You can ask. And inform about how a hotspot is crushing an AP and several 
people's connectivity.

Hmm... By this do you mean "are not permitted to be connected to the
campus network"? Cause if somebody's got a wifi router connected to a
cell phone data network you can't legally tell them they can't use it...
Whether it's on the same channel as your wifi or not.

Packetfence 9.3.0 and eduroam

[Nadim El-Khoury]

Dear All,

We recently joined eduroam and we have Packetfence 9.3.0 as our Radius
server. Has anyone set up Packetfence and connect it with eduroam?

We followed all of the instructions and still, we are not able to properly
authenticate.

Any input or help would be appreciated.

Best,

Nadim El-Khoury

Re: [WIRELESS-LAN] neighbors 'jamming' 2.4GHz spectrum

[Seth Bean]

The neighbor does not appear to be playing nice in the public wireless 
spectrum, knowingly or unknowingly.  Perhaps you can check to see if you are 
using all the channels there are - perhaps work with your Public 
Relations/Marketing team to reach out to them and address it with the neighbor 
through a meeting.  Often times this is just someone being funny and have no 
clue what "40Mhz" or "2.4" means.
As a policy, we do not allow personal APs, wireless routers, or anything else 
that interferes with the campus network - I actively shut down ports to 
personal access points and routers.  I will often follow this up with a 
scheduled, supervised visit to the room to discuss what caused them to want to 
use it - occasionally there is an issue I'm not aware of, or was not reported.  
It often turns into a learning and beneficial meeting so they know we care and 
want them to have good wireless.  The students are often not trying to be 
malicious - they just want to get wireless reliably on their 
phone/tablet/laptop/game console/streaming device.  When it doesn't work and 
doesn't get better, they often don't know who to go to, or that they CAN ask 
questions.  I would suggest leading by example - see if you can turn down the 
power on the APs on the edge of your campus map to provide coverage for the 
area you need, but not beyond, so you are not flooding the wireless spectrum 
with your enterprise-grade radios.
Just a suggestion.  Its fun having a campus in a densely populated area.

I put quotes around jamming, because it isn't technically.
We are seeing an SSID named 'ACCESS DENIED' on 2.4GHz channel 4, with a 40MHz 
width and channel 8 extension.
The signal is not high enough to interfere with most clients, but for some of 
our meshed access points, the signal level is fairly close to the signal 
available from the mesh's host access point.

Is this a common thing?  Have others seen the same on their campus, and if so, 
what are the policies and practices that you follow?

I know the signal is coming from off-campus, but I don't have assurance that it 
is malicious intent or that it is intended to disrupt our campus network.

RE: [WIRELESS-LAN] neighbors 'jamming' 2.4GHz spectrum

[David Pifer]

We have a standard as follows “Personal wireless access points, network 
switches, and routers are not permitted on campus as they can interfere with 
the functioning of the campus network.”

https://indstate.teamdynamix.com/TDClient/1851/Portal/KB/ArticleDet?ID=94518

Now granted it doesn’t say want we are allowed or not allowed to do. So we can 
start with a healthy discussion and then if necessary we just shut off the 
ports in their room. When they call and complain it is discussed again. Since 
it is a violation of policy it could in theory escalate to a higher authority.

We actually chased one through about 3 dorm rooms, disabling ports as we went. 
When those other rooms started to complain we told them what caused it to be 
disabled. We are not really sure what happened next but I think a jury of the 
offending user peers addressed the issue…. The rogue AP never appeared again…. 
and all the ports were re-enabled.

I'd lean more towards a kid being funny but having now clue what a channel is. 
Some wireless routers come from factory with settings like this. Or the user 
clicks on options that doesn't understand.

I've seen other names such as "get off my internet" or "FBI surveillance"
