Cause one: The firmware version of the router is too low, or the firmware and hardware do not match, which may also cause the router to work improperly, resulting in unstable WIFI connection problems. Action: Turn off these devices, or install the router somewhere with relatively little interference.
Reason 3: Mobile phone WIFI function BUG, some mobile phone WIFI software design may have bugs, such as opening the power saving mode, resulting in mobile phone WIFI automatically shut down when idle. Or compatible with the router, causing other WIFI devices to drop offline. Action: Upgrade your phone's system to the latest version, turn off power-saving mode or other options that may shut down WIFI, and report back to the phone manufacturer.
Reason four: The wireless signal is weak, the router WIFI transmission power is too small, or the device is too far away from the router, and there is a shield in the middle. The WIFI signal is too weak, and the line will be dropped from time to time. Countermeasures: Set the transmission power of the router to be high to enhance the transmission signal, in addition, the linear distance between the mobile phone and the router should not be too far away, and the middle should not be separated by too thick cement walls and shields.
Reason five: Multiple WIFI signals are concentrated in a channel, most wireless routers in the factory default channel is 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 repeat.
Cause six: viruses, the router itself is less likely to be poisoned, mobile phones or wireless devices are more susceptible to poisoning, some viruses will occupy most of the bandwidth in the background or cause a drop in the line. Solution: Install antivirus software to remove viruses from wireless devices, and restore the router or wireless device to factory Settings if necessary.
Cause seven: Hardware failure, router WIFI transmitting module or mobile phone WIFI receiving module hardware itself failure, welding and other reasons, resulting in WIFI hardware can not work normally, there is a drop in the situation. Countermeasure: The first recommendation is to contact the manufacturer for after-sales testing and maintenance as far as possible, if the warranty period has passed, children's shoes with professional knowledge and hands-on ability can be repaired by themselves.
