Why did Huawei P7 restore the factory settings, but it can t be used when it can connect to the wire

If you cannot access the Internet after connecting to Wi-Fi, it may be caused by incorrect router construction, network problems, and third-party software problems

1. If you use a home network, you need to check whether there are multiple routers cascaded together, you can connect the main router separately to see if you can surf the Internet normally, if so, you need to check whether the cascade network is built correctly.

2. If other mobile phones can access the Internet normally, it is recommended to restart the mobile phone and try again. If other mobile phones can't access the Internet, you can check whether the wireless router network is normal.

3. If you install third-party VPN software, it may cause abnormal WLAN connection, so it is recommended to uninstall it.

4. Use another mobile phone or laptop that can connect to the data network normally, establish a personal hotspot, connect to the hotspot with the mobile phone with the problem to check whether you can surf the Internet, if you can connect to the hotspot to access the Internet normally, please check whether the wireless router settings are correct. If you can't access the Internet even when connected to a personal hotspot, please back up your data and try to restore it to factory settings.

5. It is recommended to restart the router or disconnect other devices and try to check the router settings (the wireless router can limit the MAC address of the access device, the IP end, the number of allowed access devices, and the network speed).

6. Try to do a factory reset or reboot the router.

If the above methods still do not solve the problem, we recommend that you back up your phone data and go to your local Huawei after-sales service center for testing.

It is recommended to check other mobile phones, if the same problem exists, it may be that the Wi-Fi password is wrong or there is a network problem. You can re-enter your password or use a different network.

If the WLAN name contains Chinese or special characters, the mobile phone may not be connected, it is recommended to change the name to a simple combination of English and numbers on the router.

Only when DHCP dynamic address assignment is enabled can the router automatically obtain the IP address. Do not set the dynamic time of DHCP too short, preferably more than 2 hours.

If the network denies access, the hotspot may reach the maximum number of connections. Or it could be that the wireless router has the blacklist (MAC address filtering) feature turned on, and the phone is identified as a restricted access device. The router can be reconfigured and rebooted.

For details on how to set it up, see the router manual. After the configuration, leave the original hotspot on your phone and reconnect it.

Some public hotspots may require you to log in on the web.

1. What happened when the Huawei P7 suddenly turned on with a black screen?

Answer: Please confirm whether you have entered the interface that guides you to update the software, if so, follow the instructions of the mobile phone to upgrade the software to solve this problem of not being able to turn on. Then confirm whether the charging indicator will flash when charging the phone, if not, please go to the branch for testing, if so, please keep the charging state and wait for a period of time before trying to turn on the operation.

If you can force restart and recover by pressing and holding the power button for 10 seconds (note that you can press and hold the power button, not the volume button), if you can restore it, you can solve this problem by upgrading the version. You can also try to use an SD card to force the machine, the specific instructions can be found on the pollen forum, after the strong brush will erase all the previous data, please back up important data in advance.

Android phone can't go to the Internet solution: 1. Restart the phone; 2. Drag down from the top of the screen (or from the bottom to the top) to make sure that "Mobile Data" is on and "WLAN" is off. 3. Go to the mobile phone settings - connection - more networks - mobile network - mobile data (on) - access point name - menu key - reset to the default value (whether the traffic fee generated by the cmnet access point is included in **, please refer to the actual opening**); 4. If you still can't access the Internet after setting, it is recommended to change the phone and card for testing. If you have a specific brand of mobile phone, you can reply:

xx mobile phone can't go to the Internet solution (e.g., Apple phone can't go to the Internet solution, Huawei mobile phone can't go to the Internet solution).

Dear, hello, it is recommended that you try the following operations.

1.Change the password of the wireless router, you can change the WiFi encryption method of the router to: WPA2-PSK, the password encryption method of some routers may not be compatible with mobile phones.

2.Try to reset the static IP address of the mobile phone, go to Settings WLAN Click on the wifi signal you want to connect to Then click on the hidden input method in the upper right corner of the input box to display the advanced options on the IP settings and select static Then according to the gateway address of the router, re-enter the IP address, gateway, network prefix length 24 (the same meaning as the subnet mask), and domain name 1 (the same as the gateway address).

3.It is recommended that you back up your data and restore it to factory settings. Go to Phone Settings - Backup & Reset - Factory Reset - Reset Phone - Erase Everything.

There are several scenarios in which the phone cannot connect to Wi-Fi properly:

1) The wifi signal is set to hidden, you need to contact the network management to obtain the wireless signal name, and manually enter the wireless signal name and password connection in the mobile phone [Settings] - [Wireless LAN] - [Search for other networks].

2) If the router is faulty, try to restart the router.

2. Prompt that the connection to the wifi is refused, and the fault phenomenon: others can be connected, but they can't connect to the wifi, and the connection is refused. Here's how to fix it:

1) The router device may have enabled wireless MAC address filtering, it is recommended to contact the NMS to add the MAC address of the mobile phone. The MAC address is viewed in [Settings] - [About This Mac];

2) If the router is faulty, try to restart the router.

3. The mobile phone connection to wifi prompts that it has been saved, but the connection fails. The solution is as follows:

1) This prompt indicates that the encryption method, password or signal channel of the router of the wifi signal has been modified. It is recommended that the world shed reset the password and encryption type of the router, and the terminal connecting to this network needs to [ignore this network], and re-enter the password to connect.

2) If the router is faulty, try to restart the router.

1. First of all, make sure that your router is not working normally, you can use other mobile phones or digital products to connect to the wifi hotspot If you can connect and surf the Internet normally, then generally speaking, this wireless router can work normally.

2. Secondly, make sure that the mobile phone with a problem with the wifi connection does not have the option to turn off the network in the sleep state, and there are many children's shoes that their mobile phones will be disconnected after a period of time or can not receive the information of the background chat software, most of them are because they inadvertently or mistakenly turn on the option of turning off the network from the mobile phone.

3. Wireless router problem:

1) Dead cycle - many wireless routers sometimes have a connection into a dead loop, that is, they keep getting IP and keep connecting, but they just can't connect to the wifi hotspot. - Let's try the all-purpose fix - restart. After turning off the power of the wireless router completely, turn it back on again after about 10 minutes.

2) Whether there are too many WiFi connected devices - too many digital devices connected to the wifi of a wireless router will put a lot of pressure on the wireless router, and it is easy to cause IP conflicts and cannot be connected - such a problem can be solved by setting a static IP for each device connected through WiFi.

The signal is not good; The password has been changed; denied access; Problems with the system itself.
