Y'know how they say during a storm to unplug everything, including the internet cable? Well, I did, sort of, and forgot that I did. Actually I unplugged the modem from the router. (The modem attaches to the outside world via a coax cable, and I hate fiddling with those little screw-on ends!) I figured losing the modem to a lightning strike wouldn't be as bad as losing both the modem and the router.
So anyway, I figured that out thanks to shockwave77598's comment on my pre-previous entry. And finally... I'm back, baby!
