Resolving a lost internet connection
Once I received a call from a woman quite agitated that her computer had inexplicably lost its connection to the internet two days earlier. When I arrived she showed me her wireless access point with its little antennas sitting in the front room of the house. I went to work testing it using my own laptop and quickly ascertained that her internet connection was working very well; there was a good strong wireless signal with the identifier (SSID) named “Motorola” or something like that.
