ASUS Laptop Won't Connect to Wi-Fi from Phone: A Complete Troubleshooting Guide

You are trying to connect a laptop. ASUS Connect to a hotspot shared from your smartphone, but your device stubbornly refuses to see the network or returns a "Failed to connect" error? This problem is more common than you might think—and the cause may lie in your settings. Laptop Wi-Fi adapter, as well as in the phone's internet sharing settings. In 80% of cases, the problem can be resolved without contacting a service center, but this requires a systematic check of all possible fault points.

In this article we will look at 7 Key Reasons, according to which ASUS ZenBook, VivoBook, ROG or another model may ignore Wi-Fi from the phone - whether it be iPhone, Samsung, Xiaomi or HonorYou will receive step-by-step instructions with illustrations (for Windows 10 and 11), a protocol compatibility table, and A unique checklist for diagnosing a problem in 5 minutesWe'll pay special attention to pitfalls like IP address conflicts or outdated drivers, which are often overlooked.

Let us warn you right away: if your phone is distributing the Internet through USB cable (mode USB-tethering), rather than via Wi-Fi, is a different story. Here, we're focusing exclusively on wireless connectivity, where the smartphone acts as a router. Also, don't confuse this issue with a lack of internet access. after connections (when the network is visible, but the pages don't load) is a topic for a separate article.

1. Checking the Basic Conditions: 4 Steps Before Diagnosis

Before delving into the settings, make sure the basic requirements for a successful connection are met. Experience shows that in 30% of cases, the problem is resolved at this stage.

• 🔋 Charging your phoneIf the battery level is below 20%, many smartphones automatically disable Wi-Fi hotspot access to save power. Connect your phone to a charger and restart the hotspot.
• 📶 Airplane mode: Check that the Airplane mode is disabled on your phone (even if the icon is not lit, sometimes it is activated by software). Android: swipe down the notification panel; iPhone: check in the Control Center.
• 🔄 Restarting devicesTurn off and then turn on your phone, then your laptop. This will clear temporary errors in your network adapters.
• 🔒 Wi-Fi password: Make sure you are entering the correct password (on iPhone it is displayed when the distribution is turned on, Android (You can change it in the access point settings). The password is case sensitive!

If after these manipulations the laptop ASUS If you still can't see the network, move on to the next section. If the network is visible, but the connection is lost, the problem is most likely in IP settings (section 4) or adapter drivers (section 5).

2. Hotspot settings on your phone: what could go wrong

A phone as a router is a simplified version of a full-fledged router, and it has its limitations. Let's look at common configuration errors that block a laptop's connection.

2.1. Incorrect frequency range (2.4 vs. 5 GHz)

Most laptops ASUS (especially models older than 2018) do not support Wi-Fi 6 (802.11ax) and may not see networks distributed in the range 5 GHzBy default, many phones (for example, Samsung Galaxy S22+ or iPhone 13 Pro) distribute the internet on the 5 GHz band for greater speed. Solution:

1. On Android: go to Settings → Hotspot & tethering → Set up Wi-Fi hotspot and select 2.4 GHz in the "Range" section.
2. On iPhoneUnfortunately, Apple doesn't allow you to select a range manually. Try turning off Wi-Fi on your laptop, turning it back on, and refreshing the network list.Win + A → Wi-Fi → Refresh).

2.2. Network Name (SSID) Conflict

If your access point name (eg. MyHotspot) matches the name of your home network or another previously saved one, Windows may be confused about priorities. Rename the access point on your phone using a unique name (for example, Phone_Hotspot_555). Avoid Cyrillic and special characters—they can cause errors on some adapters.

2.3. Limit on the number of connected devices

Many phones by default limit the number of simultaneously connected devices to 1-3. If, for example, a tablet or laptop is already connected to your hotspot, ASUS may not see the network or receive an authentication error. Solution:

• 📱 On Android: In the access point settings, find the “Max. number of devices” option and increase the value to 5–10.
• 🍎 On iPhone: The limit is hard-coded at 3 devices. Disable unnecessary devices manually.

How to check how many devices are connected to a hotspot on Android?

On most phones (eg. Xiaomi, Samsung, Realme) the number of connected devices is displayed directly in the notification panel next to the access point icon. iPhone This information can only be seen in the distribution settings (Settings → Tethering), but without detailing the device names.

3. Problems with the ASUS laptop: adapter, drivers, energy saving

If your phone is configured correctly, but your laptop stubbornly refuses to connect to the access point, the culprit is most likely Wi-Fi module or its software. Let's look at it step by step.

3.1. Wi-Fi Hardware Button/Switch

Many models ASUS (For example, VivoBook S14 or ZenBook 13) are equipped with a physical button or key combination to turn off Wi-Fi. Check:

• 🔑 On your keyboard: Look for a key with an antenna icon (usually F2 or Fn + F2). Click it - the adapter may have been disconnected by accident.
• 🔄 On the body: for some models (for example, ASUS ROG Strix) there is a separate switch on the side panel.

3.2. Problems with network adapter drivers

Outdated or corrupted drivers are one of the most common reasons why a laptop won't connect to the network. This is especially true after a Windows update or a system reset. You can check the driver status as follows:

1. Click Win + X and select "Device Manager".
2. Expand the Network Adapters branch and look for a device with a name like Qualcomm Atheros, Intel Wi-Fi 6 or Realtek RTL8xxx.
3. If there is an exclamation mark next to the adapter, right-click on it and select "Update driver."

If automatic update doesn't help, download the driver from official ASUS website, specifying the exact laptop model. For models ROG And TUF Often separate driver versions are required!

Check the physical Wi-Fi switch|Update the network adapter driver|Run Windows troubleshooter|Check your power saving settings-->

3.3. Power saving mode disables Wi-Fi

Windows aggressively saves battery power, and sometimes this causes the Wi-Fi adapter to turn off. To check:

1. Go to Control Panel → Power Options → Change plan settings → Change advanced power settings.
2. Find the "Wireless Adapter Settings" section and set both battery and plugged in states to "Maximum Performance".

It is also useful to disable the feature Random Hardware Addresses (random hardware addresses) that can interfere with smartphone access points:

1. Open Settings → Network & Internet → Wi-Fi → Manage known networks.
2. Select your phone's network (if it has ever been connected to) and disable the "Random hardware addresses" option.

4. IP address conflicts and TCP/IP settings

If a laptop ASUS It sees the phone's network, but when connecting it gives the error "No Internet access" or "Limited", the problem is most likely in IP settingsThe phone, like a router, distributes addresses using the DHCP protocol, but sometimes this process fails.

4.1. Resetting TCP/IP settings

The first thing you should do is reset the Windows network stack. This will clear any stuck settings and restart the services:

netsh int ip reset
netsh winsock reset
ipconfig /flushdns

Run these commands in Command prompt (administrator) and restart your laptop. Then try connecting again.

4.2. Manually assigning an IP address

If automatic IP acquisition does not work, assign a static address manually:

1. Open Control Panel → Network and Sharing Center → Change adapter settings.
2. Right-click on the Wi-Fi adapter, select Properties → Internet Protocol Version 4 (TCP/IPv4) → Properties.
3. Install:
   • IP address: 192.168.43.100 (the last digit can be any number from 2 to 254)
   • Subnet mask: 255.255.255.0
   • Default gateway: 192.168.43.1 (standard phone address as a router)
   • DNS: 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare)

4.3. Conflict with antivirus or firewall

Some antiviruses (for example, Kaspersky, Avast) block "suspicious" networks, which include smartphone hotspots. Temporarily disable your antivirus and Windows Firewall, then try connecting again. If that works, add your phone's network to the exceptions.

⚠️ Attention: If you are using a corporate laptop with pre-installed software (e.g. Cisco AnyConnect or FortiClient), it may block connections to "untrusted" networks. Contact your IT administrator for permission.

5. Wi-Fi Protocol Compatibility: Table and Solutions

Laptops ASUS Different models of different years support different Wi-Fi standards. If the phone is sharing internet using a protocol that the laptop adapter doesn't support, the connection will be impossible. Below is a compatibility table:

If your laptop model is older than 2017 and your phone is new (for example, Samsung Galaxy S23 with Wi-Fi 6E), try:

• 📱 On your phone: Force compatibility mode to work with 802.11n (usually in the access point settings there is an option “Max. compatibility” or “Legacy Mode”).
• 💻 On a laptop: Update your Wi-Fi adapter driver to the latest version (even if Windows says there is no update available).

6. Alternative connection methods if Wi-Fi doesn't work

If all attempts to connect via Wi-Fi fail, consider alternative options for distributing the Internet from your phone to your laptop. ASUS:

6.1. USB cable (USB tethering)

The most stable method, which works even with Wi-Fi outages, is to connect your phone to your laptop with a cable, then:

• 📱 On Android: Settings → Hotspot & Tethering → USB Tethering.
• 🍎 On iPhone: Settings → General → Tethering & Personal Hotspot → Allow Others (You may be asked to confirm that you trust the computer).

The laptop will automatically receive the Internet via Ethernet adapter (in device manager it may appear as Remote NDIS).

6.2. Bluetooth modem

A slower but more reliable method. First, pair the devices:

1. On the laptop: Settings → Devices → Bluetooth → Add a device.
2. On your phone: Turn on Bluetooth and confirm pairing.
3. On your phone: turn it on Bluetooth modem in the access point settings.

The speed will be limited to ~3–5 Mbps, but this is enough for email or instant messaging.

6.3. Hotspot via third-party applications

If standard Wi-Fi sharing is glitchy, try apps like PdaNet+ (Android) or MyWi (iPhone). They bypass system limitations and sometimes work more reliably than built-in functions. Keep in mind that for iPhone Jailbreak may be required.

⚠️ Attention: when using USB tethering on Windows 11 Sometimes an "Unidentified Device" error appears in the Device Manager. In this case, download the driver. RNDIS from the phone manufacturer's website (for example, for Samsung — Samsung support).

7. When to contact service: hardware faults

If none of the above worked, the problem may be hardware related. Here are the signs that your laptop is ASUS repairs required:

• 🔌 The laptop doesn't see it any Wi-Fi networks (including home routers).
• 🔥 In the Device Manager, the adapter is displayed as "Unknown device" or is missing altogether.
• ⚡ When connecting to the phone's hotspot, the laptop turns off or restarts.
• 📡 The Wi-Fi signal is extremely weak (1–2 bars), even if the phone is nearby.

Typical faults:

1. Wi-Fi antenna failure: A common problem after dropping or disassembling a laptop. The antennas are connected to the adapter via thin cables that are easily damaged.
2. Wi-Fi module failure: For example, after a power surge or overheating. In this case, the adapter may be detected in the system but not connect to the network.
3. Problems with the southbridge (for older models): Controls USB and network controllers. Requires soldering or motherboard replacement.

Repair cost:

• Wi-Fi module replacement: from 1,500 to 4,000 ₽ (depending on the adapter model).
• Antenna soldering: from 2,000 ₽.

FAQ: Frequently asked questions about connecting ASUS to your phone's Wi-Fi

❓ My laptop sees my phone's network, but when I connect, it says "Unable to connect to this network." What's wrong?

This error occurs due to:

1. Incorrect password: check the case of the characters (upper/lower case letters).
2. IP conflict: Try setting the IP address manually (section 4.2).
3. Antivirus blocking: Temporarily disable protection and try connecting again.

If nothing helps, reset the network settings on your laptop: Settings → Network & Internet → Status → Network reset.

❓ My phone shares the internet, but my ASUS laptop doesn't allow access to websites (the "Limited" icon appears). How can I fix this?

This is a classic problem with DNSSolutions:

• 🔄 Restart your phone (sometimes the DHCP server freezes).
• 📡 Manually enter DNS on your laptop: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
• 🛠️ Disable IPv6 in the connection properties (if it is enabled).

If you use a VPN on your phone, disable it—it may block traffic for connected devices.

❓ Is it possible to connect an ASUS laptop to an iPhone if the phone doesn't have a SIM card?
