Feb 19, 2013

After the upgrade of the WLC 5508 to version 7.4 the 1142 access-points LED blinking rapidly cycling through blue, green, and red. I found the following information to this behavior: "Access point location command invoked"
The configuration didn't change. How can I switch this function?

Cisco Wireless :: 1142 - Wi-Fi Speeds Fluctuating Rapidly

Nov 28, 2012

We have approximately 150 1142 LWAPP's deployed in our facility. Recently we started getting complaints about speed issues (90% are using G 10% N). Upon investigating we found that the speeds are fluctuating rapidly. Everything from 54Mbps down to 1Mbps and back up again. I've confirmed that this will happen while standing next to an AP (and confirming connectivity to it), however I cannot find anything wrong or anything that has changed with our configuration. We are a large facility and it is happening all over the campus, so I'm fairly certain it isn't any type of 'normal' interference.

Cisco Wireless :: Aironet 1140 First Time Install - Blinking Red / Green / Blue

May 28, 2013

I'm installing the first out of 10 Aironet AP's with an inline injector. The lights on the Aironet and alernating blue, green, red. I know the error code is for DHCP, but when I plug it in I see the AP on my DHCP server and it does pull an IP address. I can ping the ip address, but I cannot access it through my browser.
I have tried deleting the entry out of the DHCP and power it back on again. I have also tried another unit with the same results. I don't have a RJ-45 to serial cable.

Cisco Wireless :: 1142 AP LED Flashes Green?

Aug 11, 2011

I have 3 1142N AP's.  I plugged them in one at a time here at my desk and they work fine.  When I take them upstairs and install them only one of them works.  I can move the working one to the other locations and it still works.  The LED flashes continously green on the other two.

Cisco Wireless :: 1142 Access Point Blinking Green

Feb 15, 2012

I'm having a strange issue with an 1142 AP.  I have a 5508 WLC at my corporate HQ and have AP's in many locations, connected by MPLS WAN.  I have one site where the 1142 is blinking green and doesn't associate with the WLC.  I have tried a different switch port with the AP (didn't work) and I know that the switch port is good because I have a 1252 that works just fine at this remote location.The really weird part is that the AP is blinking green, but the switch port shows that it is not connected and the green port light on the 3560 switch is not lit.  I have verified wiring in the closet, but unfortunately the 1142 AP is hanging 40ft high in a shop and I don't have access to it.Is it possible that there's a bad rj-45 termination that is allowing PoE to the AP, but no data?

Cisco :: 5508 - Guest Wireless Traffic To Blue Coat Web Proxy

Jan 17, 2012

In my lab I have a Guest Wireless network setup and fully functional. Here is a brief diagram:
Client -> AP -> LAN switch and WLC-Foreign -> Core router -> DMZ switch and WLC-Anchor -> Edge Router -> Internet

I have NME for credential management on the LAN as well.The WLC-Foreign is a 5508.In my DMZ, I have two networks - 1 for normal DMZ management and 1 for Guest Wireless.
I now have to add a Blue Coat web proxy appliance into the DMZ and have Guest Wireless traffic pass through it. I have tried multiple scenarios including connecting the WLC-Anchor to the Blue Coat directly and making the Blue Coat the gateway for my Guest Wireless network. Any good design for the DMZ networks and/or routing to enable the Guest Wireless traffic to go to the Blue Coat and then out to the Internet?

Cisco Wireless :: WLC 5508 / SW / 1142 AP / Clients Getting Dropped?

Apr 14, 2013

We have deployed a WLC 5508 w/ SW version, 1142 AP's & open authentication w/ MAC filtering. Clients are randomly getting dropped with "Limited Access" shown in Win 7. In this state, the client machine is unable to ping the gateway and sometimes lose their DHCP assigned IP as well. A manual disconnect/re-connect to the SSID is required everytime.I ran a debug on one the clients stuck in the "Limited Access" state (debug client xx:xx:xx:xx):

Cisco Wireless :: WLC 5508 / 1142 - Range Coverage

Jul 26, 2012

We did wireless coverage testing using some 1142 units in autonomous mode, and got a satisfactory result, but upon converting these test units to Lightweight and adding them to our WLC5508 controller, the coverage has decreased noticeably. 

Any tips or tricks to getting lightweight 1142 APs to have a range as far as the same hardware with autonomous firmware?

Cisco Wireless :: 1142 / 5508 - User Switching Every Few Minutes Between 2.4ghz And 5ghz?

Aug 20, 2012

This  first started when a user said they were getting disconnected and  reconnected a few times a day to our wireless network.  He is in a  remote office with a 1142 which is set to H-Reap talking back to our  5508.  Our WLC is running 7.0.166 The laptop has an intel ulitmate 6300agn wireless card with the latest 15.x drivers.
We are using an SSID with wpa2 and 802.1x auth back to our ACS server using PEAP with our windows credentials.attached is what i am seeing on the wcs troubleshooting page.When i do a debug client on the WLC i see many reauthentications coming from the client on the different radio.

Cisco :: 5508 / 1142 - Machine Certificate Will Not Be Recognized

Target is Songle Sign On wih Machine Cerificates against AD. For testing purpose we tested with EAP-PEAP/MS Chapv2 and Machine Auth, works fine. Now we installed a Machine cert in the Machine cert Store (no User Cert) and reconfigured the WZC for using certs and Machin Auth. What we see is an Error Message in the System Tray that there is no certificate available. We checked it again, the MMC shows us a Machine cert in the Store.

Cisco :: 5508 / 1142 / APs Won't Rejoin After Controller Outage

Sep 22, 2012

We recently had a power outage where most of our AP's were down as well as our controller.  When everything came back up most of the AP's didn't rejoin the controller without me resetting all of them.  It seems as if the AP's might have booted up before the controller was up, but shouldn't they just try to rejoin at a later time?  They didn't rejoin for 48+ hours on there own so I'm assuming that they were not ever going to re-join.  All I had to do to fix it was power them off and back on and everything worked.
DHCP is on the local switch where the AP's are powered from so that's not a problem, and they had connectivity to the controller the whole time.
5508, and 1142's.Software version on the controller.

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?

Linksys Wireless Router :: WRT54GL Broadcast Keeps Cycling On And Off

Sep 22, 2011

I've had a WRT54GL ( for about a week now ) with no real issues.  Today my wife mentioned that the net's been flaky  ( wireless nto hard wired ).  I originally noticed what seemed like minutes for my desktop of laptop to connect to any web pages.  Loads were extremely slow.  According to the computer I had a 1 mbps connection.  I did the standard resetting of the modem and router.babble babble babble. Eventually, I ran a wifi analyzer from my phone to determine an ideal channel.  However, while running the frequency scanner I also noticed that my broadcasting would continue to drop off the radar for a quick moment then return.  This seemed to be true no matter what channel I set.  What's interesting is that the signal would read as extremely strong for 45 sec - 1 minute, then completely drop the signal, then another strong broadcast. Other neighboring signals don't exhibit this behavior....well I would see the weaker signals coming in and off the radar from time to time. I'm guessing it's some type of interference?  However if that's the case I can't explain why my signal seems so strong.  I'm assuming I'd see a lot of fluctuation in my signal before dropping off ( instead of going from 100 to 0 in the blink of an eye ).

D-Link DIR-655 :: Internet Status Light Blinks Very Rapidly

May 11, 2013

I have an older rev a DIR-655 that has served me well. Today I finally upgraded my ISP to cable (from a slower DLS connection) to get reasonable speed/price All is working very well but unlike my old DSL modem the internet status light on the DIR-655 blinks very rapidly all the time instead of when traffic is passed.The new modem is a Motorola SB6141,I am running the latest firmware 1.35NA I went through a complete re-setup to see if that would calm the light but no dice there. (the settings arrived at were basically the same for the old Sprint modem) ,Is there something I am missing or is it time to retire the old DIR-655 for something more current.

Cisco Switching/Routing :: Lights On All 3750-X Switches Blinking Rapidly?

Jan 21, 2013

We recently installed 15 of these switches, and we're having a few odd, random network issues. But before I enumerate those issues, I have a simple question: are the connection lights on these switches *supposed* to blink rapidly? Or are they supposed to blink *normally*?On all other switches I've ever seen / worked on / worked around, when a cable is plugged into a port, the connection lights blink upon network activity. sometimes they blink a little faster when there's lots of activity, but mostly it's an almost lazy, random kind of blinking.  When you look at a switch and every light on every port that's connected is blinking very rapidly, your first instinct is "No *wonder* nothing works around here!" and you find the port that's chattering and unplug it...all the blinkies go back to normal.Well, on the 15 switches we've installed, every light that's on blinks rapidly, as if there's an uncontrolled storm going on. Is that the "new norm"? Did I miss the memo, and there is nothing to be worried about here? Or are the rapidly blinking lights telling me there is, indeed, a problem?
