Attempting To Authenticate - Unable To Connect To The Network
Oct 22, 2011
I tried changing my wireless settings from wpa2 to wpa, but it wouldn't allow me to connect. I made the change in settings because I read somewhere that it would allow you to connect your blackberry. I changed the wireless settings back to what they were, reset the router, but now the wireless sign doesn't even light up on my belkin router and it always says 'unable to connect to the network'. Something about 'attempting to authenticate'?

My laptop was connecting fine to a Liknsys G router until one day it couldn't connect because it gets stuck to Attempting to authenticate. I have one more laptop, a desktop and an ipad and all connect fine to the network except of my laptop. I removed the network password but nothing again.

I'm having difficulty connecting my desktop to my wireless network. Some details to start off: I'm using a G-Sky usb wifi adapter model number GS-28usb. I recently moved from an apartment with free wifi and I set up broadband with Qwest/CenturyLink. The modem/router is an Actiontec Q1000. The firmware is up to date (I checked) and every other device I bring into the house can connect just fine (laptop, roommate's desktop and laptop, and my blackberry) I'm running Windows 7 x64 Ultimate on all machines, with all updates currently available. My network shows up in the list of available networks, signal strength fine, but when I try to connect, it does its initial "getting information..." in the small box in the corner of the screen, then the box disappears and no connection is made. The status of my adapter at that point will say "attempting to authenticate" and will remain like that even though (apparently) windows has given up on trying to connect to the network. It never gets to the point where it asks me for the passkey. I've changed just about every variable I can think of that might affect this on the router (encryption type, b/g/n, legacy mode, compatibility mode, etc, i've renamed the network, powercycled the router, etc) all to no avail. I've tried to manually add the network settings under wireless profiles, but even though the information I put in is EXACTLY correct, under available networks its says that my settings don't match those on the network. I've tried different wireless adapters, and none will connect, so I've eliminated a faulty adapter. I can connect to my laptop with an ethernet cable, and bridge the connections so I can use the internet on my desktop, but i cannot connect directly to the router.
here is my ipconfig/all:
Microsoft Windows [Version 6.1.7601]

I can not connect to my wireless network from my pc. My laptop is fine. the internet worked like 5 times.. but it's been dead for two days now and everything I try seems to fail.i can see my router in connections, (sometimes not) And when i see it, it says limited acess and works for like10 mins..The OS is Windows 7 ultimate 64bit and im using a gigabyte GN-WB01GS USB WLAN card#2 network adapter. The signal strength is good. Ran all the windows trouble shooters... nothing, though it works wired. After clicking connect im told that it is attempting to authenticate forever and that is all that happens,I dont get why it works sometimes, then doesn't.when the internet works it have worked like 5 times (for 10 minutes) but now i cant even connect to it..Whenever i tried to download SOMETHING, it stopped working. And the internet i had those 5 times was were slow, not 54 mbit net. [code]

I have been trying to re-establish my wi-fi connection for over a day now. I have a Dell Inspiron 1545 with windows 7 and it has two wifi adapters, one is the 1397wlan and the other is a virtual miniport adapter. My carrier is at&t uverse/2wire and my service was disconnected for about eight or nine days and since then I cannot get my wi-fi back. The desktop computer works fine but my network adapters are showing attempting to authenticate and not connected for the miniport adapter. I have tried enable/disable, restoring to a previous date, ipconfig/release, and of course running the trouble shooter for Microsoft. The result is that they can't assist with my connectivity issue and that its either the adapter or my router. I can use the laptop with the ethernet cord but its not practical as the router is downstairs and I primarily work upstairs.

I an currently running Cisco (ACS 5.2.0.26.3) and attempting to get my Cisco 5508 WLC's (7.0.98.0) loaded into ACS for TACACS+ authentication for managment users.
However I keep getting the following error:
*emWeb: Sep 14 14:44:45.931: %EMWEB-1-LOGIN_FAILED: ews_auth.c:2104 Login failed for the user:test_tac. Service-Type is not present or it doesn't allow READ/WRITE permission.
Now I've attempted the step-by-step using the following URL but to no avail.( there are some slight differences in ACS 5.2)
[URL]
Latest WLC configuration guide I could find (Software Release 7.0 June 2010) isn't much useful either.

I just replaced my router (Linksys WRT300N) that decided to take a dirt nap. I hooked up my son's Netgear router that he used to use for gaming, and got every wireless device in the house going pretty quickly - every one, that is, except my desktop PC (Windows XP Pro SP2). It detects my home network, but when I enter the network key (passphrase), it chugs along for a minute or so and quits, refusing to authenticate, acquire the IP, and finish connecting. That wasn't a problem before with my previous router. The desktop has a D-Link AirPlus G DWL-G510 PCI Adapter card. What's the likelihood that my card went bad at the same time as my router? The card is 5-6 years old I think.

For unknown reason I cannot get WLC to authenticate correctly with ACS 5.2. it's very strange in the sense that when I checked the log. ACS authenticates and authorized the WLC 4402 but I cannot log to the WLC. login screen appeared, if I typed user name it jumped to Controller> user: password:
No matter what I typed (internal or external users) nothing seems to work. This is my frustration, I have no problem authenticating routers and switches except WLC 4402.

Our customer has the business needs to authenticate remote users against AD with empty password. I've seen ACS5.1 release note where mentioned about resolved issue: #CSCte72751 #ACS 5.1 drops authentication with empty password.
I tried to authenticate dial-in users through Tacacs and Radius against AD with empty password but without success. ACS points to wrong AD password. Is it possible to authneticate remote users with empty password?

I have allways configured and run LDAP Server Groups authenticating to Active Directory Domain Controllers using LDAP, never an issue, until I hit a Domain Controller running on a Windows Server 2008. I have been unable to authenticate with the common setting with an ASA5510 running 8.0.1.

We have had an active ACS unit for many years now, and we've added a second one, both are 1121 Appliances. The newer one came with 5.4, so we upgraded the older one to 5.4.
We setup replication between the two, with the newer one primary and the older one secondary. Problem is, windows based clients are unable to authenticate to the older ACS appliance. The only problem we can see is that it indicates that adclient is not running, under Monitoring & Troubleshooting, ACS Health Instance Summary.
So... been trying to figure out how to correct this, yet have been hard pressed to find a knowledgebase article that works. So far, Cisco hasn't added my smartNet on the new box so I can get some support?

I am not sure what I am trying to do is possible, so I thought I would pose the question on here. In ACS 5.3, I would like to use an RSA server and AD to authenticate my network devices. So when I log into a router or switch I would enter my AD username, be prompted for my RSA token, then when I enable be prompted for my AD password, or visa versa. how to write an access policy to achive this?

My grandma has a Dell Inspiron 1520 running WinXP and has a Dell Wireless 1505 Draft 802.11n WLAN Mini-Card. The other day I reformatted her computer for her to clean things up and since then I have been unable to connect to the internet. Her computer will recognize the wireless network and connect to it but after a few minutes of trying to authenticate network address it will pop up a little window that says "limited or no connectivity." I've read countless forums on the internet using my computer and have come to the realization that it's an invalid ip address. In one post I read someone provided an ip address, subnet mask, default gateway, and a preferred DNS server code that I typed in which then showed that I was connected with wifi but still says authenticating on the WLAN card.

I'm trying to use 802.1x to authenticate clients on my network with dynamic VLAN assignment from RADIUS. We have IP-Phones(powered by PoE) that only supports EAP-MD5, and we would rather use MAB(it also uses LLDP-MED for some settings) to authenticate the phones using the MAC-range from the phones vendor. The following scenario works perfect:Connect the phone and let it boot up(takes a while) and authenticate with MAB.Connect a computer in the phones data-port and let it authenticate with 802.1x(or fail and reach guest-vlan) However, the following scenario doesn't work:The computer is already connected to the phoneThe phone is then connected to the switch What happends now is that the computer is authenticated using 802.1x before the phone boots up and get's authenticated with MAB. When the phone is ready, it's authenticated with MAB and everything works. However, after a short period(let's say a minute), using `debug authentication all`, we see a "NEW LL MAC: phones mac" message(which is weird since the mac has already been MAB-authenticated), and then we are unable to contact the phone using ping. When I check `show mac address-table` it has now moved the mac from `Port Gi 0/12` to `Port Drop`. However, if I check `show mab interface Gi 0/12` or `show authentication sessions` it lists the phones-mac as `mab auth sucess `.why the first scenario works, and not the second?
The switch is a 3560E PoE 24p with IOS 12.2.58SE2. Sample of the switch-config: network-policy profile 1voice vlan 90!interface GigabitEthernet0/12switchport mode accessnetwork-policy 1authentication control-direction inauthentication event fail retry 1 action authorize vlan 60authentication event server dead action authorize vlan 60authentication event no-response action authorize vlan 60authentication event server alive action reinitializeauthentication host-mode multi-domainauthentication order mab dot1xauthentication priority mab dot1xauthentication port-control autoauthentication periodicauthentication violation replacemabdot1x pae authenticatordot1x timeout tx-period 5dot1x max-reauth-req 1spanning-tree portfast!Btw, when we tried authenticating the phones using 802.1x too (EAP-MD5), there are NO problems in any of the scenarios. However, we want to use MAB instead of 802.1x to avoid the requirement of configuring the phones with a username and password. The RADIUS response was the same when using 802.1x as it is with MAB for the phones (including device-traffic-class=voice AV-pair).

I had to go onto a website last night called "Audible" because I have a payment on my credit card showing and I wanted to know what it was. My pop up browser warned me that the site may contain harmful content but I had to proceed to be able to find out what I was being charged for. I accessed the site via an email. I have tried to open up my laptop this morning and a sign popped up saying a corrupt file had changed my homepage. I cannot click on it to set is as my default. I cannot connect to the internet either, when I click on network places and highlight my usual one it comes up with a message "This is taking longer than usual".

I've recently reinstalled a fresh windows xp operating system onto an old laptop. I've been through some trouble getting the drivers installed, but now I've finally completed that.[URL] I cannot connect to my home's WEP secured wireless network to which I have the password. After I followed the steps detailed in the link, instead of saying "detecting network type," the loading bar says "waiting for the network..." and after about 30 seconds, it disappears and nothing happens.I can connect to my router by directly connecting it with an Ethernet cord without a problem. And I know that the laptop is capable of connecting to a wireless network. I was able to connect to a nearby neighbors unsecured wifi, however it was with a very slow connection due to the distance and weak signal. It will just not connect to my own.

I have a netgear n300 WNR2000 v.2 router (which has the latest fireware as of today) and have connected to it both wirelessly and wired with my netbook. My netbook runs windows xp with sp3 and has all the lastest updates. My 2 pc's on the network are both wired and running windows 7 (both up to date with updates). I had no connectivity issues with any computers on any network ever until I got the pc's with windows 7. The 2 pc's see each other fine and they have zero issues as far as networking goes. Neither pc will interact with the xp netbook, and the netbook will not interact with either pc. I installed the LLTD on the netbook, which did allow the computers to "see" each other on the network maps. However, the computers still do not interact and say they are not on the network, even when trying to use the icon provided from the map to connect. In command prompts, all pc's and the netbook are able to ping each other with ip addresses. Only the windows 7 pcs are able to ping using net names though. When locating via "net view 192.168...", all the computers see each other and even display the appropriate names for the computers. However, using "net view pcname...", again nothing.I have selected netbios over tcp/ip, made sure the workgroup names match on all computers. The "net names" command showed no names saved in the cache.

So I'm currently running window 7 on my msi GT683-R. As of yesterday my internet stopped working, however only on my msi. I'm currently typing this on a borrowed mac using the same network that doesn't work on the other device. It also works on my iPhone. The problem is, neither the wifi nor the wired works on my MSI. I made sure DHCP was on, ran a TCP/IP stack reset, a winsock reset, have restarted my computer/router multiple times, and disabled bonjour but nothing seems to work.

I have a BT homehub V2, I have 2 computers connected via cable, a laptop wireless an iPhone wireless and an iPod touch wireless. The cabled computer is not connecting and neither is the iPod touch, but the iPhone seems to be, as I did a speed test on it, which is giving my usual speed result. I don't no if the laptop is connecting as it's my daughters and I dare not go near it, It does not make sense to me that the iPhone is still connecting. The speed result was around 7mps

Moved into a new place recently, internet has been working fine until earlier today I closed my laptop and went to make something to eat. When I came back and turned my computer back on, it keeps giving me this message when I try to connect. It doesnt ask for a password, it simply tries to connect for a few seconds before giving up. After waiting a few hours for the problem to fix itself, one of my flatmates got home and told me they are having the same issue. I have tried restarting my computer, turning off my firewall and restarting the modem.

My son's laptop suddenly stopped being able to connect to the internet via wireless. I can see it okay but just unable to connect. I've checked the drivers and they are up to date. It shows on my network when wired and I've checked with the virus software and I can see no reason for it to be blocked.

i cannot connect to a certain wireless network. The router can take upto 4 laptops and this one will be the third so itis not a question of to many.All the other laptops can conect to the router when the pass key is put in but this computer will not. This computer will connect to other networks but not the one at home. When i put the pass key that it asks into the computer it says that it is not the right one. What am i doing wrong or is there something missing from the computer. Not very experienced at this so be patient and spell it out in laymen terms

I don't know why psp doesn't show the 10 digit key. Also, the same issue happend 6 months ago and i was told psp network is closed as people ids have been stolen so i returned my psp and it seems i will have to return it again.

We have 2 HP Pavillon laptops working with a Netgear DG834GT wireless router and both working fine until a week ago. Now one cannot connect wirelessly (but can using ethernet cable) the other is working fine. ISP is Sky. Anti virus on both laptops is Bullguard. It does connect for a minute or so but with poor signal quality and speed of 1mb ps and then drops connection. At first it said unidentified network but after various attempts trying to resolve it does now actually say Home Network but ipv4 connectivity which should say internet says no internet access. It does go back to unidentified network and then back to home network intermitently. The only thing that has been done recently was that my husband connected a Samsung Galaxy 2 Tab to his laptop (daughters christmas present) to download items to it and whilst connected he noticed that Samsung Mobile MTP Device installed something. Could this have caused an issue. He cannot see how to remove this. Below is ipconfig from both laptops
The first one is working fine

We have 2 computers the main one running OS XP and mine running Vista. Previously, we had no problems with my computer finding the main on the network along with the printer. But now the main computer can see mine (printer and PC) but I cannot connect to the main. Mine does not see the printer nor the PC. We are both running the same virus protection, which is Norton. I really want to use the main computer's printer, which I was able to do until for some reason now I go into networking and it is not there. I know it is marked as shared. When I go into setup network printer and type the name of the printer a window pops up "The printer sever spooling service is not available". I have uninstalled the printer software and drivers and reinstalled but still not showing up on the network?
When I click print a document the printer I am looking for is there but it shows as offline, which it is not. I am not 100% sure but seemed to occur when we switched from Mckfee to Norton?
