RE: Wireless discovery and WEP cracking on one 802.11b card

[David Gabler <dgabler () TRUELINK com>]

A bit late but better than never,

The dlink 650 (which is manufactured by the gemtek) can _*easily*_ be
modified to accept an external antenna.

To make a clean connector you need to purchase an end launch MMCX jack:

(you will also need a dremmel like tool, or a file (a drill will work but it
will not be clean) to cut out the hole for the end launch plug)

And then the appropriate MMCX plug.
e.g.
http://www.digikey.com/scripts/us/dksus.dll?Criteria?Ref=10850&Cat=21758713

If you do not care about a clean look check out:

For good instructions on removing the antenna cover check out:
http://users.skynet.be/chricat/DWL-650.html

To roll your own antenna check out:

The antenna describe on the above referenced page is fairly easy to build
(build mine in a few days only working nights).

However good luck!

Subject: Wireless discovery and WEP cracking on one 802.11b card


I would like to perform discovery of 802.11b networks and WEP cracking
on the same card.  Currently WEP cracking is limited to a select number
of Prism II cards.

Addtron AWP-100 
Bromax Freeport 
Compaq WL100 
D-Link DWL-650 
GemTek (Taiwan) WL-211 
Linksys WPC11 
Samsung SWL2000-N 
SMC 2632W 
Z-Com XI300 
Zoom Telephonics ZoomAir 4100 
LeArtery Solutions SyncbyAir LN101 

Unfortunately from my research these cards are lacking when it comes to
their range when compared with other cards such as the Cisco Aironet
340/350 or the Lucent Orinoco cards.  It also appears that these cards
do not have connectors for external antennas.  If this is true, is it
asking too much for the above cards to do net stumbling?  If so, is
there a way to boost the gain to one of these cards so it would be more
effective in this role?  Alternatively, are there other cards better
suited for the discovery of 802.11b networks that can also perform WEP
cracking?
