Cisco WAN :: Signal Strength Of Aironet 1140
Apr 11, 2011
In our project we are building a smartphone application dat determines the locations of persons in a building, using Wifi access points.Using 3 accespoint we are calculating the overlap of 3 circles.Today we measured the signal strength and found out that it changes around alot.So we dont really know if our measurements are right.
We would like to know what the RSSI strengths are of the following access point per meter.Cisco Aironet 1140 2.4 ghz

I've set up a Cisco Aironet 1301 AP to be used for a guest network. I've got several other of the Aironet 1140-series around the business but none of them are in reach of this one at the moment.
The problem I have is that clients that try to connect to the AP are either not able to connect at all or lose their connection after some seconds. The config is more or less copied from the other APs with the same guest VLAN.

I just installed an Aironet 1140 to replace a Netgear ProSafe access point that I had in my network prior. I'm having one issue that I can't figure out though. None of the client PCs can establish a connection to an external (over the internet) VPN server while on the Aironet wireless. If i unplug the AP and plug a PC into the same port that normall feeds the Aironet I can VPN just fine.
Is there any "VPN Passthrough" option that needs to be enabled somewhere on the 1140 that is blocking this traffic for some reason?
i'm running the following IOS BOOTLDR: C1140 Boot Loader (C1140-BOOT-M) Version 12.4(18a)JA3, RELEASE SOFTWARE (fc1) and I've included my running config below

If I do a speed test (bandwidthplace.com) while connected to a remote locations 1140 standalone access point, the download/upload speeds are roughly 100kbps. There are no other devices connected to the access point at the time. Wired PCs on the LAN that the access point is connected to are not having a problem.Pings from the laptop, through the access point, to our central WAN router are at <10ms.The WAN circuit (remote location to headquarters) is 5Mbps. No congestion.Circuit out from headquarters to I'net is 50Mbps. No congestion.Access point and router interfaces show no errors or collisions, etc. The configuration is the same as 28 other standalone access points in 28 different LANs on the WAN. They have no problems.

I have an Aironet 1140 AP that will not connect to the network when on PoE (either using a Cisco PoE injector) or a Avocent Switch that provides PoE.
The AP will boot up and and devices will connect to it (the LED changes to blue) but none of the devices can get access to the corporate network or internet. When the AP is powered by the standard power supply, it operates normally, i.e. devices can access the network. Are there settings that can be changed to get the AP to work correctly on PoE?

I am using a Aironet 1100 series access point (AIR-AP1142N-N-K9) with IOS version c1140-k9w7-tar.124-21a.JA1. I want to create two seperate SSID's on the access point with WEP encryption. There is no VLAN configured and i want it to be like it. Also I need to broadcast both the SSID's at the same time, so the some of my users need to login with the first SSID and the others to login through the other.

We have been successfully using our Aironet 1140 AP in standalone mode with mainly Windows pcs & laptop users, and now, iPads and iPhones. All seem to connect happily through the 1140.
Recently we have a requirent to be able to use Apple's Airplay. Basically, it is not working through the 1140, it works ok via wired ethernet. Can the 1140 support Airplay? - If yes, what precisely must be enabled/configured?
We have a single Class C network without any Vlans. I understand multicast must be enabled, I can't see where to enable this. How to get this working if it is at all possible.

Just a few days ago, one of my coworkers computer was unable to see any of our wireless access points - all aironet 1140. He is one of two using a Win 7 machine, everybody else uses Mac with either Lion or Mountain Lion. The Macs can "see" and connect to our wireless AP's just fine.
The odd thing is that is his computer can pick up our neighbors wireless access points, but can't "see" ours. Also, a few peoples phones can no longer detect them either - both iphone 4's (ios 5.1.1 and 6) and androids (2.3 and 4)
No changes were made to our AP's, then people started having wifi issues.

The command that is given returns an error at the letter a in archive. The command I used was: archive download-sw /overwrite /reload tftp:// obviously with my tftp server info and file name at the end. I logged in with privileged EXEC mode as directed, but archive is not listed when I type ? to get a list of commands. I need to have this AP up and running by Monday.

For some time now I have been looking for a good business class wireless AP. I've narrowed it down to the Cisco Aironet 1140 standalone (no controller). I'm no stranger to Cisco products. I've worked with their routers, switches and Pix/ASA firewalls. However, I've not had the opportunity to work with their wireless AP's. Anyone using these AP's (more specifically the 1140 standalone), can provide information on the reliability and security of these devices. Some of the features I would like to have like Radio Mgmt. and Rogue AP Detection I see are only available on the controller based units. Does not having these features on the standalone unit reduce its reliability and security? This is for a small business and the budget does not allow to drop for a controller at this time.

I am having an issue with my Android Tablet running 4.1 (Jelly Bean). It is able to the SSID, but when I try to connect - it stays connecting and then says saved, and never connects, as it does not pick up an IP address. I updated the firmware on the Aironet 1140 due to my Windows 8 pc's not connecting as well, it solved my Windows 8 problem, just not my Android Tablet problem. My Ipads do work. Just any android device I connect.

I've got an AIR-AP1142N-E-K9 access point, i've got the Radio0-802.11n(2.4ghz) enabled and the 5.0ghz disabled.
i've got my client real close to the AP and i only get a connection speed of 72Mbs.
Shouldn't i get 150mbs? Maybe some wrong configuration?

I recently changed the configuration of my Aironet 1140 from WEP to WAP2-Enterprise to make it more secure. I am using the WAP as the radius server. After making the change I connected my Blackberry to the wap as well as a Samsung Chromebook. However when I tried to connect my HP laptop it is unable to connect. Watching from the Aironet's console I see that it is processing the association and windows ask me to enter my uid and password. When I do this I get an authentication error. I have tried several times adjusting parameters on windows but it always fails. Here is the configuration of the WAP:
!
version 12.4
no service pad
service timestamps debug datetime msec
service timestamps log datetime msec
service password-encryption

I am in the process of installing an Aironet 1140 standalone AP. I have not worked with these AP's before. I will be connecting it to one of the PoE ports on the existing ASA 5505. My goal is to have 2 SSID's, one for internal network and one for guest internet only, no access to internal LAN. I want to have the internal wifi clients and the guest clients on seperate IP networks. The internal clients obtain DHCP from the existing server and use the ASA DHCP server for the guest clients. And of course, I would like the ability to manage the AP from the internal network. I am providing copies of my current configs for both the ASA and Aironet.

I bought 2 Cisco 1140 series Access Points a couple of months ago. We would like to use PEAP to autheticate with Microsoft IAS Radius Server & Active directory. I cannot find a document which describes how to setup this type of configuration. The only document which is close is how to setup LEAP & with ACS: [URL] I initially followed the 'TechReplublic's Ultimate Guide to Enterprise Wireless LAN Security' which has all the steps to setup Radius server, client side configuration, Certificates and finally a handy excel script to generate a config for the AP. This did not work. [URL] I am now trying to configure the AP using the Web GUI. I can see the network on the client machine but when I try to connect it timesout.

Users are facing issue since a long time now . Whenever user connected to wireless is idle say 10 -20 seconds he gets disconnected This happens for all the users and even Mac/Win 7 I changed Activity Timeout on AP and even rebooted but still when I do show dot11 associations all-client I see activity-timeout
Users don't get disconnected when there is continous flow of data its only when user is idle
When user disconnects and hit refersh it starts working again

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.

I just installed 2 new units and neither will connect to a new HP gigabit switch - no link light, other devices can connect to the switch OK. Their gigabit ethernet settings are set to auto for duplex and speed. I also tried forcing one of them to full duplex and 1000 Mbps which didn't work either. They're both powered by POE injectors. If I connect them to a 10/100 switch they work fine.

Our office has 4 Cisco Aironet 1140 access points mounted on the ceiling. They are all powered via PoE. Every few days 3 of the 4 access points hang and have to be rebooted. When they hang I am not able to connect to their web interface to check the logs. The fourth, for some reason, always seems to stay alive.
I checked the configuration for all AP's and "Hot Standby" is disabled They are all using static IP addresses. I've tried 2 different banks of static IP addresses and 3 of 4 still hange so I don't think this is an IP conflict. I have saved the configurations and compared them and they are all identical, where possible.
They all have software version: 12.4(21a)JA1
They all have bootloader version: 12.4(23c)JA1
I have tried to download the latest software/firmware, but unfortunately I do not have a valid service contract in place with Cisco and therefore can't download the latest version. All of our CISCO hardware was purchased from Amazon resellers but no luck. I have also tried to contact Cisco and they can't seem to assist either. How I can get a valid service contract that information would also be very useful!!!
why 3 of our 4 access points would hang? When they hang, I can't login to the web interface and the logs seem to reset when I reset each access point. I have also set up an rsyslog server and I don't see a log entry that would indicate a problem.

Is there a way to view my exact signal strength(say in % I guess) with my laptop running windows 7?I had software for the wireless card in my tower pc which gave a signal strength of 70%. I'm curious if my laptop is getting a similar strength since they are close but a few feet apart. Or where in my house gets the best signal other than just showing low-excellent.

I have purchased two WAP200 units to act as access point and repeater. AP and repeater functionality works fine.
The issue I am having is extremely poor signal from both units. Even when very close to the WAP200, I get poor signal quality. The range before loosing connection is only a few feet.
I'm using the antennas that came with the box and have tried multiple placements both in my house and in other locations. I have also tried changing several of the configurations without any effect on the signal strength. Older D-link and Linksys routers provide good reception to most of my house from the same location.

I have two AIR-AP350 SERIES AP's. I am receiveing wifi from my friends house a mile away across a valley with clear line of sight. I think there is a problem with one of these units because when doing a link test one unit shows 14% signal strength on either antenna from the remote router and the second unit shows 6% on the left hand antenna and 1% on the right.

We just recently invested in 5 RV180Ws to serve as replacements for the aging routers in 5 of our shops. Additionally, we bought them because they seem to offer robust WiFi options for customers/guests, such as multiple SSIDs and restricting 'public' traffic to it's own VLAN.
Straight out of the box we updated them to the new firmware, 1.0.2.6, set up 2 SSIDs (one hidden for employee use, and one broadcast for customer use), and plugged them in.
Everything seemed to be going great until we walked to the other side of the shop and watched the signal drop off almost completely. These are fairly small premises and the router can't be more than 8 metres from where the customers are, and yet the signal is so weak that it's almost unusable.
For reference, we have the WiFi running in B/G/N mixed mode to maximise compatibility. with the channel and width set to their defaults (Auto and 20MHz, I believe).
Moving the routers is only semi-viable; these are meant to serve as replacements for existing IT equipment, and the cabling situation means they can only really go in the office space near the rear of the shops. Also, it simply shouldn't be necessary; WiFi should extend well past 8 metres without issue.

I have three desktops and one lap. I have TWC RCA modem and cisco linksys router and two usb adapters for wireless connection. situation is this: the modem and router are at one end of the house and one of the pc's is located at the other end. that one gets low signal strength only one or two bars and the internet works slowly to a point it feels like i'm on dial up. I've had people tell me to upgrade the router from wrt45g to n which I did to an e1000, but I still have the same issue. also was told to move the modem and router to the center of the house. but twc says that would not correct the issue.
Something about dividing the mpbs and the farther the pc the lower the signal. so, guess my question would be 1. does that sound correct to you. would it be better to move the modem and router? would it be better to have the one in question wired in? I did try an extender by netgear, which gave more bars/signal strength but but then would not connect to the internet. but I did that before I got newer linksys router. not sure if maybe I should try the extender again, but then the geek squad, when they came an set up the new router, said that it would probably do the same thing.

I have computers scattered across our home, and in many areas it is not feasible to run ethernet cable. At one location (less than 30 feet away) but through multiple walls, I can barely connect to any POS (I have two). I added a stand alone antenna extension with long antennas on both the router and the WiFi card on the PC, however, this made zero improvement.What should I be looking to purchase to increase the signal strength? I've already tried different routers.
