? The network connection may fail due to the following reasons.
1. The DHCP service may be faulty.
In AP mode, the DHCP service is provided by a router or other network device. If the DHCP service is faulty or incorrectly configured, the IP address cannot be obtained and the network cannot be connected.
2. The cable connection may be faulty.
Check whether the cable connection is secure and whether the network cable works properly.
If there is a problem with the wired connection, network data cannot be transmitted properly.
3. The AP mode may be incorrectly set.
Ensure that the AP mode is configured correctly and matches the Settings of the network device.
You may need to check the SSID name, password, encryption and other Settings to ensure that they are the same as the wireless router.
4. The wireless signal strength may be insufficient.
Ensure that the distance from the wireless router is moderate and that physical obstacles are not allowed to block the signal.
If the signal strength is insufficient, the network connection may not be stable in AP mode.
Hope the above answers are helpful to you.
If the problem persists, it is recommended that you further examine the network device and related Settings, or contact your network service provider for technical support.
At this time, because the computer and mobile phone have no IP address, they cannot communicate with the router, and naturally they cannot access the Internet.
Second, solutions
There are 3 ways to solve the problem that the router cannot access the Internet after turning off DHCP:
Restore the router to factory Settings
Enabling DHCP
Configure static IP addresses for computers and mobile phones
