Windows 10: Network Bridge Issues after 1903 Update

I had a working Internet Connection Sharing established between my Pdanet USB cellphone tether (usb-c) and my Realtek PCIe GbE Family Controller (feeding out to Asus router). Updating from 1803 to 1903 instantly broke the ICS. Pdanet still shows as shared to the Realtek, but any devices that connect to the Asus router show no internet despite a strong router signal. This has more or less crippled my home internet setup in one update.

Network bridge suddenly stopped working in windows 10

Hi Shantanu,

To isolate your concern, we would like to know how your network bridge is connected? Is it a wireless connection or a wired connection?

In the meantime, we suggest that you set up your network bridge to refresh the adapter and reconnect the other devices. To do this, follow the steps below:

• Add Incoming Connections from the Internet.
• Bridge the two network connections that you want to use.
• Forget the internal network connection (under
  Manage Known Networks).
• Reconnect to your bridge network.
• Restart your computer and check if your concern persists.
  

Let us know if you need further assistance.

 

Network Bridge Stops Working after Creator's Update

I have also found that the Network Bridge has issues in the 1709 Windows Creators Update. Prior to update this setup worked flawlessly. It may have been the Creators Update, or an additional update from Windows Update that caused the issue.

Setup: Intel NIC and Wifi card in Host 1, both with new drivers. Wifi to domain network, 1Gb Ethernet to Host 2, bridged. Host 2 in DHCP.

Symptoms include:

• Mis- or very slow detection of network (stays at "unidentified") when both nics are in the plugged/connected state and bridged. Seems to be random whether the WiFi stays connected when DHCP is used on Host 1. Using static IP keeps the Wifi connected on
  Host 1.
• Pings to local (DNS) and remote servers intermittent on Host 1 after positive detection of domain network. Network task tray icon shows No Internet alert intermittently in conjunction with ping loss. Maybe 10-20 sec of ping replies, then none for a period.
  This suggests maybe a spanning tree detection algorithm is blocking at layer 2.
• IPV4 Route Table doesn't seem to change between working and non-working state, suggesting the problem is not in the IP stack.
• Removing bridge removes all symptoms on Host 1, and all connectivity on Host 2.
• Disabling/re-enabling both bridged NICs on Host 1, enough times and in the correct order, seems to fool the system, or get it a state machine in the proper state, and will finally get the detection algorithm to 'hook-up', but ONLY until the next reboot.

 

Unable to bridge adapters

Hi Damo,

Thank you for posting the query on Microsoft Community. I am glad to assist you on this.

A network bridge is software or hardware that connects two or more networks so that they can communicate. You can create only one network bridge on a computer, but one bridge can handle any number of network connections.

This issue may occur due to corrupt network drivers or settings.

Try the method below and check.

Method 1:

I would suggest you to run network adapter troubleshooter and check if it helps.

a. Type troubleshooting in the search box in taskbar.

b. Click troubleshooting in the search results.

c. Click "View all" and then click "Network Adapter".

d. Click "Next" and follow on-screen instructions.

Method 2:

If issue persists uninstall the network adapter drivers and re-install the same and check if that fixes the issue.

Follow the steps to uninstall the network adapter drivers.

a. Press Windows Key + X and then click
Device Manager.

b. Expand Network adapters.

c. Right on the Network Adapter and select uninstall.

e. Restart the computer.


Once completed, restart your computer. Your network adapter Drivers will automatically install.

To creating a network bridge, follow the steps below:

• In search type Network and Sharing Center and enter.
• Now you can see different network connection. Hold down the Ctrl key and select each network connection that you want to add to the bridge.
• Right-click one of the selected network connections, and then click Bridge Connections.
  If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

Kindly let us know if you need any further assistance with Windows. We are glad to assist you.

Thank you.
