Create a Portable Hotspot from Your Lenovo Laptop (Windows & Linux)Sharing your Lenovo laptop’s internet connection as a portable Wi‑Fi hotspot can be a lifesaver — whether you need to get multiple devices online, extend a wired connection, or provide internet to friends while traveling. This guide covers reliable methods for both Windows and Linux, troubleshooting tips, security best practices, and performance suggestions so your Lenovo becomes a stable, portable hotspot.

Which method to choose?

Choose based on your operating system and technical comfort:

  • Windows: built‑in Mobile Hotspot (easiest) or Command Prompt/PowerShell for finer control.
  • Linux: Network Manager GUI (user‑friendly) or hostapd + dnsmasq (more robust, for advanced users).

Windows: Using Built‑in Mobile Hotspot (Windows 10 / 11)

This is the simplest method and works on most modern Lenovo laptops with a functional Wi‑Fi adapter.

  1. Open Settings → Network & Internet → Mobile hotspot.
  2. Under “Share my Internet connection from,” choose the source (Wi‑Fi, Ethernet, or cellular).
  3. Toggle Mobile hotspot to On.
  4. Click Edit to change Network name (SSID) and Network password. Use WPA2/WPA3 if available.
  5. Optionally, set “Share over” to Wi‑Fi or Bluetooth. Choose Wi‑Fi for standard hotspot use.
  6. Connect your devices using the SSID and password you set.

Tips:

  • If your laptop is using a wireless connection and your Wi‑Fi adapter doesn’t support concurrent AP and client modes, Windows will create a virtual adapter (Microsoft Hosted Network / Mobile Hotspot) if supported. If not, use Ethernet as the source or try the command‑line method below.
  • To limit data use, enable “Power saving” or turn off hotspot when not in use.

Windows: Command Prompt / PowerShell method (if Mobile Hotspot not available)

  1. Open Command Prompt as Administrator.
  2. Check if your adapter supports hosted network: 
    
netsh wlan show drivers

    Look for: Hosted network supported: Yes.

  3. Set up the hosted network: 
    
netsh wlan set hostednetwork mode=allow ssid=LenovoHotspot key=YourPassword123
  4. Start the hosted network: 
    
netsh wlan start hostednetwork
  5. To share an existing internet connection, open Control Panel → Network and Sharing Center → Change adapter settings. Right‑click the adapter with internet (Ethernet, VPN, etc.) → Properties → Sharing tab → check “Allow other network users to connect” and choose the virtual adapter (usually named “Local Area Connection* X” or similar).
  6. To stop: 
    
netsh wlan stop hostednetwork

Notes:

  • If “Hosted network supported” is No, your Wi‑Fi card’s driver may not support it. Updating drivers or using third‑party apps (Connectify, Virtual Router) can help, but prefer built‑in options for security.

Linux: Using Network Manager (GUI) — Ubuntu, Mint, Fedora, etc.

Many Linux distributions provide an easy GUI route through Network Manager to create a hotspot.

  1. Click the network indicator (top bar or system tray) → Wi‑Fi Settings.
  2. Choose “Use as Hotspot” or “Create New Wi‑Fi Network” (wording varies).
  3. Set SSID, choose security (WPA2 Personal recommended), and password.
  4. Start the hotspot — Network Manager will configure the wireless interface and enable sharing.
  5. Connect devices using the SSID and password.

If the GUI option is missing, you may need to enable sharing on your connection or install additional packages (network-manager-applet).

Linux: Advanced — hostapd + dnsmasq (robust, configurable)

This method gives full control, ideal if you need performance, bridging, or advanced DHCP/DNS options.

Install:

sudo apt update sudo apt install hostapd dnsmasq

Basic hostapd config (/etc/hostapd/hostapd.conf):

interface=wlan0 driver=nl80211 ssid=LenovoHotspot hw_mode=g channel=6 wpa=2 wpa_passphrase=YourPassword123 wpa_key_mgmt=WPA-PSK rsn_pairwise=CCMP

Edit /etc/default/hostapd to point to config:

DAEMON_CONF="/etc/hostapd/hostapd.conf"

Configure dnsmasq for DHCP (/etc/dnsmasq.conf):

interface=wlan0 dhcp-range=192.168.50.10,192.168.50.100,12h

Enable IP forwarding and NAT (example using iptables):

sudo sysctl -w net.ipv4.ip_forward=1 sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Replace wlan0 (wireless) and eth0 (internet) with your interface names. Start services:

sudo systemctl start hostapd sudo systemctl start dnsmasq

Notes:

  • Some Wi‑Fi adapters don’t support AP mode. Check with: 
    
iw list

    Look for “AP” under Supported interface modes.

  • For persistent iptables rules, add them to a script or use nftables/firewalld depending on your distro.

Common troubleshooting

  • No hotspot option / “Hosted network supported: No”: update Wi‑Fi drivers, check adapter supports AP mode, or use Ethernet for source.
  • Devices can’t connect: confirm SSID/password, ensure AP mode supported, check wireless channel conflicts.
  • No internet on connected devices: enable Internet Connection Sharing (Windows) or configure NAT and IP forwarding (Linux).
  • Slow speeds: try a different channel, switch between 2.4GHz and 5GHz (if supported), or reduce number of connected devices.
  • Hotspot stops after sleep: change power settings to prevent Wi‑Fi adapter from sleeping.

Security & best practices

  • Use WPA2 or WPA3 encryption with a strong password (12+ random characters).
  • Change SSID and password regularly if used in public settings.
  • Limit connected devices when possible.
  • Monitor data use if your source is a metered connection.
  • Keep OS and Wi‑Fi drivers updated.

Performance tips for Lenovo laptops

  • Use 5GHz band if available for less interference and higher throughput.
  • Connect the laptop to the internet source via Ethernet when possible to avoid relying on a Wi‑Fi client adapter.
  • Close background apps that use bandwidth; enable QoS on router if sharing wired source.
  • Use a powered USB‑C dock or keep the laptop plugged in to avoid power management throttling the Wi‑Fi adapter.

Example use cases

  • Coffee shop or small meeting: quick Wi‑Fi for multiple devices from a wired connection.
  • Travel: share a hotel wired or limited Wi‑Fi room connection with your devices.
  • Development/testing: create an isolated local network for device testing.

If you want, I can: provide step‑by‑step screenshots for Windows or Ubuntu, generate a hostapd/dnsmasq config tailored to your exact interface names, or walk through driver update commands for your Lenovo model — tell me your OS and model.
