The on-site tech said the signal strength was -74dBm. He moved the location of
the subscriber module, and pointed it at a different tower. Signal strength is
now -41dBm. I asked him about guest access to the module, he said rapidwave
currently does not allow access, but that they might if enough people ask (so
be sure to ask). Here are the results showing the before and after:

PLUG to remote host:
- Before
250 packets transmitted, 249 received, 0% packet loss, time 249119ms
rtt min/avg/max/mdev = 4.966/19.857/216.240/23.845 ms
- After
250 packets transmitted, 250 received, 0% packet loss, time 249114ms
rtt min/avg/max/mdev = 5.658/10.686/43.507/3.989 ms

PLUG to remote host, stress test (ping -f):
- Before
1816 packets transmitted, 1776 received, 2% packet loss, time 24229ms
rtt min/avg/max/mdev = 39.451/49.585/145.304/10.129 ms, pipe 11, ipg/ewma
13.349/46.902 ms
- After
1816 packets transmitted, 1816 received, 0% packet loss, time 21123ms
rtt min/avg/max/mdev = 4.467/21.771/297.898/33.350 ms, pipe 23, ipg/ewma
11.638/18.953 ms

Qwest DS3 to remote host (local, qwest peered):
- Before
250 packets transmitted, 250 received, 0% packet loss, time 249076ms
rtt min/avg/max/mdev = 11.592/35.908/173.784/24.823 ms
- After
250 packets transmitted, 250 received, 0% packet loss, time 249022ms
rtt min/avg/max/mdev = 10.588/18.241/122.223/7.884 ms

As you can see, things have improved quite a bit. Bandwidth performance tests
showed about 2.3Mbps on a 100M file.
