Are you sure, that this is secure..? Note: I am NOT a computer security specialist, but that's how I see it: When you are (hard-wired) on a wireless-network, you are "open" (at risk) for any and all attacks by a smart hacker ... I guess some on this very forum here are able to "look" into your whole network.
Actually, I have such a configuration you are suggesting: PC hardwired (to a D-Link DI-524 802.11g router), laptop wireless (with DWL-G630 802.11g cardbus adapter).
I checked my network with several programs and it looks like it's pretty secure (when attacked via the Internet). However, I don't feel too save against an attack from a "nearby hacker" ... access the laptop (shared files etc.) via the 802.11g wireless cardbus adapter. Yes, I have a (software) firewall at the laptop... but is this enough? All I want is a 99% secure infrastructure ... I know, a 100% security does not exist.
I have read a recent posting regarding PC security at this forum, very interesting. BTW, I started installing "HAMACHI" but got stuck (could not join "hamachi network or so..) and stopped the installation ....
