Re: [WIRELESS-LAN] Problems with new Apple Laptops

[James Andrewartha]

Not sure if it's the same problem, but I've got a 2012 MBA running
10.8.4 that's experiencing disconnects. Reading the logs it thinks it's
still got an 802.1x connection when it tries to reconnect to the
wireless, and it has a 169.254.x.x IP address. If I click Disconnect on
the 802.1x connection in the Network preferences, it fully disconnects
and loses its IP, but doesn't reconnect. The RADIUS server (Enterasys
NAC) logs show it was authenticating successfully many times, often as
little as 4 or 5 seconds apart, but it couldn't associate to the
wireless once it did.

The SSL certificate (actually, the CA that signs it) is already set to
always trust for everything.

I've upped my RADIUS timeout to 30 seconds (from 15), I'll see if that
has any effect.

Not sure why... but apple is unwilling to provide me any bug id specifics.
Our campus also doesn't have any support/engineering agreement with apple -
so that may  be part of it. they were kind enough to take in the info I
gave them... and they have reported back to me that the issues I see is
something imacting other big customers.

They believe its currently resolved in the latest beta of Mavericks
 (10.9) - but can't say if there will be a patch for earlier versions of
macosx.

Best option is to contact AppleCare - especially if your school has a
support contract - might be able to get more info than me.
If it helps my case # is 480081631.

Does anyone have an actual BugID with Apple that we can reference?  Before we 
go down the route of telling people that they need to change this setting in 
Keychain Access, it would be good to get an idea of whether Apple even 
considers this to be an official bug and when they might be able to fix it.

Re: [WIRELESS-LAN] Problems with new Apple Laptops

[Travis Schick]

Apple has confirmed that it is a cert validation delay...  and they do
respond... eventually - setting the dealy to 30 - at least allow the Macs
to eventually get online - vs getting stuck in the auth state and requiring
user intervention.

I don't think it should impact security holes... technically inside the eap
transaction its and SSL exchange when the cert is being used - at least for
PEAP and TTLS  but then yes... this shouldn't allow someone to steal
this cert/key and use to create trusted websites - since the browser is
using its on cert store/trust mechanism - i beleive these system trusts are
only for logins

That seems suboptimal.  Not just because you need to get your clients to change 
configs, but I wonder how that affects overall trust and if it opens you up to 
other holes.  For example, does changing that setting on the client mean that 
you won't be able to revoke that certificate?  What if your certificate and key 
get stolen and then used to set up a malicious site somewhere?  

Someone else can do that testing.  :)

Another vendor is recommending that a timeout value for EAP responses be raised 
from its default 5 second value to 30 seconds, since the Macs are eventually 
responding - it just takes a long time in some cases.

Re: [WIRELESS-LAN] Problems with new Apple Laptops

[Travis Schick]

I have found that this delay will go away if the cert used for WPA2 auth is
updated to also always trust for SSL.

find the cert in Keychain Access - then under trust settings add Secure
Socket Layer (ssl) - by default only EAP and X.509 is explicitly trusted

Unfortunately this is something that needs to be changed on each client
device - and one needs root/admin priv on the macbook to make the change.

Re: [WIRELESS-LAN] Problems with new Apple Laptops

[Jeffrey Sessler]

Based on the feedback I'm starting to think that the delay in auth is
triggering a login fail on the Cisco side, and after three attempts,
it's excluding the client for 15 mins.
 
One of my students said: "The WPA WiFi just goes away and then I can't
connect to any of the SSIDs (WPA, portal, open) - after 15 mins it
starts working again." I'm also seeing a significant increase in the
excluded clients count.
 
In one residential hall, I found a few AP's not on the same controller,
and moved them all to the same, and it does appear to help, especially
for those between AP's.

like no connection. Worked with our vendor (aruba) and decided to
increase the default idrequest timeout from 5 sec to 30sec. I think
there's something going on when reauthenticating to another AP on the
same ssid. tunnel setup takes a while on the macbook - I think it may be
related to the cert - using the incommon cert - so have server cert
incommon intermediate and addtrust root ca... this is a chunk of data
that gets fragmented... not sure if the mac doesn't like reassembling it
- takes exception to it comming from a new bssid or what. But it does
look like increasing the timeout helps... still a few second without
connectivity - but sure as heck beats the macbook getting stuck in its
authentication step and staying offline until user intervenes.

so still looking into it, but perhaps that info might prove helpful to
others.

macbook is running 10.8.4 - and I was running that prior to changing my
timer settings.

Jason,

Here is more information from an Aruba wireless forum. Seems to be an issue

RE: [WIRELESS-LAN] Problems with new Apple Laptops

[Jason Cook]

Just wondering what the various workarounds people have tried with any success 
at all to this issue? The first patch doesn't appear to have done the job, and 
who knows when the final fix will come. I seem to remember it took Intel the 
best part of a year to resolve 802.11n issues in their 5000 series cards.

We had one user who was getting dropouts every couple of minutes with sometimes 
an almost instant re-connect to minutes. This was after installing the update 
patch. The device has no such issues however on a WPA2/AES-PSK network. This 
has been good to provide a solution there, however PSK's are not overly 
scalable for a campus.

Another user reports that disabling v6 & some sleep settings have helped the 
situation somewhat. I'm hoping to get more information on that sometime today.

I see Travis mentioned below an idrequest time-out increase from 5-30 seconds 
on Aruba.

I'm doing a bit of research now and considering little session of testing later 
in the week so was interested to see what people have tried and how much it's 
helped. Either client or network side.

Re: [WIRELESS-LAN] Problems with new Apple Laptops

I've been getting reports of issues with macbooks on our wpa2-enterprise
ssid - then I finally got one and was able to do some hands on
troubleshooting.

It appeared the mac would decide to roam - but then would fail to auth -
and get stuck in authentication step - wifi menu icon just cycling like no
connection.Worked with our vendor (aruba)  and decided to increase the
default idrequest timeout from 5 sec to 30sec.   I think there's something
going on when reauthenticating to another AP on the same ssid.   tunnel
setup takes a while on the macbook - I think it may be related to the cert
- using the incommon cert - so have server cert incommon intermediate and
addtrust root ca... this is a chunk of data that gets fragmented... not
sure if the mac doesn't like reassembling it - takes exception to it
comming from a new bssid or what.But it does look like increasing the
timeout helps... still a few second without connectivity - but sure as heck

Re: [WIRELESS-LAN] Problems with new Apple Laptops

Hi,

What sort of issues are you seeing?

Could you give us some insight as to what infrastructure you're running, any 
debugs/client traces collected etc?

I have yet to get my hands on the new hardware - but if there's anything we can 
do on the infrastructure to determine if we have any of these clients, that 
might help!

Cheers,
Tristan

Problems with new Apple Laptops

[Charles Rumford]

I've started to see rumors of wireless connection issues with refreshed Apple 
laptops. As most of you know, Apple included AC cards in the MacBooks with this 
refresh.

I was curious if anyone has seen any trouble with the brand new MacBooks. If 
there are problems, I'd like to start squashing them, and potentially putting 
pressure on Apple before the new school year starts.
