Wireless Network with Server not running DHCP need to take home where DHCP on router

I have a laptop that I am using at both home and work using the wireless connection. At home I use a wireless router that is directly connected to the modem so I have the TCP/IP settings as Obtain automatically. However, at work we are using Windows 2000 Server not running DHCP. I have a wireless router at work but when I enable DHCP I lose the connection to the network. The only way I can do this is to statically assign the TCP/IP settings. Is there anyway to either set up multiple wireless connections where each has different settings on my laptop (ex. One has automatically optain other has static?) Or is there a way to set up the wireless router at work to work correctly? Thanks for the help
