Testing 5 wireless cards for wifi hacking

WiFi PCMCIA pro hacking Hi everyone. The financing system and the cooperatin surprisingly started to work for you. Thanks to this there was bought or handed few wifi cards so now you can read a comparison of wireless cards in this text. Hopefully it will save you some money in future investments.  Buying another hardware is coming soon. So before starting to write I ask you, devoted portal, forum or IRC channel users to stay tuned. More stuff is coming. Tested wireless card, metodic, 5dB omni & 17dB yagi wireless antenna..

WiFi cards in the test

We have tested 5 wifi cards. USB wifi card Edimax 7318USg, PCMCIA wifi card Wistron CB-9 Ext, minipCI express wifi card Intel Pro Wireless 3945, PCMCIA wifi card Ubiquity SRC Super Range 300mW and USB wifi card Alfa Networks 500mW.

How the test was run?

1.) The connection quality was recorded at every wifi card on a directional atenna against Access Point in a 3 metres distance.

2.) Every wifi card with Yagi 17 dB antenna aimed at 3 kilometres far away access point was tested.

3.) The signal quality of a choosen Access Point 150 metres far away was recorded at every wifi card.

4.) The number of wireless networks detected on frequency 2.4 GHz in 2:30 minutes at programme Kismet was recorded.

5.) The number of wireless networks detected on frequency 2.4 GHz in 2:30 minutes at programme Netstumbler was recorded.

You can do your own comparison as you wish. The results are obvious and if you expect the best result to be at the strongest card you will be disappointed.

The chart will be completed by data from wireless signal strenght meter + values from WiFiSlax Linux.

Output power will be completed into the charts after the wireless signal strenght meter will arive (I assume in 20 days). It is obvious from the test that the integrated wifi card (in our case Intel Pro Wireless 3945) has in a random laptop inside a building a low chance to detect networks outside the space. Don´t bother with packet injection or similar stuff. WiFi card Alfa Network 500mW in Windows operating system works strange.

I don´t know what exactly it is but Network Stumbler at 87 displayed wifi networks although having a different MAC address displayed some wireless networks 3x (the same SSID different MAC address). The loser in sensitivity and ability to detect networks (or injekce, or crack WEP or detecting handshake) is Edimax 7318 USg. \The most expensive Ubiquity Super Range 300mW has a higher power but can be compared to Wistron CB-9 Ext. The advantage of Ubiquity is that in programme Kismet the channel hopping works smoothly. This can not be said about CB-9 Ext.
