This method is ideal for desktop work where ping stability is important, such as during video conferences.
Bluetooth pairing requires prior pairing of devices. Bluetooth must be enabled on both devices, after which your device should be found in the list of available devices. iPhone 11 and confirm the pairing code. Speed in this mode is limited by the technical specifications of the Bluetooth protocol and rarely exceeds 1-2 Mbps, making this option a backup.
☑️ Check before connection
Solution: Why can't I see the access point?
Users often encounter a situation where their laptop or tablet simply doesn't detect the network created by their smartphone. This could be caused by a software glitch, frequency incompatibility, or hidden security settings. First, try turning the tethering mode off and on again. iPhone, and also reboot the Wi-Fi module on the receiving device.
One common cause is operating in the 5 GHz band, which not all older devices support. In the modem settings, you can enable the "Maximum Compatibility" option, which will switch the connection to the 2.4 GHz frequency. This will slightly reduce the maximum speed, but significantly increase the likelihood of network detection by older laptops or gaming consoles.
⚠️ Warning: If you're using antivirus software or a firewall on your computer, they may be blocking connections to new networks. Check your network card's security settings.
The problem could also be caused by a full network settings cache. In this case, resetting the network settings on your smartphone can help. Go to Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsPlease note that this action will delete saved passwords from other Wi-Fi networks, but will not affect your personal data, photos, or contacts.
Hidden operator settings
Sometimes your carrier profile requires manual adjustment of APN parameters for tethering to work. If the tethering button is missing or inactive, contact your carrier's support team to obtain the correct access point settings.
The impact of internet distribution on battery charge and temperature
