Wireless :: Username / Password Required For External Hard Drive Access

Aug 26, 2012

I am looking to get access to an external hard drive that I have set up on my wireless network.When I try to do an automated Windows backup (off my Vista based laptop files) on to an external hard drive which is connected to my wireless network (through a Belkin router) I am being asked for a user name and password to access the connected hard drive on the network. The thing is that I don't remember setting up a username and password for the hard drive at all. I can paste single files mannually onto the external hard drive without being asked for a username and password. I did perform an automated Windows backup off my other Windows 7 laptop and was not ask for a username and password. where to find the username and password information ?

Linksys Wireless Router :: X2000 Doesn't Need A User Name / Only A Password Required

Nov 27, 2011

Just set-up a new X2000, loaded latest firmware 2.0.01, configured it via the web UI ('Browser based utility' as per the manual). Connected OK to my ADSL broadband by O2.  Configured wireless, everything OK. Funny it doesn't need a user name, only a password, my prevoius WAG160N could be configured for both.Now I want to configure the Parental Controls, BUT apart from my computer name and an Android phone name, all I see in the Target Device ADD button pop-up  are a list of repeated 'Network Device'.   There seems no way to be able to distinguish which is which device (mix of XP & Win 7 PC's and HP Printer through a separate switch), as it does not show IP address or MAC. 

I thought I may have better luck with the Cisco Connect software (which I didn't use to set-up the router).  I downloaded the latest version 1.4.11194.0, and ran this on another computer with wireless.   Apart from reconfiguring my static IP address to DHCP, and then connecting through DHCP, the software said it could not configure my router. So it never gets to a point where it installs any program on the computer so that I can configure Parental Controls. How do I get the router to show ALL the computer names in the list rather than 'Network Device' or is there a way to distinguish which 'Network Device' is which computer?

Linksys Wireless Router :: 4200 Why Password Required For Insecure Network

Dec 13, 2011

My linksys 4200 was set up some time ago for me, (unsecured) and was working fine.  I was having problems with just 1 desktop that was using a usb wireless adapter, so I went and purchased a new cisco ae2500.  While connecting I used the push button that it described, only it knocked out the network, and all the other computers are now off of the network.  The new network(s) are Cisco_WPS_42526 (secure) and Cisco_WPS_42526-guest.  Not knowing the network key and the guys that set it up are gone, I tried the guest. WHICH REQUIRES A PASSWORD!!!!  I can now not get ANY of my computers online!  How do I find the security, or the password? Why would you need a password for an insecure network anyway?

Cisco Wireless :: AIR-LAP1142N-E-K9 Interfaces Down

Mar 12, 2013

I have a WLC with, let´s say, 30-40 AIR-LAP1142N-E-K9. Since last November the following issue happened 3 times. One of the APs (it´s always the same unit) remains online but both WiFi interfaces appear down. I´m unable to put it back UP like if they were disabled. Then i have to reboot the AP and it starts working again. 

What could be happening? Should i open an RMA for this unit?

Cisco Wireless :: AIR-WLC2106-K9 / AIR-LAP1142N-E-K9 - APS Configuration

Aug 22, 2012

I've just bought an AIR-WLC2106-K9 and 3 x AIR-LAP1142N-E-K9 and I'm having a problem getting the AP's configured. 
Firstly, the controller did not discover the device when it was on the same sub net, I had to plug it straight in which is no good for wireless-n due to the 100Mbps port speed on the controller.  Secondly, when I am editing the AP through the controller webpage, none of the details are saved after applying changes (static IP etc).
I followed the Cisco quick start guide for the controller to get the basic config, radius server details etc in.  It is running software version:

Cisco Wireless :: LAP1142N Not Saving Config

Feb 11, 2013

I have a wireless deployment using a 5508 controller and 90+ LAP1142N lightweight access points.Everything is going relatively well, except I have about 3 that do not keep their config (hostname and AP group) past a reboot of the access point.When they do come up after a reboot, they go back to the default hostname of the mac address and are placed in the default-group AP group.

Cisco Wireless :: LAP1142N Connecting With AIR-WLC2112-K9?

May 29, 2013

I'm in the process of trying to get a used LAP1142N access point connected to my already established WLAN. We currently have 7 active LAP1142N, our controller is a AIR-WLC2112-K9, and I am only trying to add one additional access point. I say this access point is used because we purchased it used, given it's not out of the box and hasn't ever been active in my environment. So far what I've tried is initially connecting the access point on to my network (powered over Ethernet) and consoled in from my desktop. With this, I was able to see the previous configuration so I ran a write erase/ reload. The AP shows a solid green light, but doesn't receive any configuration from the controller even when plugged directly in to the controller (on ports 7 and 8). I'm new to wireless, but familiar with Cisco CLI and web interfaces. I can't necessarily tell if this AP is set to autonomous as opposed to lightweight, but that could be the problem. Otherwise I'm lost. I've attached text files with the boot from CLI and show run from CLI.Let me know any additional information you may need. End note, I'm recieving DHCP (you can tell from boot), but it's not the same subnet as my controller or other active access points.

Cisco Wireless :: Accessing WLAN Via AP Air-lap1142n-e-k9

Apr 17, 2012

We have a set up which includes several air-lap1134n-e-k9 access points. We're having problems with a specific laptop connecting to the WLAN which is accessible via the AP. We can see numerous different SSIDs available and when we connect to either of the two we have set up it says it is unable to connect. One of the connections, let's call it Internet, has Layer 3 security set up. The other connection, Web, has Layer 2 security set up. The laptop can connect to neither. It can, however, connect to other wifi in the vacinity including a wifi hotspot we set up on an Android phone.
The laptop has an Intel Centrino Wireless-N 1030 network adapter with current drivers. The WLAN's we've set up, Internet and Web, are both enabled for 802.11n.

Cisco Wireless :: AP LAP1142N Can't Join Controller - 4402

Apr 11, 2012

I found a recovery image in its flash - c1140-rcvk9w8-mx. I made the AP boot from it by using "set" command and I see that it start booting using this recovery image. Here goes the question. Do all AP settings matter ? E.g. when I run "set" command from AP I see the following:

Cisco Wireless :: LAP1142N Cycling IP Addresses From DHCP

Feb 12, 2013

I have a LAP1142N that is connected to a 3560 nonPoE switch (using compatible power injector) that will not associate to the controller I have set-up. The wireless is existing and I have about 11 other APs connected to the controller with no issues. The AP will pull an IP address from DHCP running on the primary controller. The AP pulls a new IP address in roughly a minute. I set the pool to be 3 IP addresses and set a contant ping to each, there is about 1 request time out before the next IP address starts pinging. I went to the controller and pulled the following message error from the log.

*Feb 13 14:24:58.614: %LWAPP-3-HDR_ENCAP_ERR: spam_lrad.c:4216 Unable to encapsulate LWAPP header for discovery response; AP (APs MAC address)
*Feb 13 14:24:58.614: %APF-3-PDU_ENCAP_FAILED: apf_net.c:771 Failed to encapsulate a PDU for transmission to station00:00:00:00:00:00. Destination IP address not set in L3 mode.
I have tried a different cable, connecting to a PoE switch, different controller, larger DHCP range, hosting DHCP on the distribution switch, I am awaiting console access to the AP since this is remote work. The controller is running Software Version Thoughts?

Cisco Wireless :: WLC 2504 With AIR-LAP1142N-E-K9 Connection Configuration

Dec 6, 2012

I am currently experiencing an issue with a WLC that I am trying to connect 3 new Access Points to of the type AIR-LAP1142N-E-K9 running Cisco IOS Software, C1140 Software (C1140-RCVK9W8-M), Version 15.2(2)JA
I had the controller on firmware and just upgraded to in the hopes to solve my issue. The already connect APs running 12.4 was upgraded without any issues (apart from one - I'll get to that one) and it is now running as before. But the issue with the 3 new APs still persists. I have supplied a screenshot of the AP Join page.
Another issue that arose from the said upgrade was that a previously shutdown AP (of the same type and software version as the ones that upgraded perfectly) got turned on after the WLC firmware upgrade and is now not able to join the controller.

Cisco Wireless :: LAP1142N-N-K9 Regulatory Domain - 802.11a Not Supported

Feb 7, 2013

I have two AP models in my network. LAP1142N-A-K9 and LAP1142N-N-K9. The LAP1142N-A works fine with both radios (a/n and b/g/n), but the LAP1142N-N is getting a regulatory domain not supported problem with the 802.11a/n radio, which is keeping it in the down state. I'm in Canada, and my country code on my 5508 WLCs are set to CA. My WLCs are running firmware version 6.0.  I read over some specs and the difference between the two APs is FCC cfg vs Non-FCC cfg... Not 100% sure what that means.

Cisco Wireless :: Clients Unable To Connect And Get DHCP LAP1142N AP

Feb 5, 2013

I have 19 locations, each with 1 or more LAP1142N AP's in FlexConnect mode, AP's are primed using CAPWAP to my 5508 WLC at the datacenter. The AP's join the WLC without issue every time. I have two WLAN's, one guest and one staff, the guest network is open and obtains DHCP from a WatchGuard XTM33 firewall at each of the remote locations. The staff side is WPA2/RADIUS and DHCP is assigned from the WLC. Each AP is assigned a static IP that is not in the DHCP scope. For example: DHCP scope on the branch firewall is the AP will be assigned static IP of The AP's are connected to a HP procurve switch that has a untagged VLAN, the firewall is using the native vlan 1 and so is the AP.
I have been running this network for over a year and it has not had a single issue until the last two weeks. Nothing on the network has changed or has been upgraded.The issue I am seeing is that clients are no longer able to connect to the AP and do not get DHCP assigned to them. I am able to get it working, if I remove the static IP from the AP, the AP will reboot, join the controller, then begin working, users can connect and DHCP is assigned from the firewall as it should. However, If the AP then reboots, the AP will join back to the controller but no clients can connect nor do they get a DHCP address. So, I then reassign a static IP to the AP again and it reboots, connects to the controller and clients then can connect and get DHCP.i've found several posts on this topic, in fact the patch of unassigning or reassigning static IP is one that I found. I am also waiting on my SmartNet to start up and will be contacting Cisco support as well.

Cisco Wireless :: New AIR-LAP1142N-A-K9 Insufficient Memory To Boot Image

Nov 1, 2011

I just pulled the AP out of the box and haven't received support contracts yet.  I connected the AP to the LAN and added it to my 4402 controller (version with no problems.  Once I set it the mode to H-REAP and it rebooted, it went loopy.  Actually, it boots up, shows a bunch of debug info, then reboots.  The console output is below.  I've tried reimaging (image c1140-rcvk9w8-tar.124-21a.JA2.tar) but still have the same problem.  I checked and although the controller software is old, the AP is supported.

Cisco Wireless :: LAP1142N / WCS V.7.0.172 - Disconnects From WLAN Guest Access

Feb 7, 2012

We have a strange problem. We have a WCS v.7.0.172 that controls our two WLC v.7.0.116 and we have also two "Anchor Controller" WLC
v.7.0.116 for Guest Access.
We use the LAP1142N and every AP has two SSID's. One for internal data traffic and the other one for the guests.
Now the problem is, that even if we have internal and external user on the same AP, the guest users gets disconnected after a few time. Sometimes after 20 minutes, sometimes after 90 minutes...but the user is still working. It's really irregular.

I suspected the issue in DHCP but even on static IP the user is not connected.I dont believe any LAN issue is there cause I connected a PC to the same interface where the AP is connected and it took an IP from the required VLAN (1234) [code]
