RE: [WIRELESS-LAN] Move In/Opening Week- Any Problems?

[T. Shayne Ghere]

Here’s our setup



Running 8.2.160.0 on a pair of 8540 in HA mode

796 1810w

472 3802i

Mix of 1142, 702 totaling 220 that will soon be replace with 3802i

Total AP’s will be close to 2015 when new wiring is pulled



Home grown registration for one SSID that’s used for devices that won’t
work on secure or web-auth networks



I’m running Flexconnect on the wireless along with an Rlan for the wired
ports for the 1810w’s (dorms) and local switching where applicable.



So far, we have identified 5 bugs with the 160.0 code which Cisco is
working on.  They aren’t service impacting but more of a pain than
anything. (Kernel panics and watchdog resets)



We have identified the Lenovo Yoga series laptops (and other models from
Best Buy) having issues with enterprise networks with no solution since the
last Windows 10 update.  If the users go an buy a small form factor wifi
adapter, everything works.   Without it, they aren’t able to connect to our
secure network and open networks are slow.



Dell laptops seem to be the most stable followed by Macbook Pro’s.



We have already surpassed most connected clients from last year on the
second day of classes this year.  I’m seeing a LOT of wifi enabled TV’s,
IoT devices (ugh), tablets, phones, smartwatches and wireless
cameras/doorbells for rooms.



Our biggest concern is the amount of wireless printers that have shown up.
We don’t allow wireless printers on our network, but when trying to get the
wireless cards shut off for each one is becoming a problem.



If anyone is handling wireless printers differently, I’d be interested in
talking offline with you.

It might be beneficial to share notes in case other schools are hitting

faring with back-to-school?



On this end, we are doing OK halfway to our expected total daily peak
clients (we’re at 15K now high water mark).



Our significant WLAN-related changes since end of Spring semester

· Running 8.2.151 on our 8540s

· Significant quantities of Wave 2 APs

· ISE as RADIUS (only, no NAC, no onboarding)



No changes to:

· our guest WLAN (Clearpass/an Aruba controller pair)

· onboarding (Cloudpath Wiz)

· overall topology

· open network in dorms for gadgets

· non-use of AVC, it crapped out and never got solved after
hundreds of hours with TAC



Fears:

· We haven’t yet hit the scale that will reveal problems with any
of the newer stuff listed above



Anyone else care to share?

RE: [WIRELESS-LAN] Cisco 1810W subtleties

[T. Shayne Ghere]

Depending on how your network is setup, this may not be for you.



We just deployed 700+ (all dynamic Vlans) using Flexconnect and it works
flawlessly.  We have 18 dynamic Vlans for our dorms/apartments as well as
10 for Academic/Administrative buildings.



I’d suggest contacting your Cisco Rep and talking to them before purchasing
an AP that’s assumed to do what the 702 (non-wave2) AP’s do.



We have over 200 devices plugged into the built-in switch ports and 5000+
wireless clients utilizing the 1810’s.   No complaints here…but we tend to
write our own software that takes care of all the backend
registration/authentication.



Good luck!

If you are planning to buy the Cisco 1810W and you are planning to use the
built-in switchports, I highly advise you to look at the deployment guide
and learn about the subtleties of enabling local switching. Don’t expect
for this AP to work just like the Cisco 702W. Cisco managed to make its
configuration a little more “fun”.



Basically, in order to enable local switching, you have to configure the AP
for FlexConnect. ND you also have to configure a WLAN and AP groups to
make sure your switchports map to the right VLANs. Yeah, it’s like that.
Have fun.

RE: [WIRELESS-LAN] Per room wireless

[T. Shayne Ghere]

We’re getting ready to deploy almost 900 of the Cisco 1810W (hospitality
AP’s) with the cradles in the residence halls.  We’re using 802.1x in order
to allow students to make use of the additional LAN ports in the cradles.



Our design is a high density 5Ghz deployment with some 2.4Ghz radios turned
on where needed (sparse).   With the buildings mostly comprised of
brick/rebar, the AP’s will be in every other room staggered across hallways.



In our suites, one is being placed in the common area which easily reaches
the 2-3 bedrooms.   My design is based on 25% power utilization which will
compensate for any AP’s that may fail during the evening.   The Controllers
will automatically adjust power levels up to 100% in the case of failures
on a floor.



Sentinel and Cisco has been great helping with the design and planned
implementation that we are doing right now.



Best of luck!

For refurbishments we specify one high level data point per room so that we

locations are determined first by predictive design and then later using

power levels and luckily we've not had to move or add any APs yet.

Cisco ISE

[T. Shayne Ghere]

Good morning,



Currently we have a home grown wireless registration system in place that
is becoming obsolete.  We are getting ready to refresh our Cisco AP’s, and
I’m writing to see if anyone has any positive/negative issues in using
Cisco ISE for individual “self” registration on your wireless network.



We also use WPA2/AES Certificate based security, but that is problematic
because of compatibility issues and devices that have no way of accepting
certs.   In talking with some Cisco Wireless Engineers, they recommend
WPA2/AES-PSK but we don’t have the manpower to set that up on every
device.   We also do not NAT any devices.



If you have any suggestions, or comments on using ISE and moving away from
Certs, I would greatly appreciate them.



Thanks

Shayne

RE: [WIRELESS-LAN] Access Point Failure Rate

[T. Shayne Ghere]

We have roughly 600 Cisco AP’s.  It’s a mix of the 1142 and 3702i’s, but
getting ready to triple that amount with all new Wave2 AP’s.



Our failure rate over the past 5 years is between 7-10 total.  Four were
from a lightning strike, but the others were the 1142N model and are in
areas that aren’t in the best environment for electronics.

RE: [WIRELESS-LAN] strange WLC behavior

[T. Shayne Ghere]

We moved off that as soon as the 8.0.120.x was out.  Make sure your AP's can
support 8.x code before you migrate to it.  95% of the issues we had on 7.4
and 7.6 went away once we moved to the new software.

If you're not running LAG, that will create problems in the 7.x software.

Not as buggy as 7.4.x... we ran 7.6 for a year quite happily.

All Cisco software releases are buggy... just depends on whether the bugs

How many authentications per second? Is it busier than usual?

Could be a case of the WLC reusing RADIUS session IDs which will totally
break stuff and is a know issue under high numbers of authentications.

Cisco have gone some way to fix this issue in the latest 8.x, but as far as
I'm concerned their RADIUS client design is overall still pretty bad.

So likely behaviour caused by some external factor, such as the above. But
could be anything like eap timers not tuned well, wireless issues at the
edge, etc. Or backend auth being slow.

Matthew

Great topic, and one that I deal with every day.



We are actively scanning Twitter and proactively reaching out to students
who voice dissatisfaction about WiFi services.



As we all know, WiFi is a lot like weather. A specific condition at a
specific time in a specific location. The location piece is a big part of
that equation.



You absolutely want to prevent public disclosure of private information -
particularly the geolocation of a student. Therefore, we attempt to engage
with them and endeavor to mutually follow each other on Twitter. By doing
mutually following each other on Twitter, a private channel can then be
established to talk about what's going on.



Once that private channel is established - we ask the student a few quick
triage questions [device/OS/location, etc.] We also ask them to use our
WiFi onboarding tool, which seems to take care of a majority of the issues.
We're currently using SecureW2 JoinNow for that task. It's been working
very well for our needs.



Once we have answers to the triage questions and have asked the student to
run the onboarding tool - we create a service center incident and hand it
off to them for further action. We make it clear to the student that
follow-up will happen via e-mail.



The service center incident is created using a template specific to
information gained from social media. We include the initial complaint and
conversation from Twitter in the work notes of the incident to give context
and clarify next actions needed. We may reach out to the student again via
Twitter to confirm resolution if the service center elicits no response or
further communication via e-mail.



*IMPORTANT!*

Some students merely want to vent. Face it, we all want (and need) to do
that sometimes!



When trying to establish engagement - you may get different reactions. Many
students are ecstatic that their complaint was noticed. Other students
ignore any attempt to reach out to them. Fewer react negatively - and some
realize that public tweets are actually seen and sometimes acted on.





Hope that helps!

RE: [WIRELESS-LAN] Video on the challenges of WiFi interference

I have to say, this was a rather well written video that covered it all for
the non-technical people (I call it dumbed down) and has flashy pictures
too!  It’s hard managing the wireless network when the upper administration

Wireless in Dorms

[T. Shayne Ghere]

Good morning.



Let me say first off, we’re nearly a complete Cisco shop other than our
Firewalls right now.  We are running 3 – Cisco 5508 Wireless Lan
Controllers and Cisco WCS.



The AP’s in the Dorm’s and Greek houses are all 1142N AP’s and have been
spaced accordingly by Cisco and by us during the introduction of wireless
in the Dorms, Greeks and Single housing.



We are having a heck of a time with all the interference that the students
bring with them making our wireless nearly unusable.  I know this topic has
come up in the past, but this year is one of the worst we’ve seen, and the
students are getting restless.



We have the ability to quarantine rogue Wireless clients, however according
to a recent Court case against a large Hotel Chain, it was decided that on
an open free wireless spectrum, we would be breaking the law in jamming it.



How have you addressed this issue?  I’m about ready to ask upper management
to remove the AP’s in all the Dorm buildings and let the students bring
their own AP’s if they want wireless.   Has anyone resorted to this?



Thanks for your input

Shayne

in the residences is to turn off the power. The stuff running off

has the ability to connect to other Sony devices, and Roku players that
used WiFi for its remote control.

This forks from the FCC just declared WLAN quarantine features illegal

interference. We've essentially had to resort back to physically locating
them and knocking on doors. We printed up an information sheet to slide
under doors, and communicate with residential staff, but it seems to have
mediocre success. We've also tried to communicate to students that the
cause of slow wireless is most likely interference from other devices in an
attempt to utilize peer pressure as well.  Unfortunately it seems to all be
very time consuming to track down and communcate.

RE: [WIRELESS-LAN] Windows 8 and Broadcom wireless cards

[T. Shayne Ghere]

Just a thought.



Is anyone using a different certificate other than Globalsign with their
ACS server?  If you’re successful in using the certificates on all Windows
8/8.1pro machines, could you please let me know what certificate you’re
using?



We’re using GeoTrust Global CA and GeoTrust DV SSL on our ACS server, and
I’m wondering if this is the root cause of it not working.  We have to
install the certificates manually when getting on our secure network and
since Globalsign is already installed, I’m wondering if this might be the
problem.



Thanks again!

We are a complete Cisco shop with about 500 1142N AP’s and 128 1231, 1232

they’re upgrading their computers.   All the new computers are working just
fine that come pre-installed with Windows 8.  Upgrade to 8.1pro and that’s

Wireless network cards running Windows 8/8.1 pro on a WPA2/AES network?  We
have students that are upgrading their Dell computers from Windows 7 to
Windows 8 and the cards stop working on our secure network.



They are prompted for 802.1x credentials, and the ACS server authenticates
them as well as the DHCP server handing out an IP address, but the computer
always states limited or no connectivity.



What is really weird is that we have a 1232AG radio and the card will
connect ONLY to the A radio, but not to the 1142N-A radio.   We are running
7.0.253.5 code because of the older AP’s on campus.   We did purchase a
separate controller for a test environment which we have running 7.4.110.0
now and it still won’t connect to the 1142n-a radios.



Trying to back the driver down to Windows 7-64 bit doesn’t work (won’t
allow it to be installed).



Any ideas?
