Overwriting an Existing Static WEP Key
Follow the steps below to overwrite an existing static WEP key.
Note You can overwrite existing WEP keys, but you cannot edit or delete them.
Step 1 Look at the current WEP key settings in the middle of the Network Security screen. A checkmark
appears in the Already Set? box for all existing static WEP keys.
Note For security reasons, the codes for existing static WEP keys do not appear on the screen.
Step 2 Decide which existing static WEP key you want to overwrite.
Step 3 Click within the blank field of that key.
Step 4 Enter a new key, following the guidelines outlined in Step 6 of the “Entering a New Static WEP Key”
section on page 5-26.
Step 5 Make sure the Transmit Key button to the left of your key is selected, if you want this key to be used to
transmit packets.
Step 6 Click OK to return to the Profile Manager screen; then click OK or Apply to save your changes
Disabling Static WEP
If you ever need to disable static WEP for a particular profile, select No WEP under WEP on the
Network Security screen, click OK, and click OK or Apply on the Profile Manager screen.
Note Selecting LEAP from the Network Security Type drop-down box on the Network Security screen
disables static WEP automatically.
Enabling LEAP
Note LEAP authentication is supported only on client adapters that support WEP and use PCM/LMC/PCI card
firmware version 4.13 or greater, mini PCI card firmware version 5.0 or greater, or PC-Cardbus firmware
version 4.99 or greater.
Note In order to use LEAP authentication, your client adapter and access point firmware must have matching
802.1X draft standards. That is, if the access point uses draft 8 firmware (prior to 11.06) or has draft 8
selected, the client adapter must use draft 8 firmware (prior to 4.25.x). Similarly, if the access point uses
draft 10 firmware (11.06 or later) and has draft 10 selected, the client adapter must use draft 10 firmware
(4.25.x or later). Mini PCI firmware and PC-Cardbus card firmware were first released at draft 10.
