Cisco Wireless :: AIR-WLC-2106-K9 Locks Up Only Power Cycle Will Fix
Apr 17, 2011
I have the following equipment
1 x AIR-WLC-2106-K9 (IOS = 6.0.199.4)
4 x AIR-LAP1131G-E-K9 (IOS = 12.4(21a)JHB1)
All configued ok with 2 SSID's associated to 2 VLANS all operates as expected.However every few 2 to 12 hours the WLC crashes, locks up.Unabale to contact via telnet or browser, will not respond to ping.The LAPs remain up but the WLANS go off air etcOnly a physical restart of the WLC will bring it back.

I'm having a little issue with some Cisco Aironet1242ag WAP's. I receive a call at least twice a month stating that some of the WAP's are not giving out internet connection. What I always do is go to my patch panel and disconnect those WAP's not working and connect them back again so they can power cycle. These WAP's are connected to a Cisco3750g. Once the WAP's boot up, the users can connect to the WAP and connect to the internet.
I don't know if these WAP's are filling up with some information that causes the access points to not connect to the WAN.

We have some 1242 LAPs in a two 5508 controller setup working fine. All LAP are configured to obtain address from DHCP. After first join we usually change some configs like HOSTNAME, AP GROUP, PRIMARY AND SECONDARY WLC. After a software restart or a complete power off/power on the LAPs joins the primary controller and all configuration still there. We now add a 1142 LAP and is does not retain the configuration after a power off/power on cycle, but after a software restart there is no problem. The only way to retain the config is setting the AP with a static IP address.
We use WLC 7.0.116 and we see no errors in the LAP console.

I've just bought a pair of WAP121 for testing and validation. I've set it up properly (user/password, IP, management vlan, NTP, SNMP, 802.1x, etc). So far, so good, everything worked as expected. I've downloaded the configuration to my PC, and also saved it to startup-config. I've powered off the unit, went for a coffee, and powered it back. All my settings were lost.
Tried to restore settings from the file downloaded to my PC, but no luck. After reboot, it was factory clean, no trace from settings in the backup file. I've set it up again by hand, power cycled it, and the **** thing reloaded to default settings.
Faulty unit, I thought, so I opened the other one I have, and repeated the whole thing, but same results. Test were made using the power adapter supplied but also tried with a catalyst 2960 with PoE.

I have an E1200 and if a device - such as my tablet or laptop - is left unused for a period of time - say for 4 or 5 hours - they won't reconnect to the router unless I do a power cycle/reset on the router.

We have a Model WRT54GLWireless-G router. At least once a day it loses it's internet connection. All computers that are wired to the switch that is connected to it lose their internet as well as any wireless devices. I have to manually power-cycle the router to get internet back.

recently bought a new Linksys EA3500 that is connected to my SB5120 cable modem. For two weeks it's been running smoothly but when my cable modem is in need of a power cycle.I power cycle both the router and modem but my connection is lost. it's after countless hours of messing with the two I'll get the connection back but I'm afraid it'll lose connection again, that and I fear I may have enabled bad options.

I have access controls setup on my DIR-825 which work fine until there is a power outage and my router comes back up.I am using Automatic Time Configuration and have the NTP server set to ntp1 [URL]When the router comes back up I checked to make sure the NTP server option is still enabled, and it is, however the current time is totally wrong.To fix this I had to go to the pull-down, select 'ntp1.dlink.com' and then save the settings. After this the time is correct again.This is as bad as not having the Automatic Time Configuration option at all, since I can't guarantee that the power won't go out. I do not have a UPS hooked up to back up the router, nor do I see why I should need one if the Automatic Time Configuration actually worked.know if there is a way of making the Automatic Time Configuration reliable so the time on my router is automatically corrected when the power comes back up?

It seems there's no way to reboot this device from the browser interface. You have to actually go and recycle the power by physically pressing the button.Plus, to setup Port Forwarding you have to reboot the modem.This is a major problem because it means you have to be on the premises to change things like the port forwarding. You setup it up, but have to reboot for it to take effect.

Cisco 2800, 12.4(23b) router has two VPN tunnels to other Cisco devices.
Authentication uses certificates from a PKI CA server. Under normal circumstances all works fine, both crypto sessions up.
After a power cycle (having first saved configs) however, the crypto sessions are stuck in DOWN-NEGOTIATING.
The certificate on the router still looks valid.
The only way to get the sessions back up is to renew the certificate, which seems strange as the existing one appeared to be still valid.

I've setted the unit in BRIDGE MODE, and attached on it 3 LAN devices, 1 PC Desktop, 1 NAS WDBE and 1 HP printer ... OK all config process was right and all my units talk togheter via AP Netgear DNG2000, and so i can use for instance the printer with my laptop too connected in WI-FI N. Now usually, In the night I turn off all my devices (DAP included), and when in the morning I need only the printer used by my laptop, obviously I turn on ROUTER - BRIDGE - PRINTER - LAPTOP but NOT the DESKTOP ... and so the DAP can't reconnect automatically to the router (both the lights AP/BRIDGE are on and fixed) ... I turn on the PC and the BRIDGE reconnect to the world .... BUT I DON'T WANT turn on everytime the desktop !
1) all gears has fixed IPs
2) DHCP server deactivated on the AP main router (DNG2000)
3) no WPS used, only WPA2-PSK (AES) personal keys on all gears
once that DAP-1522 is connected to the router .... all work fine (also when I turn off the DESKTOP).so the workaround is never turn-off the DAP ? I can't believe ... and who will save the energy planet

When our DSL modem drops its connection, even momentarily, the RV220W requires a power cycle before the computers on the LAN can browse again. When I connect to the router, the WAN Information displays the word Connecting, rather than Connected.
We have a DSL modem connected to the router, the router connected to an ethernet switch, and our small business pc's connected to the switch.
Firmware on the router is 1.0.4.17

1552E Rap will "lock" up, and not allow MAPs to connect through it to join. the WLC. Rebooting the Rap will resolve the issue, but the problem comes back and some random point in the future. Prior to rebooting the Rap to fix the issue, the Rap shows as joined to the WLC, but I have noticed that the neighbor details look stale, meaning my MAPs don't show up as neighbors, but other MAPs in the area are in the neighbor list, listed by MAC address. At this time, I can not confirm whether or not the neighbor detials are changing (updating), but I can confirm that my MAPs never show up as neighbors.As soon as the RAP is rebooted, MAPs join the controller again.

A day ago, I was having trouble with my apartment modem, and due to a busy schedule, was only able to do a quick "Unplug and reset" which seemed to work at first, but eventually it stopped working all together. Today, I traveled from my apartment to my "home" home, where the wireless network is set at a "Home" security level. However, my wireless now will not connect at all. It continues to cycle through "Identifying" yet cannot make the connection. It works through a LAN connection however.So far, I've attempted the follow:
- run>ipconfig/all, ipconfig/reset, etc
- winsock reset
- system restore
My computer is a Samsung RC512, running windows 7. Here's the paste from my ipconfig/all:

Every time I use internet applications, browsers, game clients, games, etc. the computer will completely lock up and I am required to manually reboot it. All devices stop working and the only way to get it working again is to hard reset. I'm so fed up with it, and have tried virtually everything. On top of that, I am getting only 1-9 Mbps download speed, opposed to all my other wireless devices, which are getting 34-36, which is what my wired connection is.
Here are my specs:
Core i5 3570k
16GB DDR3 Corsair
1000w Kingwin
Zotac 4gb GTX 680
240 Sandisk Ultra SSD
z77 AsRock Extreme 4 motherboard
D-Link DWA-556 Xtreme N Wifi Card
Windows 7 Professional x64 bit
Also, When first installing the card, I used to get around 34 Mbps, as this started occurring just in the past week or so. It works fine in other computers though and my signal strength is showing 100%.

Wireless router started randomly not allowing any wireless devices to connect to the network. A wired cable worked fine, but not wireless. So we had to unplug the router and then it would work fine.You could see the device, but not connect. We moved our wireless phone a little farther away from the router thinking it was interfering, but still no luck. It didn't matter if it was an iPod, our BluRay player, or a laptop.

my E1000 router locks up and I lose Internet connectivity until I unplug the router's power cord, wait for 10 seconds or so, then plug it back in and let it restart. This seems to be triggered (a.) when I land on a web page with intensive graphics, etc., that takes a while to load, or (b.) if I launch a web page really quickly while another one already is up. it doesn't just happen spontaneously when I'm working on the computer. This computer I'm working on is old and slow, which is why as per my earlier inquiry about having to reconfigure the router and network , I'm looking at changing to an up to date and faster model. I just updated to the latest firmware, probably a week or so ago, but the router was doing this before then and still is doing it now.

My WRT54G router locks up 100% of the time when attempting to connect connect wirelessly to a Samsung Blue Player (Model number BD-P3600). I can connect to it with a cable no problem, but when I attempt to do so wirelessly and type in the password on the Blue Ray player, it attempts to connect but the router locks up and all devices connected to it (wired or wirless) lose connectivity

I'm using the E4200 in Bridge mode and it's handing out IPs from our DHCP server (not acting as it's own). I have about 8 people connecting to this wirelessly to get to our network. For some reason it locked up once every week or two and I have to unplug it (can't even remote into it).

I have a AE2500 USB Adapter. Whenever I go to connect it from my host machine to my VM I receive a Code 10 Error in Device Manager(Device Cannot Start). The VM locks up for awhile then comes to for a moment. Problem stops when the USB adapter is removed.

My e4200v2 which I have been using for about 4 months locks up or freezes regularly - as often as once or twice a week. That is to say the wired laptop can't reach the router and the smart phone does not have a signal. This often happens when there is no phone or computer running. My current firmware is 2.0.37 and it just happened again. The logging capability is absolutely terrible so you can't tell why or when it went down, and what happened just before it went down. I pull the plug on power and when it comes back the log is clean. avoid the freezing/lockup or for logging incoming and outgoing with timestamps?

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

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.
