My laptop won't connect to Wi-Fi from my phone: A full breakdown of the causes and solutions.

You are trying to share the Internet from your phone to your laptop via mobile hotspot, but the devices stubbornly fail to see each other—or the connection keeps dropping? This problem is familiar to millions of users, and its causes lie in both smartphone settings and laptop configuration. In 80% of cases, the problem can be resolved in 5–10 minutes without a trip to a service center, but this requires a precise diagnosis of the source of the problem.

In this article we will look at all possible scenarios: from banal errors in the settings Android/iOS before driver conflicts Wi-Fi adapter on a laptop. You will learn how to check network operating mode (2.4 GHz vs 5 GHz), why Some laptop models refuse to connect to access points with WPA3 encryption., and what to do if your phone "sees" your laptop, but the internet isn't working. For your convenience, we've compiled step-by-step instructions with screenshots and a device compatibility chart.

Be warned in advance: if you use old version of Windows (For example, Windows 7) or phone with Android 8.0 and belowSome solutions may not work due to security protocol limitations. In this case, alternative connection methods, which we've also described, will be useful.

1. Checking the basic hotspot settings on your phone

The first thing to do is to make sure that the access point is enabled correctly and its parameters are compatible with the laptop. Errors at this stage occur in 60% of cases, especially among users setting up internet sharing for the first time.

On Android (version 9.0 and above) the path to the hotspot settings looks like this: Settings → Network & Internet → Hotspot & Tethering → Hotspot Settings. Check here:

• 🔄 Network name (SSID): must contain only Latin characters and numbers (no spaces or special characters). Example of a valid name: MyHotspot_5G.
• 🔒 Security type: the best option is WPA2-PSK (some laptops do not support WPA3).
• 📶 Frequency range: If your laptop is older than 2018, choose 2.4 GHz (5GHz may not be supported).
• 🔄 Password: minimum 8 characters, without Cyrillic. Example: 12345678Qw.

On iPhone (iOS 14+) another way: Settings → Personal Hotspot → Wi-Fi PasswordYou can't change the network name here (it's always iPhone [your name]), but it is possible:

• 🔒 Change your password (the default is often a simple code like 12345678, which conflicts with some adapters).
• 📶 Enable mode Maximum compatibility (if it is available in your iOS version) so that the hotspot operates in the 2.4 GHz range.

If the laptop still won't connect after making these changes, reboot both devices. Sometimes the issue is caused by an IP address conflict, which can be resolved with a simple reboot.

2. Diagnosing the Wi-Fi adapter on a laptop

If the phone distributes the Internet, but the laptop does not see the network or displays an error "Unable to connect", the problem may lie in adapter drivers or its settings. Let's start with a simple check:

1. Click Win + X and select device Manager.
2. Expand the tab Network adapters.
3. Find the device with the names Wireless, Wi-Fi or 802.11 (For example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA9377).
4. If the icon next to the adapter is lit exclamation mark, the driver is not working properly.

Update the driver manually:

1. Right-click on the adapter → Update driver → Search for drivers on this computer.
2. Select Select a driver from the list of available ones and install the latest version (if it is on the list).

If the update does not help, download the driver from the laptop manufacturer's website (for example, Lenovo Support, HP Customer Support) or directly from the adapter manufacturer (Intel, Qualcomm, Broadcom). Please indicate the exact model of your laptop and adapter!

Is the adapter enabled in Device Manager?|Are there any driver updates?|Have you tried rolling back the driver to a previous version?|Have you checked the adapter's power settings?-->

Also check power settings:

1. IN Device Manager Right-click on the adapter → Properties → tab Power management.
2. Uncheck the box Allow the computer to turn off this device to save power.

3. Frequency conflicts: 2.4 GHz vs. 5 GHz

One of the most common causes of problems is Wi-Fi band incompatibilityMany modern phones distribute Internet in the range by default. 5 GHz, which provides high speeds but has a smaller coverage area and is not supported by older laptops.

How to check this:

• 📱 On Android: in the access point settings, find the item Range or FrequencyIf there is a choice between 2.4 GHz And 5 GHz, choose the first one.
• 🍎 On iPhone: iOS automatically selects the band, but you can force it to be limited to 2.4 GHz by enabling Maximum compatibility mode (if available in your version).
• 💻 On a laptop: If the adapter supports both bands but the connection fails, try manually selecting the 2.4 GHz network in the Wi-Fi settings.

If your laptop was manufactured before 2016, it likely doesn't support 5 GHz. In this case:

• Use only 2.4 GHz on the phone.
• Make sure that the laptop is Adapter properties (V Device Manager) there is no range limitation.

4. Problems with IP addresses and DHCP

Sometimes the laptop connects to the hotspot, but the internet doesn't work—pages won't open, and there's an exclamation mark next to the Wi-Fi icon. This is a sign IP address conflict or a malfunction DHCP servers (which automatically distributes addresses to devices on the network).

How to fix:

1. On your laptop, open Command line (Win + R → enter cmd → Enter).
2. Enter the commands one by one:

   ipconfig /release
   ipconfig /renew

   This will reset the current IP and request a new one from the phone.

3. If this doesn't help, assign the IP manually:
   1. Open Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings.
   2. Right-click on your Wi-Fi connection → Properties → Internet Protocol version 4 (TCP/IPv4).
   3. Select Use the following IP address and enter:
      • IP address: 192.168.43.100 (or another from the range 192.168.43.x)
      • Subnet mask: 255.255.255.0
      • Default gateway: 192.168.43.1 (standard hotspot address on Android)
      • DNS: 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare DNS)

On iPhone The default gateway address may be different (e.g. 172.20.10.1). Check it in the modem mode settings.

What should I do if the Internet still doesn't work after manually setting up my IP?

Try connecting to a different network (for example, your home Wi-Fi) to check if your antivirus or firewall is blocking the connection. Also, make sure your phone's data plan (mobile data or Wi-Fi, if you're sharing a connection from another network) is enabled.

5. Blocking by antivirus or firewall

Security programs (eg Avast, Kaspersky, Windows Defender) sometimes block connections to "unknown" networks, especially if the access point is being created for the first time. This also applies to the built-in Windows Firewall.

How to check:

• 🛡️ Temporarily disable your antivirus and try connecting again.
• 🔥 Open Windows Firewall (Control Panel → System and Security → Windows Firewall) and check if there are any blocks for your network.
• 🔧 If you use VPN, disable it - some VPN services conflict with Internet distribution via a hotspot.

On Windows 10/11 It's also worth checking the settings public and private network:

1. Open Settings → Network & Internet → Status → Configure adapter settings.
2. Right-click on your Wi-Fi connection → Properties.
3. Make sure the network is marked as Private (Not Publicly available), otherwise Windows may restrict access.

6. Hardware faults and alternative connection methods

If none of the previous methods worked, the problem may be hardware:

• 📡 Laptop Wi-Fi adapter failed (check if the laptop can see other networks).
• 📱 Telephone antenna damaged (try sharing the Internet from another device).
• 🔋 Lack of food: Some phones turn off the hotspot when the battery is low.

Alternative connection methods if Wi-Fi is not working:

1. USB modem: connect your phone to your laptop via cable and turn it on USB modem in your phone settings. This is more reliable than Wi-Fi, but requires a wire.
2. Bluetooth: can be used in conjunction with Wi-Fi Bluetooth connection for internet transmission (slower, but more stable).
3. External adapter: If your laptop's built-in Wi-Fi is broken, buy a USB adapter (e.g. TP-Link TL-WN725N for ~500 ₽).

How to check if my laptop's Wi-Fi adapter is working?

If the laptop doesn't see not a single one network (including your home router), the problem is most likely with the adapter. Check it in Device Manager - If the device is missing or marked with a cross, it requires repair or replacement.

7. Features of specific laptop and phone models

Some devices have unique bugs, which cannot be resolved with standard methods. We've compiled the most common cases:

If your model is not included in the table, search for a solution on the manufacturer's forums (for example, Lenovo Community, Xiaomi Forum) or in RedditUsers often share working workarounds for specific devices.
