:high_voltage: Your Laptop Has a Router Built In — Plus 5 Free Tools to Supercharge It

Your laptop already has a router hiding inside it. Here’s how to wake it up.

Got one internet connection and five devices staring at you? Hotel charging per device? Ethernet cable but no Wi-Fi? Your Windows laptop can fix all of this — no extra hardware, no networking degree.

⚡ Method 1 — Windows Built-In Hotspot (No Install, Already on Your PC)

Windows 10/11 has a mobile hotspot baked in. Most people don’t know it exists.

Setup — 4 clicks:

  1. Settings → Network & Internet → Mobile Hotspot
  2. Pick your internet source (Wi-Fi, Ethernet, or cellular)
  3. Hit Edit — set your hotspot name + password
  4. Flip the toggle ON

That’s it. Your phone, tablet, or friend’s laptop can now connect to your PC like it’s a router.

What It Does What It Doesn’t
Shares Wi-Fi, Ethernet, or cellular No ad blocking
WPA2 encrypted by default No bridging mode (consoles may struggle)
Supports Wi-Fi + Bluetooth sharing No repeater/range extender
Up to 8 devices No custom SSID prefix control
Zero install, zero bloat No bandwidth monitoring per device

Best for: Quick sharing, travel, hotel Wi-Fi splitting. If you just need devices online — this is enough.

🔧 Method 2 — Connectify Hotspot (More Control, Free Version Available)

Connectify Hotspot is a virtual router app that’s been around since 2009. 150M+ downloads. Does more than the built-in option — but the free version has limits.

Setup:

  1. Download from connectify.me/download
  2. Install → launch → pick internet source
  3. Name your hotspot + set password
  4. Hit Start Hotspot
Feature Free Pro ($19.98+) Max ($34.98+)

Bridging mode (consoles, NAT fix) :cross_mark: :cross_mark: :white_check_mark:
VPN sharing over hotspot :cross_mark: :white_check_mark: :white_check_mark:

Honest take: The free version works for basic sharing but nags you to upgrade constantly. For most people, the Windows built-in hotspot does the same thing without the nag screens.

Where Connectify actually earns it: Ad blocking on connected devices (even in-app ads on phones), device-level bandwidth monitoring, and — if you pay — VPN sharing and bridging mode for game consoles.

🆓 Free Alternatives — No Nag Screens, No Paywalls

If Connectify’s upgrade popups annoy you, these are 100% free:

Tool What Makes It Different Link

⚠️ Heads Up — Common Issues + Fixes
Problem Fix
Hotspot won’t start Run as admin. Update Wi-Fi drivers. Restart “Internet Connection Sharing” service.
Devices connect but no internet Check firewall rules. Disable VPN on host (unless sharing VPN intentionally).
Slow speeds on connected devices Move host laptop closer. Reduce connected device count. Close bandwidth-heavy apps on host.
“Connectify-” prefix stuck Free version limitation — upgrade to Pro, or just use Windows built-in instead.
Hotspot disappears after sleep Disable sleep/hibernation while sharing, or enable “power saving off” for Wi-Fi adapter.

Your laptop was a router this whole time. It was just waiting for you to ask.

Instead of turning it into a hotspot, use it as a homeserver.
