Cisco :: Aironet 1240AG Is Not Broadcasting SSID For MAC
Jan 31, 2012
I have a "standart" settings of Cisco Aironet 1240AG with ENABLED broadcasting SSID, encryption is WPA2 (AES). I can see the wifi network (ssid) with windows system but with MAC OS 10.5 and MAC OS 10.7 also with iPhone the wifi is acting like hidden. But If I manually enter the wifi ssid and set the proper encryption the connection work normally. Also I have a separete windows partition on one MACbook and this windows 7 have no problem to see the SSID of my network. But If i Boot to the MAC OS the WIFI is "hidden" until the manually connection. (same problem on iphone, manuall connect with manually entered SSID is working well).
I configured the device manually, not even using Express Setup or Express Security setup so... it is possible I missed something.Anyway, here's the problem. Although the SSID is configured as "AP1", this SSID does not appear among available networks on the client laptop.
The connection, configured in Group Policy for the client, should actually happen automatically, based on the SSID, but since the SSID is not being broadcast, that connection is failing as well.
The Aironet does appear among the available networks as "Other Network" and if I click on "connect" I am prompted to enter the SSID -> AP1
Although, unexplicably, an error message displays (Windows cannot connect to the network, or something to that effect), the laptop *does* connect once I close that window. Network access is complete and functional - I can ping other hosts, etc..
I'd post screenshots but not knowing what setting is missing or incorrect, I'd have to print dozens. So here's the sh run output of the AP obtained via telnet (just below). This is a test network so all information is "real" (nothing changed for privacy):
Note: I even changed the hostname to "AP1" (it's still LAB1 below) but that did not resolve the problem (did not think it would).
We have Cisco Aironet 1240AG Wireless AP's in out network. Now, we have some PC's, laptops and mobile phones connected with with this AP and all devices are working fine. Now suddenly from today when I am trying to associate some new devices to the AP it is not working means the devices are not associating.
For 2 year now we have been running aironet 1240ag access points throught our warehouse. We use a telnet session on our handheld scanners to connect to our database on the main server.This last week our scanners started getting dropped from the access points serveral times throught the day and often would continue to get dropped at 1 minute intervals for several minutes at a time. This appears to be happening on all of our access points and is affecting all of our scanners but not at the same time.Each time a clinet is dropped we get the following event log on the AP.

All the AP's are setup the same with the below config

I have a Aironet 1240AG and have our main SSID set up on Radio0-802.11G. It uses WPA TKIP. Everything works fine on it. Recently we have been getting a lot of visitors who need wireless access, so reather than hand out our main key to visitors, I decided to create another SSID on Radio1-802.11A for guests. For some reason the new SSID does not show up on the available networks on client devices. You can connect to it manually by entering the name and key. But how do I get the SSID to broadcast on the 2nd SSID. A lot of these guests are not very computer smart, so it becomes a real pain to have to walk them through connecting to the guest network.
We are using an Aironet 1240AG series wireless AP here to connect handheld scanners. They work fine on WPA. However, when we switch to WPA2, they often lose connection. We have tested on 802.11g and a bands, with various encryption types (TKIP, AES, TKIP/AES). Also, how can I update the outdated firmware without signing up for a service contract?
I work as Network administrator in a building products plant at Poland. We had core switch HP Procurve 6200yl with 5 vlans, and 11 Aironet 1240AG Access points without controller. I have a problem with create 2 wi-fi VLANs on the Cisco AP's and linked it with HP switch.
VLANs on the switch: 1 - Default (for office sutff) - working great, 2 - Production (for production stuff) - working great, 3 - Inter (for Router's) - working great, 4 - WMS - i need configure it as wireless, 5 - WiFi with Radius - i need configure it as wireless.VLANS on the Access Points: 4 - WMS - for warehouse terminals - WPA2, 5 - WiFi for office stuff with Radius.
I'm easily able to get it running a single SSID (non-VLAN) network and confirm that I can use that network fine. However, I need to set up these 2 VLANs. I can connect to it via telnet if that'll let me program it faster.
I am an IT professional that is installing my first extended range wireless AP in my companies warehouse. I am very excited!
Now I have set up many a linksys and repeater wireless networks, so when I was looking into the Aironet 1240AG I thought ?No Problem!?
And at first, it is not!
I have the AP and antenna set up here in my office before I take it out and mount it in the warehouse. And I can get connected to it, no security for now, no filters, I just want to connect and make it work.
I stay connected for maybe 3 minutes, I can get to the internet, I can ping all my servers. Full connectivity. But then for no reason the connection fails and I cannot reconnect.
The error I get in the log is
Interface Dot11Radio0, Deauthenticating Station 0006.2510.bbe3 Reason: Previous authentication no longer valid
So strange! So I have reset the AP to factory defaults and then set the SSID, and I can connect, again for a second, then nothing.
I have tried with multiple wireless cards, even laptops. Thinking maybe the problem was on the computer side.
I have a Cisco Aironet 1240AG Access Point and I am trying to setup a guest network that is secure and limited in bandwidth utilization. I see an option under security > SSID Manager on the web interface to select an interface of Radio0-802.11G, Radio1-802.11A or both. Can I put the guest network on the Radio1-802.11A and make it more secure/bandwidth limited or does this option not matter?
Several days ago I had to change my router. The new one works OK except that I can't get the PC to link into the wireless while the SSID isn't being broadcast. Having read that it is a good idea not to broadcast the SSID for security reasons, I thought I would try it!
I am running Windows 7 home Premium and the router is a Draytek Vigor 2710 using WPA2. I can see the network when the SSID isn't being broadcast, it just refuses to connect to it. As soon as I switch on the SSID it connects like a dream.
i have 2 DIR 615 routers which both stop broadcasting SSIDS. Ive had only one connected at a time, thinking it was a bad router, but both behave the same way. Is this a known issue or something ? What happens is, after some time (it varies..sometimes 3hours..sometimes longer), the router stops broadcasting the ssid, and I can no longer connect any of my wireless devices to it. The hardwired connection does work (I have a server connected to it, and it appears to work).The only settings I have changed is my SSID name, and wpa2 password. I've set up one virtual server to port forward requests to the server. Thats it. Nothing complex or anything. And both routers behave the exact same way, meaing they stop broadcasting the SSID.
I have a Cisco 5500 Series Wireless LAN Controller Model No. AIR-CT5508-K9
I have HREAP groups in Boulder, CO, Boston, MA, and Amsterdam, NL.
The LWAPPS act perfectly in the states (all AIR-LAP1142N-A-K9). The unit AIR-LAP1142N-E-K9 in Amsterdam will not allow any clients to attach unless the SSID broadcasting. I don't want to broadcast SSID. I have used iPhones and Intel 5100 series wlan cards. I don't get it. I have been working with Cisco for weeks. We have even replaced the LWAPP.
I am getting this from the ASA in Amsterdam:
6 Aug 03 2011 20:20:22 PMTU-D packet 1485 bytes greater than effective mtu 1426, dest_addr=wificontroller, src_addr=LWAP, prot=UDP
I don't understand because the mtu on the outside interface is 1500 I guess "effective" is the key word which I missing here.
I have an Aironet 1042 wireless AP if I create an SSID with no security it shows up as wireless N when I see it on a windows 7 laptop. As soon as I apply any security settings is shows up as G and not N. I just want to be able to authenticate with a Windows 2008 server running NPS - this works fine but I obviously want to connect at N speed and not G.
We've had a Cisco 881W set up in one of our remote offices for a while and the wireless has been fine. Yesterday I got a call saying that the wireless was no longer working.
I went over and it's true, the SSID is no longer broadcasting. I reloaded the router but it's still the same. I tried to get access to the embedded ap and I get this
RTR#service-module wlan-ap 0 session % telnet connections not permitted from this terminal RTR#
Now I've not changed anything on the configuration since it went in and it was working before. Has the embedded ap died? The embedded ap is still showing as a component in show hardware.
I am running the demo of the virtual WLC and have one 1142N AP connected to it. I have two WLAN's created and they are configured to broadcast their SSID's. However, when I look on my laptop or Android, I cannot see either of them. I checked the AP to see if it has the WLAN's on it and it does. I did this by going to Wireless -> Access Points -> Radios -> 802.11a/n AP Interfaces -> Details. Under Station Configuration Parameters -> Number of WLAN's, there are 2, which is correct. I had this demo running on VMware workstation and had some bridging issues with it and thought that was the issue. I now have it running on ESX5.1 and am still having this issue. I am at a loss as to what is causing this problem.
I have Build a 5508-HA Cluster (7.4.100.0) , hat to reboot this cluster due to Licens install.After the reboot atleast one of the SSIDs was not broadcasting anymore, even the checkbox was checked.
What did I do:
Installed the Licenses @ Freiday 12:00 @17:15 reload active WLC, wait till controller is up again (a few minutes pingable) @17:25 force failover to first controller. check a few SSIDs but not all, those who where check are ok. @monday 07:00 clients complaining not seeing the SSID (some where connected)
I have several Aironet 1231 APs most running 12.3(8)JEA software. There are 4 SSIDs on (each in separate VLAN), with only one broadcasting (called pubwifi). The broadcasting one is an open, unencrypted network: [code] After adding another braodcasting SSID (encrypted, separate VLAN), I encountered weird situation: my WiFi clients are unable to connect to pubwifi. It is not showing in the available networks or is showing as an "unknow" network. New encrypted/bradcasting ssid is advertaising just fine.
I have a linksys WRT54G that has been bugging out a lot. It stops broadcasting the SSID briefly and won't start again until it reboots. Annoying enough problem on it's own, but not my primary concern.My concern now is that when I tried to upgrade the firmware to the latest version (which I presume was causing the problems) the router now is essentiallyunresponsive. The upgrade was successful according to the control panel site, but ever since the required reboot as part of the upgrade process the router hasn't worked properly. 1) The power light blinks constantly rather than staying lit.2) When I plug directly into it sometimes I get access to local networks and other times I don't (limited connectivity). But I never get access to the internet if it's plugged into it as well.3) When I try to go to the control panel site (through the 192.168.1.1) the site wont loadGranted this router is old, but it was working fine other than dropping the broadcast every once in a while. It did need a firmware upgrade, but the upgrade seems to have been a bad choice
SSID is not being broadcast from an e3200. I split the wireless networks and assigned a new name for the 5Ghz band. The broadcast SSID button is enabled for both networks. (2.4 & 5). The idea is I want to stream video on the 5Ghz band. Nothing seems to see it though, TV other PCs, etc.
I changed the 5 GHZ SSID name using Cisco connect on my E3200 router as was expecting to see 2 available wireless networks on my laptop, but it seems that only the 2.4 GHZ is still broadcasting as it was before. When I connect to it with my laptop it shows it connecting with 802.11n, so I would think that my laptop would see the 5 GHz SSID if it was broadcasting. I am trying to take advantage of the dual band feature and connect the 5 GHZ to my blue ray player for real time video streaming.
So I have this E1500 Router that worked fine for the past 5 months, then out of the blue, the wireless feature ceased to function... laptops were not being able to connect to the wireless, the router was also not broadcasting the SSID.So, here's what I have done so far:
1. Check the router software settings, all was good there.
2. Did a "hardware reset" pushing the red button. (now this solved the problem, BUT only for a day, when power is turned off for the night, the next day it's non-functional again. The cycle can be repeated daily, but its a pain to reset and set it up everyday)
3. Updated the Firmware, and this somehow solved the problem for 3 Days... and now it's back to non-functional, again out of the Blue.
Is the Router just busted and it's not remembering the settings?
I am working on setting up a new WLAN infrastructure. I have set up different SSIDs connected to different VLANs, in the AP. I also want to use Windows NPS for authenticating users on the different SSIDs, with different authentication methods based on which SSID the user/device is connecting to. To do that, NPS needs to get the SSID, but the Aironet 1240 only sends its MAC address in the Called-Station-Id. I have read a bit about this, and found out that if I have a WLC, it will add the SSID to to the Called-Station-Id. But since we do not have a WLC, I am trying to get this to work anyway. Is it possible to modify the Called-Station-Id to include the SSID on an Aironet 1240? If not, is it possible to send the SSID as a separate attribute that can be read by the NPS?
I wonder if there is a way to rename an existing SSID on aironet 1142 without destroying/recreating. I tried downloading configuration/ changing name/ re-uploading however that didn't have desired effect. There doesn't seem to be a way via web-GUI.
We have three Access Points, two Cisco Aironet 1260 and one 1240AG. Originally, the SSID was hidden on all three AP's and users had to go to Other Networks and type in the SSID and password to access the WAN. About a few months ago, the network started broadcasting to the public. I am trying to make the SSID hidden again. I have tried going to the Security tab, choosing the SSID Manager and setting single guest mode to none but it has not worked.
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.
I have configure my AP with to SSID (11 & 12), but I cannot connect to 12. It authenticates, and while trying to acquire IP address from 12, it fails and connects me to 11 (if I have already saved the SSID connection).
The following is my AP status:Product/Model Number:AIR-AP1231G-A-K9 System Software Filename:c1200-k9w7-tar.123-8.JEE System Software Version:12.3(8)JEE Bootloader Version:12.3(2)JA4
The SSID 12 already have 4 clients connected, And I am tring to connect a 5th one (smart phone), but cannot connect to 12, instead coneected to 11. Also tried with a laptop, but cant get the IP address, and give Limited Connectivity error.
We have multiple Cisco Aironet 1131AG devices, all wired on one Cisco L2 switch(2560) who is connected to L3 switch (3550). We assigned one VLAN for access point in L3 switch who acts as vtp server (L2 switch is vtp client). All ap's will have static ip address and all will have same SSID and no security and they will be using multiple channels (ex. 1,6,11). They will operate in 3 floor building for roaming wireless client. We won't using any wireless controller.
How to configure APs-all the same with different ip's, can we use L3 switch to create dhcp server for access points VLAN (pool for clients, and the rest for static ip for ap's)?
i've been looking for a way to isolate clients on a Cisco Aironet 1121 on a certain SSID, and i cant find anything, tried pretty much everything i coudl remember, but since im no expert on Cisco wireless.
