Configuring access point settings for stable operation

By default iPhone 11 distributes Wi-Fi in the range 2.4 GHz, which provides better compatibility with older devices, but may suffer from interference. If you have a modern receiving smartphone (e.g., iPhone 13 or Samsung Galaxy S22), we recommend switching manually to 5 GHz For greater speed, you can do it like this:

Open Settings → Tethering → Max Compatibility And turn it off this parameter. Now the iPhone will distribute the network in the range 5 GHz, if supported by the connected device. Please note: this will slightly reduce the network range, but the data transfer speed will increase by 2-3 times.

A critical detail: if you've enabled Wi-Fi hotspot but the internet isn't working on the second phone, check your carrier's APN settings. Sometimes they reset after an iOS update. You can find the correct APN settings on your mobile carrier's website or request them from support.

Alternative ways to share internet from iPhone 11

Wi-Fi isn't the only way to share the internet. In some situations, it's more convenient to use Bluetooth or USB connectionLet's consider when it's worth choosing these methods:

• 🔵 Bluetooth: Suitable if you need to share the internet for a long time (for example, in a car). Battery consumption is lower than with Wi-Fi, but the speed is limited to ~1-2 Mbps. To activate, turn on Bluetooth on both devices, then Settings → Tethering on iPhone, select Connecting via Bluetooth.
• 🔌 USB: The most reliable method if you have a cable Lightning-to-USBThe speed is comparable to Wi-Fi, and your iPhone doesn't drain (in fact, it charges from the second device). Connect the cable, then select USB only.
• 📶 Internet Bridge mode: Useful if you have access to wired internet (for example, at a hotel). Connect your iPhone to the Ethernet via an adapter. Lightning-to-Ethernet, then share Wi-Fi as usual.

Each of these methods has its advantages. For example, USB connection Indispensable if you need to distribute the Internet to a laptop without a Wi-Fi adapter. And Bluetooth This is a great option when battery saving is important, but high speed isn't essential. Remember, you can only use one sharing method at a time.

How to save data and battery when sharing Wi-Fi

Tethering consumes both mobile data and battery power. To avoid unpleasant surprises at the end of the month, follow these tips:
