Yes, much better. I also noticed a problem on the HamWAN side,
where that sector was configured for only 5MHz service instead of
our normal 10MHz. I've changed the sector config, and you should be
getting twice the bandwidth now.<br>
<br>
I tried to run a speed test, but noticed your bandwidth-server was
still set to require authentication, so I've logged into your modem
and turned that off:<br>
<br>
[eo@K7ITE-Lookout] > /tool bandwidth-server set authenticate=no<br>
<br>
I also noticed you still have an "admin" account. If it's not
properly password protected, this may be dangerous now that your
modem is on the Internet. I have left it untouched.<br>
<br>
I also noticed you have the "winbox" service running. This is also
dangerous, as it's full of exploits. I have left it untouched, but
you should probably disable it. (/ip service disable winbox) We
should update the website instructions to disable this by default.<br>
<br>
I also noticed your ssh is on port 22. This will get more hacking
attempts than port 222. You can change it with /ip service set ssh
port=222.<br>
<br>
With the bandwidth-server available on your end, I ran a speed test
from the sector to your modem:<br>

This is the performance you can expect from a 10MHz MIMO link that
has good signal.<br>
<br>
The current-distance is reported in km, not miles. It's not
round-trip distance, just physical distance between the modems.
There is a separate metric for round-trip-time, which is measured in
microseconds: tdma-timing-offset=202. You can do the speed-of-light
math to get a more precise distance than the 1km granularity
reported by the "current-distance" field.<br>
