There is a public network, GUEST, and an internal network for
access to the telescope networks, APO. APO is best for those
who need access to the internal networks that have the web server
to create web pages and manage housing and the telescope
networks. The GUEST network and APO network are identical as
far as performance is concerned. They are separated in the
firewall with routing rules. If someone needs access to the
APO internal networks, they need to send an email to IT.
The SSID is GUEST or GUEST# where # is an integer number, i.e. GUEST1, GUEST2, ... This network is 172.16.0.0/24, with users IPs 172.16.0.11-172.16.0.254. The wifi is open access protected by a firewall. There are network jacks on the walls which are provided for the network phones and other APO network devices.
There appears to be a WiFi problem with the Yosemite and El
Capitan OS installed on the newer laptops. Older laptops
with an older OS works without problems. The newer users are
talking about poor performance and dropouts. There is a
problem with the newer OS caused by Apple using a second
connection to the WiFi for Bonjour. I have asked several
people to try turning this channel off with a “ifconfig awdl0
down” command from the command line. It is reported that
fixes the problem.
If there are problems with the WiFi, tell IT the details of what you are seeing. It is impossible to fix things when the complaint is, it is not working very well. It would help to know the OS being used, the rough age for the laptop, the things you were trying to do (Skype, big transfer, etc.), and what is the problem. These have been the clues that have helped to direct finding the fix. It would also be good to hear when something works, such as turning off the awdl0 device.
