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

2013-09-26 Thread Jason Cook
Thanks Mike,
A bit of playing has shown why we haven’t had too many complaints, but when 
there is one we know why. The one user that had issues every couple of minutes 
was in between 2 AP’s, but each AP had a  different controller backend so 
re-auth. Migrated so that both AP’s were on the same  controller and issue went 
way. Well it’s still there, however the trigger event for a re-auth is much 
less so the impact is minimal. Typically we keep all AP’s in a building on the 
same controller.
Jeff,
We have Cisco so yes, but we don’t have a guest portal. If a client can’t 
connect it  normally falls back to the next available in the wlan list.

Another user reports that disabling v6  some sleep settings have helped the

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

I’m doing a bit of research now and considering little session of testing later

Dual Band USB adapters

2013-09-26 Thread Paul Walker
Has anyone suggested to students that only have single-band wireless adapters 
to obtain a dual-band USB adapter for better performance (by driving them to 
the 5ghz band)?  If so, have you seen adapters that you would not recommend in 
an enterprise environment?  We have a Cisco wireless infrastructure and have 
been testing the Cisco/Linksys AE3000 and newer AE6000 USB adapters.  No real 
feedback from students yet, but am looking for other viable options to 
recommend if they exist.

Background:
We have one residence hall that is half student housing and half HUD senior 
housing.  We own the building, but can't take full occupancy until some date in 
the future (2018 maybe).  Due to leasing agreements and such, we don't have 
students all on the same floors (students and seniors are intermixed on every 
floor).  This building is all wireless and has about 7 APs per floor.  We 
believe that due to the AP density and the possibility that there is personal 
wireless (in the senior housing apartments)  in close proximity to our 
infrastructure, we could be dealing with a great deal of interference in the 
2.4 Ghz band.  Roughly 53% of all wireless devices on campus are running 
802.11n on 2.4 Ghz.  Almost every student that has called to complain about a 
poor wireless experience in this hall is using the 2.4 Ghz band.  Hence the 
desire to provide options to our students with single-band adapters to purchase 
something that is a dual band.

Re: [WIRELESS-LAN] Dual Band USB adapters

2013-09-26 Thread Hall, Rand
I suggested a USB adapter for the first time yesterday! An expensive
alternative to asking your neighbor to turn off their bleating HP
printer...but that was the option chosen.

You might want to survey the area to verify your hypothesis. My guess would
be that you have more 18 year old printers and routers than 70 year old
routers. If you do end up with a lot of hip grannies I might consider
carving out a Free Senior Wireless--complements of Moody SSID and just
give them free internet access to rid yourself of the problem. If you hunt
gramps' routers down you can mark them as known rogues and let your auto-RF
channel assignment do it's job and plan around them.

RE: Dual Band USB adapters

2013-09-26 Thread Anthony Laffan
At UMass Amherst we use USB Dual band Adapters to help diagnose wireless issues 
for students on campus. If they only have a single band adapter we lend them a 
Linksys AE2500 dual band and see if that helps. I'm not sure on the actual 
numbers, but switching from a single band to a dual band adapter does solve a 
large number of problems for students.

We have also used Linksys WUSB600N adapters before and those also worked well. 
As long as the adapter is wi-fi certified and dual band it seems to work 
reasonably well here.

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

2013-09-26 Thread 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.

 Here is more information from an Aruba wireless forum. Seems to be an
 issue with Macs and certs.

 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.

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.

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
