To create a network bridge in Windows, open Network Connections via ncpa.cpl, select the desired adapters (e.g., Ethernet and Wi-Fi) while holding Ctrl, right-click, and choose Bridge Connections, ensuring no adapter is already in a bridge or using Internet Connection Sharing (ICS). 2. Wait for Windows to create the Network Bridge, which will appear as a new interface, merging the selected adapters into a single network segment that shares internet connectivity, uses DHCP for IP assignment, and enables device communication across both networks. 3. Ensure the internet-providing adapter (e.g., Wi-Fi) is included in the bridge, verify firewall settings allow bridged traffic, avoid static IP conflicts by using DHCP, and resolve issues like bridge creation errors by disabling ICS, updating drivers, or restarting adapters, noting that administrative rights are required and the bridge can be deleted when no longer needed.

Creating a network bridge between two adapters in Windows allows you to connect multiple networks (like Ethernet and Wi-Fi) so devices on one can communicate with devices on the other, effectively merging them into a single network segment. This is useful for sharing an internet connection or connecting wired devices to a wireless network.

Here’s how to set it up:

1. Open Network Connections

• Press Windows R, type ncpa.cpl, and press Enter.
• This opens the Network Connections window, showing all your network adapters (e.g., Ethernet, Wi-Fi).

2. Select Adapters to Bridge

• Hold down the Ctrl key and click to select the two adapters you want to bridge (e.g., Ethernet and Wi-Fi).
• Right-click on one of the selected adapters.
• Choose Bridge Connections from the context menu.

?? Note: You can't bridge an adapter that's already part of another bridge or using certain features like Internet Connection Sharing (ICS). Disable ICS first if needed.

3. Wait for the Bridge to Be Created

• Windows will create a Network Bridge interface.
• A new item labeled "Network Bridge" will appear in the list.
• Both selected adapters will now show under the bridge and lose their individual network icons briefly.

The bridged connection will:

• Share the internet connection from one adapter (e.g., Wi-Fi) with devices connected via the other (e.g., Ethernet).
• Assign IP addresses via DHCP (usually from the main network).
• Allow devices on both networks to see each other.

Important Notes & Tips

• Internet Source Matters: The adapter providing internet (e.g., Wi-Fi connected to a router) should be included in the bridge. The bridge itself doesn’t route traffic automatically — it relies on the host network setup.

  

• Performance Considerations:

  • Bridging Wi-Fi and Ethernet can work, but performance may vary depending on the Wi-Fi signal and network load.
  • Some Wi-Fi adapters don’t support bridging well due to driver limitations.

• Firewall & Security: Ensure your firewall allows communication across the bridge. Some security software may block traffic between bridged networks.

• Static IP Conflicts: Avoid assigning static IPs that conflict with the network’s DHCP range. Let the router handle IP assignment when possible.

• Administrative Rights Required: You must be logged in as an administrator to create a bridge.

Troubleshooting Common Issues

• "An error occurred while creating the bridge":

  • Disable Internet Connection Sharing (ICS) if enabled.
  • Restart the network adapters.
  • Update network drivers.

• No internet on bridged devices:

  • Check which adapter has internet access — the one with internet should be in the bridge.
  • Restart the bridge: delete it, then recreate it.

• Can’t see devices across the bridge:

  • Make sure all devices are on the same subnet.
  • Check network discovery and firewall settings.

Once created, the bridge requires little maintenance. If you no longer need it, just right-click the Network Bridge and select Delete. The individual adapters will return to normal operation.

Basically, Windows handles the rest — no extra software or configuration needed for basic use.
