This problem started about two weeks ago and there have been no references in the syslog files to "wlsdev18-2" since June 29. I assume I did something at that I did something on that date to cause this, but I have no idea what (could have been some mucking with Samba while attached to the AD network at work).

Yes. Nothing sticks

both get pinged

It hasn't mattered. It's mostly been wireless, but the problem first surfaced while wired.

I'm probably going to troubleshoot for the rest of the week and then re-install next weekend if there's no solution.
