Why cannot I find my wireless router signal?

People who use wireless networks will encounter problems that cannot find the wireless router signal. I have also encountered this problem before, the wireless network card of the notebook can search for others' signals but cannot find their own router signals. The specific situation and solution are as follows:

I,You can try to borrow another wireless network card to check whether the wireless signal of the router can be found and whether the router is faulty. PCJ

II,Some wireless network adapters may not support 12 or 13 frequency bands. Modify the frequency band of the wireless signal to see the signal within 1 to 11. PCJ

III,When the wireless router is enabled, the wireless WLAN indicator is flashing constantly. The cable enters the router management interface and confirms whether the wireless function is enabled. PCJ

IV,The final killer is to restore the factory settings of the wireless router and then re-search. PCJ

V,Adjust the location of the wireless router or wireless network card to avoid the wireless network card in the router signal blind zone. PCJ

If you cannot find your own router signal, you can try the above situations. There is definitely a solution.
