Does 7921 support WPA2+AES+PKC?

Does Cisco IP Phone 7921G support WPA2+AES+PKC? I know it supports WPA2+AES, but documentation is not clear if it supports PKC.
Or do I _have to_ use WPA+TKIP+CCKM to support fast secure roaming in CUWN environment?
VoWLAN design guide 4.1 recommends using WPA+TKIP+CCKM. Is that because the phone doesn't support PKC? Is that going to change?

Ok first off the 7921G and 7925G are WPA/WPA2 certified.

http://certifications.wi-fi.org/pdf_certificate.php?cid=WFA5040
7925G
http://certifications.wi-fi.org/pdf_certificate.php?cid=WFA6945
The 7921G is not officially WPA/WPA2 Enterprise certified as we didn't support certicate based authentication at the time (PEAP and EAP-TLS), but do now and the 7925G code is the same as the 7921G, just a slightly different hardware.
As for the 792xG Deployment Guides, I am the one that wrote those docs. :)
There is a statement there in regards to WPA2+CCKM on page 10.
Also WPA2(TKIP) is not a common or recommended configuration. If wanting to use WPA2 key-management it is also advised to use AES.
But the 792xG does support all those methods, but only supports fast roaming (CCKM) with WPA(TKIP) at the moment.

Cisco Centralized Key Management (CCKM)
When using 802.1x type authentication, you should implement CCKM for authentication. 802.1x can introduce delay during
roaming due to its requirement for full re-authentication. CCKM centralizes the key management and reduces the number of
key exchanges. Also, WPA introduces additional transient keys and can lengthen roaming time.
TKIP encryption is recommended when using CCKM for fast roaming as CCKM does not support AES currently.

Does Westell 7500 support WPA2 encryption?

I am using a Verizon-supplied Westell 7500 modem/router. Works fine in wired mode. I have been attempting to enable WPA2 encryption per Verizon Support online instructions http://www22.verizon.com/NROneRetail/NR/rdonlyres/BED1B513-E0CD-4FBE-8545-8EFDF1E34B67/0/ChangeV7500... and the 7500's user guide http://onlinehelp.verizon.net/consumer/bin/pdf/VersaLink7500UserGuide.pdf (p.61-62). Step #9 in the instructions directs me to "Select WPA2 Pre-Authentication". That checkbox is grayed out on my screen, however. I called Verizon Support and was told that the 7500 does not support WPA2 encryption. Huh?? Then what's the purpose of the online instructions and the section in the user guide? Furthermore, they sent me the 7500 after I requested a router that supports WPA2. (My old Westell 327W did not support it.) I thought that it might be possible that my 7500 isn't running the latest firmware http://westell.com/support/versalink/a90-750015-07, but I'm running v. 5.01.00.02, which appears to be the most recent update. Can anyone tell me why that Pre-Authentication checkbox is grayed out? If I want WPA2 encryption, is my alternative to buy another router?
Solved!
Go to Solution.

Pre-Authentication is used for WPA2-Enterprise. Using WPA2 AES with Pre-Shared Key will work fine and is what you are trying to accomplish. So yes, Westell 7500 will do WPA2.

Does Airport Express Support WPA2?

Hi guys! I'm thinking of getting an Airport Express, but I'm wondering, does it support WPA2?

Yes, it supports WPA2.
We've added the Express to an existing Extreme base. Super easy and fast setup.
We use the Express to stream audio only.
To exchange data between computers (and hook up to the internet) we use the Extreme base. So far I cannot see any noticable degration in speed on the Extreme base due to WDS overhead.

Does the 857w support WPA2?

Hi,
Sorry if this is a daft question or in the wrong forum but I am pulling my hair out with this one. According to the spec the 857w router does support WPA2 but I can't for the life of me get it to show up in the configs anywhere. If it does support it does it need a special IOS version or ROM upgrade? If so has anyone any idea which one?
Any help greatly appreciated.
Andy

Hi Andy,
This is not a daft question at all :) It looks like support for WPA2 was added in;
New Software Features in Release 12.4(11)XJ
Advanced Encryption Standard (AES) - CCMP
This feature supports Wi-Fi Protected Access (WPA2) which is the Wi-Fi Alliance specification for interoperable wireless LAN security that supports IEEE 802.11i authentication and AES-CCMP encryption.
From these release notes;

Hope this helps!

TS1398 Does IOS 6.1.1 support WPA2-Enterprise?

Does IOS 6.1.1 on iPhone 4s support WPA2-Enterprise? If I choose other under Wi-Fi I can enter domain credentials and password, but as soon as the phone goes to sleep it no longer can connect to Wireless APs with WPA2-Enterprise authentication.

works fine here. Have you reset the network settings on the phone

Does the mac pro support WPA2 network?

I am trying to figure out if the Macbook Pro supports WPA2 network.

Even the earliest MacBook Pro model (MacBookPro1,1), model# A1150 supported 802.11b/g wireless with WEP, WPA, & WPA2 security.
WPA2 minimum requirements for Macs are:
AirPort Extreme Card
OS X 10.3.3
AirPort Utility 5.0

Palm Pre & WPA2 AES Wireless Networks

I have a palm pre that I'd like to connect to a campus network that uses WPA2 AES encyption. I have the certificate required for this network already installed on the pre. However, when attempting to login to the network, it does not use the certificate and asks for a username/password. Of course, the logins will not work. Any workaround or is this just not supported?
Post relates to: Pre p100eww (Sprint)

Have you tried putting your domain name before the username, i.e. <DOMAIN>\<USERNAME>? e.g.
Username: School\John Doe
Password: **********
If you network is not hidden, you don't even need to specify the security setting. I think it does it automatically when I select a network from the list, at least for me. Good luck!

WPA-TKIP WPA2-AES Connection speed

Hi,
My customer uses controller based wireless network. There is a connection speed problem between two SSID's. First SSID uses WPA(TKIP+AES) and WPA2(TKIP+AES) encryption method and dot1x authentication method. Second SSID uses open authentication (this is a guest SSID)
802.11 a/n/ac is enable on WLC and client can connect with these methods. But clients connect to the first SSID with 802.11 b/g (54 Mbps) and connect to the second SSID with 802.11 a/n/ac. Customer wants to know why our clients connect with low speed to first SSID even if a/n/ac is enable.
Sometimes WPA-TKIP encryption methods can reduce the connection speed. Do you have any idea about that and official document about this problem?
Thanks,
Burhan,

TKIP and AES are two different types of encryption that can be used by a Wi-Fi network. TKIP stands for “Temporal Key Integrity Protocol.” It was a stopgap encryption protocol introduced with WPA to replace the very-insecure WEP encryption at the time. TKIP is actually quite similar to WEP encryption. TKIP is no longer considered secure, and is now deprecated. In other words, you shouldn’t be using it.
AES stands for “Advanced Encryption Standard.” This was a more secure encryption protocol introduced with WPA2, which replaced the interim WPA standard. AES isn’t some creaky standard developed specifically for Wi-Fi networks; it’s a serious worldwide encryption standard that’s even been adopted by the US government. For example, when you encrypt a hard drive with TrueCrypt, it can use AES encryption for that. AES is generally considered quite secure, and the main weaknesses would be brute-force attacks (prevented by using a strong passphrase) and security weaknesses in other aspects of WPA2.
The “PSK” in both names stands for “pre-shared key” — the pre-shared key is generally your encryption passphrase. This distinguishes it from WPA-Enterprise, which uses a RADIUS server to hand out unique keys on larger corporate or government Wi-Fi networks.
In summary, TKIP is an older encryption standard used by the old WPA standard. AES is a newer Wi-Fi encryption solution used by the new-and-secure WPA2 standard. In theory, that’s the end of it. But, depending on your router, just choosing WPA2 may not be good enough.
While WPA2 is supposed to use AES for optimal security, it also has the option to use TKIP for backward compatibility with legacy devices. In such a state, devices that support WPA2 will connect with WPA2 and devices that support WPA will connect with WPA. So “WPA2″ doesn’t always mean WPA2-AES. However, on devices without a visible “TKIP” or “AES” option, WPA2 is generally synonymous with WPA2-AES.
WPA and TKIP compatability options can also slow your Wi-Fi network down. Many modern Wi-Fi routers that support 802.11n and newer, faster standards will slow down to 54mbps if you enable WPA or TKIP in their options. They do this to ensure they’re compatible with these older devices.
In comaprison, even 802.11n supports up to 300mbps — but, generally, only if you’re using WPA2 with AES. Theoretically, 802.11ac offers theoretical maximum speeds of 3.46 Gbps under optimum (read: perfect) conditions.
In other words, WPA and TKIP will slow a modern Wi-Fi network down. It’s not all about security!

WPA2-AES with Certifiacte authentication in WLC

Hello,
I have currently setup with 1200 series AP's as a Stand alone, the authentication is done via radius with Certiface Installed in Client Domain Laptops (WPA2 + AES). The certificate is installed on the domain laptops and when I connect wireless it shows up as WPA2 (Peap). As we migrating to WLAN Controller we unable to authenticate the client with WPA2 AES. In controller if we enable PSK ( Preshared key) its works fine. with 802.1x the authentication not happening and I am getting the error as RADIUS is not responding. But we dont have a control with RADIUS which is in Remote Site. Can some one guide me in RADIUS what needs to check, and with IOS AP its works fine.
Thanks in Advance

You will need to have access to your RADIUS server to set up your controller to support PEAp, its not as simple as upgrading the aps and adding a controller as the controller will need adding as a client to the RADIUS server as a client and depending on your remote access policies adding into the RAS policy. You will need to liaise with the RADIUS support team

WLC-4404. WPA2 - AES (L2) - Microsoft IAS- unable to authenticate

Hi am upgrading from EAP - TLS with WEP to WPA2 - AES with smartcard / machine certificates. AAA server is Microsoft IAS. New SSID and config for WPA2 looks straightforward.
Created new policy for this SSID on IAS, again looks straightforward. Unable to authenticate, debug on WLC looks as though not all server to client transactions are taking place , no EAPOL messages etc.
Any ideas?

This mostly occurs due to incompatibility on the client side. Try these steps in order to fix this issue:
Check if the client is Wi-Fi certified for WPA2 and check the configuration of the client for WPA2.
Check the data sheet in order to see if the client Utility supports WPA2. Install any patch released by the vendor to support WPA2. If you use Windows Utility, make sure that you have installed the WPA2 patch from Microsoft in order to support WPA2.
Upgrade the client's Driver and Firmware.
Turn off Aironet extensions on the WLAN.

EAP-PEAP, CCKM & WPA2 AES

Hi Guys,
Can someone advise on the pros/cons implementing both WPA2 (AES) and CCKM to a single WLAN running 802.1x (EAP-PEAP)?
There appears to multiple conflicting docs about it.
Cheers,
Nick

Hi Nick,
1. WPA2 (AES) and CCKM do NOT work together properly as most of the experts say like this. (but I have this scenario and still i did not herad any issue from employees)
2. Most of the clients don't support WPA2 with CCKM combined because they have overlapping roaming mechanism(this is the reason provides by expert).
3. WPA with cckm works perfectly (as cisco recommanded)

How do I tell what version airport express I have? Airport Utility says this version does not support this base station. What to do, how to update?

I tried to add an older airport express to my network that I had not been using. It shows up in Airport Utility but Airport Utility says that this version of Airport Utility Dies not support this base station. I am running airport utility V6.3.4 on a mac mini running OS X 10.10. Not sure which airport express it is, nor how to check. I assume I need a firmware upgrade on the Airport Express, but not sure how to do this without Airport Utility. I tried to download an older version of Airport Utility, but could not install because it does not support OS X 10.10 Any ideas other than throwing a perfectly good airport express away?

Don't throw the AE away. It is still very useful as I have both the old & new each work well (sometimes the sound keeps dropping out but I think that has to do with the wirless settings!!!)
You need Airport Utility 5.6.1 which works in 10.10 - I managed to download a .dmg from the net but not sure how I could get it to you.
The new utility doesn't support the old AEs unfortunately which I have and Apple have no intention of allowing a utility that will cover all
AEs.
Try and get a version 5.6.1.

Airport utility does not support base station? Help!

I cannot get base station light to turn green. Blinking amber. I upgraded to a new Verizon modem and since then the base station does not work. What can I do?

Make sure the new Verizon Modem is not also a WiFi Router, if it is then that may be your issue. If it is indeed just a Modem then your Ethernet Connection should work and your base station should be working. You said "Airport Utility does not support base station". Don't know what you meant by that. Do you have an Airport Extreme, Airport Express or a Airport TC as a Base Station? If yes, you should be able to set up your Network via Airport Utility. If the Verizon Modem is only a Modem then unplug the power from your Airport Base Station, then unplug the Power from your Verizon Modem for at least 1-minute. Plug the Modem back in and give it a moment or so, then make sure you do have an Ethernet cable going from your Verizon provided Modem to your WAN port on your Airport Base Station. Now power up your Airport Base Station and go to your Airport Utility. Find the Base Station and click on Edit... Make sure your Network Name is correct, your Password is Correct, your Security method is correct (example: WPA2 Personal). If all correct see if your blinking Amber light is now Solid Green.

Does iPhone support WiFi Protected Setup?

I'd like to connect this new iPhone up to my WiFi and retain the same security (WPA2) I'm using with my other clients.

But does it support WPS (WiFi Protected Setup)? And if so, can you tell me how to set up the iphone to join the transaction? Thanks.
