The WIFI connection without 5G is not mainly due to router failure, multiple devices connected together, and beyond the signal range, which will cause the connection to WiFi.

solution
1, the router failure of this situation, the most suspicious is the power system, so the first thing you should check is the power system, see if the power socket has current, voltage is normal, if the power supply is normal, then see the power cord has no damage, there is no loose, etc., the power cord is damaged, then replace a, loose then reinsert.
2, the wireless router can only connect a maximum of 16 wireless devices, more will not be connected to the situation, WIFI some people can connect, other people can not connect, if someone connects to the WIFI, then the original connection can not connect to the people, and the number is equal. I looked in the route management panel and found that exactly 16 were connected to WIFI, and no more were connected.
(3) Out of the signal range, this problem is generally because the refresh frequency is set beyond the frequency range of the display. Beyond the signal coverage, the direct is the distance, the general ordinary router beyond ten meters signal will become very poor. So when you connect to wifi, get as close to the signal source as possible to enhance the wifi signal.
The WiFi connection without 5G is not available, which may be due to the device requirements of the mobile phone or the requirements of the WiFi format, which needs to consult the relevant customer service to answer.
