Re: [WIRELESS-LAN] Wireless Only in Student Housing?

[Jeffrey D. Sessler]

Dan,

We were one of the first colleges nationally to provide wired “gigabit to the 
pillow” in all of our residential halls. Today, those residential halls are 
WiFi-only and we’ve abandoned the wired, going as far as to remove the copper 
doing renovations.

Done well, with dense coverage in-room as well as in hallways, common spaces, 
etc. there are only outlier cases where a wired port would be desirable.

I knew wired networking in Residential halls was at an end when a number of our 
first-years ask, “What’s an Ethernet Cable?” They’ve spent there 
Internet-connected life on wireless devices, so the term and concept is now 
foreign.

Hi All,

We are looking into building a new student housing building and are considering 
going Wifi only for network connectivity. We were wondering if anyone else has 
gone the route of only allowing network connectivity via wireless. If so, can 
you share your experience, lessons learned, and advice.

The main reasons we keep running one port per pillow is gaming and research
projects.

Students want their gaming PCs to have wired Ethernet, and they sometimes
need to transfer large files for research or classwork.

As a result of these factors, we'll likely keep installing the drops to
each room, even if we do not connect them except by request.

Re: [WIRELESS-LAN] Wireless Only in Student Housing?

[Joel Coehoorn]

I don't see a need for port-to-pillow anymore, but I believe it is still
helpful to have wired jacks in common spaces for the building and common
rooms within suites.

Part of the belief stems from the idea there is a difference between what
students' natural behavior would be and what it will be if you ask them to
do something. In this case, students have grown up wireless and very few
are naturally inclined to even think about plugging in a device. However, I
have found you can encourage students to connect smart TV devices via the
wired port in the common space when possible, and many seem to understand
this can really help throughput for everyone once they hear the message.

I don't have stats at this point in the semester for exactly how much ports
are used, but I know it's helped in previous terms. This wouldn't happen if
we didn't make the ports available and also communicate to students how
they benefit from using them.

RE: [WIRELESS-LAN] Wireless Only in Student Housing?

[Enfield, Chuck]

I don’t want to hijack Dan’s thread, but I wouldn’t mind adding to it if he 
doesn’t mind.

I know from previous threads that lots of schools have gone Wi-Fi-only, and 
issues are minimal.  But, as an institution that has both wired and wireless 
enabled throughout the residence halls, about 15% of our residents still plug 
in.  It was easy for us to do both because we were really late to provide 
Wi-Fi, so our legacy wired network is still serviceable.  At some point in the 
next couple years we’ll have to decide whether or not to replace it.  That 
requires an assessment of the value proposition.  15% use seems to suggest that 
there’s still significant value in providing wired connectivity, but I’m not 
sure it satisfactorily answers the question.  It’s safe to assume that some 
users really want that wired connection for good reasons, and other users who 
prefer a wired connection if it’s available, but really wouldn’t miss it if it 
wasn’t.  It’s to determine how many each make up that 15%.

I’m curious to hear from institutions that provide wired connections upon 
request.  If you do that, how many get requested?  Is it free, or is there a 
charge?  If a charge, how much?  …and anything else illuminating you can 
no-doubt contribute.

Re: [WIRELESS-LAN] Wireless Only in Student Housing?

[Joseph Bernard]

We just opened a building with a wallplate AP in every room.  Any wired 
connections needed are plugged into the jacks on the bottom of the wallplate.  
Things seem okay so far but we haven’t made it to our worst day which is the 
first Tuesday of semester which causes the most stress on our wireless.

RE: [WIRELESS-LAN] Wireless Only in Student Housing?

[Linchuan Yang]

Dear Daniel

We have done this to most of our residence buildings for more than three years.

Before, we gave them wired connection and IP phones. We found that many jacks 
in the rooms were broken, and we spent a lot to do the maintenance on the jacks 
and phones.

Three years ago, we concluded that almost every student in the residence has a 
cell phone, and they do not need the wired connection anymore because they are 
using laptops and mobile devices. So we disabled all of the wireless 
connection, and only enable the jacks if they have special request. This also 
help us to reduce the number of switches in the residence.

You’d better make a good pre-site survey for the wireless coverage in your new 
building ( I spent almost two weeks to do the site survey in the construction 
stage of our new residence), and leave some buffer because after students 
moving in, the furniture and human body can block or absorb some signal. And it 
will not be easy to add more Aps later.

In the past three years, we do not have any major problem for the network 
connection in the residence except the interference from personal rogue routers 
and wireless printers.

Hope it can help for your decision.

Have a good weekend.

Re: [WIRELESS-LAN] Cisco - Field Notice - 70253 - Wireless Client Fails to Associate: AID

[Jeffrey D. Sessler]

It’s important to separate marketing from the reality of how the technology 
functions.


  *   Band Steering – Cisco didn’t say it was impossible, what they said was 
that the client side of the equation was so fraught with issues that the 
feature would lead to greater problems, especially in diverse ecosystems such 
as education. That totally played out here, where the Aruba feature had to be 
disabled because it was causing a lot of issues.  In the central library, I 
could watch as Macs (in particular) would be bounced around like a hot potato. 
Even today, it’s a lot better, but clients are far better at making the right 
decision, so leaving the feature off, be it Cisco or Aruba, is a prudent idea.
  *   Spectrum Monitoring – Again, Aruba is/was dependent on what the 
off-the-shelf chipset is capable of. Perhaps this has improved in the latest 
AP’s, but we (and respected others in the field), found them rather blind to a 
lot of spectrum data that the CleanAir Cisco devices saw clearly – and 
significantly faster at detection of items the Aruba also saw. CleanAir AP’s 
have a dedicated equivalent of spectrum expert on them – they don’t need to use 
the client radios to do the work. It’s always on, always looking.
  *   Bugs – I don’t know the specifics on the current issues, but I know 
they’ve run into a number of show-stopper problems in the past. The controllers 
and APs are fairly new (24 months), so it’s not because they are running 
something unsupported. The companies you mention were customers before HP 
purchased Aruba. Given what the college’s here have expressed since the change, 
it would be difficult to speculate on their satisfaction under the new 
direction. It’s sort of like saying Cisco has 45% of the WiFi market, so with 
nearly a three-fold advantage over their nearest competitor, it’s surprising 
Toyota would go with a distant 2nd. Then again, companies often make decisions 
based on non-technical reasons e.g. joint marketing incentives, or because the 
alternative is a close partner with a competitor.

Aruba introduced client band steering before we became their customer in 2008. 
At that time Cisco said band steering was not possible. Aruba has had spectrum 
monitoring since before Cisco’s CleanAir technology. We know who is following 
whom. That is why we made our choice.

Aruba has had ap preload for years but this is hands off seamless automated 
updating of controllers & APs.
.

I am very interested in what Aruba bugs have not been addressed, assuming they 
were running supported code. We work very closely with their support and they 
insure our needs are met. I am sure large companies like Microsoft, Google, & 
Toyota would not use Aruba if the support was lacking behind others.

With Aruba (& Cisco) one needs to move carefully when updating to insure the 
new version meets your stability requirements while fulfilling your needs.

It’s great to hear Aruba is adding features such as “automated RF management” 
that Cisco has had for over a decade. In another ten years maybe they’ll catch 
up to Cisco’s CleanAir technology?  :D

In all seriousness,. if you’re talking specifically about AP updates, cisco has 
had AP code pre-download for years, resulting in between 2 to 4 minutes 
downtime when rebooting a multi-thousand AP controller. Not hitless, but low 
impact for sure.

If you make use of Prime 3.3 or above, you’ve got Rolling AP Upgrade, ensuring 
that AP’s are updated and rebooted in defined groups so that clients are 
minimally impacted i.e. they roam to another AP while an adjacent is being 
updated. It’s not hitless since the client must roam, but it’s as transparent 
as you’re going to get.

In my opinion, the only way we’re going to see better results for enterprise 
WiFi in EDU will be as customers transition to cloud-based managed-services. In 
this scenario, the vendor gains significant visibility on everything deployed 
in the field and isn’t waiting for a customer to decide to open a case and do 
all the necessary log/data collection e.g. Meraki.

The campuses in our consortium that had been on Aruba have been migrating to 
Cisco this summer. Since the purchase by HP, support and innovation has waned, 
with bugs they’ve hit not being addressed. 

RE: Site Survey Tool (laptop/tablet/2-in-1)

[Thomas Carter]

We have something similar, only dual boot Windows 10 / Ubuntu (for promiscuous 
mode packet capture). While currently on a standard laptop, I really like the 
usability and flexibility of the latest 2-in-1s as compared to something like a 
Surface Pro (we have a few of those in users' hands) or a traditional laptop.

Hi Everyone,

I was just wondering what was everyone's weapon of choice for performing site 
surveys in terms of laptop/tablet/2-in-1. I'm currently using a Surface Pro 2 
to run our Ekahau site survey software and it's performed very well for me over 
the years. But, alas it's starting to show its age, so it's time to look for 
its successor. Obviously based on my experience a Surface Pro 4 would be a 
logical choice, but I'm interested to hear what others are using. So over to 
you...

Thanks

RE: [WIRELESS-LAN] Cisco - Field Notice - 70253 - Wireless Client Fails to Associate: AID Error

[Lee H Badman]

I can't say I love ClearPass (we use it) and the recent relicensing felt very 
much like yet another revenue grab. Not sure the grass is totally greener 
anywhere. If Mist would tone down the buzzword-driven marketing and start 
highlighting real-world value proposition and case studies of very large 
accounts, that could be interesting. Likewise, if Ubiquiti could get their 
enterprise approach together and stop feeling so wonky on the company side, 
they too could be interesting. I'll admit there where we use cloud-managed in 
our branches, I LOOOVE no keeping up controllers or NMS systems, as I've 
had years where I have spent months dealing with bugs on both. 

I do wish every WLAN company CEO would remind themselves that there are end 
users at the end of the string out there, and that stability trumps feature 
bloat and that phrases like "our new blood-sucking licensing insures you have 
access to INNOVATION!" just sound desperate. (Oh, and I want a pony, too!)

My understanding of the “automated RF management” part is directly related to 
the upgrade process (and not DCA/TPC, as you’re suggesting, which Aruba has had 
for some time).

It splits the APs automatically into groups based on their channel assignment 
(since, given similar approach as DCA, this gives a rough estimation on “APs 
that are overlapping each other” — could also be improved in the future using 
signal strength an AP sees other APs). 
It then moves clients off of one of those groups (making them join other, 
adjacent APs), reloading those clientless APs into the new software version, 
and then moves clients back when it moves onto the next “channel group”. 
Cleanse and repeat until all groups are done, giving you “zero downtime”.

This is at least how it was last time I read about it, and is by far superior 
to the way Cisco does it (where you manually have to fiddle with groups within 
Prime — and that’s without talking about Prime itself…).

The Cisco-solution also requires a separate controller to do this, whilst Aruba 
uses it’s redundant controller by automatically handling “splitting” the 
HA-pair (by upgrading one of them, moving the APs according to the “channel 
groups”, and then finally upgrading the last controller).

The “equivalent” with Cisco would be to split your HA pair manually, move all 
APs to one of them, upgrade the other, move them using the 
rolling-AP-group-thingie in Prime, then upgrade the last, and finally join them 
back as a HA, causing significantly more downtime than a normal Cisco upgrade 
process. Or you could buy a completely separate WLC to achieve this, but that’s 
somewhat a waste of money if you already do HA/SSO (and buy WLCs in pairs).

I’ve never managed to do less than ~400 seconds on HA/SSO-enabled 8540s with 
3k+ APs. That’s “a lot of time” many places (maybe not edu, but for sure in 
healthcare or other mission-critical businesses), which would be reduced to 
whatever time it takes for a client to re-associate after being “kicked” off 
the network (so time depends on the client, but would probably be sub-1s in 
many cases).

RE: Cisco - Field Notice - 70253 - Wireless Client Fails to Associate: AID

[Osborne, Bruce W (Network Operations)]

Aruba introduced client band steering before we became their customer in 2008. 
At that time Cisco said band steering was not possible. Aruba has had spectrum 
monitoring since before Cisco’s CleanAir technology. We know who is following 
whom. That is why we made our choice.

Aruba has had ap preload for years but this is hands off seamless automated 
updating of controllers & APs.
.

I am very interested in what Aruba bugs have not been addressed, assuming they 
were running supported code. We work very closely with their support and they 
insure our needs are met. I am sure large companies like Microsoft, Google, & 
Toyota would not use Aruba if the support was lacking behind others.

With Aruba (& Cisco) one needs to move carefully when updating to insure the 
new version meets your stability requirements while fulfilling your needs.

It’s great to hear Aruba is adding features such as “automated RF management” 
that Cisco has had for over a decade. In another ten years maybe they’ll catch 
up to Cisco’s CleanAir technology?  :D

In all seriousness,. if you’re talking specifically about AP updates, cisco has 
had AP code pre-download for years, resulting in between 2 to 4 minutes 
downtime when rebooting a multi-thousand AP controller. Not hitless, but low 
impact for sure.

If you make use of Prime 3.3 or above, you’ve got Rolling AP Upgrade, ensuring 
that AP’s are updated and rebooted in defined groups so that clients are 
minimally impacted i.e. they roam to another AP while an adjacent is being 
updated. It’s not hitless since the client must roam, but it’s as transparent 
as you’re going to get.

In my opinion, the only way we’re going to see better results for enterprise

Aruba has its problems too, but they try to minimize them. Do not forget that, 
for many years, Aruba was a wireless-only company. Their wireless needed to 
work for them to remain profitable. For Cisco, wireless is just another product 
line in a large portfolio.

As a result of the lack of QA, we removed all 1000 of our Cisco AP's and moved 
to Aruba.  Since then, we have had zero problems.  

Cisco really needs to get their stuff together, their Wireless has not been an 
Enterprise level product, in my opinion.

RE: Cisco - Field Notice - 70253 - Wireless Client Fails to Associate: AID Error

[Osborne, Bruce W (Network Operations)]

18 months ago I experienced a version upgrade on the active system at a 
conference. 

In our initial failover testing here, we had a client set up doing a continuous 
ping to a target. We took our network from4 controllers down to 1. The AP & 
client roamed seamlessly such that not one ping was dropped.

My understanding was that one of Aruba's large clients demanded a system with 
no downtime.

We can also, if desired, run different code versions within the same system.

You say “zero downtime”. Aruba says “hitless”. None of those are true.

Don’t misunderstand; it’s far better than what Cisco has, but the system 
disconnects the clients from the AP side of things, and hence, from a client 
perspective, it’s not “hitless” or “no downtime”. They just suddenly get 
disconnected, and they have to reconnect. It’s not the clients decision to move 
to a new AP.

Would I like this on Cisco; absolutely. I’m not holding my breath, though.
