802.11 a/b/g/n Card Installation Notes and Issues
Keep the following notes and tips in mind when working with 802.11
a/b/g/n wireless cards:
After removing and replacing PCMCIA adapters, it’s a good idea to
restart the system before launching Sniffer Portable Professional.
This is especially important if you replace an Ethernet card with an
802.11 adapter, or vice-versa.
After exiting Sniffer Portable Professional, it may take up to a
minute for the wireless card to transition to normal wireless
network participation.
Wireless Client Utilities provided by your card’s vendor will not
function with the Sniffer enhanced driver installed. Use the
Wireless Network Connection utility included with Microsoft
Windows instead.
While configuring the 802.11 a/b/g/n card, you may see the
following warning: Can not access your wireless card. Please
remove and reinsert PC card to activate settings.
This warning can safely be ignored.
Use the Safely Remove Hardware option when removing the
cardbus card. Make sure Sniffer Portable Professional is properly
shut down before the card is removed.
For improved performance, you can unbind the Aegis Protocol
(IEEE802.1x) from the card driver, as shown in Figure 2-1.
However, keep in mind that unchecking this option can interfere
with any VPN clients you may be using. If you do decide to disable
the Aegis Protocol during Sniffer Portable Professional analysis,
reenable it before connecting to your VPN.
