Hi David,

Nice to see you have had some success with HamWAN! -68 dBm is a great
signal strength and I'm sure many others here envy your clear line-of-sight
to a HamWAN site.

I took a look at this and the slow hop between you and the Internet is
between our Capitol Park and Queen Anne sites. That link is sub-optimal
because it's connected off the sidelobe of a dish that is pointed at the
SnoDEM site. It's enough to work, but as you've found it's not the fastest.
There's nothing you can do about it.

The way I investigated this is by doing speed tests to each of the hops in
your path. You can find the path like this (from your modem):

/tool traceroute use-dns=yes

( is Google public DNS servers. It's likely to always be up. Feel
free to use any other target depending on the nature of your test.)

To run a speed test (this should work to all HamWAN routers--let me know if
it doesn't):

/tool bandwidth-test protocol=tcp CapitolPark-S2.hamwan.net

This will test speed between your modem and CapitolPark-S2.hamwan.net. You
can test the other direction by adding direction=transmit to the command.

This is a perfect forum to ask questions like this.
