Situation 1: Unable to Detect the Specific WiFi Signal to Connect

If you can't find the specific WiFi signal you want to connect to, follow these steps:

1. Check the Distance and Signal Strength
First, confirm whether the network card is too far from the WiFi router, which may result in a weak signal.

2. Verify the WiFi Name
Check if the WiFi name contains special characters, non - Latin letters (such as Chinese, Japanese, Korean, Russian characters), emojis, or a combination of multiple types of characters. When the system language settings, font support, or character encoding parsing ability of devices (such as mobile phones, computers, tablets) are insufficient, these characters may not be displayed correctly, leading to a garbled - name issue.

3. Check if the WiFi Signal Is Hidden
If the router's wireless signal is hidden, you can either unhide it in the router settings. Alternatively, you can connect to the hidden WiFi in the  "Connect to a hidden network" option. Enter your WiFi name and password to establish the connection.

Situation 2: Unable to Detect Any Wireless Signals

If you can't detect any wireless signals, conduct the following troubleshooting steps:

1. Check the Network Card in Device Manager
Examine the "Network adapters" section in the computer's Device Manager to see if the USB wireless network card is recognized. Check if there is an exclamation mark next to the device. If there is, it indicates a driver problem. You can try unplugging and plugging the network card back in. If the exclamation mark still exists after this operation, you need to reinstall the network card driver.

2. Verify the Wireless Service Status
If the network card appears normal in the Device Manager (no exclamation mark), check whether the system's wireless service is enabled. The specific steps vary by operating system:
