IPhone 802.1x WiFi authentication problem

my WiFi access works fine at home and almost all WiFi areas. but i go to school where wireless access is authenticated with a login and password. it works fine on my macbook. since the iPhone has OSX, i thought the school's WiFi would work on my iPhone, but it doesnt. i can see the Network on my iPhone and it has a check mark. but i cant connect to it because i am not authenticated (i think). anyone know how to do this?

On the iPhone when you try to connect to 802.1x it may ask for a password, no username, but this won't allow you access to the network. No support for it yet.
Some also allow IPSec and/or PPTP for WiFi you might check with your help desk people. In this case you might see the network but it would not allow you access to anything. You would need to setup VPN settings in Settings > General > Network > VPN > Settings to make a VPN connection. You have to go back to this location to enter your password because it does not save it. Also if you try to use Settings > VPN to connect, you get a number pad not a keyboard to enter your password. This works fine for Apple employes but almost no one else in the world.

WiFi Authentication problem

I have an iMac, and iPad, a Blackberry (forgive me) and Airport for my WiFi all of my pieces are working fine with my WiFi. I had guests over the other day and we could not allow my guests iPads or iPhone to sign onto my network. I bought my dad a generic tablet to use for solving cross words, etc., and I cannot sign into my own network. No opportunity exists to put in a password because it just reads "Authentication Problem".
No opportunity exists, therefore, to enter the password. Signal strength is excellent, Securty is WPA2 PSK, I touch connect and it says Saved Secured with WPA2 and then goes back to "Authentication Problem."
I've unplugged (and plugged back in) both the Airport / router and Internet Service provider's modem. I've rebooted my iMac and the new generic pad 3 times each.
I had 2 networks one for me and one for guests, can't get into either, identical problem. I can see all of the neighbour's networks and they're all locked and say secured with (various WPA/WPA2, etc., just mine says Authentication Problem. I plugged the tablet into my iMac and it's functioning well.
I now deleted the guest network and can't open a new network.
I've triple checked my passwords, hand written and in the Key Chain.
I've checked my Apple ID (I'm able to get into this forum).
Both my iPad (purchased May 2013) and BlackBerry (received free July 2013) signed in without any problems.
I cannot see why I can't get into my network ~ any ideas?

Wifi Authentication Problem in Lenovo K900

Hi,
I am able to connect to wifi at home network. And when I try it at office it is showing Authentication problem and "Not in Range". The password and everything is correct. All my colleagues are able to connect with the same password. I searched online for the solution and there are many other lenovo tab and phone users facing the same problem and I am unable to find the solution. Can anyone resolve this issue and give appropriate answer for this.

This is the first time I'm hearing this issue, I'm also an K900 user but this never happmed to me or my other friends.
Are you sure that's the right password, maybe its case sensitive, because this bug is not present in K900.

ESW 520 802.1x MAB authentication problem

Hello,
I am having problem with 802.1x MAB authentication on ESW 520 switch, the authentication server is ACS 5.3.
The Authentication method on ESW is 802.1x & MAC, and Host Authentication mode is Multi Session. When i plug ip phone it never authenticate the phone, and on ACS I get following error message:
Radius authentication failed for USER: aa1effbb8fd4 MAC: aa-1E-FF-bb-8F-D4 AUTHTYPE: Radius authentication failed
RADIUS Status:Authentication failed : 11509 Access Service does not allow any EAP protocols
15004 Matched rule
15012 Selected Access Service - MAB
11507 Extracted EAP-Response/Identity
11509 Access Service does not allow any EAP protocols
11504 Prepared EAP-Failure
11003 Returned RADIUS Access-Reject
For that Access Service I have configured only Host Lookup.
The same ACS configuration is working perfectly on Catalyst 3560G switche.
It seems that ESW switch is not telling ACS that authentication is going to be by MAC address.
Do you have any idea what can be the problem.

Are you hitting the same selection rule? Also is "mab eap" configured globally on the switch, or on the port itself?
Also can you post the port configuration and the show ver of the ESW?
Thanks,
Tarik Admani

How do I correct LG Lucid wifi authentication problem

LG Lucid was working fine until few days ago when it stopped connecting to all available wifi networks. It still ID's them, goes thru authentication process, & then provides error message "authentication problem". I think there was aa phone update about the same time things stopped working. Help please.

I know this is an old thread, and would hope you've gotten connected to your WiFi by now, but you may want to check your router settings. If you have some sort of device filtering set up, your for may not be recognizing your phone since the update.

Hi,I am a new member and have just upgraded to android 5. Seems a big mistake as cannot connect to internet (no trouble with android 4) Says authentication problem. Have tried cancelling and re-entering password, turning router on and off and factory reset. Nothing. If Lenovo come up with a repair how will I be able to get it into the tablet when I have no internet connection.At the moment I have a tablet that is about as usefull as a roof tile. HELP

You have been looking everywhere, except this forum. This issue was already addressed in this thread: https://forums.lenovo.com/t5/Android-Yoga-Series-Tablets/Wifi-Won-t-Connect-quot-Authentification-Problem-quot-Yoga/td-p/2105009 Are you using a WEP key encryption?

Ipad 2 802.1X PEAP Authentication problem (With profile from IPCU)

Hi!
I'm in the processes of setting up a new wireless network for a costumer.
A little info about the hardware:
Cisco WLC 5508
Cisco AP 2602i
Cisco ISE - radius server
ipads gen 4 (iOS 6)
EAP-TLS (windows machines) and PEAP (Other stuff, ipads, andriod etc) as authentications methods
The radius server is using a server certificate from thier own PKI infrastructure therefor i need to push the root certificate of their CA to the clients in order to verify the authentication server. For this I use the iphone/ipad configuration utility.
I use the Use Per-connection password option
User that are allowed to connect are placed in a specific group in there AD.
The problem that I have is:
When a user thats not allowed to connect tries to authenticate to the network the ipad says stop and thats the way it supposed to be.
BUT after someone has faild to authenticate to the network and somebody else tries to connect the ipad only ask for a password and not a username.
I cant seem to get rid of this popup and therefor the ipad cant connect.
If I don't use the profile I can forget about the network and after that i can connect with a different user.
But then i can't verify the server-certificate and use the option per-connection password!
Please help!
Has someone else seen this type of bug.

Hi, I am new with 802.1x, and was hoping that someone would help with these queries:
1. How is a certificate requested without being allowed on a network that is not authenticated with 802.1x. I had to first connect to an active network, retrieve a certificate with the proper username and password, and then physically connect to the port on the 2950 switch which was enabled to do 802.1x
2. My config is as below:
aaa new-model
aaa authentication dot1x default group radius
aaa authenication login default group radius
dot1x system-auth-control
interface f0/1
switchport mode access
dot1x port-control auto
end
I able to login using the radius server, so radius is working (on ports other than f1/0). However when connecting to f1/0, the port on the 2950 remains blocked.
3. The certificate is issued by the ca server, is viewable via Internet explorer,and is issued to the correct username which is on the active directory.
I even tried using local authenication with 802.1x, this did not work
4. If I have a certificate, will this automatically give me access to the 802.1x port?
5. I have windows 2000, and authenication is set to 'Smart Card or other certificate.
Am I missing anything?
Any advise will be greatly appreciated

Why my iPhone 5s's wifi have problem with wifi on iOS 8.0.2?

MMy iPhone 5s and also my iPhone 6 plus and iPad 3, all have the latest update(8.0.2) but all of me have problem with wifi and gilt hung all the time! Wifi most of the time is not working and we have to use laptop or using phone data, obviously I don't want to use my data in home so , I want this problem solve as soon as possible. My iPad is glitching all the time, my iPhone's most the time.
aand please don't tell me it's my wifi modem because I know it's not, I have been tested my modem with all other devices!

Ok. Have you tried restarting your phone? Hold sleep wake button until slide to power off appears - slide to power off. Turn it back on and retest.
-Next is Settings, general, reset, reset network settings - retest.
-Next is back up phone to iTunes, and restore to factory settings - set up as new, retest.
If you have had your phone for less than 90 days, you get 90 days of complementary voice support at applecare, so you should definitely use that while you have it.

802.1x re authentication problem

Hello,
I have problem with 802.1x authentication on switch ports which are configured in "Multi Session" mode. In Single host mode and Multiple Host mode it works just fine.
The problem is following, when PC is first connected on switch port it authenticates successfully. After about 1-2 minutes windows 7 NIC notifies that its going to authenticate again, and after couple of minutes NIC status is changed to “Authentication Failed”. On ACS I only see first authentication request which is successful. If I unplug PC from port and plug it again. It authenticates successfully and then starts again with same problems.
I was doing packet sniffing on PC, and it seems that after pc first authentication completes successful, switch starting to sent EAP Identity/Request packets to host, for that host is sending EAP Identity/Response to switch, but switch don’t continues authentication process and starts again with new EAP Identity/Request packets.
On Windows 7 host Event viewer I see following log messages:
                Reason: 0x70004
                Reason Text: The network stopped answering authentication requests
                Error Code: 0x0
The ACS version is 5.3. Authentication method is PEAP. Supplicant OS is Windows 7 I also trued with Windows XP, with same result. The Authentication switch is ESW 520 with latest firmware. I also trued with 2960/3560 switches and it works perfectly. On ESW 520 switch if port mode is other than “Multi Session" if works without any issue.
Do you have any Idea how can i fix this ?

Hi ngtransge,
Thanks for rating the replies. You need to select "User Authentication". I am pasting some screenshots which might help you out.

802.1x RADIUS authentication problem with Cat 2950 to CiscoSecure ACS 3.3

I wondered if anyone can help or shed any light on the following problem.
I am getting an authentication error when doing a RADIUS authentication to CiscoSecure ACS 3.3 running on a Windows 2003 server, the authentication request is coming from a Catalyst 2950 switch which is doing 802.1x for Windows XP clients. This problem only happens when the XP client connects to 2950 switches, Cat 3550s and 3560s work fine.
The Cat2950 is running 12.1.20 (EA1) which is more or less the latest IOS.
The error I get from ACS 3.3 is "Invalid message authenticator in EAP request" when the 2950 tries to authenticate an XP client for 802.1x to the ACS server using RADIUS.
Doing a RADIUS and 802.1x debug on the 2950 I see a message about 'Unknown EAP type', I am using PEAP on the XP client doing EAP-MS-CHAPv2 authentication, the same XP client authenticates fine with 3550 and 3560 switches problem only affects 2950s. Can anyone confirm the 2950 supports EAP-MS-CHAPv2?
I have checked and re-checked the shared secret and it definitely matches on 2950 and ACS.
One thing I noticed in the RADIUS debug is the 2950 sends 18 bytes for attribute 79 when the RFC defines attribute 79 should be 3 bytes or less, I don't know if this is related to the problem or is correct behaviour.

Hi, I am new with 802.1x, and was hoping that someone would help with these queries:
1. How is a certificate requested without being allowed on a network that is not authenticated with 802.1x.

aaa authenication login default group radius
dot1x system-auth-control
interface f0/1
switchport mode access
dot1x port-control auto
end
I able to login using the radius server, so radius is working (on ports other than f1/0). However when connecting to f1/0, the port on the 2950 remains blocked.
3. The certificate is issued by the ca server, is viewable via Internet explorer,and is issued to the correct username which is on the active directory.
I even tried using local authenication with 802.1x, this did not work
4. If I have a certificate, will this automatically give me access to the 802.1x port?

ESW 520 802.1x re authentication problem

Hello
I have problem with ESW 520, on 802.1x authentication. The problem is when host authenticates successfully it works about couple of minutes, after it truest too authenticate again but it lags. On network interface it shows notification that if Failed authentication. On ACS I see only one authentication attempt which is successful. This problem is happening on Win7 and Win XP. If I unplug and plug cable it authenticates successfully, but then about couple of minutes it again lags. Switch sees port as authenticated. On Win7 event viewer I have following error:
                Reason: 0x70004
                Reason Text: The network stopped answering authentication requests
                Error Code: 0x0
If I connect same hosts on Catalyst 2960 switch, they work successfully.

Hi ngtransge
There are tree possible explanations about why the authentications fails.
A)the network interface is shut down after failed computer authentication. You can see this on the switch as line protocol down for that port.
To verify the client has a domain certificate:
1. Click Start and click Run.
2. Type mmc, and then press ENTER.
3. On the File menu, click Add/Remove Snap-in.
4. Click Certificates, click Add, select Computer account, and then click Next.
5. Verify that Local computer: (the computer this console is running on) is selected, click Finish, and then click OK.
6. In the console tree, double-click Certificates (Local Computer), double-click Personal, and then click Certificates.
On a domain joined client, you should see a certificate here with Intended Purposes of Client Authentication. Make sure this certificate is not expired. If it is expired, you will need to regain connection to your CA to request a new one.
B) You should check your switch's configuration, perhaps a port or some ports could be blocked by an access-list and interrupt the re authentication.
C) If this two solutions don't work, you have to try to change the authentication method (PEAP-MSCHAPv2 or PEAP-EAP-TLS)

Macs joined to AD Domain, and 802.1x/mab authentication problems

Hello, I've got a situation where i have a small handful of Mac Pro's running OS 10.6 that are having some trouble with wired 802.1x/MAB (Mac Autehntication Bypass) on our cisco switches. We have our macs setup so that they autenticate to our windows domain for user login, plus, we have 802.1x authenciation (for our windows clients) and MAB bypass for our macs, printers, and assorted other equipment. Problem seems to be, the Mac boots up before the switch goes into MAB bypass and wont let the user login to the network. Has anyone ran across this problem before and found a solution?

hello,
in my organization we have multiple 3560/2960 series switches and some 4500 with MAB.
the interfaces have the following config:
authentication host-mode multi-auth
authentication order mab dot1x
authentication priority mab dot1x
authentication port-control auto
authentication periodic
authentication timer restart 120
authentication timer reauthenticate server
authentication timer inactivity 600
mab
dot1x pae authenticator
Good luck

Phone won't connect to wifi saying authentication problem

My phone after being connected to sky wifi from sept 2013, has all of a sudden started hardly connecting, and always says 'authentication problem'. I have my iPad connected to the wifi too, but this has also been connecting fine since sept 2013.The connection to my phone drops a lot, and then when it is connected it is very, very slow. It doesn't drop at all on my iPad. Please can someone help me. And put it in layman terms please, thank you. EM

Two things to try. Change the wifi channel on the Sky router/Hub itself, instruction on a post at the top of this forum. And try forgetting the network on the iPhone; Settings->WiFi, and select the network ticked. Select Forget This Network and confirm it. Then reconnect to the Sky router/Hub by selecting the wifi network and entering the password again on the iPhone. Try the latter first, then change the wifi channel on the Sky Hub/router after this step. If you don't have an iPhone, then use the steps appropriate for that phone to basically do the same as above, for forgetting and reconnecting the phone to the wifi network.
