  2. Navigate to Network & Internet: In the left sidebar, click on “Network & Internet,” then scroll to find the “Mobile hotspot” option.
  3. Toggle the Hotspot On: Under the Mobile hotspot section, toggle the switch to “On.” If this is your first time, you’ll need to configure a few settings.
  4. Set Network Name and Password: Click “Edit” to customize the network name (SSID) and password. Choose a strong password with a mix of letters, numbers, and symbols to enhance security.
  5. Select Connection Source: Use the dropdown menu to choose which internet connection to share—Ethernet or Wi-Fi. If your PC is connected via Ethernet, this often provides a more stable hotspot.
  6. Connect Devices: On your other devices, search for the newly created Wi-Fi network, enter the password, and connect.

According to Microsoft’s official documentation, up to eight devices can connect to a Windows 11 hotspot simultaneously, though performance may vary based on hardware and bandwidth. I cross-checked this with TechRadar, which confirms the eight-device limit but notes that real-world performance often dips with more than four or five connections.

Verifying Hardware Compatibility

Not all PCs can act as hotspots out of the box. To confirm compatibility, you can check if your wireless adapter supports Hosted Network functionality. Open Command Prompt as an administrator and type netsh wlan show drivers. Look for the line “Hosted network supported: Yes.” If it says “No,” you might need to update your drivers or invest in a compatible USB Wi-Fi adapter. I verified this method through Microsoft’s support forums and a detailed guide on PCMag, ensuring its accuracy for troubleshooting.

If your hardware isn’t compatible, don’t worry—affordable USB Wi-Fi adapters with hotspot capabilities are widely available. Brands like TP-Link and Netgear offer reliable options under $20, making this an accessible fix for most users.

Practical Applications for Windows 11 Hotspot Users

The ability to create a Wi-Fi connection from your PC opens up a range of possibilities for both personal and professional use. Let’s explore some of the most compelling use cases:

  • Travel Companion: When traveling, public Wi-Fi networks are often unsecured or unreliable. Using your Windows 11 laptop as a hotspot allows you to create a private, secure network for your devices, reducing the risk of data theft.
  • Remote Work Setup: In temporary workspaces without dedicated Wi-Fi, a hotspot can bridge the gap. Share your PC’s Ethernet connection with a team during a client meeting or conference.
  • Gaming and Streaming: For gamers or streamers, a stable connection is non-negotiable. If your PC is wired to a router, turning it into a hotspot can provide low-latency access for consoles or mobile devices.

These applications highlight the versatility of this feature, making it a must-know for any Windows user looking to optimize their network setup.

Security Considerations for Wi-Fi Sharing

While the convenience of a mobile hotspot is undeniable, it comes with significant security risks. Broadcasting a Wi-Fi signal from your PC essentially turns it into a public access point, potentially exposing your system to unauthorized access or malicious attacks. Let’s break down the key risks and how to mitigate them.

Risks of Using a Mobile Hotspot

  • Unauthorized Access: Without a strong password, anyone within range can connect to your network, potentially accessing shared files or snooping on traffic.
  • Data Interception: Unencrypted connections make it easier for hackers to intercept sensitive information, especially on public networks.
  • Resource Drain: Multiple connected devices can slow down your PC and consume significant bandwidth, impacting performance.

Best Practices for Hotspot Security

  • Use a Strong Password: As mentioned earlier, set a complex password with at least 12 characters, mixing uppercase, lowercase, numbers, and symbols.
  • Enable WPA3 Encryption: Windows 11 supports WPA3, the latest Wi-Fi security protocol. Ensure your hotspot uses this for maximum protection. I confirmed with ZDNet that WPA3 is supported on Windows 11 with compatible hardware.
  • Limit Connected Devices: Monitor connected devices through the Mobile Hotspot settings and disconnect unfamiliar ones immediately.
  • Disable File Sharing: Turn off network discovery and file sharing in Windows settings to prevent unauthorized access to your data.
  • Use a VPN: For an added layer of security, route your hotspot traffic through a reputable VPN service to encrypt data transmission.

Microsoft’s support page emphasizes that hotspot security largely depends on user configuration, a point echoed by cybersecurity experts at CNET. Taking these precautions can significantly reduce risks, making your Windows 11 hotspot both convenient and safe.

Performance Impacts and Bandwidth Management

Turning your PC into a wireless access point isn’t without trade-offs.
