802.11r Fast Transition and iPhones

Hi everyone
just a clarification about Fast Transition for me:
Following environment: WiSMv2 with 7.4.121, al lot of 1240 APs, over 200x 7921/7925 WLAN Phones and few iPhone 5s / 5c with 7.1 iOS.
The environment work very well for Cisco 792x Phones.
Now the Customer would like to use Jabber on iPhone therefore I create a new SSID for the iPhone and configured it with Fast Transition option.
According to the Enterprise Best Practice for Apple Mobile guide I have to enable the “Over-the-Distribution System” because I user AP 1240
also the old generation.
Further I must enable following over the CLI (options are not available over the GUI):
config wlan assisted-roaming neighbor-list enable
config wlan assisted-roaming dual-list disable
config wlan assisted-roaming prediction enable
Is this the correct approach ?
Regards
Marco

Hi Marco,
you described enabling FT (802.11r) & AP assisted Roaming (802.11k) in the above. Here about some details about how those work.
1. 802.11r FT Association
2. 802.11r Over-the-Air FT
3. 802.11r Over-the-DS FT
4. 802.11k AP Assisted Roaming
I would enable one at a time (802.11r or 802.11k) & see the behavior of these jabber clients when roaming.

802.11r (Fast Transition) - multiple WLANs required for legacy clients?

Hello,
I have a Cisco 5508 WLC with AIR-CAP3502E-E-K9 APs. I want to enable 802.11r (Fast Transition) and understand that some legacy clients may not support 802.11r and therefore if you select, for example, FT 802.1X as an authentication key management, legacy clients may not be able to connect. The Cisco documentation suggests creating a second WLAN with the same SSID, so one WLAN uses FT 802.1X and the other WLAN uses 802.1X.
But when you edit the layer 2 security for a WLAN it is possible to select FT 802.1X and 802.1X. Does this mean there isn't a need for two WLANs with the same SSID? If the client can't authenticate using FT 802.1X will it fall back to 802.1X? Or is the recommendation to always create two WLANs with the same SSID but different authentication key management and the client will connect to which ever one has the "best capabilities"?
For testing I can't find any non-802.11r devices so it's difficult for me to see what would happen if I had one WLAN but with both FT 802.1X and 802.1X selected
Many thanks.

If you remove FT from the WLAN, does the 3G connect ? When FT is enabled, some clients wont connect, thats been my experience.

WLC 5760 and 802.11r/CCKM support

Experts;
I have a couple of 5760 controllers running as MC/MA and I am planning to enable Layer 3 roaming between the two 5760 MC/MA controllers. On a 5508 controller running Air-IOS there is an option, "fast transition", for devices that support 802.11r, my understanding if a device doesn't support 802.11r "fast transition" should not be checked.
I like to know if there is a similar command or option for 802.11r support on a 5760 controller and if the only configuration option to establish mobility between the 5760 controllers is that both controllers need to be in the same mobility group.
Thanks;
Juan

Hi Juan,
my understanding if a device doesn't support 802.11r "fast transition" should not be checked
This is because certain clients that does not support 802.11r (like Mac OSX) won't like when SSID advertising 802.1X & 802.r FT (802.11r mixed mode) on the same SSID. Therefore they will not associate to that SSID. See this post as it listed 802.11r supported & unsupported devices/OS.
https://supportforums.cisco.com/discussion/12314591/8021r-and-fast-roaming
You need to have IOS-XE 3.6 onward to support 802.11r mix mode. (7.6 or 8.0 for AireOS codes)
Regarding config you will find that options (enabling & Over the DS tick box) under SSID configuration (refer link provided by Daniel). If you want to go more into detail how these different options work please read below, I have used 3850 in these post, but config should be same for a 5760.
1. http://mrncciew.com/2014/09/06/cwsp-802-11r-ft-association/
2. http://mrncciew.com/2014/09/08/cwsp-802-11r-over-the-ds-ft/
3. http://mrncciew.com/2014/09/07/cwsp-802-11r-over-the-air-ft/
In your case both 5760 should be in same mobility group in order to MDID to be same which is required for 802.11r fast roaming.

Wireless 802.11r and .k on WLC

Hello all,
I've seen that in 7.4 and later Release on the WLC5508 you can configure 802.11r and 11k support using Fast Transaction so that iOS7 won't experience connection loss during Roaming...my question is on the same WLAN can I configure 802.1X and FT-802.1X Authentication so that I'll be able to have on the same SSID non802.11r and 802.11r capable client? Or this setup will create association problem ?

Maybe this can help explain it also:
http://www.cisco.com/en/US/docs/wireless/controller/7.3/configuration/guide/b_wlc-cg_chapter_0111.html#d155467e2632a1635
Legacy clients cannot associate with a WLAN that has 802.11r enabled if the driver of the supplicant that is responsible for parsing the Robust Security Network Information Exchange (RSN IE) is old and not aware of the additional AKM suites in the IE. Due to this limitation, clients cannot send association requests to WLANs. These clients, however, can still associate with non-802.11r WLANs. Clients that are 802.11r capable can associate as 802.11i clients on WLANs that have both 802.11i and 802.11r Authentication Key Management Suites enabled. The workaround is to enable or upgrade the driver of the legacy clients to work with the new 802.11r AKMs, after which the legacy clients can successfully associate with 802.11r enabled WLANs. Another workaround is to have two SSIDs with the same name but with different security settings (FT and non-FT).

Why is my mac internet slow and iphone fast, when both are running through the same router?

Hi
I have tried all sorts to fix this. The obvious resetting, rebooting etc of the router. I have spoken to my provider and stuff.
My internet on my iMac is terrible. I turn off wifi and back on and it works for about 20 seconds then stops. Very intermittent and hardly ever fast.
My iPhone however loads pages and apps that use the internet instantly. I am sitting at my computer so i cannot see why there would be a difference!
Its making my head hurt

Use the 5GHz Band Compared with the 2.4GHz band, the 5GHz band is practically empty. The newest AirPort Extreme Base Station is one of the few Wi-Fi base stations designed for home use that work in that 5GHz band. All of Apple’s Core 2 Duo laptops and iMacs (except the discontinued 17-inch 1.87GHz model) can also use the 5GHz band; with the build-to-order wireless option, so can the Mac Pro.
To switch to the 5GHz band, launch AirPort Utility, select your base station, and switch to Manual Setup. Click on the AirPort button and select the Wireless tab. Select 802.11n Only (5 GHz) from the Radio Mode pop-up menu. Click on the Wireless Options button and select Use Wide Channels. Click on Update to restart the base station.
Currently, no Mac-compatible adapters enable you to use the 5GHz band in older Macs or with older versions of OS X.

Airpcap and WireShark support for 802.11k, 802.11r, 802.11u?

Folks,
I have a need to troubleshoot/test 802.11k, 802.11u, and 802.11r messaging.
Does anyone know if AirPcap Nx + Wireshark will capture and properly decode these 802.11 amendments:
802.11k
802.11r
802.11u
I have looked in Wireshark forums and seen references to all of the above amendments but I can't find anything conclusive to indicate the level of support for these headers/fields/messages.
Thanks for any insight.
Joey

George,
I don't know yet. However, to begin testing devices I'll need a tool that can decode the protocols so I can see who supports what.
Based on my research for evidence sake,
Wireshark 1.7.0 dev branch appears to:
Support 802.11u fully
Support 802.11r fully
Support 802.11k partially
The 802.11k information elements I can't find or are not supported for 802.11k are:
7.3.2.42 Measurement Pilot Transmission Information
7.3.2.43 BSS Available Admission Capacity
7.3.2.44 BSS AC Access Delay supported
7.3.2.45 RRM Enabled Capabilities
7.3.2.46 Multiple BSSID

IPad 2 AND iphone 4 battery draining FAST since IOS 6 update!

I have done EVERYTHING I can think of and that has been suggested all over the World Wide Web to improve the battery life of both my iPad 2 and iPhone 4 since the IOS 6 software update. Nothing works!!!! I am leaving town in a week, and I would like my phone to be working the way it did before.
Still taking suggestions to fix this.
APPLE please do something. I am losing faith, and I am also losing my desire to buy the new iPhone 5!
APPLE PLEASE HELP!
Thanks in advance!

Have you tried closing all apps? Double tab the Home button, then tap down on an icon and hold for about 3 seconds, until the icons are moving slightly. Click on the above every App.

Ipad and Iphones (w/ iOS 6) 802.11n AP's with TSPEC video enable

Does not work with Enterprise 11n AP's wth TSPEC (admission control) enabled.
If TSPEC is disabled, it connects and work OK. Any experiences or thoughts??.

We have Cisco branded 1142's and have noticed the same thing. It seems to be the combination. If we disable N radio....things work. Or, disable admission control and it will start working. iphone 4 on ios6 and iphone 5 on ios6 behave the same way. iphone 4 on ios 5.1.1 works.

I updated both iPad and iPhone to iOS 7.06. Battery lif goes extremely fast, maybe a tenth of what it was.

I updated to the latest version of the iOS. My battery life on both iPad and iPhone have dropped to nothing. My phone goes dead by noon. I have turned off every "push" locator, everything I can think off. Is anyone else having this trouble?

On my iPad 3, I noticed with the update to iOS 7.0.6 that it turned on features by default that I had previously turned off, such as Bluetooth. You might want to check to see if active features are now turned on that you previously turned off. Some of them, like Bluetooth, will cause an additional drain on the battery.

Voice over WLAN - Cisco 2504 and iPhones/Androids

All:
I'm working on a solution for someone who already has a Cisco WLC 2504 running 7.6.100 and 2602i APs. They are running iPhones with a SIP application instead of purchasing Cisco 7925G phones. They are having issues when roaming to different APs.
Site survey is good. I also used a laptop with Net Surveyor on it - signal looks good. SNR is good. They used to have coverage issues as well but I got that taken care of for them. Only issue now is roaming.
WLAN SSID:
-Qos: Platinum
-FT-PSK and PSK enabled
802.11a/n/ac Radio:
-Client Roaming: -67dBm for RSSI threshold and -62dBm for scanning threshold.
-Disabled 6mbps and 9mbps and 12 mbps is set to mandatory. All others are supported
802.11b/g/n Radio:
-Client Roaming: -67dBm for RSSI threshold and -62dBm for scanning threshold.
-Disabled 1mbps - 12mbps. 18mbps set to mandatory. All others are supported
Switch to which WLC is connected:
-switch ports used to connect to the controller are set to trust CoS and ports to APs and uplinks are set to trust DSCP.
With these setting changes - I believe most everything else is default. I am confused about the following:
-Best practice link - http://www.cisco.com/c/en/us/td/docs/wireless/technology/vowlan/troubleshooting/vowlan_troubleshoot/2_Gen_Troubleshooting_Guidelines.html
Says to configure voice WLAN to use 802.11a. Issues with that: Some Android's could not connect AND the big one - I am not able to set Qos to use 802.1p for the SIP WLAN. It tells me to disable 802.11a and 802.11b. If I go into each radio on 'Network' tab and disable these - NOTHING can connect to any SSID. So unless I've misunderstood something - this is a contradiction in the best-practice link I posted above.
another question: If I enable FT-PSK and PSK - for devices that support FT-PSK (which i'm under the impression is 802.11r) will these devices use that and for devices that don't they'll use 'regular' PSK? How do I know if my client is connecting using PSK or FT-PSK as both are enabled on the same WLAN.
Again - only issue is roaming. I second or two of 'choppy' voice then everything is back to normal working as expected. Any ideas as to what else I can enable to get these iPhones to roam better - if this is even possible. Can iPhones roam using a SIP app with zero voice interruption? This is the equipment that they got and can't get anything else so I got to make the best of this. Perhaps I've already done that? Any ideas/suggestions are very much appreciated.

Hi
Before any other think I would like you to upgrade your WLC image to 7.6.130.0 & FUS to 1.9.0.0. FUS upgrade will require 30-40min downtime to your wireless.

It tells me to disable 802.11a and 802.11b. If I go into each radio on 'Network' tab and disable these - NOTHING can connect to any SSID. So unless I've misunderstood something - this is a contradiction in the best-practice link I posted above,
This simply says, you have to disable radio band before changing QoS profile values. Once you change those value you can re-enable the radio band. :)
If I enable FT-PSK and PSK - for devices that support FT-PSK (which i'm under the impression is 802.11r) will these devices use that and for devices that don't they'll use 'regular' PSK? How do I know if my client is connecting using PSK or FT-PSK as both are enabled on the same WLAN.
Read these 802.11r post & you will understand how 802.11r works. There are certain client devices does not like PSK & FT-PSK capability advertise on the same SSID & may have connectivity issues. But most of the clients like iPhone, iPads,etc will connect without any problems.

"show client detail <mac_address>" should indicate if client connected over FT-PSK or PSK.

802.11r on iOS6

Just figured out that iPhone 5, iPhone 4S and the new iPad(not iPad 2) running iOS6 can support 802.11r roaming with Cisco WLC 7.3.
Find more detail in my blog. Hope this helps.

New HH3 - Issues with Kodak Printer and iPhone 3GS

Hello,
Here is the background:
Previously had a D-Link DSL-G624M router and everything connected wirelessly. This included 2 laptops, Kodak ESP 5250 Printer and iPhone 3GS. Router broadcasting on channel 6 (locked).
Since upgrading to Infinity replaced the D-Link with a HH3. Laptops connect fine but have issues with other wireless devices.
iPhone: Seems to lose internet (not necessarily wireless connection though) intermittently. The phone remains connected to the HH3 and can be seen in the DHCP table and Home Network screens. The iPhone also reports that it is connected to the HH3. However, when attempting to access the internet using either Safari or apps it doesn't work. This can be fixed by forgetting the network and re-joining or turning Airplane Mode on and then off.
Kodak ESP5250 Printer: This connects fine to the HH3 and remains in the DHCP table and Home Network with the correct IP Address. Laptop A is able to connect and print successfully. However, after putting the laptop into sleep mode and re-waking it it is unable to Print. The Printer is still connected to the HH3 and laptop claims it is 'Ready' but unable to print. The only way i have found to fix this is to re-install the entire Printer software!! However, Laptop B does not have this problem and can be put into Sleep mode, Hibernate or restart and the printer remain connected. I do not think it is a firewall issue as able to connect until re-waking from sleep.
You're probably thinking the same as me that this sounds like hardware issues and not the HH3. Maybe coincidence that it started happening after changing to HH3. Maybe something wrong with the iPhone or Laptop A and/or Printer?!? Tried setting a manual channel on the HH3 as suggested by other posts but this had no effect. (Used inSSIDer to determine best channel). Also increased the IP Address lease time from 1 Day to 21 Days - but again no difference.
Current situation: Connected the D-Link router to the HH3 using Ethernet cable. Disabled DHCP and DNS on the D-Link router and kept SSID different. Now connected all devices to the D-Link router and nothing to the HH3 and everything is working as it did previously. The iPhone remains stable and the Kodak printer remains connected to both Laptops after re-waking from Sleep Mode.
I haven't yet contacted BT but i'm leaning towards it being a dodgy HH3. Anyone have any suggestions??
Thanks,
Martyn...

For starters, there's nothing wrong with your Iphone or Kodak prn. The issue is the HH3
I had a very similar issue connecting iMac, iPad, Macbook Pro, iPhone, Thinkpad and Canon prn via wireless to the HH3... Lots of disconnections, devices that couldn't log in, very low wireless speeds, printer not recognized, etc,etc
I went mad, pretty much did the same things as you did: inSSIDer, changing channels, re-installing whole softw drv !, reorientating HH3 position, manually assigning IPs and channels... nothing would seem to work!
Then I connected a Netgear router to HH3 via ethernet cable -like you did- and suddenly everything seemed to go back to normal. Here's what I found out after much head knocking:
1) The issue is the HH3, not that it's faulty but simply put it can't deal with lots of wireless traffic. The minute you connect several devices it gets clogged up
2) HH3 seem not to recognize WiFI printers that have a 'static' IP (not sure why)... this was a nightmare
3) if you have many devices connected, HH3 doesn't seem to 'like' Apple devices or wifi Airport powered (not sure why). After sleep mode these device can't pick up IP over the air, and you need to manually renew DHCP leases. There are several reports about this in Apple forums.
So here's what I did:
1) I ditched the HH3
2) I connected the Openreach router to a dual-band Netgear wndr3400 **cable** router (PPPoE connection)
3) I re-installed the prn drv in USB mode and then added wifi printer in wifi mode while usb connected
4) I created two-split WIFI networks; one in the channel 6/2.4Ghz frequency and another in the channels 44-48/5Ghz freq to which I assigned most devices (It seems BT Infinity wifi works best in 5Ghz channels)
Results: all devices recognised & connected via WiFI, no disconnections, steady WIFI speed almost as fast as ethernet cable, wifi prn prints fine from all devices... No more WIFI connnectivity issues.
I hope this helps, good luck
(note: my current issue is that my profile dropped from 34/8 to 21/2 during testing phase)

HT4759 I want to use icloud mail on both iPhone 4s AND my pc. icloud mail on PC is mega glitchy and frustrating because my PC is ancient, I run XP, & these DO NOT MEET req's for iCloud. Is there a email platform that will run well on both XP and iPhone?

I NEED to use icloud mail on both iPhone 4s AND my PC. I need to use both.
Trying to use icloud mail on PC is mega glitchy (STOP SCRIPT WARNINGS EVERY FEW MINUTES) and frustrating because:
1. my PC is ancient (but nicely refurbished/fast)
2. I run XP (with both Firefox and Chrome- newest versions)
3. thusly, I DO NOT MEET SYSTEM REQUIREMENTS for iCloud.
In my passed attempts I found that
1. Yahoo doesn't work well on iPhone
2. Gmail doesnt work well on iPhone.
I must be missing something... an app or... maybe a donated/ NEW FREE MAC! (That would be sweet! Ha.)
Is there an email platform that will run well on both XP and iPhone?
or... Please say it isn't true: I would love a Mac tablet or desktop. We have no money for a mac. SOL? Is this iCloud apple tech only for wealthy middle class and above who can afford to have the newest and best of everything?

@Naiks, having suffered through unsuccessful synching attempts for Calendar and Contacts myself, l would suggest you try the following:
UNINSTALL iCloud control panel from your PC. Seems silly, but do it.
Go into Outlook, and look at the very top menu. Click FILE, then ACCOUNT SETTINGS, then click the popup box.
You will see a list of all your email accounts. Make sure that ONE of them has a checkmark against it. If not, select the account your want as your default, and click "set as default.
Exit out of Outlook and reboot your machine.
Now reinstall iCloud, check CALENDAR and CONTACTS, and do as instructed when prompted.
Reboot for good luck and now launch OUTLOOK. All that remains is to locate your iCloud Contacts and Calendar files, and make them your default.
IMPORTANT: Don't panic if you can't find your contacts -- they're there. Click CONTACTS and you'll see you have several available contact files. Locate the one label "iCloud" in grey type. Right-click on it, select PROPERTIES, then click the Outlook Address Book tab. Check the box that says something like "Make this my default Outlook Address Book." Keep clicking "apply" and "okay" until you've exited out of the dialog box maze.
You may have to do something similar with your Calendar files. I dd not, but if you need to, do it.
Everything should now sync pretty seamlessly.
I didn't have the exact same problem as you, but my dilemma was close enough. Good luck!

Call Forwarding Breaks with iOS 8.3 Update on iPhone 6 and iPhone 6 Plus with AT&T

Ever since the iOS 8.3 Update, call forwarding is no longer working on my iPhone 6 Plus. I have spent dozens of hours troubleshooting with both AT&T Advanced Business Technical Support as well as many hours with top technicians from Apple at my local Genius Bars.
This is a critical bug for me as I used to use the call forwarding option multiple times a day, EVERY DAY, because when I am in certain business locations my mobile phone gets no reception and calls go right to voice mail. I need to have them forwarded to the land line I'm located at.
APPLE, PLEASE HELP!!!
I've done extensive testing, and this seems definitely to be related to Apple iOS 8.3, and it seems to be specific to the iPhone 6 and iPhone 6 Plus ONLY.
To illustrate the EXACT problem:
A: Settings -> Phone -> Call Forwarding
B. Call Forwarding - Turn on
C. Enter Number and return to previous screen by touching the blue "Call Forwarding" to return to previous screen.
D. Call forwarding button is "green" for a split second, then returns to previous OFF state and no forwarding number is displayed. DOES NOT WORK.
NOT AN AT&T PROBLEM. IF SOMEONE IS EXPERIENCING THIS WITH OTHER CARRIERS PLEASE COMMENT HERE.
Further validation this is isolated to iOS 8.3 on the iPhone 6 and 6 Plus ONLY and not the sim card from AT&T...
Here are the latest steps I did with my AT&T sim card and my wife AT&T sim card (she has an iPhone 5s):
1. Removed my sim and put it in the 5s. The phone said that a "carrier update" was required and I selected "NO" to that prompt. Call forwarding functionality worked as expected on the 5s running iOS 8.3
2. I removed the sim from the 5s and re-inserted it. This time I selected "YES" to do the carrier update to eliminate that as a variable, and the call forwarding functionality still worked as expected.
3. I then placed my wifes sim in my 6 Plus. Call forwarding functionality does NOT work on the 6 Plus (was not prompted for carrier update). Also, keep in mind this is my second phone (Apple provided me with a new iPhone 6 Plus when they couldn't resolve the problem at the Genius Bar after hours of troubleshooting).
Note: I did one additional test which as interesting: I put my sim in the 5s and turned call forwarding "on". Then, I put the sim back into my 6 Plus. The calls were still being forwarded to the number I put in while it was in the 5s, but the call forwarding interface in the 6 Plus showed that it was NOT forwarding calls. I could not turn OFF the call forwarding from the 6 Plus and had to put the sim back into the 5s in order to turn off the call forwarding.
If anyone has an update on this, or any other suggestions please advise! This is a critical issue for me as when I travel and when I am in poor areas of reception I need to forward calls. This is a featured I was using multiple times a day, EVERY DAY.
APPLE????????? HELP!!!!!!

Yes, I am dealing with this right now on at&t with a 6 plus. I've been down the same road as you. I got it to work with a windows phone yesterday but not my 6 plus when I switched back to the iPhone. My wifes 6 works fine. I believe it is an at&t issue and not an 8.3 issue. After dealing through several levels of support at at&t, they are telling me it has to do with their transition to hd voice. Some people are having this issue because they are updating their system and some peoples phone profile, on phones that have hd voice capabilities, are not getting added to their line and call forwarding will not work without it. I have a trouble ticket open to their engineering dept and they promise it will work for me on or before the 24th of april. Engineering has to build my phones profile so call forwarding will work with my iPhone.
This is frustrating because like you, I need to forward my calls because I have no signal in my office and need to forward to another phone so I can get my calls. If at&t would quit dragging their feet and enable wifi calling, this wouldn't be an issue for me. I would suggest you put more pressure on at&t and escalate this until it gets resolved. Or put your sim in a phone that does not have hd voice capability and see if it works then.
Good luck. I'm keeping my fingers crossed this will be fixed for me on or before the 24th. We'll see.
EDIT: I see you did put it in another phone and it worked. That backs up that the issue is at&t and their hd voice upgrades. They had no explanation as to why some work and some don't, but have them make sure a profile for your phone is on the line. If not, they'll need to build one for the phone so that it''l work. At least that's the story for now. Like I said, I'll know more in a day or two.
