I don't see any mention in the article that having the device connected to IP is causing the issue. Sounds like a touchscreen / code issue. The FDA's article also doesn't specify anything other than that. Hospira has completed an investigation into customer reports and has found the major contributor to be software related. Other contributing root causes that have been identified include damaged connections, physical damage and other touch screen defects.
It would be nice if the article would stick to the point and not confuse issues.
