How to solve the wifi signal difference of letv mobile phone

If wifi is a wifi connection, I suggest you click Settings -wlan- Advanced Settings to select Never Sleep, and click Settings -wlan- to find this wifi. Click the small arrow on the right and try again without saving the network. You can also try to restart the router. If this problem still occurs, I suggest you try the wifi network in other environments to see if this problem will occur again. If gprs is connected to the Internet through data traffic, it is recommended that you click Settings-Mobile Network-Access Point APN- Reset to Default and try again. The data connection to the internet is also related to the surrounding environment, weather and location. I suggest you try again in other places where the signal is slightly better. The problem of "unable to access the Internet" is very common. Let me try to guess the problems you may encounter. I suggest you try the method and operate it: 1 I suggest you put this mobile phone card in another mobile phone to see if you can surf the Internet. If you can't access the Internet, please ask the operator if you owe the phone bill. 3 If possible, please put it into Xiaomi mobile phone, turn on the data flow switch, reset the default in Settings-APN, then restart the mobile phone and try again. If you still can't surf the Internet, I suggest you back up your data, restore and clear all the data (turn off the phone, press and hold the volume up+power on button to resume), upgrade your mobile phone to the newly developed system with a wire brush, and don't install the application that requires root permission for the time being to see if it can return to normal. You can set up your phone as follows: 1. Click Settings-WLAN, select the arrow next to the name of the network you want to connect to, select Don't save the network, and then re-enter the password. 2. Restart the phone and router. 3. still not working. I suggest you try whether wifi in other environments can be used normally.
