RE: [WIRELESS-LAN] Problems with new Apple Laptops
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. -- Jason Cook Technology Services The University of Adelaide, AUSTRALIA 5005 Ph: +61 8 8313 4800 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Jeffrey Sessler Sent: Wednesday, 25 September 2013 1:41 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Problems with new Apple Laptops Are Cisco customers seeing this as well?

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

Dual Band USB adapters
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
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. Rand Rand P. Hall Director, Network Services askIT!

RE: Dual Band USB adapters
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
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.

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. -- Julian Y.

Re: [WIRELESS-LAN] Problems with new Apple Laptops
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 On Thu, Sep 26, 2013 at 1:43 PM, Julian Y Koh kohs...@northwestern.eduwrote: On Sep 26, 2013, at 15:39 , Travis Schick trsch...@ucdavis.edu wrote: I have found that this delay will go away if the cert used for WPA2 auth is updated to also always trust for SSL. 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. -- Julian Y.
