If the phone hotspot cannot be turned on or connected, you can follow the following steps to check: 1. Check whether the phone hotspot is turned on, whether the SSID and password are correct, and whether the number of devices exceeds the limit, try restarting the phone or resetting the hotspot settings; 2. Make sure that the computer Wi-Fi is turned on, switch flight mode, update the network card driver or check the USB connection mode; 3. Run network troubleshooting, manually release/renew the IP address or reset the TCP/IP protocol; 4. Update the driver, use the system to restore, and eliminate firewall interference. Most cases can be solved by restarting the device and updating the driver.
The fact that the mobile phone cannot be turned on or connected is a common problem for Windows users. This situation is particularly troublesome when you need to temporarily use a computer to surf the Internet. Don’t worry, check a few key points first: Is your network connection normal? Is the hotspot function enabled correctly? Is the driver expired? All of these can be the cause of the problem.
Here are some common troubleshooting directions and solutions:
1. Check whether the phone hotspot settings are correct
Sometimes the problem is not on the computer, but on the phone's settings are not adjusted properly. You can check the following points:
- Is the phone hotspot turned on?
- Are there any incorrect inputs to the hotspot name (SSID) and password?
- Whether the number of connected devices has reached the upper limit (some operators limit up to 3 devices).
- Try restarting your phone or resetting your hotspot settings.
If it is an Android phone, go to "Settings> Network and Internet> Hotspots and Sharing" to view; iPhone will confirm in "Settings> Personal Hotspots".
2. The computer cannot detect hotspot signals
Sometimes, even if you have a hot spot, but the computer cannot search for the signal, it may be related to the wireless network card:
- Make sure the computer's Wi-Fi function is turned on.
- Try to switch flight mode and turn it off and refresh the wireless module.
- Check whether the network card driver is the latest version, or try to update/rollback the driver.
- If using a USB-share network, make sure the cable is plugged in tight and select the correct connection mode on the phone (such as "File Transfer" or "USB Network Sharing").
If you are not sure about the status of the network card, you can expand "Network Adapter" in "Device Manager" to see if there is a yellow exclamation mark.
3. IP address acquisition failed or no network after connection
Although the hotspot is connected, it shows "No Internet access" or "Unidentified Network". At this time, the problem may be in the network configuration:
- Run the Network Troubleshooter (which comes with Windows) on your computer to automatically fix it.
- Try to manually release and renew the IP address:
- Open Command Prompt (CMD)
- Enter
ipconfig /releaseand press Enter - Enter
ipconfig /renew
- Or try resetting the TCP/IP protocol:
- In CMD, enter:
netsh winsock reset netsh int ip reset
- Restart the computer after completion.
- In CMD, enter:
4. Compatibility failure caused by driver or system problems
Sometimes, system updates or driver incompatibility can cause hotspots to fail, especially after upgrading to Windows versions:
- Update the wireless network card driver and go to the official website to download the latest version of the corresponding model.
- If you can connect to the current situation before, you can try "system restore" and return to the normal time point.
- Check if there are third-party firewalls or antivirus software that blocks hotspot connections.
Basically these common reasons. In most cases, restarting the device and updating the driver can be done. If it still doesn't work, it is recommended to try a different phone to rule out whether it is a problem with the phone itself.
