Setting up a Wi-Fi hotspot on iPhone 12
The primary and most popular method of sharing is creating a wireless Wi-Fi network. This method is convenient because it doesn't require cables and allows you to connect multiple devices at once. However, it also drains your smartphone's battery the most.
To activate the function, go to the menu SettingsFind the "Personal Hotspot" option. If you don't see it on the main Settings screen, first go to the "Cellular" section—it should be there. Inside the menu, toggle the "Allow Others to Use" switch.
In this window, you'll see the network name, which by default matches your device's name. You can change it to something more descriptive, such as "iPhone_12_Home," to easily identify your network in the list of available connections.
☑️ Check before turning on Wi-Fi
Pay special attention to your password. The system will suggest a standard set of characters, but you can change it to something more complex or, conversely, easier to enter. Remember that password protection is essential to prevent neighbors from using your data.
After turning on the toggle switch, a green bar labeled "Modem Mode" will appear at the top of the screen (where the connection indicators are). This indicates the device is ready to receive connections. Now you can search for a network on your laptop.
There is an important feature of working in the 5 GHz range. iPhone 12 supports this standard, which provides higher speeds but has a shorter range. If your laptop doesn't see the network, try changing the compatibility settings.
Setting up maximum compatibility
If your older devices can't see the iPhone 12 network, enable "Maximum Compatibility" in the Personal Hotspot menu. This will switch the network to the 2.4 GHz band, which will reduce speed but increase range and compatibility.
Connecting a laptop to an iPhone network
Once the hotspot is activated, you need to pair it with your laptop. The process of searching for a network on Windows and macOS is slightly different, but the general principle is the same. Open the list of available Wi-Fi networks on your computer.
Find the name you specified or the one displayed on your smartphone's screen in the list. Click "Connect." The system will prompt you for a password. Enter the character combination shown in the tethering menu on your phone's screen.
After successfully entering the password, the laptop's operating system will establish a connection. A notification will appear on the iPhone screen indicating that one device has connected to the hotspot. The indicator at the top of the screen will turn blue or green, confirming active data transfer.
If your laptop doesn't connect automatically, try forgetting the network in the Wi-Fi settings and then re-discovering it. Sometimes, rebooting the Wi-Fi module on your computer or briefly enabling airplane mode on your smartphone helps.
It is worth considering that when connecting via Wi-Fi Internet speed The speed will depend on the quality of the cellular signal in your location. In areas with poor coverage, your laptop's speed may be unstable.
Sharing the Internet via USB cable
Using a cable to share your internet connection is the most reliable method, ensuring maximum speed and connection stability. Furthermore, with a wired connection, your smartphone doesn't drain its battery; instead, it charges directly from your laptop, which is a huge plus.
To use this method, you'll need an original Lightning to USB or USB-C to Lightning cable, depending on your laptop's port. Using cheap replacements may prevent your computer from recognizing the device as a network adapter.
Connect your iPhone 12 to your laptop. A prompt will appear on your iPhone screen asking "Trust this computer?" Be sure to tap "Trust" and enter your screen unlock passcode. Data transfer will not be possible without this step.
In the "Personal Hotspot" menu on your phone, make sure the feature is enabled. A new wired connection should appear in your computer's network connections. In Windows, it will appear as a network with a monitor icon; in macOS, it will appear as the iPhone USB network interface.
⚠️ Note: When connecting via USB, some versions of Windows may require installation of Apple Mobile Device Support drivers. These are usually installed automatically with iTunes, but in rare cases you may need to download them manually.
The advantage of this method is the absence of latency (ping), which is critical for online gaming or video calls. Wi-Fi is inferior in this regard due to possible interference in the air.
A wired connection also eliminates the risk of neighbors intercepting your data, as you control physical access to the cable. This makes this method preferable when working with confidential information in public places.
Using Bluetooth to transfer data
Although this method is considered obsolete due to its low speed, it can be a lifesaver in an emergency situation when the Wi-Fi module is damaged and there is no USB port. The speed here is limited by the capabilities of the Bluetooth protocol.
First, you need to pair the devices. Turn on Bluetooth on your iPhone 12 and your laptop. Find your phone in the list of available devices on your computer and click "Connect." A confirmation code will appear on your phone's screen, which you'll need to enter on your computer.
Once paired, go to Bluetooth settings on your computer, find the connected iPhone, and select "Connect via" -> "Access Point." You'll also need to enable Bluetooth for tethering on your smartphone.
Bluetooth connection speeds rarely exceed 1-2 Mbps. This is only sufficient for loading pages of text or sending messages in instant messaging apps. Video streaming or file downloads will be extremely slow.
The main advantage of Bluetooth hotspots is their minimal power consumption compared to Wi-Fi. If you need to stay connected for long periods of time and don't have a charger handy, this option can help conserve energy.
