I want to Bridge my Windows 7 laptop's wireless and wired adapters. I just select my ethernet and WIFI adapter, and choose create bridge.

However when plugging in ethernet cable, instantly my WIFI disconnects. How to prevent this?

I have a HP nx6310 laptop with latest WIFI drivers.

I found this on another website and it worked for me:

"When more than one network connection is available, Windows uses the one with the lowest metric value. By default, it automatically assigns a metric value based on the network connection's rated speed. See An explanation of the Automatic Metric feature for Internet Protocol routes .

To force Windows to use a specific network connection, assign a metric value to each one, giving the lowest value to the desired connection:

  1. Open the Network Connections folder (Start > Run > ncpa.cpl)
  2. Right click the desired connection.
  3. Click Properties > Internet Protocol Version 4.
  4. Click Properties > Advanced.
  5. Un-check "Automatic metric".
  6. Enter a number between 1 and 9999 for the "Interface metric"."

Are you trying to hook a PC with no internet connection up through your laptop with the bridging built into Windows? I've done itin XP, but not needed to in Win 7 yet. It should still work though.

Many laptops have settings to automatically disable the WiFi chipset when a connection is made on the Ethernet port. It's done as a power optimization because normally you don't want to use WiFi if an Ethernet connection is available. You'll have to disable that before this works. Different vendors put settings in different places. Check the BIOS, Device Manager (properties of WiFi), or any vendor supplied power managers or optimizers.

Windows 7 will instantly disconnect the Internet and reconnect when a better connection presents itself. However, the wireless adapter should still be enabled and available.

If what you want is to use both connections in parallel in order to speed-up Internet transfer, then this is not possible. Windows 7 will always only ever use one connection.

If you wish to use your computer as a bridge for another computer to connect to the Internet, see this article : Turn Your Windows 7 PC Into a Wireless Hotspot. But just be prepared for a low bandwidth.

I actually want to connect to internet with my desktop throught my notebook wifi. So i don't want to create hostpot, but create a bridge between wifi and ethernet interface on my laptop. –  Janis Veinbergs Feb 7 '11 at 8:10
    
The hotspot is the bridge you are looking for. Otherwise, you need another router. –  harrymc Feb 7 '11 at 8:48
    
Oh, i think we have a misunderstanding in between. My desktop doesn't have a wifi, so he cannot connect to laptop. But instead i want: PC <--Ethernet-->Laptop<--WiFi-->Router NOT (as article says) PC <--WiFi-->Laptop<--Ethernet-->Router –  Janis Veinbergs Feb 9 '11 at 7:56
    
Have you checked that connection sharing is off on both wireless and wired before bridging? If you cannot bridge them, one solution to the problem is by getting a wireless dongle for the desktop. –  harrymc Feb 9 '11 at 10:22
    
any fix? I am having the same problem with the WiFi disconnecting as soon as the wired connection appears. –  Alexis K Apr 8 '11 at 15:57

You Need to disable switch off WIFI when Ethernet connection present, this should be in the bios Or if you have the HP utilities installed check for this setting in windows.
