Wireless access points

On a wireless network a wireless access point is a place where a user can jump onto the wireless network. Wireless access points (base stations) are connected to an Ethernet hub or server and transmit a radio frequency over an area of several hundred to a thousand feet which can penetrate walls and other non-metal barriers. Roaming users can be handed off from one access point to another like a cellular phone system. Laptops use wireless modems that plug into an existing Ethernet port or that are self contained on PC cards, while stand-alone desktops and servers use plug-in cards.

Manuals and help files

For "private" access points, i.e. those not part of the DNO-maintained Yale Wireless System, ITS REQUIRES that encryption and authentication provided by WPA be employed all the time (although the older standard, WEP is acceptable if WPA is not supported).  We may disconnect access points not meeting this requirement after appropriate notice.

For "public" access points at YSM, connection is only possible by using VPN, thus ensuring encryption and authentication.

Definitions

SSID
The SSID is the unique name shared among all points in a wireless network. The SSID must be identical for all points in the wireless network. It is case sensitive and must not exceed 32 characters.

Channel
Select the appropriate channel from the list provided to correspond with your network settings, between 1 and 11. All points in your wireless network must use the same channel in order to function correctly.

WEP Encryption
Select the WEP setting from the pull-down menu, 64-bit or 128-bit Recommended. This access Point’s WEP encryption is unique to Linksys and may conflict with other vendors’ WEP encryption.

Pass phrase
Instead of manually entering WEP keys, you can enter a Pass phrase. This Pass phrase is used to generate one or more WEP keys. It is case-sensitive and should not be longer than 16 alphanumeric characters. (The Pass phrase function is compatible with Linksys wireless products only. If you want to communicate with non-Linksys wireless products, you will need to enter your WEP keys manually on the non-Linksys wireless products.) The second Security Settings screen, shown in Figure 5, shows the WEP key. If you entered a pass phrase, then the Key 1 field will display the automatically generated WEP key. If you did not enter a pass phrase, then enter a WEP key in the Key 1 field. Each point in your wireless network must use the same WEP key for the network to function properly.

Key 1
WEP keys enable you to create an encryption scheme for wireless networks. If the WEP key hasn’t been automatically generated, then manually enter a set of values. (Do not leave the field blank, and do not enter all zeroes. These are not valid key values.) If you are using 64-bit WEP encryption, then each key must consist of exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, then each key must consist of exactly 26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.
