Re: [WIRELESS-LAN] Performance improvements from hallway to in-room

[Dan Lauing]

We don't get complaints about APs in the rooms, but I have thought about
starting a rumor that the real danger is ad-hoc/wifi direct printers. After
all, they're blasting at 20dbm out of the box compared to my whisper-quiet
APs. Parents that care would either take those things back to Best Buy or
have their child connect it to *our* network like a responsible adult. :)

We did before/after student satisfaction surveys and found a 50%
favorability improvement (35-85% good or better) moving to an
every-other-room in-room architecture vs hallway AP's.

We did just have our first request for AP removal though. Thankfully, our
Housing staff is accommodating.

Re: [WIRELESS-LAN] Aruba Wi-Gi 6 APs

[John Rodkey]

This was true of our Aerohive deployment as well.  The Windows drivers were
not compatible with 802.11ax, and SSIDs were invisible to them, and not
able to be connected to even if specified.
We were forced to revert our APs to 802.11ac mode because of the impact it
had.  The trouble is that even though the patches are available, they
aren't pushed out because they aren't security or otherwise urgent.
Bottom line is that the problem is with the user device, but naturally IT
is blamed for the failure nonetheless.  Welcome to IT!

We had the 515’s at 2.5 Gig initially, but ran into a PoE issue on that style 
port, so right now they are back to a Gig until that is resolved.

We have over 100   515s and 535s deployed.  I have disabled the HE (ax) radio 
for now due to  legacy client issues. (intel)   I’ve seen this with other ax ap 
vendors so not just aruba thing.  Yes updating drivers has fixed but it’s 
really hard to instruct end user to go download drivers when the device doesn’t 
see any ssid even open guest one.   We weren’t seeing many ax clients so 
disabling this phy isn’t really huge issue for us today.

We have been very pleased with the performance of the system from client 
perspective.  But going from 802.11n 2ss aps to 802.11ac 4ss with 5ghz in room 
design probably has more to do than model of the ap.  Now the 8.x gui in aruba 
is another story.   Learning the ways of the mm cli will get you much farther 
than the buggy gui that is in the 8.5 train.  I’m on the latest 8.5.3 code as 
well.

We just did a migration to the Aruba 535’s across campus (700+ APs) and have 
had some window intel wifi driver issues, but so far no issues with Apple 
devices. I think we have 1 or 2 11ax clients :)

RE: Performance improvements from hallway to in-room

[Christopher Brizzell]

Just be ready for some amount of backlash from an angry/ignorant parent. Every 
year (including yesterday) we have parents contact us saying we needed to 
remove all APs from bedrooms because of the health risk to the students living 
in those spaces.

Thank you for the information, however. Any amount of proof to help solidify 
our decision helps.

Subject: [WIRELESS-LAN] Performance improvements from hallway to in-room

All:

We all know that moving from hallway deployments to in-room deployments pays 
dividends.  This summer we started doing some re-cabling work on smaller dorms 
to move from hallway to in-room.   We also went away from Aruba higher 
performance APs to the hospitality APs for these locations.  Even though the AP 
cost is significantly less, the cabling costs made this move a premium option.  
Nonetheless, thanks to data provided to us from Nyansa Voyance, we are able to 
clearly demonstrate to Housing that these funds were well spent.  After the 
changes, these dorms went from some of the worst performing locations on campus 
to some of the best.  When you look at the graphs below, the Y axis is 
percentage of users that are affected by poor wifi performance (I believe 
Nyansa measures this as clients that experience a 25% retransmit rate from the 
AP to client).  With Nyansa, it determines behavior on usage level.  So when 
you see the dashed line, it means that usage was below or above the threshold 
during that time frame.  I picked the usage level that would show the most 
complete picture, but going from low/medium/high all show the same improvement 
levels.

Is anyone running multi-gig out to their APs or just a 1Gbps link?

RE: [WIRELESS-LAN] Aruba Wi-Gi 6 APs

[Oakes, Carl W]

We’ve got a new  5 Story Science building fully deployed with 515’s, so far so 
good.  We had the same driver issue, Intel AC-7620 was the card in question.  
Semester is two weeks in and no complaints.Actual benefits, eh, I think 
I’ve seen two clients connect as WiFi6 (HE). J   Hope to see more as clients 
become available. I like the new mounting system for the AP’s.We have 
one small building / isolated that we plan to drop a 555 in to see how it 
behaves.

The good news is that they work, so by deploying now you have a little more 
future proofing, ie, not buying older model AP’s.

We did have a PoE problem with the AP’s and switches (Alcatel-Lucent), still 
under review, but we were able to mitigate it for now.

We also moved to Aruba v8 (8.5.0.2) this summer, and let AirMatch choose 80 Mhz 
channels if it wanted too, which it did for a lot of the AP’s, that too has 
gone well.  Keeping an eye on that one though.

This is one reason why I don't think that game streaming will happen
anytime soon if ever. The only place that you can possibly do this is a
university because there is rarely if ever a bandwidth cap there. Every
home user that I know of has a bandwidth cap that they would speed right
past within 2-5 days.
