Actiontec Q1000 - Stuck In Attempting To Authenticate?

Aug 31, 2011

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]

C:UsersPancho>ipconfig/all

Jul 29, 2012

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]

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'?

Cabling / Cards :: 1397 WLAN Adapter Showing Attempting To Authenticate?

May 3, 2011

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.

Ping Time Out When Attempting Tracert / Traceroute?

May 15, 2012

I'm working as a network engineer for a service provider, and we had just gone through a pretty large scale upgrade throughout our network and service.But not long after the upgrade (or maybe ever since the upgrade, we can't confirm this because we probably missed it out due to many other links to be tested), we met a peculiar problem.Everything seems to be running fine most of the time, but there has been some weird 'ghost-like' activity which have been causing inconsistent network disruptions. At times, certain portions of the network can't communicate with other subnets.And most obviously is the problem with a continuous ping and a traceroute simultaneously. Ping is usually normal, but until a traceroute is attempted, it times out at the same time as tracert fails to obtain the route.Besides, performing a ping from the 2nd closest hop address, 10.250.253.251, which is a cisco layer 3 switch also has problems, the results shown are as belowType escape sequence to abort[CODE]

Attempting To Get HP 4000 Printer Configured And Working?

Oct 29, 2011

So all of a sudden the trusty HP 4000 stopped printing. A little bit of troubleshooting and I found out that the problem was the JetDirect card. I purchased a new one (615n - same model as the old one), installed it, ran a printer configuration page, confirming I have an IP (192.168.x.x) and subnet mask (255.255.255.0), config by DHCP.Also, ran a ping test and it appears to be fine?

The Connection Was Reset Error When Attempting To Load Certain Sites?

Apr 11, 2011

Ok starting about an hour ago I seem to be having a problem accessing youtube as well as Facebook & now Microsoft?I have done some searching around and tried a few of the suggestions I found including; trying another browser (happens using both Mozilla and IE), clearing internet cache, unplugging my modem for a minute then plugging it back in, etc, and so far none of these have worked. I did get youtube to work once since then long enough to upload a 10 sec video but once it was uploaded and I tried editing the video details I once again found myself taken to the page that says The connection was reset.

Cisco :: Attempting To Use SNMP V3 Between 2900 Router And SpiceWorks

Jan 23, 2013

I am attempting to set up snmp v3 monitoring of my 2900 series routers from the third party Spiceworks utility.  My snmp config on the router looks like this:
 
SNMP-Server view Westv3View internet included
SNMP-Server group Westv3Group v3 priv Read Westv3View
SNMP-Server user Westv3User Westv3Group v3 auth MD5 <password1>  priv DES

[Code]....

I have set the logging level on the 2900 router to informational and see no errors of any kind popping up when I try to scan the router from SpiceWorks.  Spiceworks just returns a generic "unable to contact host" message.

Cisco Firewall :: Access-List Traffic Control Attempting To Block RDP 3389

Nov 7, 2012

I have an ASA pair configured to replace a router that hosts a collection of IPSec Tunnels.  Tunnels appear to work.  I am lab'ing some additional controls that I would like to implement.  On the Production Router that i plan to replace with the ASA's the current Tunnels are all wide open (all traffic allowed to pass).  I was hoping to lock things down a little without having to reconfigure all of the Tunnels.  My though was that an ACL on the Inside Interface blocking selected traffic Out (so into the LAN) should not impact the stability of the Tunnels but allow me to restrict some traffic from entering the LAN.  One port that I was attempting to block is RDP 3389.  When this ACL is applied to the inside interface it does not block Port 3389 at all.  What am I missing?  Is it that the trffic is being allowed because it is coming through one of my 'open' Tunnels? 
 
Shouldn't IPSec Tunnel traffic be processed by the Inside Interface ACL just like all other traffic?
 
access-list 145 deny   tcp 192.168.30.0 0.0.0.255 10.187.10.0 0.0.0.255 eq 3389

access-list 145 permit ip any any
 
ip access-group 145 out interface Internal
 
This work great on a 2821 Router, but not so much on the ASA.

Cisco :: New WLC2112 Can't Authenticate Anything

Mar 17, 2011

We replaced a WLC2106 with a WLC2112 and the 2112 can't authenticate anything. Both WLCs have the exact same configuration on them. We are using a RADIUS server to do MAC authentication. Both WLCs have been set to use no delimiter in the MAC filtering.

When the 2106 is in place, we have no issues and all allowed devices can authenticate without issue. However, when the 2106 is removed and the 2112 is powered up, every single device fails authentication and is put on the exclusion list. When we check RADIUS, it tells us the devices fail because they are locked. We unlock the device's account, and 5 minutes later the 2112 has screwed something up and they are locked again.

Cisco Switches :: Cannot Authenticate SG-300-10 With RADIUS

Jan 30, 2013

I have been trying to set this up for like 4 hours. What a waste of time. This should be as easy as punching in the IP and password for the radius server. It isn't.I have a brand new SG-300-10. LATEST firmwawre, I just updated it about 5 minutes ago. 1.2.7.6 I think.This is what I have done so far in the GUI: (I have CLI access too if necessary)

Security > RADIUS and entered my radius IP/secret there.
Security > Access Management Profiles > Create new template called ALL that permits access to all applications. Set it as active also.
Security > Management Access Authentication > For HTTP and SSH

I put RADIUS first then Local second.My radius server works. As I type this message I am logging in via radius with OpenBSD/Centos even Fedora. (If OpenBSD can do it, these switches can do it.)But whenever I try to login with RADIUS credentials to my switch, I get no logs or any connectivity reports on my radius server? Is the switch even attempting to contact the server?  The logs dont show anything regarding RADIUS. I am trying a reboot now, but I don't think that should be necessary.Is there a step I missed? When first looking at this I expected it to be done in 5 minutes. I have been on this for lik 4 hours. Isimply want to login to the administration console (web gui) using RADIUS credentials.

Cisco AAA/Identity/Nac :: Cannot Authenticate AD For Tacacs ACS 5.0

May 24, 2011

I think i've got everything set up to authenticate against AD for Tacacs+ device logins.  When i check the logs, i see:"24408 User authentication against Active Directory failed since  user has entered the wrong password".  This leads me to believe that it is checking AD correctly, however if i enter the password correctly for the same AD user, there is no log at all...no pass, no fail.
 
If i look at the Tacacs debugs on the switch, i see the following:May 25 10:55:07.927 CDT: TAC+: ver=192 id=874699084 received AUTHEN status = ERRORMay 25 10:55:09.932 CDT: TAC+: send abort reason=Unknown

Obviously the switch is communicating to ACS, and ACS is passing info back to the switch.  ACS also appears to be communicating effectively with AD since it knows when i put in an incorrect password for the specific user.

Authenticate Through Captive Portal Using HTTP GET / POST?

Mar 16, 2012

I work at a public library, and our wireless network is controlled with a captive portal. I am using the app Tasker on my Verizon Galaxy Nexus (Android 4.0.3) to do things like automatically silence the phone when it connects to the wireless network. What I'm hoping to do is get it to also automatically authenticate with the captive portal. I know this is possible on a PC, but I'm not sure how to implement it with my phone. Takser allows for using HTTP GET of HTTP POST. With GET I have fields for "Server:Port", "Path", "Attributes", "Timeout", "Mime Type", and "Output File". For POST I have "Server:Port", "Path", "Data", "Timeout", "Content Type", and "Output File". Here is documentation about these two methods:

Quote:HTTP Get Send an HTTP GET request to a webserver.The response code is stored in %HTTPR. A response code of -1 indicates a problem making the request. Any returned data is stored in the variable %HTTPD if the content type is text-based (max 4K).

Example: running a script

Server:Port: [URL] [no port specified, use port 80]
Path: cgi-bin/palpable.pl
Attributes: [must be separated by newlines, no spaces please]
colour=pink
scent=rosy

AAA/Identity/Nac :: Authenticate LAN Users Via Cisco 2911

Feb 9, 2012

We have remote users that dial-in over ISDN to a Cisco 2911. We have configured AAA to pass the authentication off to a RADIUS server. Once successfully authenticated, the router permits the users to access a single web server. However, we need to do some testing in our test environment, but unfortunately we don't have an ISDN line to test with. We have created a little environment in our LAB using a 2911, a switch, a RADIUS server & web server. I was hoping that we could simply create a "user" VLAN off the back of the 2911 to simulate our remote users, and access the web site from the test usr PC's over the LAN. I was hoping that the 2911 would be able to intercept the connection and pass the authentication off to the RADIUS server (as it does with the PPP ISDN traffic). But I cannot find anyway to do this, because I can only configure AAA to offload either PPP traffic or telnet/ssh connections to the router itself.
 
In summary what I want is for a user to access an internal web site over a LAN interface of a 2911 - but have the 2911 authenticate the user via a remote RADIUS server first. Is there a way to configure a 2911 (or any router!) to do this?Is the answer to configure port-based authentication (802.1X) on the switch?

Cisco AAA/Identity/Nac :: Set Up ACS 5.3 Administrator Accounts To Authenticate?

Jun 3, 2012

Have set up a pair of ACS 5.3 servers and have set up device administration authentication be passed through to an RSA server via RADIUS. All works great.
 
What we want to do is go a step further and set the system up so that ACS Administrators also have to authenticate to the ACS system by RSA via RADIUS (the same as the Device Authentication we've set up) for ACS administration tasks.
 
Looking at the options available in the ACS Administration setup (administrator accounts etc) there doesn't seem to be an option to authenticate via another method apart from a local administrator account on the ACS.
 
Is it possible to do this?

Cisco AAA/Identity/Nac :: 12520 Windows 7 Cannot Authenticate To ISE

Aug 21, 2012

I have seen couple of people with win7 cannot authenticate to ISE: 12520 EAP-TLS failed SSL/TLS handshake because the client rejected the ISE local-certificate.I've thought of this: Maybe get a 3rd party cert (go daddy) and have that installed in ISE.I know i do have to make a CSR Cert.Sign.Request that matches cn=primary.ise.mydomain, would I also need a cert for secondary?
 
If I use LEAP as a preferred protocol then it doesn't ask for cert and users are authenticated successfully.I know they have to say do not validate cert and all that but sometimes it doesn't popupt to them they just can't get on.Again maybe going wtih 3rd party certs will make it easier while benefiting from using PEAP?
