Every time you connect to a wireless network (your home, the local wi-fi cafe, your neighbor), Windows adds that location to a list of wireless networks. The list is configured according to the order by which the connection was made. Your home may be third on the list while the coffee shop may be first on the list.
Each subsequent time you attempt to connect to a wireless network Windows will first try the connection at the top of the list and then proceed to go down the list until it connects to the intended network. Are you sure that your priority wireless connection is first on the list? If not, Windows will be slow to connect as it goes down through your wireless networks list until it finally arrives to the connection that you actually want.
To change the order of wireless connections, do this:
1. Click Start>Control Panel
2. Click>Network and Sharing Center
3. Click>Manage Wireless Networks (located in the left pane)
4. Right Click>The wi-fi network that you want Windows to try first, and select Move Up
5. Move your priority network up to the top of the Wireless Networks list
6. Click OK to close out
Professor Randy says: Speed up your wireless network connection by prioritizing the order of wireless connections shown in the wireless network list. Your computer will then “grab” the connection of choice without having to go through any non priority networks.
