Troubleshooting Guide: 1. What can I do if no WiFi signal can be detected? 1 Check if the WiFi function of the nearby router work properly when connected to the cell phone directly. 2 Reduce distance between the USB WiFi adapter and the router for a try, and avoid the obstacles such as thick walls, metals or large-area mirrors. 3 Check whether the wireless router and wireless AP have settings to hide the wireless network name. 2. What can I do if the WiFi signal can be detected, but cannot be connected successfully? 1 Check the signal strength of the router. Try to connect the WiFi in a place that has a stronger signal. 2 Ensure you have entered the correct password. 3 Check if the DHCP function of the router has been enabled. If not, the WiFi adapter wont be able to obtain the IP address and connect the internet. 4 Check if you have set the binding of your Mac address and the router. If yes, you need to set the binding of Mac address and the WiFi adapter. 5 Ensure encryption type of your router is one of the WPA-PSK, WPA2-PSK, and 64/128-bit WEP. 3. How can we troubleshoot if the internet speed is slower than we expected? 1 Try to use the WiFi adapter in a place that has a stronger signal. 2 Manually adjust different channels for the router, and find out the optimal channel so that the interference is minimal. 3 Set the router to 2.4Ghz from 5Ghz for a try. 4. What can i do if there is no 5G signal? 1 Ensure your router supports 5G. 2 Check if you have turned on the setting Combine 2.4 GHz and 5 GHz WiFi Network in Wifi setting. If yes, only one wifi signal will be shown. If not, both 5G and 2.4G will be displayed, you could manually choose it.
