RE: [EXTERNAL] Re: [WIRELESS-LAN] Client roaming

[Enfield, Chuck]

We design to -60dBm as measured by a Fluke Aircheck,  That usually works out to 
around -63 to -65 on a MacBook and -65 to -68 on a tablet or phone.  I’m sure 
there are a few outlier devices that measure it as weaker than -70, but until 
recently it was clear that those were outliers.  If you did a packet capture 
where the coverage was up to our spec you would hardly see any probes.

We were already planning to up our standard to -55 as we deploy 11ax, but 
getting to that in our res halls means an AP in every room.  We have every 
third room right now (each AP is expected to cover through one wall).  We can’t 
afford to triple the number of APs right now, so it’s important that we find 
another solution.  Jimmy’s suggestion of a 5GHz only SSID may help, but based 
on what I know about our coverage I think we’d still have significant issues 
with roaming between different 5GHz radios.

Agreed, an iOS device at -65 starts roaming and acts wonky from time to time.  
The issue we run into a lot is, which iOS device do you design for?  Do you 
design with the iphone 11 or 10, or do you design for the frst SE, 6, or 7 that 
are four or five years old now?  With iOS devices able to get code updates for 
4 years do you still consider them a relevant device on the network, when you 
might see only a handful of them.  I went back through my tickets earlier 
today, and did notice that most complaints are from macOS and iOS devices.  As 
the wireless cards get better at what point  do you start eliminating the older 
equipment off of your network when you are BYOD?

On thing to keep in mind is that iOS devices start behavior poorly when they 
have no good option above -65.  That’s the threshold they prefer 5GHz and when 
you combine that with “hallway design” and “band select” you are asking for a 
bad time.

Scenario:
Client doesn’t see 5GHz above -65.  2.4Ghz looks better, client tries to 
associate and bandselect tries to send them back.  Client doesn’t think 5GHz 
meets its requirements, tries to associate on 2.4Ghz.  Round and round they go.

If you need band select for devices like iOS that prefer 5GHz, you likely don’t 
have enough 5GHz coverage, and trying to force them to 5GHz only results in 
issues.

A better approach is to have at least 6db of transmit power more on 5GHz than 
2.4.  This makes 5GHz generally look more attractive so clients naturally pick 
it, band select not needed.  You can easily do this with TPC min/max settings.

Also keep in mind when looking at your survey reports.  -65 is as measured by 
the device, not your fancy sidekick or aircheck.  Figure you need an extra 
7-10db delta to overcome the limitations of some mobiles devices.  That puts 
you -58 to -55 as measured.

Maybe it is just us, but we have lots of places where a 12dB delta is hard
to achieve when designing for dual 5G radio coverage at -65 dB.  Clients
end up skipping an AP (or two) before actually roaming.  Not to mention use
case and behavior differences between laptops and mobile devices like
phones and tablets.  You might notice on a laptop Zoom session, maybe not
with an iPhone VoWi-Fi session.  Our focus was on VoWi-Fi, thinking it was
the more challenging thing to tackle.   Remote learning is challenging
those assumptions.

Best thing you can do for clients is have a 5GHz only SSID.  We moved over
the summer to this with our main 802.1x network and it has fixed a ton of
these roaming issues and complaints of performance.  Basically take the
decision making out of the hands of the client, give them only one band to
choose from.  Band Select / steering may work but can lead to a lot of
users issues as roaming can break if the client doesnt take the hint to use
5GHz.  Transitions with real time applications like voice can be negatively
affected.

For those on our campus that have 2.4GHz only devices, we offer eduroam in
both bands and have them use that then use AAA override to place them in

Re: [WIRELESS-LAN] Client roaming

[Mallon, Jason]

We are seeing a lot of this on the 1815w’s.  We are getting complaints in dorms 
that have 9115s and 2802s as well.  I am going to fix the building with the 
2802s tomorrow to see if that helps them any.  Same thing we get 1 complaint, 
but everybody on the floor is having the issue.  I am not hearing the 
complaints in academic areas, either and I have a lot of ceiling mount APs in 
those areas.

Clients do roam aggressively, but I am confused as to why they are roaming at a 
-55 5 radio to a -70 2.4 radio.  The client cannot be thinking that connection 
is better.

Thanks,
Jason Mallon | Network Engineer III

A lot of devices roam aggressively once RSSI falls below some threshold level.  
It was -70dBm for a few years.  It started on Apple products and was soon 
copied by Samsung, Microsoft, and many others.  I’ve long treated roaming 
issues where the 5GHz signal is around or weaker than -70 as coverage problems, 
and when we improved the coverage the roaming problem went away.  This year 
we’re seeing the problem where the 5GHz signal is clearly better than -70.  Not 
sure if the threshold changed on the client devices or if something else is at 
work here, but something seems different this year.

The 9800 does have a conversion tool for the aireOS controller configs and does 
most everything but the encrypted stuff.

Even if building from scratch, running the existing config through the tool may 
help in understanding how all the pieces work, including the equivalent 
commands between the two.

When building from scratch, it can be helpful to forget about what you had, and 
treat it as a different vendor product. It’s a rather radical change, but far 
more powerful, and despite many will initially ignore the built-in wizards, 
they are pretty powerful.

I agree there are certainly some new practices going on, with students
holed up in their rooms on Zoom meetings all day!
Specifically on the reports we're getting, we're seeing multiple platforms
(everything from MacOS, iOS, Windows, Androids) roaming around to the
nearest 2-5 ap's on a regular basis.
It's usually from a student who doesn't have an ap in their room - we have
Cisco 1810W's approx every other room.
Not hearing any reports of this in NON-residential areas, which are all
2700-series mostly out in hallways etc
Less roaming options, makes sense... hmm, maybe shut off half our 1810W's
in the dorms? :D

RE: Client roaming

[Jeffrey D. Sessler]

My personal belief is that even today, technologies like band select just 
compete with the secret sauce on the client side, and are subject to problems.  
Every time I've experimented with it, I turn it back off (cisco and aruba), as 
your success is often short-lived until the next device OS or driver update.

Specific to 8.10, TAC and the BU have recommended the interim 8.10.139.43 until 
8.10 MR4 is out. As such, you may want to take a look at the release notes to 
see if there are any defects registered that relate to the issue.

Subject: [WIRELESS-LAN] Client roaming

Wondering if anybody else is seeing this.  We currently have devices doing a 
lot of roaming between 5 and 2.4 radios, especially in the dorms.  I would not 
think anything of it normally, but they are moving from a -52 to -58 on the 5 
radio to a -75 or worse on the 2.4 radio.  This doesn't seem to matter what 
SSID they are connected to.  Band select is enabled on all SSIDs.  We are 
running Cisco 8540 WLCs on 8.10.130.  Most of the complaints are coming from 
the dorms, so I am not sure if it is happening on our other controllers with an 
older code level.

We are in the process of upgrading our wireless from a Cisco 8510 to a Cisco 
9800-80. I wanted to query those on this list who have already gone through 
this process about any lessons learned that would have been nice to know before 
transitioning your existing AP inventory that is compliant with the new 
hardware. I am building the configuration for the 9800 from scratch and it has 
been a challenge learning the new concepts for configuring this type of 
controller, so I was hoping to see what others have learned from the 
experience. Any thoughts would be appreciated.

RE: [WIRELESS-LAN] Client roaming

[Enfield, Chuck]

FWIW, I've been reluctant to assume this is a new problem.  Usage patterns have 
changed in the dorms and people are spending much more time using real-time 
protocols than ever before.  Those protocols make brief connectivity issues 
very noticeable.  It's quite possible we've always had these problems, but they 
rarely bothered users enough to make them open trouble tickets.

We're an Aruba shop and have noticed similar behavior.  We're having more 
incidents of intermittent connectivity issues this year than in previous years, 
and most of those clients are making questionable roaming decisions.  It's been 
really prevalent with iOS and MacOS.  Much less on Windows and Android.  
There's always been problems with picking a good radio when those devices first 
connect, but, historically, once they were steered to a good 5GHz radio they 
stayed there.  They're not staying there this year.  We haven't figured out why.

Wondering if anybody else is seeing this.  We currently have devices doing a 
lot of roaming between 5 and 2.4 radios, especially in the dorms.  I would not 
think anything of it normally, but they are moving from a -52 to -58 on the 5 
radio to a -75 or worse on the 2.4 radio.  This doesn't seem to matter what 
SSID they are connected to.  Band select is enabled on all SSIDs.  We are 
running Cisco 8540 WLCs on 8.10.130.  Most of the complaints are coming from 
the dorms, so I am not sure if it is happening on our other controllers with an 
older code level.

We are in the process of upgrading our wireless from a Cisco 8510 to a Cisco 
9800-80. I wanted to query those on this list who have already gone through 
this process about any lessons learned that would have been nice to know before 
transitioning your existing AP inventory that is compliant with the new 
hardware. I am building the configuration for the 9800 from scratch and it has 
been a challenge learning the new concepts for configuring this type of 
controller, so I was hoping to see what others have learned from the 
experience. Any thoughts would be appreciated.

Client roaming

[Mallon, Jason]

Wondering if anybody else is seeing this.  We currently have devices doing a 
lot of roaming between 5 and 2.4 radios, especially in the dorms.  I would not 
think anything of it normally, but they are moving from a -52 to -58 on the 5 
radio to a -75 or worse on the 2.4 radio.  This doesn’t seem to matter what 
SSID they are connected to.  Band select is enabled on all SSIDs.  We are 
running Cisco 8540 WLCs on 8.10.130.  Most of the complaints are coming from 
the dorms, so I am not sure if it is happening on our other controllers with an 
older code level.

Thanks,
Jason Mallon | Network Engineer III

Re: [WIRELESS-LAN] Transitioning from older controller to new controller

[Michael Usher]

Hey Don,

We're going through that process at the moment.  We've migrated most of our
config across and we're running about 280 x 9120 APs with 400 client
devices on it so far (mostly dorms -- about 1/3 of our overall on-site
device count).  I'd be happy to do a Zoom session with you and show you how
it looks at our end.  We're running both in parallel right now, slowly
migrating as we upgrade buildings.  New is 9800-40 on 16.12.4a, old is 8540
on 8.5.160.  Email me directly - mus...@ucsc.edu.

Re: [WIRELESS-LAN] Mac wireless issue

[Anthony Croome]

We also have plenty of apple laptop users complaining about wifi performance.  
We have at least one macbook user who seems not to be able to connect to 
u-nii-1 channels and falls back to 2.4GHz.  One suggestion I read today was to 
'turn off unlock with Apple Watch and reboot'.

What channels are the impacted AP’s running on?



A few weeks ago I had a similar issue (Cisco wireless), My Mac laptop would 
attach to our WPA2 network no problem – auth was successful (5 GHz), but would 
never get an IP. If I walked the Mac laptop (running Catalina) into rage of 
another AP (also 5GHz), it worked perfectly. Same switch, same AP type, with 
the only difference being the channel the AP was on. I could replicate this in 
another area, where a user reported a similar issue.   I don’t have my notes in 
front of me, but I believe the problematic AP’s were on unni-3 channels, and 
the ones that were OK, were not.  With COVID, students remote, and work from 
home, I’ve not had time to go back in to the campus and really drill into it.



There had been no reported problems when our campus closed in March, and no 
changes to our wireless deployment since that date.

Greetings,



We are seeing a weird issue on our campus and hoping some of you may give us 
some ideas to check on.



Background: We are using Aruba wireless controllers/APs (sadly, no airwave). 
All buildings are using the same VLAN ID for the wireless subnet, but each 
building has their own subnet for wireless. All APs are configured in the same 
AP-group. We have an open wireless network and not using any NAT (public IPs 
are being given out). IPv4 only.



A lot of our Mac users, though not all, when trying to connect to wireless, 
they are able to connect to the AP, but are receiving a "No IP Address" 
message, and therefore cannot access the Internet. Once they leave this 
building and go to any other building on campus, they do not have an issue 
whatsoever.



We have tried to manually configure the IP address, but still the device is 
unable to access the Internet (cannot even ping the GW). After removing the 
Wi-Fi option in Network Preferences and then re-adding, the device is able to 
get an IP from DHCP server, but is still unable to pass any traffic. We have 
tried rebooting the laptop, completely removing wireless network and 
reconnecting, and have tried booting in safe mode. Nothing seems to be working. 
If we connect using an ethernet cable in the same building that we're having 
wifi trouble in, it works with no problem. Config for the wireless subnet in 
the affected building is the exact same as config in all other buildings 
(except the subnet, of course). All buildings are using the same DHCP server.



This seems to only be happening with Macs, not any Windows machines that I am 
aware of, nor do we have any problems with other Apple devices. And like I 
said, some Macs are having the issue, others are not. We only started seeing 
these problems within the last 2-3 weeks. The only difference we made in the 
affected building is giving it a larger subnet over the summer.



We are working with our Aruba SE who is reaching out to TAC for us, but wanted 
to reach out to you guys for any other possible insight or ideas. Thanks in 
advance!
