Why can't I connect to wifi after my phone is disconnected?

1, signal interference: There may be strong signal interference sources near the router, such as microwave ovens, magnets, high-voltage lines, etc. The wireless signals and strong magnetic fields emitted by these devices will seriously affect the normal sending and receiving of WIFI signals on the router.

Solution: Turn off these devices, or install the router in a place with relatively little interference.

2. Router firmware problem: The router firmware version is too low, or the firmware and hardware do not match, which may also cause the router to work abnormally, leading to the problem of unstable WIFI connection.

Solution: Go to the router official website to find the latest firmware of the corresponding model, and upgrade the router firmware according to the instructions.

3, mobile phone WIFI function BUG: There may be bugs in the design of individual mobile phone WIFI software, such as turning on the power-saving mode, which will automatically turn off the mobile phone WIFI when it is idle. Or router compatibility problems, leading to other WIFI devices disconnected.

Solution: Upgrade the mobile phone system to the latest version, turn off the power-saving mode or other options that may cause WIFI to turn off, and feed back to the mobile phone manufacturer.

4. Weak wireless signal: the transmitting power of the router WIFI is too small, or the device is too far away from the router, and there is shielding in the middle. WIFI signal is too weak, and the network will be disconnected from time to time.

Solution: Set the transmitting power of the router high to enhance the signal transmission. In addition, the straight-line distance between the mobile phone and the router should not be too far, and there should be no thick cement wall and shield in the middle.

5. Multiple WIFI signals are concentrated in one channel: most wireless routers leave the factory with the default channel set to 6. If there are multiple wireless routers nearby, the same channel may affect each other.

Solution: Change the router channel to a channel other than 6, and try to change the SSID number to a name that will not be duplicated.

6. Hardware failure: The hardware of the router WIFI transmitting module or the mobile phone WIFI receiving module itself fails or is welded, which causes the WIFI hardware to fail to work normally and leads to disconnection.

Solution: First contact the manufacturer for after-sales inspection and maintenance. When the warranty period expires, children's shoes with professional knowledge and hands-on ability can be repaired by themselves.
