Wifi: Tales of a Lonely Repairman

"Any sufficiently advanced technology is indistinguishable from magic."
- Arthur C. Clarke, 1961 (Clarke's Third Law)
Twenty years ago the computer / network technician, whether bearded or clean-shaven, academic or corporate, occupied a position of prestige. He was a deity to be revered, sacrifices made in order to ensure the proper order of the mystical bits in his purview.

To the right, a couple of examples of this type of wifi-vision and a visit from the friendly neighborhood repairman.
