When you want to switch back to using wireless normally you will need to re-enable the connection by doing essentially what you just did backwards:

2. Double click on Network Connections
3. Right click on the Wireless Network Connection and
4. Choose Enable
Or if you do not want to disable you wifi you can set it to only connect to preferred networks read this:
1. Wireless Auto Configuration attempts to connect to the preferred networks that appear in the list of available networks in the preferred networks preference order, if the preferred networks are configured to automatically connect (the Connect when this network is within range checkbox is selected on the Connection tab for the properties of the preferred wireless network).
2. If there are no successful connections, Wireless Auto Configuration attempts to connect to the preferred networks that do not appear in the list of available networks, in the preferred networks preference order. This is done so that a Windows wireless client can connect to a hidden wireless network, one that is either not broadcasting its SSID or broadcasting an SSID of NULL. Configuring hidden wireless networks is used as a security measure to prevent malicious users from detecting and attempting a connection to a wireless network. However, the SSID is included in other types of wireless connection management frames and is easily discoverable by either capturing wireless management frames or using tools available on the Internet.
3. If there are no successful connections and there is an ad hoc network in the list of preferred networks that is available, Wireless Auto Configuration tries to connect to it.
4. If there are no successful connections and there is an ad hoc network in the list of preferred networks that is not available, Wireless Auto Configuration configures the wireless network adapter to act as the first node in the ad hoc network.
