Cisco Infrastructure :: Setting Up Two SSIDs On Aironet 1240AG AP
Aug 17, 2011
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.

I have recently purchase Aironet Access Point. I'm pretty new to Cisco systems and what i'm try to do is have the access point broadcast multiple SSIDs lets call them Guest and Admin. My problems is when i config router to have a DHCP address it works perfectly fine but when i assign a static IP it shows all the any connected device as unkown with IP 0.0.0.0. So i'm guessing i will need to setup a dhcp server. Is there a way access point can have its own DHCP server and IP address ( i don't want to use any from my STATIC ip subnet as i dont know alot of empty ones left) like home wifi router where they assign each device an IP like 192.168.0.1. Is this possible?

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.

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).

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.
Sep 29 11:57:14.807 -0500 Warning Packet to client 0c77.1a3a.6ff7 reached max retries, removing the client

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?

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 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 am trying to setup a RV180 and 3 wireless access points. I want the AP's to have 2 ssids that are isolated from each other. IE guest network and main network. I have setup VLAN's and my AP's support 802.1q and have ssid's with matching VID's. I was able to get this to work basically, but things seem to have gotten confusing when I plug the AP's into a POE switch instead of directly into the rv180. At this point I'm not sure exactly waht to ask. Maybe start by providing basic info on how I'm supposed to do this. I was under the impression that since both devices support 802.1q I could configure the VLANs on the router, and tell the AP's to apply a VID to the SSID and thing would work. This isn't the case unfortunately.

I have configured a Aironet 1310 bridge as a WGB and is connected to a Aironet 1242AG AP wirelessly!A sensor(IP device) is wired into the 1310WGB. The sensor needs MULTICAST to operate!I checked the DETAILED STATUS of the RADIO and both the 1310 and 1242 are blocking multicast!The RELIABLE MULTICAST TO WGB option is enabled on the 1242AP already!

We have 2 aironet 1310 aps setup as infrastructure access points between 2 buildings. One went south on us & we placed it. Before the bad one went down, we were able to manage both remotely & could see them from the next device via CDP. Now, we can't connect or even ping either AP. And the weird part is that the switches that connected to each can see each other via CDP, but not the access points between them. I'm attaching the configuration. Before I make the 2.5 hour drive back to the site, what I may have misconfigured on either or both access points?

I've just recently purchased the Aironet 1142n and am hoping to set it up as a repeater. I've followed the documentation here: [UEL] but am still having problems.
What I'm trying to achieve is: I have an adsl router (TP-link W8960N) at the front of the house but the wireless signal does not reach all the way to the end of the house. I am trying to set up the aironet 1142n to act as a repeater and place it in the middle of the house and hopefully that will extend the wireless signal to the end of the house and remove the dead spots. I would like to do this without having ethernet cables running all over the place and have been trying to configure the aironet 1142n to no avail. Every time I set the aironet 1142n to "repeater" it automatically coverts back to "access point" under role of radio network.
I guess my main question first of all is, can I set the aironet 1142n as a wireless repeater? And if so, where am I going wrong in my configuration?
I've just read that " Repeater access points running Cisco IOS software cannot associate to parent access points that that do not run Cisco IOS software."
Does this mean the aironet 1142n set up as a repeater will not work if the original access point (in this case, the TP Link adsl wireless router) isn't a cisco brand?

I am wanting to use a Cisco Aironet 1552EU to use on a site survey for a future deployment and I need to know if it is possible to configure the AP to broadcast an SSID so that my team can search for that SSID and view the signal strength throughout the site. Is a WLC required to set the SSID or is there an SSID that will be broadcast by default that we can try to connect to?

I've recently purchased a 2504 Wireless controller, and I have 10 2600 APs to deploy. I think I've set up the wireless controller OK - there doesn't seem to be much that needs to be done! But I just can't seem to register an AP onto the system.
Just to briefly outline what I have done, I have connected to the Wireless Controller via terminal emulator and run through the setup, then I have connected OK to the web interface, and I am able to view and amend the controller's configuration. So I have setup a WLAN and thats about it.
Next up I have powered on one of my 2600 APs, and I am able to view it working via terminal emulator again. But I am seeing it continually running the same routine to connect to a controller, and all the time it just fails. Below is what I am seeing.
One thing that I am unsure about is that I am unable to connect to the AP config pages via web browser, using the IP 192.168.0.97 (although it does ping okay). Is that odd?
And the main question - why doesn't the AP connect to the wireless controller? Do the APs need to be authroized on the controller first? If I check the controller's web interface, under Monitor - Statistics - AP Join, I can see the AP listed with Status "Not Joined" but I don't know what I need to do to make it join!

I'm working on setting up an Aironet 1040 Wireless Access Point for my company. It's my first time setting up something like this, and I've run into a bit of trouble.
I created my first SSID easily enough, following the manual and guides online. I set up VLAN 1 as my native VLAN and linked it to my SSID with the encryption and security that I was told to use and it works great. However, my boss asked me to set up a second connection as well for guests at the office, and this is where my trouble starts.
I created VLAN 2, and then another SSID which I linked here. I set up encryption and security the same way, and I can see the network when I open up my network and sharing manager. I can connect to the network as well, but I either get a spinning blue icon where my signal strength indicator is or a few bars with a yellow caution sign, and Windows says 'Identifying...'. I've compared the two SSIDs using the console and the GUI and I can't seem to spot any obvious differences between them.

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.

Cisco 1240AG converting to WEP to WPA
Access Point Model: Cisco 1240AG
System Software Filename: c1240-k9w7-tar.123-7.JA5
System Software Version: 12.3(7)JA5
Bootloader Version: 12.3(7)JA1
Access Point Model: Cisco 1131AG
Software: Cisco Aironet Desktop Utility 2.1.02
After converting encryption from WEP to WPA in a Cisco 1240AG in personal mode with an SSID name of example1 and Cisco 1131AG access point in personal mode with an ssid of example2; both with the same wpa passphrase, I created a new profile on the Cisco Aironet Desktop Utility with a new profile name as well as a WPA passphrase, but the desktop utility will only connect to the access point if one network name, example1 or example2, is entered.

I'm looking at creating WLANs using standalone APs for the first time. I know this can all be done with trivially a controller, but this project can't stretch to that...Can I use MAC filtering on standalone APs to restrict which clients associate?I think these will be 1240AG devices but I assume the answer is the same for all models?Can I mix MAC filtering with WEP/WPA? And use MAC filtering without encryption?

how is the IP configuration for this Fast Ethernet F0.
This is because usually we only assign IP to the BVI interface. Is it after that, the Fast Ethernet F0 automatically also be assigned the same IP?
As such, when goto the Fast Ethernet F0 by CLI, by using no shut then this will Enable the Fast Ethernet Port?

I am setting and configure the Cisco AP 1240AG with 5GHz External Antenna extension. The whole product is called iWap. The problem now is that the wireless signal amplitude only can reach 3 bars instaed of ful 5 bars.
Few questions I have for this setup and configuration :
1. What is the default or original frequency of antenna of Cisco AP1240AG? Can a 5GHz antenna work with the AP 1240AG whereby it is run with 802.11a and 802.11g?
2. If 5GHz antenna can work with 802.11a or 802.11g, what is the setting or configuration needed to be done at the Cisco 1240AG? Or, no setting or configuration needed because it will automatically work by default?
