Cisco Wireless :: 2106 Not Detecting That Rouge Is On Network
Jul 6, 2011
I have a very basic WLAN setup with a 2106 controller and 3 (will be 4) 1140 APs.As part of securing the network I have been testing the rouge detection. The system has no trouble detecting and shutting down honeypots. I would like to also automatically shut down Rouge on Wire points. The system sees my test AP just fine. And I have it completely open (no security). But the system never detects that the rouge is on our network so no action is taken. I can connect just fine to the test AP with no encription using DHCP and communicate with everything on the network just fine.Is there some setting I am missing that allows the APs to detect that an AP is on wire?

Anyway, I am looking for a way to discover host names of Apple devices (namely iPods and iPhones) that are on our network. I've tried a number of programs like Nmap, Advanced IP Scanner, and LanSpy to name a few. All of them will report back the MAC address with no problem but no dice on resolving the host name.
My goal is to use the host name to identify the device, and ultimately the person with the device. Any thoughts on how I can go about this? Is there a setting in Nmap I'm missing or perhaps a better program to use?

basic question regarding the switchports on the rear of the 2106 controller. How do I configure them for use? I'm using port 1 as my uplink to a trunk port on an ASA and my network traffic to the management interface and guest vlans is all working as expected, but when I plug anything into any of the other ports, they get no addresses from my dhcp server (the ASA). I see nowhere to configure which vlan to tie the ports to or anything. I suppose I'm more used to a catalyst or ASA where I can just pick the ports and vlans (or trunks) I want to attach them to. [code] Again, all of the existing network functionality (private and guest network) is all functioning fine so I'm pretty confident I have the above configured correctly, I just cant make any progress on the WLC ports 2 - 8.

I am new to configuring WLC's. Our small business (5-15 wireless devices + 15ish wired) is trying to use a hand-me-down WLC and AP for our office wifi. We have a WLC 2106 directly connected to a 1231G-A-K9 via the WLC's port 8 POE. I am aware Cisco does not recommend this method, but we do not have a configurable switch at our disposal. We do not need separate VLAN's therefore I have left everything untagged. The AP has a static IP setup to allow communication to the WLC since it did not pull one from the WLC.
The AP is getting the correct network information and is showing up on the WLC monitoring page. I am able to connect to the new wireless network and able to ping between devices connected to the same AP. Now here is my question/issue. I cannot get communication from the WLC/AP to the rest of our network via an unconfigurable Netgear switch (FS605v3). After connecting an open switch port from the Netgear switch to port 4 on the WLC, I am lost. I tried giving port 4 on the WLC an address on the office network, but I receive an error stating "the IP information conflicts with another device".
Here is what I have setup on WLC
Virtual - 1.1.1.1
MNG IP-192.168.10.10
AP MNG Ip- 192.168.10.11
Subnet - /24
Gateway - 192.168.10.1
DHCP - 192.168.10.250
DNS - 192.168.10.250
Static Address on the AP's fa0-192.168.10.15
Attempted port 4 setup on WLC
VLAN identifier 0
IP- 192.168.10.25
Mask - /24
Gateway - 192.168.10.1
Port - 4
Our office network setup:
Subnet - /24
Gateway-192.168.10.1
DHCP - 192.168.10.250
DNS - 192.168.10.250

I have an issue with the Wireless Network. I have an old Compaq Presario V2000 laptop with WIN XP SP3. I formated the laptop OS and installed all the required drivers. I have a Dlink DIR 300 wireless router to connect to the Internet. I switched on the Wireless button; When I tried to connect to my network in Network connecction, I can't see my SSID displayed in available netowrk connections, though I can see others available connection there. I checked, whether my Router is broadcasting the SSID or not, and yes it is broadcasting. I tried with the security type as "WPA-PSK" with AES as well as with "WPA2-PSK" with AES, nothing worked for me. FYI, my room mate can easily access the network on his Sony Vaio CS 15 laptop with any of these two security type.I am fed up . I tried rebooting the router as well as my laptop multiple times.When I manually connect to my network SSID from "Wireless Network" tab in connection configuration, I see a "X" sign over my SSID with a Tower mark.

I have a Lenovo laptop, and all of a sudden the wireless just vanishes.I notice that just before it cuts out, the music I am playing stutters for about 10 - 15 seconds before it happens. when it happens it cant detect any wireless and when i try to trouble shoot the issue it just tells me to plug in an ethernet cable. I check the wireless adapter settings in the device manager and it's working fine, I uninstall and re install. same problem.what I do find is, if I put the laptop to sleep and wake it up, it SOMETIMES works, but I can be doing this for 20 minutes or after one attempt another weird thing is, if I start it in safe mode it works fine. I have tried to look for all solutions on the web, tried everything, nothing works. currently it's working, but who knows it may cut out at any point..

I've a WLC 2106 and it is running IOS version 7.0.240. I am trying to setup a wireless mesh and used the Ethernet bridge port on the MAP to extend the network. The wireless mesh works fine but I can not get the switch to work that is connected to the ethernet port on the MAP.I'm using two different Access points. I'm using a Air Cap 3502i as the RAP and a Air Lap1142N as the MAP.The switch port that is connected to the RAP and MAP is configured as the following:
switchport mode trunk
switchport trunk native vlan 2
switchport trunk allowed vlan 10,20,30,40
[code]....
The wireless mesh between the RAP and MAP works fine. I can connect a device to the MAP wirelessly and access the network with no problem but I can not get anything to work that connects to the switch that is connected to the MAP ethernet port.

I have just taken delivery of a new Inspiron N5110 with an Intel Centrino N-1030 wifi card. I also have two dual band routers (LInksys WRT600N) in different locations in the house.
My problem is that the laptop is detecting my routers Wireless-G signals but NOT the Wireless-N signals. I have checked to ensure that the N-1030 card has 802.11n Mode set to Enabled and have also tried both setting under "802.11n Channel Width for band 2.4" (i.e. Auto and 20 MHz Only) with no success.
My routers are configured with the Wireless-G signal only on 2.4 GHz and Wireless-N only on 5 GHz. I found this to be the best setting to avoid interference from neighbors wifi and cordless phones and have been happily using Wireless-N with my other Dell laptop with no problems (XPS M1530 with Intel 4965agn wireless card).Does the N-1030 card not work with 5 GHz Wireless-N?

My Toshiba Satellite Pro laptop has suddenly stopped detecting my wireless network. IT detects every other network in the area but mine. Other computers in the house have no problem detecting and connecting.Wireless is enabled, it happens no matter how close or far from the router. The network is set to broadcast the ssid, etc. I have not changed any settings on my laptop or router, this has suddenly started happening. Have updated drivers to no effect.Occasionally, the network pops up when I re-start the laptop. Rarely works and sometimes it will detect the network, then fail to connect, then the network can't be detected at all.

The rouge access points being detected by the 5508 WLC are not showing up on the Context Aware tab of NCS? I have a MSE 3310 installed and configured and it shows to be syncronizing with the WLC. I'm sure I am missing some part of the configuration just not sure where.

I have just given my Mum an old Dell desktop computer of mine. She has BT Broadband with a Homehub. I have connected everything up and installed the Homehub software on the computer but when it tries to search for the network connection via the BT software, it keeps saying the network card can not be detected. The network cable is plugged in and working. All the drivers are up to date.

I am using a gateway nv53a laptop with windows 64 bit. I actually have 2 of them. Internet worked fine for a couple years then it just stopped. I cannot connect through wired or wireless. Icon says no connections are available. When I trpubleshoot it says there is no driver installed. I have already tried downloading and installing the drivers. In the device manager it doesn't even have network adapters listed unless you go to view and show hidden. Then it only lists a bunch of miniports and a teredo tunneling pseudo interface. No network adapter is listed. I have do a factory reset and have even taken the wireless card out of my other laptop and installed into this one and it still doesn't recognize it. Running out of options.

For some reason, I cannot connect to my new build, yet everything else in the house connects.I thought maybe too many things were connected, so I unplugged everything and it is failing to work still. I am using the built in WiFi from my MOBO, and my antenna is detecting an excellent connection, but when I connect, it was giving me issues.

I have an HP Pavilion notebook that was given to me by a friend who had upgraded to a new computer. Due to the fact that she no longer remembered the password to the computer I did a clean install of Windows Vista Home Premium to gain access to the computer. Unfortunately, while the computer seems to be running perfectly, when I attempt to find network connections my computer not only can't find wireless connections, but it doesn't even allow the option of manually creating a wireless connection under my Internet options.My computer has a built in NVIDIA nforce Network controller listed under my network adapters and when I check its status it states that it is working properly, yet it doesn't detect any wireless networks. In addition to this, I've read online that the wireless indicator light on my computer should switch from orange to blue when turned on, but even with my wireless switched on the light remains orange.I've also clicked the update drivers option on the NVIDIA network controller, but it states that the drivers are current and changes nothing.

We recently purchased a bundle of 3 1042N AP's with a 2106 WLC. I am able to get the controller on the network and am able to manage it through the https web gui. I am now trying to add one of the AP's to the controller and am getting an infinite loop on the AP upon bootup. I tried looking up the solution but could not find a good article that pertained to the problem I was having. One thing I did notice is the time on the AP is way offset, but when I do a clock set to change it to the actual date it doesnt stick on the next reload.
Here is the output:
using ÿÿÿÿ ddr static values from serial eeprom ddr init done
Running Normal Memtest...
Passed.

I hava installed a WLC 2106 with 4 1252 Aps. Some laptops has dual radio wireless card, but others has just 2.4 Ghz card.
I have one SSID with WPA2/AES and 802.11X authentication.
With the laptops with dual radio the speed is in 300 Mpbs, but when is single 2.4 radio the max speed is 70Mpbs
If i use a 1252 ap with autonomous IOS, SSID with WPA2-PSK/AES this laptops single in 2.4 works to 144 Mbps
is there a knowed issue about 802.11x in 2.4 Ghz or i need to make a different configuration to can work in 2.4 with a speed of 144 Mbps?

I got my final assignment from school, and my teacher asked me to configure 2 Access Points (1200 series) directly on a Wireless Controler (Cisco 2106). I can't ask my teacher for any questions, cause he doesn't know how to configure it also, THAT's why he's asking me to do it.I've learned a lot of things about the default static interfaces (the "management" and "ap_manager" interface), but i can't seem to fully understand how to configure it.I want to use the Internal DHCP server of the WLC. How I can get those 2 Access Points working on the WLC. I only seem to get DHCP issues.
This is what i've done:
- Leave the configuration of the "management" and the "ap_manager" default (172.16.1.30 and 172.16.1.30). Bound to port 1
- Made a new interface "AP1" with IP-Address 10.0.0.10 (/24), default gateway 10.0.0.1. Primary DHCP server: 172.167.1.30
- Made a new interface "AP2" with IP-Address 192.168.1.10 (/24), default gateway 192.168.1.1. Primary DHCP server: 172.167.1.30
- Made 2 DHCP scopes within the 192.168.1.0 and 10.0.0.0 networks.
For some reason, when i boot up both AP's, the won't get any DHCP address.

We have a 2106 that was configured by a former employee. No one left in the company is qualified to configure it. The wireless guest access used to work fine. We'd configure a guest user account. They would connect to the guest wireless, open a web browser and login. For some reason now there is no prompt for login. People can connect to it and get an IP address, but that's it. No login prompt or anything else from there.User Login Policies was set to 0 and I put it to 8. That didn't do anything. Under Web Auth > Web Login Page it's set to Internal (Default).

I setup a mini wireless LAN network lab with a not for resale 2106 wireless lan controller and a sales air-lap1242ag access point. I do not have a DHCP and DNS in my lab environment. I have configured the WLC with the basic configuration using the CLI wizard, i also configured the WLC as a DHCP server for clients that will be connecting to the APs associated to the controller.
I powered up the AP and connect the ethernet port directly to the controller, the controller issued an IP address to the AP, the AP downloaded a new operating system from the controller but failed to join the controller.
I check both debug message on the controller console and the trap messages on the controller's GUI and it say the AP could not download a configuration from the controller and it is beacuse of invalid license. Below is the trap message:
Configuration Phase Statistics Requests ReceivedResponses SentUnsuccessful Request ProcessedReason For Last Unsuccessful AttemptLast Successful Attempt TimeLast Unsuccessful Attempt TimeLast Error SummaryLast AP Message Decryption FailureLast AP Connection FailureLast Error Occurred Last Error Occurred ReasonLast Join Error Timestamp
Also, I tried to log into the GUI of the AP using the both the username and password ''Cisco'' but I cannot get into the device. I can only get in through the CLI. In the CLI, almost all the commands I enter gives an error the it is disabled. I don't know what to do any more, I want to know if the access point is faulty or i am not doing the right thing.

I have a WLC 2106 and 1242AG.it's a hotspot configuration.So in WLC, under controller tab, i have set my ap-manager ip, my management ip, my virtual ip (1.1.1.1) and my hotspot network range ip.I set also a DHCP range for the hotspot network.
In Wlans tab, i set my hotspot wlan, with no layer 2 security and for layer 3, i set none for layer 3 security and i use web policy authentication.I use local authentication and i created under security menu, under AAA tab, 3 local net users.
From pc number 1, i get ip from dhcp, and i have authentication web page, authentication is ok and i can surf on web.From pc number2, when user 1 from pc 1 is connected, i get ip from dhcp but i have not the authentication web page, i have not DNS resolution.when i try https:1.1.1.1/login.html, i have no answer.
And when user 1 is de-authenticated, the user 2 can surf on web.So only one user can surf at the same time. not good for a Hotspot.

I have a problem with Cisco WLC 2106 (SW: 7.0.98.0) and LAP1262. The client roams to new AP, associates with the new AP and authentication (WPA2 with EAP-TLS) runs fine until WPA2 key exchange.
The first WPA2-Key-paket from AP (1 / 4) is sent twice. On a closer look at those packets with Wire shark, i've found out the first is encapsulated into a 11n-frame (A-MSDU). The resent frame isn't. This figure shows the first WPA-Key-packet:
The next figure shows the 2nd key-packet, without 11n-encapsulation: The problem, that occurs a very long roaming-time with about 5 seconds. As you can see on second figure, the second wpa-key is sent 5 seconds after the first.
Some details:
Client: Tablet PC with Intel 6230 agn
Controller: Cisco WLC 2106
AP: LAP 1262
Controller SW: 7.0.98.0
Encryption: WPA2-AES
Authentication: EAP-TLS
This problem occurs just on 5-GHz interface with 40 MHz channel bandwidth.

I have been having problems with a 2106 WLC which seems to have developed a fault. I cannot console into the device (although I can console into the ap1131ag showing no fault with the RJ45 - 9 Pin) and the device is no longer showing up in any of the possible I.P ranges.
Its showing a power light and a status light on the front panel, the Ethernet ports light up like a Christmas tree when a device is connected and the power supply is putting out a solid 47.7v.
Has anyone experienced anything like this before and can anyone suggest anyway of breathing life back into it?

after an unplanned power outage the WLAN in our office has stopped routing. Clients can associate and get an IP address from the DHCP server on the controller but cannot get past the controller. A PC on the LAN can ping the default gateway of the SSID (dynamic interface) but cannot ping the client. Attached is a diagram of the setup. I am trying to find out how to add a default/static route via the L3 switch that the controller is connected to but am unable to do so either through the CLI or GUI. The controller (AIR-WLC2106-K9) is operating on ver 5.2.157.0.
