The Importance of 70-680 To Improve Your IT Career
To configure another computer with the wireless network, simply insert the USB flash drive into the computer. If the Wireless Network Setup Wizard ( setupSNK.exe ) does not launch automatically, you should manually launch it by browsing to the drive and double- clicking setupSNK.exe . This application is compatible with Windows XP with SP2 and Windows Vista.
Let’s say you’ve got a network with hundreds or thousands of Windows Vista and Windows XP (SP2) a certification computers that you want to configure with wireless network settings. Certainly you wouldn’t want to visit each computer individually and manually configure those settings. Luck- ily, as we’ve seen in the previous section, you can copy the wireless settings to a USB key.
But do you still have to visit each computer and manually insert the USB key to copy the set- tings? That would be awfully cumbersome. Fortunately, there is another option. You can copy the contents of the USB key to a shared location on the network. Then, you can configure a login script (which is easy to distribute using Group Policy) that will map the shared folder to a drive letter and run setupSNK.exe .
Note that setupSNK.exe must be run from a mapped drive or it will not launch. You can’t run it from a folder on your hard drive or directly from a shared folder without first mapping a drive to it.
Alternatively, you can copy the files to a CD or DVD and distribute them. When the CD or DVD is inserted, the Wireless Network Setup Wizard will launch automatically if Autoplay is enabled. This solution is helpful for computers that do not already have connectivity to a shared network location. However, for computers that can access a shared network location, using a shared folder with a login script is by far the easiest distribution method.
If you are having problems connecting to a wireless network, here are some things you can try: Ensure that your wireless network card is enabled. Many newer laptops and tablets have either a switch or a hot-key setting that enables and disables the wireless device. Ensure that the access point is turned on and that you are close enough to it. Ensure that there is nothing that might be causing interference of the wireless signal. Ensure that the SSID, encryption type, and passphrase/security key are correct.
Ensure that your wireless card and the access point are compatible. Cards that are com- patible with the 802.11b 70-680 standard can only connect to 802.11b access points, and cards using 802.11a can only connect to 802.11a access points. However, 802.11g cards can connect to either 802.11g or 802.11b access points.
If you are having trouble connecting to a network that does not broadcast its SSID, select the Connect Even if the Network Is Not Broadcasting check box in the Wireless Network Properties dialog box (shown in Figure 8.26).
Network protocols function at the Network and Transport layers of the OSI model. They are responsible for transporting data across an internetwork. Only TCP/IP is installed with Win- dows Vista by default.
