Think laptop. Connect to one network with one profile. Move to new site, connect to network with another profile. etc...
Thanks, Peter. I just picked up a laptop to take with me while working on client sites. (Always can find a drop, but never a computer.) And each client has different network configurations. This way I can create a hw profile for each client, and access their system without a problem.
CRC, is this what you are trying to do? Or single computer with access to multiple lans via a single connection?
