Is it possible for a Windows XP PC's LAN connection to be used by a few other PC's via wifi to a USB wifi card like the D-Link DWA-160? Here's the connectivity map:
multiple PC's wifi USB wifi card acting as an access point Windows XP PC running some kind of .exe or java packet forwarding software hardwired LAN Internet
One constraint is that I want to do this without "installing" software, but I can run an .exe or java software that I carry with me on a USB memory stick. There's no need to leave anything permanent, as I'd only need this wifi access for other people in the room temporarily during meetings.
The reason I can't just directly connect a wifi access point directly to the LAN is that a user must log into the PC to access the LAN and Internet. Direct connections to the Internet are prohibited. But after logging onto the PC that PC can access the Internet via the LAN, so in theory any laptops that use that PC as a gateway could have Internet access though it, too.
I seem to recall doing something like that a decade ago, just using a very short and simple java program to receive IP packets and forward them on, & vice versa, but we were using a pair of LAN cards in a PC. I was hoping that there might now might be a turnkey wifi USB solution on the market to do all this. Is there?
