Unfortunately the ISP's AP doesn't respond to ping, however the next hop
in a traceroute, which is likely their router, shows the packet loss.

No digis out here in Vernal. In fact, the only 802.11* signal I pick up
outside with my laptop is my dad's linksys, so perhaps it's not 2.4 (or
perhaps the gain is relatively low and requires a better antenna). I
don't know about illegal signal strength, but I do know that just about
anywhere in Utah valley I can pick up a couple of digis signals with my
laptop.

I'll give smokeping and the papers Halcrow recommended a try.

Welcome back, Josh.

There's nothing remarkable about it. All one has to do is hit the 
right keys at the right time and the instrument plays itself.
