An easier solution would be to allow the laptops to be connected to both wifi and LAN network at the same time.
To do this, you will need to change the network card priority so that the wireless connection remains active when a wired connection is made.
The first step is to get to the "Control Panel > Network and Internet > Network and Sharing Center" page. On the left side of that page, click the link "Change adapter settings". This should bring you to the "Control Panel > Network and Internet > Network Connections >" page.
Select the wireless connection, right-click "Properties", and provide an admin password (if necessary). This should bring you to a dialog box named [wireless connect name] Properties".
In the list box titled "This connection uses the following items:", scroll down to "Internet Protocol Version 4 (TCP/IPv4)" and select it. The "Properties" command button will enable; click it. This should bring you to a dialog box named "Internet Protocol Version 4 (TCP/IPv4) Properties".
Click the "Advanced" command button. This should bring you to a dialog box named "Advanced TCP/IP Settings".
Near the bottom of the dialog box, there should be a check box named "Automatic metric". Uncheck it. That will enable a text box named "Interface metric". Fill in a number. It needs to be larger than 1 (reserved for loopback) and the number you choose for the wired network (see below).
Click three "OK" command buttons to return to the "Control Panel > Network and Internet > Network Connections >" page.
Repeat the above for the wired connection:
Select the wired connection, and right-click "Properties" to get to the [wired connection name] Properties" dialog box.
Select the IPv4 list entry and click "Properties", and on the next dialog box click "Advanced".
Again Uncheck "Automatic metric", and fill in a number in the "Interface metric" box. It needs to be larger than 1 but smaller than the number you chose above.
