Typically, the path is through the section Settings, further Connections or Network and Internet, where is the point Access point and modemIt is here that all the necessary control levers are concentrated.
When first turned on, the system is often prompted to set a network name (SSID) and password. It is recommended to use a strong password with mixed uppercase and lowercase letters and numbers to prevent unauthorized connections. Standard security protocol WPA2 PSK is the optimal choice for compatibility with both old and new devices, although WPA3 provides better security.
In the advanced settings, you can change the Wi-Fi frequency band. If your laptop supports 5 GHz, it makes sense to switch to this band for higher speeds and less interference, but the signal range will be shorter. For older laptops, leave the frequency band set to [unspecified]. 2.4 GHz.
- 🔒 Set a strong password to protect your personal information.
- 📶 Select the 2.4 GHz band for maximum compatibility.
- 👀 Hide your network name (SSID) if you want to increase your privacy.
- 📊 Monitor the number of connected devices in the status menu.

How to enable Personal Hotspot on iPhone (iOS)
For users Apple luckily, we have an even simpler integration of a feature called "Tethering Mode." To activate it, just go to Settings and select the corresponding item in the main menu. If you don't see this section, your operator may not have configured the profiles automatically, and you'll need to manually enter the APN settings in the menu. Cellular → Cellular Data Network.
A unique feature of the ecosystem Apple is a function Instant HotspotIf your laptop (MacBook) and iPhone use the same Apple ID, you won't even need to enter a password to connect—the device will automatically prompt you to connect to the internet. This works thanks to Bluetooth Low Energy technology, which constantly scans the surrounding area for Apple devices.
It's important to note that there's no option to manually change the Wi-Fi frequency band on the iPhone—the system automatically selects the optimal option based on the connected client and environmental conditions. It's also worth remembering that when tethering is active, the iPhone screen may appear brighter than usual, which further drains battery power.
- 🍏 Use Instant Hotspot to instantly connect your Mac.
- 🔐 You can change the password in the modem settings.
- 📶 Allow other users to connect only when necessary.
- 🔄 Update iOS to the latest version to fix network bugs.
⚠️ Attention: On some iPhone models, the tethering feature may not work correctly when using cases with metal inserts or magnetic mounts, as they shield the antenna.
Alternative methods: USB and Bluetooth
While Wi-Fi is the most popular method, it's not always ideal. If you need maximum connection stability and minimal latency (ping), it's better to use a wired connection via USB cableThis method not only ensures more stable data transfer but also simultaneously charges the smartphone, which is critical for long-term use.
To activate USB modem on Android, connect your phone to your laptop with a cable, then toggle the switch in the hotspot menu USB modemOn Windows, a new Ethernet adapter will appear in Network Connections. On iPhone, simply enable Personal Hotspot and connect the cable; the system will automatically recognize the device as a network card.
The way through Bluetooth This is the least productive and is used extremely rarely, primarily as a backup option when the Wi-Fi module is damaged or busy. Transfer speeds are significantly lower, and pairing takes longer, but the phone's battery drain is minimal.
Why is a USB modem better than Wi-Fi?
Connecting via USB eliminates packet loss typical of wireless networks, ensuring a stable ping, which is critical for online gaming and video calls. Furthermore, the phone doesn't overheat as much as when the Wi-Fi module is emitting radiation.
- 🔌 The USB cable provides a stable connection without loss of speed.
- 🔋 Wired connection charges your phone while you work.
- 🐌 Bluetooth is only suitable for text messaging due to its low speed.
- 🛡️ The USB connection is protected from external radio signal interception.
Solution and troubleshooting
Even with proper configuration, situations may arise where the laptop doesn't see the network or can't connect to it. Often, the problem lies with the network adapter drivers on the computer or the phone being stuck in standby mode. Try turning airplane mode off and on again on your smartphone to restart the radio module.
If your laptop detects the network but displays "No Internet Access," check if your phone's mobile data connection is working. An incorrect password or IP address conflict could also be the cause. In such cases, deleting the saved network on your laptop and creating a new access point with a different name can help.
Sometimes your antivirus or firewall software may block a connection to a new network, classifying it as a public network with strict rules. Check your network profile settings in Windows and ensure the checkbox for allowing device discovery is selected.
⚠️ Attention: Settings interfaces and menu item layouts may change after an operating system update. If you can't find the item described, search your phone's settings by entering the word "modem" or "hotspot."

Frequently Asked Questions (FAQ)
Why does my phone's battery drain quickly when using Wi-Fi?
When operating in hotspot mode, the Wi-Fi module consumes significantly more power than in normal mode because it is constantly emitting a signal. Furthermore, if the phone is simultaneously receiving a weak 4G signal and broadcasting it, the processor and modem operate in boost mode. It is recommended to keep the phone charged or use a power bank.
Is it possible to share Wi-Fi if my phone has a SIM card without a data plan?
Technically, you can enable a hotspot, but the connected devices won't have internet access because the phone has nothing to share. However, you can use your phone as a Wi-Fi repeater (only on some Android models) to broadcast an existing Wi-Fi signal further, but this is a complex and uncommon configuration.
How do I know who is connected to my hotspot?
Most modern smartphones have a "Connected Devices" section in the hotspot settings menu, which displays a list of devices and their IP addresses. You can also block access for a specific device or change the password to reset all connections.
Does tethering affect mobile connection speed?
Yes, the channel's bandwidth is divided among all connected clients. If several laptops connect to your phone and start downloading updates, the speed on each will drop. Furthermore, the signal broadcasting process itself puts additional strain on the phone's modem.
