All right, I suspect my router might have gone bad, on account that if I jam the cord that comes out of the DSL modem into either computer, it works just fine, whereas if I put it back into the router, I get nothing. I’m going to fiddle with this a bit more; you may or may not see me here during the rest of the day.
Incidentally, while I was speaking to the nice Sprint representative about the problem, he was helping me reconfigure the PC box; which imvolved opening a DOS prompt, fidding with various settings and then sacrificing a chicken to the angry computer gods. When I put the DSL line into the Mac, all I had to do was enter a user name and a password. Score one for the Macs.
Anyway. Have fun with the rest of your day. Have you done an ice cream haiku yet?
