This situation is generally manifested in the configuration of the mobile phone is different, another is the space memory of the mobile phone is not enough, one is the service life of the mobile phone is different, the hardware may not keep up, will age, and different brands of mobile phones, this situation will also occur.
In addition, usually also pay attention to the network card of the mobile phone, usually run when the card is not card. Just like the computer, not used for a long time, hardware aging, it will be directly used.
1. Router blind area
The WiFi signal is transmitted through the router, but many families are accustomed to placing the router in the corner of the room, coupled with barriers such as walls, and it is easy to appear signal blind areas. If the location is in the signal blind area, the signal is naturally worse than others.
2, WiFi signal congestion
If multiple devices are connected to a WiFi channel resource at the same time, it is easy to cause signal congestion, resulting in unstable network connections.
3, router frequency limit
Many routers can only work in the 2, 4GHz band, and multiple connected devices are easy to interfere with each other, resulting in signal instability. If the router is aging, it is more likely to experience network problems.
4. Differences in mobile devices
Do not use different brands of mobile phones, the use of WIFI chip model, quality are different, the use of better performance of WIFI chip, the work performance will naturally be better when connected to WIFI.
Good performance, powerful configuration of the non-card, low configuration of the affirmative card
