Configuring wnda3100 with wireshark on windows : adapter not found

hi,

My aim is to test and verify my wlan is well secured and safe.
so i'd like to use wireshark with my wnda3100 adapter (usb netgear).

but once, wireshark is installed, it doesn't show my usb wireless adapter.

Do you know why ?

My Os windows xp is original sp3 updated, and my drivers are Ok : 3.0.0.141

thanks for your little help.

Mike

best regards
