Netswitcher is an excellent option. Another possibility is to set up hardware profiles on your system.

Create 2 hardware profiles. Then you can switch between the 2 as needed. Just disablethe network card that's not needed for the different logins. Also create a different profile for the 2 networks. It's not that hard to set up and you can use help if needed.

Im assuming you have either an integral or a PC card NIC available to use. Just assign a different IP range to the wireless and wired NICs.
