How to Connect a Laptop to a PC via Wi-Fi: A Complete Guide with Settings and Tips

Connecting a laptop to a desktop PC wirelessly opens up a wealth of possibilities: from transferring files without flash drives to remote desktop control or internet sharing. However, many users encounter problems setting up this connection—the network isn't detected, the devices don't see each other, or the data transfer speed leaves much to be desired.

In this article we will look at three main connection methods - through access point, local network And remote desktop — taking into account the specifics Windows 10/11 And macOSYou'll learn how to properly set up a network, avoid common mistakes, and optimize your connection for maximum speed. And if you need to do more than just connect devices, but, for example, Use your laptop as a second monitor for your PC without additional wires, we will tell you how to do this with minimal costs.

1. Preparing devices: what to check before connecting

Before you begin setup, make sure both devices meet the minimum requirements. This will save you time and avoid frustration.

Hardware and software requirements:

• 🖥️ Desktop PC: must have Wi-Fi adapter (built-in or external USB). If you don't have one, you'll need to purchase an adapter that supports the standard. 802.11ac (for speeds from 433 Mbps) or Wi-Fi 6 (for 9.6 Gbps). Check the model in Device Manager.
• 💻 Laptop: Any modern laptop (even a budget one) is equipped with a Wi-Fi module. The main thing is to update the drivers via device Manager or the manufacturer's website (Intel, Qualcomm, Broadcom).
• 🌐 Router (optional): If you plan to connect through a router, make sure it supports dual range (2.4 and 5 GHz). A router is not required for a direct connection (ad-hoc).
• 🔄 Operating system: Windows 10/11 or macOS 10.15+On . Windows 7/8 There may be problems with drivers for modern adapters.

What to check in the settings:

• 🔒 Firewall: temporarily disable it on both devices (in Control Panel → Windows Defender Firewall) to prevent connection blocking. After configuration, you can return to the default rules.
• 📡 Network mode: if you use public network (for example, in a cafe), switch to Private in the Wi-Fi settings. Otherwise, Windows will block file sharing.
• 🔄 IP addresses: By default, devices should receive IP addresses automatically (DHCP). If you previously assigned static addresses, reset the settings in IPv4 Properties.

⚠️ Attention: If your PC is connected to the Internet via PPPoE (entering your login/password every time you turn it on) won't allow you to create an access point directly from it. First, set up internet sharing through the router.

2. Method 1: Connecting via an access point (Hotspot)

The most universal method is to turn one of the computers (usually a PC) into a hotspot that the laptop can connect to. This will allow you to not only share files but also share internet from the PC to the laptop.

Instructions for Windows 10/11:

1. Open Command prompt as administrator (click Win + X → Terminal (Administrator)).
2. Enter the command to check Wi-Fi distribution support:

   netsh wlan show drivers

   Find the line Hosted network support - there should be Yes.

3. Create a network named MyPC_Hotspot and password 12345678 (replace with your own):

   netsh wlan set hostednetwork mode=allow ssid=MyPC_Hotspot key=12345678

4. Start the access point:

   netsh wlan start hostednetwork

5. Allow Internet Sharing:
   1. Open Control Panel → Network and Sharing Center → Change adapter settings.
   2. Find the connection through which the PC receives the Internet (for example, Ethernet), right-click → Properties → tab Access.
   3. Check the box Allow other network users to share your Internet connection and select the created network (Local Area Connection* X).

For macOS (distribution from MacBook):

1. Open System Preferences → Sharing.
2. Select Public Internet → in the field General connection please indicate Ethernet (or Wi-Fi, if the Internet comes over the air).
3. IN For computers using mark Wi-Fi.
4. Click Wi-Fi settings, set the network name (SSID) and password, then enable sharing.

⚠️ Attention: On some motherboards (eg. ASUS ROG or MSI MAG) the built-in Wi-Fi module may conflict with the drivers when distributing the network. If the command netsh wlan start hostednetwork gives an error, update the adapter driver manually from the manufacturer's website.

3. Method 2: Direct connection (Ad-Hoc) without a router

If you don't have a router, you can create a direct connection between your PC and laptop in wireless mode. ad-hocThis method is suitable for transferring files or playing games over a local network, but does not allow Internet sharing.

Setting up on Windows:

1. Open Control Panel → Network and Sharing Center → Set up a new connection.
2. Select Setting up a wireless computer-to-computer network (V Windows 11 This item may be missing - use netsh as in method 1).
3. Set the network name (SSID), security type WPA2-Personal and password.
4. Connect your laptop to the created network manually (you may need to specify IP address manually, for example, 192.168.1.2 for laptop and 192.168.1.1 for PC).

Setup on macOS:

1. Open Create a network in the Wi-Fi menu bar (hold Option and click on the Wi-Fi icon).
2. Select Create a network, specify the name and channel (for example, 11 for 2.4 GHz).
3. On your laptop, connect to the created network. To share files, enable File sharing V System settings.

How to check the connection:

• 📌 On Windows open Command line and enter:

  ping 192.168.1.2

  (Replace the IP address with your laptop's address.) If packets arrive without loss, the connection is working.

• 📌 On macOS use Terminal:

  ping 192.168.1.1

⚠️ Attention: In mode ad-hoc maximum speed is limited 54 Mbps (standard 802.11g). For transferring large files (>1 GB), it is better to use an access point or cable.

4. Method 3: Remote Desktop (RDP) and Sharing

If you need to not just link devices, but control a PC from a laptop (for example, to work with programs or games), configure remote desktopThis also works over Wi-Fi, but requires a stable connection.

Setting up RDP on Windows:

1. On PC (which you will control):
   1. Open Settings → System → Remote Desktop.
   2. Turn on the slider Enable Remote Desktop.
   3. Add a user who is allowed access (default is the current administrator).
   4. Remember the PC name (displayed in the same window, for example, DESKTOP-ABC123).
2. On laptop:
   1. In the search bar, enter Remote Desktop and launch the application.
   2. In the field Computer Enter the PC name (or its local IP, for example, 192.168.1.100).
   3. Enter your PC account login and password.

RDP alternatives:

• 🖥️ TeamViewer or AnyDesk: do not require network settings, but depend on the Internet speed.
• 🎮 Steam Link: for streaming games from a PC to a laptop over a local network.
• 📁 Shared folders: If you only need file access, set up folder sharing in Properties → Access (allow read/write access for user Everyone).

5. Speed ​​optimization and troubleshooting

Even if you have a connection, Wi-Fi speeds can be disappointing. Here's how to improve them:

Reasons for low speed and solutions:

• 📶 2.4 GHz Channel Congestion: switch to 5 GHz in the access point settings (command netsh wlan set hostednetwork mode=allow ssid=Name key=Password channel=36, Where 36 — 5 GHz channel).
• 🔌 Outdated Wi-Fi standard: if the adapter only supports 802.11n, maximum speed is 150 Mbps. Upgrade your hardware to Wi-Fi 5 (802.11ac) or Wi-Fi 6.
• 📡 Interference from other networks: use programs like Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) to select a free channel.
• 🛡️ Encryption: WPA3 It's safer, but may reduce speed on older devices. For maximum performance, use WPA2-AES.

Speed ​​test between devices:

1. Download the utility iPerf3 on both devices (official website).
2. On PC start the server:

   iperf3 -s

3. On laptop run the client:

   iperf3 -c 192.168.1.1

   (replace IP with PC address).

4. Compare the result with the table:

6. Security: How to secure your connection

An open access point or a weak password can be a juicy target for hackers. Follow these rules:

Minimum safety requirements:

• 🔐 Password: Use a combination of 12+ characters with numbers, capital letters and special characters (e.g. WiFi-PC_2026!K). Avoid simple sequences like 12345678.
• 🔒 Encryption type: only WPA2-PSK (AES) or WPA3. WEP And WPA-TKIP hacked in minutes.
• 📛 Network Name (SSID): Do not use personal information (eg Ivanov_PC). A neutral name like Office-LAN-2.
• 🚫 Hidden network: disable the option Hide SSID - this does not increase security, but only complicates the connection.

Additional measures:

• 🛡️ MAC filtering: In your router settings (if you use one), whitelist the MAC addresses of only your devices. Find them using ipconfig /all (Windows) or ifconfig (macOS).
• 🔄 Guest network: If you share the Internet through a router, create a separate guest network for the laptop with limited rights.
• 📡 Updates: Regularly check for updates of Wi-Fi adapter drivers and router firmware (especially critical for TP-Link And ASUS).

⚠️ Attention: If you are setting up a connection in a public place (such as a coworking space), never use the mode ad-hoc — it's easy to intercept. Give preference to a secure access point with WPA3.

7. Alternative methods: when Wi-Fi isn't suitable

If your wireless connection is unstable, consider alternatives:

Connection options:

• 🔌 Powerline adapters: They transmit data over electrical wiring (speeds up to 1 Gbps). They're suitable if the router is far away and running cables is inconvenient. Popular models: TP-Link AV1000, Devolo Magic 2.
• 📶 USB Wi-Fi adapter with external antenna: If the built-in module is weak, an external adapter (for example, ASUS USB-AC68) will increase the range and speed.
• 🖥️ Mobile hotspot: if both devices support USB-Tethering, you can distribute the Internet via a smartphone (but this will create additional latency).
• 🔗 Direct cable connection: through Ethernet or USB-C (if ports support Alternate Mode). Speed ​​up to 10 Gbps, without delays.

When to choose an alternative:

• 🎮 For online games (For example, CS2 or Fortnite): Even a 30ms Wi-Fi latency can be critical. Use a cable.
• 🎥 For 4K video streaming: Wi-Fi 5 will handle a maximum of 4K@30fps, but for 60fps you need Wi-Fi 6 or wire.
• 📦 For regular transfer of large files (>10 GB): via cable it will be 5-10 times faster.
