Just a few words, the range is so wide, who knows why you can't connect.

Do you have the conditions to connect, do you have the equipment you should have, if so, then under what circumstances can you not connect, and whether the connection password is correct, whether it is connected, no network, or just can't connect.

There is also how far away you are from the hotspot, it is definitely impossible to connect if it is too far, whether the router is on.

3. Restart the router.

Disconnect the router from power, power it back on after 10 seconds, and wait for the router to boot up and connect to the carrier network (about 1 2 minutes is expected).

4. Check the router settings.

Check the router manual, enter the router settings interface to see if there is a restriction on connection, if it is restricted, you will not be able to connect to wifi.

5. Use other mobile phones around you to compare and test.

Use the comparison method to observe other mobile phones connected to the same wifi to confirm whether it is the wifi cause or the mobile phone reason, and you can also connect your mobile phone to different wifi (or personal hotspots) for comparison test. If other phones can't connect to wifi, it's a router or broadband problem.

6. Upgrade the system version.

The new version of the system has improved the compatibility and stability, optimized the performance, and entered Settings - System Upgrade (some models are: Settings - My Device - iQOO UI Version), you can view the system version information. If it's not the latest version, it's recommended to upgrade the experience.

7. Restore factory settings.

Abnormal system configuration information may cause failures, so we recommend that you back up important data and restore all settings.

Operation method: Enter Settings - System Management - Backup and Reset - Restore All Settings (some models are: Settings - More Settings - Restore Factory Settings - Restore All Settings), operate according to the on-screen prompts, the operation will cause the logged third-party software to need to log in again, but will not clear the **, ** and other files in the phone storage, please confirm that it does not affect the use of some third-party software before restoring all settings.

To avoid data loss due to abnormal operation, it is recommended to back up the important data of your phone first.

The key is what kind of Android system are you talking about, and what kind of system is the mobile phone? Is it a Xiaomi phone, a Redmi phone, or an OPPO phone? If your mobile phone really fails, why don't you go to after-sales maintenance and let someone repair it for you.
