New router...

There was at least one good reason not to change the network password when I installed the new router, and that had to do with not having to go around to all of the devices that had been connected to the old router and reconfigure them with a new password. (About the only analogy I can draw here is the activity in a clock shop whenever daylight savings time kicks in or out.)

On the other hand, the network had been puttering along on the old password for more than two years, so changing it seemed like The Right Thing To Do™.

Cheers...
