it can reconnect.

    Go to [Wireless] > [General], select 5 GHz bands (5GHZ / 5GHZ-2) and uncheck [Auto select channel including DFS channels] to disable the DFS channels

    Please note that 2.4GHz can still be used normally when checking channel availability, so users can use the 2.4GHz band first and wait for the 5GHz connection to resume.

    Please refer to the FAQ [Wireless Router] What is DFS (Dynamic Frequency Selection) and how does it work on ASUS router
