Hi, it looks as if the problem has been solved at the Mentone low income
hotel. Here is what one of the tech workers from Infinitech wrote about
their work there. Short story: I was correct, there was an issue
downstream from the Monkey Brains Power Over Ethernet Injector. The
problem did not lie with our machines, but upstream from our machines:
"Good news, we have the internet and wireless working at The Mentone. I
had to contact the ISP, Monkey Brains, and have them set the duplex speed
from Auto/1 Gigabit to Full 100Mbps, since on auto the various devices were
not properly communicating to each other. Currently, using a wired
connection (which is only when at the router itself in the basement), you
get 100 Mbps down, which is great."
Thanks to everyone who helped me with that issue!
