NETGEAR Next 300 Mbps Wireless USB 2.0 Adapter WN121T User Manual2-3v1.0, August 2006ProfilesThe WN121T Smart Wizard uses profiles to store all the settings for a particular wireless network. There are two special profile names: Default and Profile. Default: The Profile named Default automatically scans for any available network. You cannot change this profile name. Profile: If you do not enter a name in the Profile Name box, then the name Profile is used to save your settings. If you do this more than once then you will be asked if you want to replace the previous settings stored in Profile.Adding ProfilesYou can store multiple profiles and recall the one which matches the network you want to join.If you use your computer to connect to different wireless networks, you can create a profile for each wireless network. Then, you can easily load the profile that has all the settings that you need to join the network you are using at the time. There are two types of wireless network profiles that you can set up:•Access Point (Infrastructure) — connect to an access point or router with the 802.11 infrastructure mode. For example, this mode is used when computers in a house connect to an access point that is attached to a router, which lets multiple computers share a single cable or DSL broadband Internet connection.•Computer-to-Computer (Ad Hoc) — connect directly to another computer with the 802.11 ad hoc mode. For example, Ad Hoc mode is used when two Windows computers are configured with file and print sharing enabled and you want to exchange files directly between them.For more information on 802.11 wireless network modes, see the wireless reference document at:http://documentation.netgear.com/reference/enu/wireless/index.htm.Setting up a Profile to Connect to an Access Point or RouterFollow these instructions to set up the Next 300 Mbps WN121T Wireless USB 2.0 Adapter to connect to a wireless access point or router.

Ad Hoc mode is an 802.11 networking framework in which devices or computers communicate directly with each other, without the use of an access point. For example, this mode is used when two Windows computers are configured with file and print sharing enabled and you want to exchange files directly between them. Follow the instructions below to create an Ad Hoc mode profile.Note: If you cannot connect, see Chapter Chapter 3, “Troubleshooting. Also, for problems with accessing network resources, the Windows Client and File and Print Sharing software might not be installed and configured properly on your computers. Please refer to “Internet Networking and TCP/IP Addressing:” in Appendix B.Note: Ad Hoc mode will not work using DHCP settings. Ad Hoc mode requires either static IP addresses (such as 192.168.0.1) or the IPX protocol. For instructions on setting up static IP addresses on a Windows PC, refer to the PC Networking Tutorial included on the NETGEAR CD.
