In today's world, mobile internet has become an indispensable tool, allowing you to stay online anywhere. Situations where a fixed router is unavailable or a provider outage occurs require a quick search for alternative solutions for accessing the internet. Laptops from this brand ASUS, which have a wide range of network adapters, are ideal for setting up such a temporary connection via a smartphone.
Using your phone as a hotspot isn't just a way to save data, it's also an effective way to ensure data privacy in public places. Instead of risking access to open networks in cafes or airports, you create a personal, secure communication channel. This is especially useful for using banking apps or corporate email on your device. ASUS.
In this guide, we'll cover every detail of setting up a connection, from the basic principles of tethering to fine-tuning power-saving settings. You'll learn how to avoid draining your smartphone's battery and how to ensure maximum data transfer speeds between devices.
How tethering and hotspot modes work
The technology that allows you to broadcast mobile Internet to other devices is called modem mode or TetheringIn this process, your smartphone acts as a router, receiving a signal from a cell tower (3G, 4G, or 5G) and converting it into a local Wi-Fi network. Laptop ASUS sees this network as a normal home connection and establishes a connection in the standard way.
It's important to understand the difference between a Bluetooth modem and a Wi-Fi hotspot. The former offers lower speeds but uses significantly less power, while the latter allows for high speeds comparable to home internet. For full-featured work with heavy web pages and video content on a laptop Wi-Fi tethering is the only choice.
⚠️ Please note: When activating a hotspot, your mobile operator may automatically change the traffic type or limit the speed if your plan doesn't include tethering. Always check your plan's terms in your operator account before using it.
The data transfer process takes place in a secure encryption mode, usually WPA2-Personal or more modern WPA3This means that the data passing from the phone to the laptop ASUS, are protected from interception by nearby intruders. However, the security of the final connection also depends on the laptop's settings and the antivirus software installed.
The influence of signal frequency on speed and range
Modern ASUS smartphones and laptops support two bands: 2.4 GHz and 5 GHz. The 5 GHz band offers significantly higher data transfer speeds and is less susceptible to interference from neighboring networks, but has a shorter range and is less effective at penetrating walls. The 2.4 GHz band is slower, but more stable over distance and penetrates obstacles better. If your laptop is close to your phone, 5 GHz is preferable for maximum performance.
Preparing your smartphone for Wi-Fi sharing
Before attempting to connect your laptop ASUS, you need to set up the signal source correctly. On smartphones running Android This process may vary slightly depending on the operating system version and the manufacturer's shell (e.g. One UI from Samsung or MIUI (from Xiaomi). The basic algorithm remains the same for most devices.
First, make sure your phone's mobile data is enabled and you have a strong network signal. Creating a hotspot without an active internet connection is pointless. Next, go to Settings, then under "Location," "Network & Internet" or "Connections."
- 📱 Find the "Tethering & portable hotspot" option in your Android smartphone's settings menu.
- 🔒 Set a strong password to protect your network from unauthorized access by third-party devices.
- 📡 Select the frequency band (2.4 GHz or 5 GHz) depending on the specifications supported by your ASUS laptop.
- 🔋 Check your battery level, as using Wi-Fi significantly increases energy consumption.
Particular attention should be paid to the network name (SSID). By default, it often contains your phone model, which can reveal information about your device to potential attackers. It's recommended to change the access point name to a neutral one that doesn't contain personal information to increase anonymity when using it in crowded areas.
Setting up a hotspot on Android and iOS
In the operating system Android The access point setup interface may vary, but the key settings remain the same. After entering the "Wi-Fi Hotspot" menu, toggle the switch to "On." Here you can also set the automatic shutdown time to conserve battery life if no one connects to the network for a long time.
For device owners Apple (iPhone) The process is further simplified thanks to ecosystem integration. The feature is called "Personal Hotspot" and is located in the main settings. When you first turn it on, the system will prompt you to activate the feature if it was previously disabled. Devices ASUS With Windows 10 and 11, they see the iPhone perfectly as a standard Wi-Fi network.
An important aspect is the security settings. The encryption protocol should be set to WPA2 PSK or higher. Using an open network or an outdated protocol WEP This is unacceptable, as it makes your data vulnerable. The password must be at least 8 characters long, including letters and numbers.
☑️ Check settings before connecting
Some smartphone manufacturers are implementing smart sharing features that allow you to connect devices without entering a password if they are in your contacts or use the same account. For laptops ASUS Under Windows, this may not work directly, so manually entering the password remains the most secure method.
How to connect an ASUS laptop to a network
Once the hotspot on your phone is activated, you need to go to your laptop settings. ASUSIn the operating system Windows Wireless networks can be managed from the taskbar or the settings menu. Click the globe or Wi-Fi icon in the lower right corner of the screen, next to the clock.
In the list of available networks that opens, find the name (SSID) you set on your phone. This may differ from the phone's name if you changed it in the settings. Click on the network name and press "Connect." The system will prompt you to enter the security key.
Path to adapter settings:
Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings
Enter your password, making sure to be case-sensitive, as the system distinguishes between uppercase and lowercase letters. After successful authentication, Windows will assign a network profile (public or private). For a home network or a trusted phone network, it is recommended to select the "Private" profile, which will allow your laptop ASUS be visible to other devices on the network if needed for printing or file sharing.
| Parameter | Recommended value | Description of influence |
|---|---|---|
| Security protocol | WPA2-Personal / WPA3 | Provides encryption of traffic between your phone and laptop |
| Frequency range | 5 GHz (preferred) | High speed but shorter signal range |
| Wi-Fi channel | Auto or 36, 40, 44 | Selecting a clear channel reduces interference levels |
| Max. number of users | 1-3 devices | Limiting the number of connections saves speed and battery |
If the connection is successful, the Wi-Fi icon in the tray will change and the message "Connected, secure" will appear. Now the laptop ASUS Uses your phone's mobile data to access the internet. You can open a browser and check if the connection is working.
Diagnostics and problem solving
Despite the simplicity of the procedure, users sometimes encounter difficulties. One of the most common problems is when the laptop ASUS The network is visible but fails to connect, returning the error "Unable to connect." This is often due to the incorrect security type or incompatible encryption standards.
Another common cause of failures lies in the drivers of the laptop's wireless adapter. If the drivers Wi-Fi module If the firmware is outdated or not working properly, the device may not support the modern security protocols that the smartphone uses by default. In this case, you need to update the software through the Device Manager or the official website. ASUS.
- 🔄 Restart both devices: This clears temporary network errors and the DNS cache.
- 📶 Get closer: Make sure the distance between your phone and laptop is no more than a few meters.
- 🔌 Disable your VPN: Sometimes active VPN connections on your phone block internet tethering.
- 🛡️ Check your antivirus: the firewall on your laptop may be blocking the new network connection.
⚠️ Important: If your ASUS laptop connects but the internet is not working (status "No internet access"), check your SIM card balance and mobile data allowance. Also, make sure your phone's "Data Saver" mode isn't enabled, as this can block background data transfers for other devices.
In some cases, "forgetting" the network on your laptop can help. To do this, right-click the network name in the list of known networks and select "Forget," then try connecting again with the password. This clears any old configurations that may have been saved incorrectly.
Speed optimization and energy saving
Sharing Wi-Fi is a power-hungry process that quickly drains your smartphone's battery. To minimize losses, keep your phone's screen off and close background apps consuming data. For a laptop ASUS, in turn, it is also worth disabling the ability to turn off the Wi-Fi adapter to save energy in the Windows Device Manager.
To improve connection stability, it's recommended to limit the number of devices connecting to your hotspot. If too many devices connect to your hotspot, your laptop's speed may drop to unacceptable levels. You can set a user limit in your Android hotspot settings, such as 1 or 2 devices.
Using a USB cable to connect your phone to your laptop ASUS USB tethering is a great alternative to Wi-Fi. This method simultaneously charges your phone and provides a more stable connection without radio interference. However, it requires a cable and physically tethers the devices.
It is also worth considering that some telecom operators use the technology NAT, which may interfere with the operation of certain games or torrent clients on a connected laptop.

Why doesn't my ASUS laptop detect my phone's hotspot?
Most often, the problem stems from incompatible frequency bands. If your phone only broadcasts on the 5 GHz band, and your ASUS laptop's Wi-Fi module is old and only supports 2.4 GHz, the devices won't see each other. Solution: Change the access point settings on your phone, selecting the 2.4 GHz band or "All Bands."
How can I find out how much traffic my laptop has used?
In the Android hotspot settings (under "Data Usage" or "Statistics"), you can see the amount of data transferred to connected devices. You can also check the detailed costs in your mobile operator's account, where traffic is usually broken down by device or connection type.
Does connecting a laptop affect call quality?
4G and 5G networks use VoLTE technology, which allows you to simultaneously talk on the phone and use the internet without losing quality. On older 3G networks, an incoming call can cause your laptop's internet connection to drop or slow down significantly as the channel switches to voice mode.
