[clue-tech] intermittent connection problems

[Jason S. Friedman]

I have heard from this list: 1) DNS, 2) IPv6.  Regarding IPv6, I read at 
  http://ubuntuforums.org/archive/index.php/t-87798.html instructions 
for disabling IPv6,  The instructions refer to /etc/modprobe.d/aliases, 
but I have no such file on my machine.

Regarding DNS, I changed to OpenDNS, but that does not help:

wget www.frii.com

[and no response]

What IP address do others show for www.frii.com and www.microsoft.com?

you're experiencing, and the solution was to disable IPV6.
