Access Control - 3Com OfficeConnect 3CRWE454A72 User Manual

If passphrase encryption is to used then tick the passphrase box. If
Manual HEX is to be used leave this box unticked.
If you encounter any difficulty when you enable WEP ensure that you
check that each key on your wireless computer is exactly the same as
each key on your Access Point. In other words, Key number 1 on the
Wireless computer must have the same Hex number as Key number 1 on
the Access Point, Key 2 on the Wireless computer must match Key 2 on
the Access Point and so on.
The Active Transmit Key selects which of the 4 Keys the Access Point uses
when it transmits. You can change the selected key periodically to
increase the security of your network.
Some wireless adapters have only one key available on their WEP
configuration page. If this is the case ensure it is the same as Key 1 on the
Access Point and that it is selected as the active transmit key.

Manual Key Entry - This method allows you to manually enter hex
keys. Virtually all manufacturers support this scheme. Hexadecimal
numbers are formed from 0-9 and A-F. Enter 10 or 26 digits
depending on whether you are using 64 0r 128 bit WEP respectively.
Passphrase - This is another common method. In 64 bit WEP, the
passphrase will generate 4 different keys. However, in 128 bit WEP,
this method only generates 1 key which is replicated for all 4 keys. The
passphrase can be up to 31 characters long and may contain any
alphanumeric characters.
