Hello folks,
I have a small security question for you. I have a linksys wrt54gs wireless router. Runs good and all but i have a small concern with security which i dont know whether i should take action or just let be. It is on WEP encryption with the MAC filter enabled. (bad i know) but the reason is that my sister has a nintendo DS that she plays online with using the nintendo wifi connection. I was thinking about the connection and wondering if i should try to change it back to WPA again as she says she does have the nintendo usb adapter but i had trouble attempting to get it around firewalls and such in the past, but had an idea on setting up the device to run on a vm of windows xp with no security (would be a dmz zone for it) if i set it to WPA. I ask this because i dont know if i should be concered with packetsniffers still decrypting packets of data or if they physically need to be on the network to collect traffic. Thanks for any advice.

I would set the linksys router to use WPA and let your sister use the Nintendo USB Wifi gadget. According to this article:
http://en.wikipedia.org/wiki/Nintend..._USB_Connector

the Nintendo USB Wifi gadget can only work with Nintendo DS because it uses proprietory authentication.

By letting your main network use WPA, you will have better security.

Packet sniffers can collect data whereever they are because Wifi signals flow everywhere.

Ah ok, exactly what i thought, so if i can get vmware in that case to detect the usb device then it is good. only thing is i tried this before without success and most security software does not seem to like gamespy which i beleive it connects to, however i will try it and let you know how it goes.
