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