You may make changes, as detailed here: 1.Select one of the two options: Create with Passphrase or Manual Entry . A Passphrase makes you easier to enable WEP because it automatically generates the WEP hexadecimal numbers for the key. If the wireless network Access Point uses a Passphrase, you can also use that here. Otherwise, you will have to manually enter the hexadecimal numbers.2.Create with Passphrase option: pull down the Key Length options and select the 64-bit or 128-bit, then type in your Passphrase.3.Manual Entry option:•Pull down the Key Length options and select the 64-bit or 128-bit , encryption method.•In the Encryption Keys fields, specify the WEP keys: For 64-bit encryption :Hexadecimal:10 hexadecimal digits in the range of “A-F ”, “a-f ” and “0-9”(e.g. 11AA22BB33)Profile SectionThe Profile area allows you to set values for all parameters by selecting a previously defined profile.T o create a profile, in the Profile Name field, type a Profile Name ; for example: Home, Office.When you are done, click the Save button in the Profile area, and click Apply .

In an Ad-Hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network — each node can generally communicate with any other node. There is no Access Point involved in this configuration. It enables you to quickly set up a small wireless workgroup and allows workgroup members to exchange data or share printers as supported by Microsoft Networking in the various Windows operating systems.Some vendors also refer to ad-hoc networking as peer-to-peer workgroup networking.3to continue or select another tab.This table describes the options available from the Statistics section:DescriptionCable/DSL Modem Desktop (or Notebook) PCwith MA111 802.11bMR814 Cable/DSL 802.11bInternetDesktop (or Notebook) PCMA111 802.11bWireless USB Adapter802.11b Wirelesso set up an Infrastructure network operating with standard protocols, do the following:Technical SupportPLEASE REFER TO THE SUPPORT INFORMATION CARD THAT SHIPPED WITH YOUR PRODUCT.By registering your product at /register , we can provide you with faster expert technical support and timely notices of product and software upgrades.NETGEAR, INC.Support InformationPhone: 1-888-NETGEAR (For US & Canada only) See Support Information card for other countries.E-mail:*******************©2003 NETGEAR, Inc.
