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.
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?
My new e3200 setup just fine with Cisco Connect. I have consistently good speeds with a direct ethernet connection, but the wireless speeds fluctuate widely. When I power cycle the router, I'll have perfect speeds for a few minutes and then it'll slow to a crawl (approx 0.5Mbps). Then for no apparent reason, it will speed back up to normal, and then back down to a crawl. I'm using the latest firmware and have allowed Cisco Connect to manage the router so far.This is actually my 2nd router, as Tech Support told me when I experienced this with the first router that it was defective, but I'm seeing the same problem with the 2nd router, so I know something isn't quite right.
Purchased my dell XPS-17 laptop five days ago. When i connect to Wire less and test my download speed it keeps varying ranging from 1Mbps to 40 Mbps. Where the Wire connecting gives a constant speed of 58-62 Mbps. Checked with my Internet service provider. The analysed the issue, logged into my computer in safe mode and the wireless was giving a speed around 55-60 Mbps consistently. They say some application is causing the speed fluctuation. Can you suggest if any of the Dell Pre installed apps can cause this. I have just installed gtalk/yahoo messenger and Winamp from my side , and they are not in the startup menu and not even launched when i test the speed.
My Belkin F7D4301 Router has the fastest wireless speed of maybe 2MBps but wired with a cat5e cable to my asus laptop of almost 7MBps. I have a one smart TV, one blue ray, one roku, and a nexus 7 using the 2.4 channel.
My Wireless 2.4 settings are channel 11, Extension channel 7, Wireless mode N (have tried with just g and b, g, and n modes), Bandwidth 20/40, Protected mode on, QOS off.
I've talked to Belkin tech support, they are the ones who had me set up my 2.4 channel this way but my wireless speeds stay just under 2MBps, they just want to keep sending me the same model Router because they think each of the new ones they send me is defective.
Am I doing something wrong or is 2MBps the best wireless speed I'm going to get?
I have TL-WR740N router. ISP should provide me up to 100Mb/s internet speed. Actual measurements shows me about 80 Mb/s. The problem is when I enable 3389 port in Port Triggering my internet speed drops to 2,5 Mb/s. When I disable port triggering, speed become normal again.
In our network, we have a 3550 Switch in which the CPU Load is increasing and then decreasing. sometimes it raises to 100%. but there was no traffic during that time.
I have been experiencing fluctuating IP address problems with my pc having windows 7. I've even switched off bonjour and firewalls.In some case it connects to the net but if I disconnect the LAN wire and try to connect to the internet again,I find no connection.
What can be the problem with windows 7,whereas it is fine with my other pc with windows xp in it,thereby indicating that my modem is working fine. MY drivers are also working fine.
my computer is a laptop and its about 3 years old. Ive been experiancing problems with my internet connection...It seems that it is fluctuating between local and internet to just local every 5 minutes or less. Usually I fix problems with my software no problem this time
We have lms 3.2 that we are facing a problem with it. When we start the server the EDS-GCF log file size start to increasing rapidly until it consumes up all free space and it only stops when we stop the Daemon Manager service. I tried to do the pds how command but I get no output from it. I included the portion of the EDS and EDS-GCF log files. i searched and didn't find the cause of this error.
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.
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?
i have an RTA1025W router. When i plug a network cable into it nothing happens. When i power it down with the cable still plugged in when it boots the LAN1 led flashes rapidly then stops? Then no connection to it via the PC?
i have a problem using my usb to serial cable connection, i can connect to one router on my work, but i can't connect to AP 1142, (i have tested also con AP 1231).i have a laptop running windows 7 64 bits, before i use a win xp 32 bits, and i didn't have problems.i am using putty, and have installed tera term 4.74 but the same.connection details, 9600, 8, 1, N, N.
I just converted AP 1142 to LAP using the image "c1140-rcvk9w8-tar.124-21a.JA2.tar".
The WLC is a 5500 with 2 NIC : one on 192.168.0/24, one on a specific vlan 10.20/16 The main management interface is on 192.168/24 but we defined as management the interface on the 10.20/16 network.
For the access points, we use ports on a native VLAN on 10.20/16 with other available VLANS which are used for the wlan networks
We have 1152 APs which work fine on this config but that needed to be registered on the 192.168/24 network, then we moved them in their VLAN 10/20/16 and they work fine.
We also have 1142 APs which have been upgraded to LAP. These AP do not work with our architecture. They register correctly on the 192.168/24 network, but do not give access to the wlan VLANs. If they are moved in the 10.20/16 network, they don't register to the WLC (message : Timed out while waiting for ECHO repsonse from the AP). The AP do not get an IP.
is there a restriction with VALNs on these AP ? or is something false ?
I need to convert some 1142 APs to lightweight mode. They will connect to controllers running 7.3.101.0. I noticed there's two options of Lightweight IOS code available c1140-k9w8-tar.152-2.JA.tar and c1140-rcvk9w8-tar.152-2.JA.tar. Whats the difference between the two versions of code?
When we take a look at the internal antennas on the 1142 AP, we notice the 5ghz pointed all the same way, but for the 2.4ghz we can see each offset by 45/120 degrees. It was my understanding that all antennas are omnidirectionals on the 1142, why are those 2.4ghz antennas not all pointed the same way? onfiguration advantage and that each antenna is indeed omnicadirectional? Example, if I shut just one antenna off, do I lose a sector (120degree)?
I recently purchased another 1142 AP to expand out our current wireless infrastructure, my question is, what exactly needs to be done for this to work so that users can roam freely and auto-connect to the closet AP with the best connection without getting disconnected?
I have set all the settings the exact same on the new AP to match the existing AP. (How to save the configs into a file would be great, I am not sure how to do that)... But anyhow, before I launch it, I would like to be sure I am correct so I do not bring down the existing network. Of course, the only difference between the 2 are the IP addresses. AP1 is 192.168.2.2 and AP2 is 192.168.2.3
The last three new APs I have received from our supplier (official Cisco 1142 LAPs) have all successfully connected to our 4400 series WLCs but are all reporting as being in an Operational Status of 'Down' ie their A/B/G/N radios are not broadcasting even though the APs are all in an enabled state. Furthermore, there is no steady green light showing on the APs - there is no light showing whatsoever (although they were displaying the familiar red-orange-green lights while they were pulling down the IOS images from the WLCs).
The only strange thing I have noticed is that in the AP config screen, the ‘Mini IOS version’ is shown as being v7.3.x. The other – working APs – we have of the 1142 series show v3.x. I know that controller code v7.2 and above only work with the newer 5500 and 7500 series WLCs. Could this be the issue and have any of you seen this issue previously? I am running WLC code v7.0.230.0.
I have WLC 2540 and AP 1142..i have configure them both and got connected(WLC can detect the AP) yesterday then i turn off them both and now when i powered up , the WLC cant detect the AP but AP and WLC can still ping each other they communicated at layer 2, both WLC and AP in one IP segment.

About every 20 minutes 12 of 300 APs keep rebooting. I have tried moving them to different controllers. I have tried downgrading the code and then upgrading the code. I have tried replacing the AP. I have tried swamping out cables. They are all connected to a 3750 stack but plugged into different switches in the stack. Here is the result that I could capture when I saw it disconnect from the controller. This is the output from the AP:
DTLS-5-SEND_ALERT: Send FATAL : Close notify Alert to 10.100.40.212:5246 *Jul 28 14:33:19.595: %WIDS-5-DISABLED: IDS Signature is removed and disabled. *Jul 28 14:33:19.597: %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY *Jul 28 14:33:19.597: %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY *Jul 28 14:33:19.655: %LINK-5-CHANGED: Interface Dot11Radio0, changed state to administratively down [ code].....
I have removed the ip addresses for security reasons.
I have recently been adding a number of installed APs to heatmaps in NCS and am very confused as to the correct Azimuth and Elevation settings.
In particular - if the AP is mounted on a wall rather than a ceiling what should the settings be ( and does it matter - perhaps - as NCS is now dynamic by default rather than the old WCS being predictive perhaps it does ).
Any guide for this covering the following common installation locations.
All referenced when looking at the map view in NCS, front of AP is the side with the Cisco logo and the status LED:-
1. AP ceiling mounted ( Backplate pointing out of map towards your eyes - front of AP pointing down to floor )
2. AP wall mounted ( front of AP pointing upwards towards the top bezel of the screen )
3. AP wall mounted ( front of AP pointing right towards the right bezel of the screen )
4. AP wall mounted ( front of AP pointing down towards bottom bezel of screen )
5. AP wall mounted ( front of AP pointing left towards left bezel of screen )
After some searching I see many people using power injectors or switches that supploy PoE. I am building a lab for the CCNA Wireless and currently have an old Cisco 3550 PoE switch and a 2106 Controller that I got at a steal of a price. My question is, The 1142 can use the 15.4 Inline Power from the 3550 even though it is not the 802.11af standard correct? If it doesn't then I will need to order a power brick.
I have an ipad that is not able to connect to a 1142 Autonomous AP. This AP was originally a light weight AP and then downgraded to autonomous.A strange thing i see is that the AP shows me only two radios. 802.11 N(2.4 GHZ) and 802.11 N(5 GHZ). I suspected the AP not to support the b/g networks. i then downloaded the most recent software but i still cannot get it to connect and on the AP's GUI i only see the above two mentionned radios. i tried to connect to two SSID's. one using WPA2 and another with open authentication and no security.but this does not work. Is it possible that some 1142 do not support b/g networks?
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.
I have some 1142-lap that i have to deploy in my office.
I have successfully deployed 5 out of 8 LAPs . Actually the LAPs was not discovering the controller automatically.
So i had to configure the Controller ip adress through the console in tha AP using the CAPWAP command. Then the AP promptly associates with the controller. Later on i configure the AP name - Primary , Secondary , Tertiary Controllers and everything else and saved it on the controller. This worked out well for the 5 LAPs that i had.
But started facing a peculiar problem with the rest three
As soon as i disconnect the AP from my desk and have it mounted on the celing , to my surprise if find that the LAP doesnt retain its configuration and also doesnt associate with the Controller.
Cant imagine what could be the issue.
I have been told that one CANT wite/save any configuration manually on tha LAP using the console, except by associating it with the controller. Is it a fault with the AP ( as the other APs are working absolutely fine)
