For example, the signal of some miscellaneous wireless routers will be relatively weak, and there will be no connection, and the wireless signal is transmitted in a straight line, if you encounter obstacles (such as walls) during transmission, the signal strength of wireless communication will be weakened, and it will not be searched. It is recommended that you restart your router and mobile phone, disconnect the wireless connection of mobile phones on the same network, and then bring your mobile phone closer to the router to see if it can find the signal.
