I have a bunch of medical-grade all-in-one workstations in use in a high-demand medical environment that spend their lives plugged in to power and wired networking. The systems came with a 30 minute backup battery and a wifi card for redundancy. The idea was that they'd run on wired net, and if a cable got tripped over or unplugged, the workstation would switch over to wifi, and case documentation could continue. The catch with this plan is that we need to know WHEN that switch-over to wifi happens so we can go remedy the problem with the wires that triggered the switch in the first place. The systems run WinXP (a vendor requirement). We don't run them totally on wifi because it's an electrically noisy environment and wifi not 100% reliable - that, and throughput isn't quite as good over wifi.
Can I get / how can I get these systems to alert me when they switch from wired to wifi networking?
