One issue regarding senior people and wifi is that wireless rounters need to be reset from time to time. You try to go online and you have no internet. Is it the service? Is it the modem? Is it the router? If your parents are like my neighbors, they will get frustrated. My neighbor insists on having wireless because they don't want wires. Okay, except they use their only computer, a laptop, as a desktop and it is on the desk that has the internet connection right underneath it. Every two weeks my wife has to go and reset all of their stuff to get them online. If they would just plug the darn thing into the modem and skip the router, they'd have a lot less problems.
