Choose: IP Address, Subnet Mask and Default Gateway
IP Address = 10.0.0.97
Subnet Mask = 255.255.255.240
Default Gateway = 10.0.0.110

You configure a second profile for your home network. For several weeks, the wireless connection works fine. Whether you are at home or at work, you can start your computer and make a connection without browsing for the list of available networks. One day you come in to work to find that you can't connect. You check with the network administrator, and he states that they have prevented the SSID of the company network from being visible. You need to make it as easy as you can to connect to the company wireless network now and in the future. What should you do?
In the wireless network profile, select Connect even if the network is not broadcasting.
You have a laptop computer that runs Windows 7. Your computer is configured to connect to the wireless network at work using a wireless profile named Company1. The profile is configured to connect using 802.11b. During a recent upgrade, your company has added an 802.11n wireless router. The router is configured to support 802.11n using one radio, and 802.11b/g with the other radio. You create a second profile on your computer for the 802.11n network. You notice that your computer is connecting automatically using 802.11b. You want the computer to connect first using 802.11n, and only use 802.11b if 802.11n is unavailable. What should you do?
Move the 802.11n profile up in the list of the preferred networks.
You are configuring a small wireless network with 10 client laptops that require network access. You have configured a new wireless access point with an SSID that is not broadcasting. You have manually created a network profile on one computer, which successfully connects to the network. You would like to configure the network profile on the remaining clients with the least amount of effort. What should you do?
Use the Copy this network profile to a USB flash drive option to save the wireless network settings to a USB flash drive. On each additional client, insert the USB drive and run the utility to copy the profile settings to the client.
