What is the consequence until this is resolved? Is the local WiFi usable?
Jake, did you say the access system is still functional?

We ran some tests and it seems like there is very high

ms) and packet loss (18% was the lowest I saw) on the wifi.
This is based on flood pinging a wifi-connected laptop from the gateway
(saros).
There appeared to be no such issues going from saros over ethernet to a
laptop or from saros over ethernet to the wifi access points.
This is very confusing because even though the APs have a central
controller, the traffic from the AP's clients does not flow through the
controller so something would have to be wrong with multiple APs at the
same time. Jake tested from both ends of the building to ensure it wasn't
just one AP.
Unless there is massive wifi interference at Omni or a malicious wifi
device, I can't think of what it could be.
Then of course there is the issue of the unreachable ethernet-connected
door computer. No idea there. More debugging needed to get to the bottom of
this.

I had to leave before i was able to figure out what was wrong and I can't
access the front door computer from theh network, so I don't know whether
card
access will work although now that i think about it, it probably does
work.
the wifi was being really really really slow tonight (thursday night) and
Arthur and I were trying to figure out what was wrong, and Yar and Marc
helped
remotely, but we never figured out where the problem was, and I didn't
realize
until i had to leave that the front door computer is entirely
inaccessible.
$ ping 100.64.64.11
"No route to host"
even though i power cycled it and it's getting a link light. I don't
actually
know where the other end of its ethernet cable is but since the front door
computer is important to security and accessibility, this worries me.
Can someone who understands the building's network please try to fix this
ASAP?
