# Windows – Multiple network connections on Windows 7

networkingwindows 7wired-networkingwireless-networking

I'm using Windows 7 and I have 2 networks:

• one wireless with internet connection
• one wired with no internet connection

The computer is connected to both. The problem is that although in Network and Sharing center it shows that the wireless connection has internet, it also shows that the computer is not connected to the internet.

If I only connect with the wireless, I have internet connection, but when connecting to the wired one it just can't access the internet anymore. And on the wired network I also have a printer that I want to share, but I can't see it if the wireless is also connected.

I suppose that there is a setting for default connection. What I want is to be able to connect to the internet over the wireless network and also to see the shared printer over the wired network.

And very important: I don't want the users on the wired network to be able to access the internet through my PC and the wireless connection (I don't want something like a bridge).

Revised, as I did not understand your question totally at first: The reason is probably because of the metric I describe below, but in your case, you want to give preference to the wireless network. You will set it's metric to 1, and the LAN to 2, and move the wireless to the top of the binding order.

You should post your IPCONFIG/ALL as you have not posted enough information to help you with that part of the question, but you want to make sure that your IP addresses, subnet masks, and gateways are all correct.

TCP/IP "SHOULD" automatically detemine that the wired connection is the fastest, but I have seen times where it does not do this correctly, especially if if gets plugged in after, and you already have a wireless connection, which is connected and active.

If you want to guarantee that the wired network gets preference, do the following:

Go into your Connection>Properties for both TCP/IPv4 and TCP/IPv6 (if in use)set the metric for your LAN connection to 2, and your Wireless to 1 (for most people, they would want these reversed). In the screenshot you can see where I set this for my wireless adapter. If you hit F1 right there, you can see this quote from the help file:

Automatic metric specifies whether TCP/IP automatically calculates a value for an interface metric that is based on the speed of the interface. The highest-speed interface has the lowest interface metric value.

Interface metric provides a location for you to type a value for the interface metric for this network connection. A lower value for the interface metric indicates a higher priority for use of this interface.

Then you can also change your binding order by opening Control Panel>Network and Internet>Network Connections>Advanced>Advanced Settings as in this screenshot:
