creating 2 different wireless configurations

view full story

http://forums.opensuse.org – I am fairly new to linux and this is more of a curiosity question than a problem. I haul my laptop between two different places and was wondering how I can set up two different configs, being able to load either quickly. I'm running openSUSE 11.2 and use KDE4, but I don't use Knetworkmanager to manage my network, I use ifup (although I don't know too much about that either). (Distributions)
