The problem started last weekend when my Linksys RTP300 started acting squirrely for both Windows and Linux. Basically, as long as I statically assigned the IP address the Linksys was using, neither Windows nor Linux could resolve anything. As soon as I set it to get it's primary address via DHCP, then did a 'ipconfig /flushdns' under Windows, the Windows partition worked fine. However, the Linux partition (after several reboots) still gets squirrely address information. I can't get to Z, or several other sites. However, apt-get update;apt-get upgrade seems to work just fine.
Go figure.
