Cisco Wireless :: Connecting 1552 LAP With 802.11a Using AIR-CB21AG-E-K9
May 27, 2012
I'm having a small issue using my external CIsco Wireless Card AIR-CB21-AG-E-K9 with a Lightweight Access Point 1552 (Outdoor) using 802.11a Radio.
Description of issue :
I can connect to a wireless network when i set the Wireless Mode to 2.4GHz 54 Mbps (802.11 g), and 2.4 GHz 11 Mbps (802.11 b) on the card but not with 5GHz 54 Mbps (802.11a).
Note that this card is compatible to 802.11 a, b and g.
All settings on the 2504 WLC is set to default regarding the radios configuration.
Both radio interfaces type (802.11 b/g/n and 802.11a/n) are operational and Admin status Enable on the WLC.
The status of the wireless card is as follows :
Profile Name - Wifi-Test
Link Status - Not associated

I need to update from older Cisco 350 Aironet 802.11a/b Wireless CardBus Adapters to Cisco cb21ag Aironet 802.11a/b/g Wireless CardBus Adapters in rugged tablet pc's. I need these without the antenna cap present to utilize the tablets antenna sytem. They are pictured on the Cisco website but Cisco partners I've contacted have been unable to assist me in purchasing them.

I haven't been able to find any Windows 7 compatible drivers anywhere for the CB21AG card and there seems to be nothing on the Cisco site. These drivers required, when they might be released?

I am able to view clients, rogue APs, rogue clients etc, but the information is faily inaccurate. Thus, I am trying to calibrate using the RF calibration models. I have created a new model and am attempting to add data points.After adding the client MAC, selecting the floor plan and clicking next, the floor plan loads and a message pops up stating: "Could not enable S60 across all relevant controllers on this floor". I click OK, and select "point" as the calibration method. When I place the calibration point on the map and click GO I am presented with the following message: "Failed to initiate data collection. Please make sure your client is connected on the wireless network and then try again." Both of these messages can be seen in the attached screenshots.
I have confirmed that the client is associated to an AP located on the map.I have confirmed connectivity of the client.I have used both the Cisco AIR-CB21AG-W-K9 (CCX V5) and the integrated intel wireless card (CCX V4).I am running WCS 7.0.172.0, MSE 7.0.201.204, and WLC 7.0.116.0.

I am testing a Cisco 1552 and cannot seem to set it to use the 40 MHz channels. In the controller GUI is is set to use 40 MHz channels under DCA for 802.11a but when I go into the CLI and show the config of the AP it shows the channel width to be 20 MHz. If I try to change the channel width through the CLI I get "radio is not disable or ap not set to customize" or something like that. The radio is disabled globally and locally. Is there a way to set the AP or radio to a "customize" mode?
What prompted this was I was testing the throughput on it and can only get a 130 mbps data rate connection to it. The data sheet says it will support 300 mbps with the 40 mhz channel so I was trying to test it atteh higher rate.The HW is a Cisco 4402 with 7.0.230 software on it, 1552E.

I have configured a 1552, that is wired to network, as "Bridge" then "RootAP".
After reboot, I can see a MAP trying to join the network, in the "simple" logs of the controller :
"Mon May 6 17:29:43 2013 Mesh Node '04:da:d2:1f:4d:6f' failed to join controller, MAC address not in MAC filter list."
As I have done for the RAP, I enter this MAC address in the MAC Filtering area under Security tab. But this action doesn't solve the problem, I continue to see this message in the controller logs !
If I open a SSH session on the RAP, I can see this block of debug messages repeat all the time :
*May 6 15:29:33.163: %MESH-6-ADJ_VIDB_LINK: Mesh neighbor 04da.d21f.4d6f VIDB Virtual-Dot11Radio0 dot1x control
*May 6 15:29:33.167: %LINK-6-UPDOWN: Interface Virtual-Dot11Radio0, changed state to up
*May 6 15:29:34.167: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Dot11Radio0, changed state to up
*May 6 15:29:43.223: %MESH-6-LINK_UPDOWN: Mesh station 04da.d21f.4d6f link Down
*May 6 15:29:43.423: %MESH-6-ADJ_VIDB_LINK: Mesh neighbor 04da.d21f.4d6f VIDB Virtual-Dot11Radio0 going
When I take a look into detailled debug messages of the controller I can see this :
*spamReceiveTask: May 06 17:30:44.364: #LWAPP-6-RADIUS_AUTHORIZATION: spam_radius.c:242 The system could not send join reply, AP authorization failed; AP:04:da:d2:1f:4d:6f
I don't know why the system talks about dot1x or Radius Authorization, and if this is the source of my problems. On a other hand, I can see in the debug messages that there is a 2 hours lag time between controller (correct time) and RAP (incorrect, I suppose it synchronize with the controller?)

I'm trying to become famillar with Cisco Mesh AP's deployment. As I know RAP's (Roof-top AP's are AP's with Ethernet/Fiber connection to the network). I connected these AP's via L2 switch , they can reach WLC and everything looks fine.
No I want to connect few MAP's to my RAP's. But of course firstly we will need to set-up IP addresses for these MAP's? But how? There is no "configure terminal" option at all ( on mesh AP console) .
MeshAP#?
Exec commands:
access-profile Apply user-profile to interface

Client has existing 1522 outdoor access points over different branches.1522 is dicontinued and 1552 is the replacement AP.Client intends to extend their outdoor wireless with the new AP's.Are there any known issues if the 1552 is mixed with 1522 envi?,Is a separate controller required for the new AP's?Will MESH work between 1522 and 1552 AP's?

a customer got an 1552 outdoor AP in local mode and installed it at a building. It has to run as a Mesh AP (MAP). Now the AP connects one time to the WLC 5508 and started a download. After that, the AP never came back. Like we saw on the other installed 1552 RAP's, they all where in local mode.We configured all AP's to bridge mode, but the MAP could not join anymore.Is there a CLI command to change the mode on the AP itself?From the WLC it's not a problem, but for the AP CLI I cannot find sth.

I found this sentence in 1552 AP guide."AP1552 comes only in the Bridge mode and the mode cannot be changed. A mesh access point performs CleanAir function and also serves clients on the assigned channel similar to the way the Cisco Indoor CleanAir AP3500 (nonmesh mode) operating in LMAP mode serving clients on its assigned channel. The mesh AP also monitors the spectrum only on that channel."We want to use this AP as a local AP ( not for mesh deployments) and serve our wireless clients. The main thing why we need this is just operating temperature. Is it good choice? Does it will function as "normal" local AP or we will have any problems , because of that "mesh" mode?

I need to know if i can connect RAP to RAP and maintain redundancy with connection to WLC.
I have one 1552 with the gigabit ethernet connected to the gigabit ethernet to another device that has a point-to-point link with another device where have a ethernet connection with a switch in the same broadcast domain where i have my WLC.
Next to this 1552 i have another 1552 that have the same situation, both with omnidirectional antenna.
I would like to have a Mesh connection with these two 1552 in 5Ghz, because if some point-to-point link is down i need redundancy to the WLC and my network, because i have some clients connected in the 2.4 Ghz in both Access Points.

Couple questions on setting channels on Cisco 1552s. First off almost all locations are fibered and set as RAPs. It doesn't allow me to set the channel assignment method to "global" to use DCA. It says it can't be done for a mesh backhaul AP. Is there any way around this? Next, when the channel is set to "custom" there are only 5 channels listed to choose from in the UNII-3 band. The spec sheet on the 1552 shows it supports other frequencies in the UNII-2 and UNII-2 extended range. Why can't I select those channels?

I want to set up AP 1552 as outdoor access point so serve clients. This AP is connected to 3750X switch and recieving power over ethernet.Now, by default AP 1552 come with bridge mode and it cannot be changed to local mode. I read on one of the post and made it ROOTAP but still the OPER STATUS is down. This device is already registered to my WLC.
what needs to be done to bring the AP in operational status.[code]

I have to install a wireless mesh network shortly using Cisco 1552 APs. This will be controller based using 5508 controllers. The controllers currently have some 1262 APs configured in a mesh and bridging configuration so happy that it all basically works. My question is - what is the "config mesh range' command doing on the controller ( or setting the Range(RootAP to MeshAP) setting on the controller mesh GUI. The default setting is 12000feet and I have left it at default at present. Just interested in what this is used for - I assume it alters the mesh protocol parameters somehow ( or the RF parameters perhaps ) as it suggests in the guide that mesh APs will reboot following this command being changed.

Child MAP failover to another parent MAP takes 4 request time out (rto). Client applications also time out and needs to reconnect everytime it happens. It is a normal behavior for a 1552 ap?

I'm deploying a Cisco Mesh infrastructure using WLC 7.2 version and 1552 APs.
This Mesh APs will be connected in the Light Pole and the RAP will be connected to the SP Switch located in this same Pole.
The MAP will be powered using Pole source power and will be connected to the RAP over 5.8 Bach haul.
My Customer asks if is possible that in case of SP Switch lost the connectivity to the Backbone IP, the RAP can connected to another RAP and maintain the connectivity to the Backbone over the Air, like REPEATER FALLBACK mode in Autonomous version.
For that I thinking to change the role of the RAP APs to "MAP with UTP Cable", but I'm not sure that a MAP AP with CAPWAP tunnel over UTP Cable can provide a Down link Backhand to another MAPs. That is possible?

We are having a hard time to console into to the APs using the serial connection (USB to serial converter).We have tried the recommended settings (9600, 8 bits, no parity, 1 stop bit, no flow control (also tried XON/XOFF)) without any success.We are able to connect to 3560 series switches and 5508 WLCs using the same cables, notebook and application (putty, hyperterminal & secureCRT).

I know that a 1552 AP has 4 Ethernet ports. Is it possible to use them as some standard switch ports? If I connect two ore more devices to these ports do i have connectivity between them?

I connect to my corporate network using Cisco AnyConnect Secure Mobility Client. Once connected I can no longer print to my LAN attached printer and other local resources. I use the Cisco/Lyncsys E4200 router on my LAN and can re-connect to the storage on the local LAN by setting up Port Forwarding of port 21 and MS Windows FTP folder sharing. However, I can't seem to connect to a Terminal Services client by forwarding port 3389. Is there a way to connect to the local LAN after logging into the VPN connection. I can connect to regular HTTP/HTTPS sites and most other type of connectiins, just not my own local resources.

I believe I know the answer to this question already but I just wanted to make sure. Is it possible to connect a LAP access point directly to WCS without using a WLC? WCS is just for management and reporting and does not act as a WLC.

We just moved, and the family room (where the desktop is) had no coaxial outlet. The exterior box is at the other side of the house, and instead of wiring around our entire home, cable guy said we could easily set it up where the previous owners did (living room), and use a Netgear USB to make the desktop wireless.At Best Buy, I was told to buy Netgear N600 Wireless Dual Band USB Adapter WNDA3100 for $50. I install with the cd, and then plug in the USB as it suggests, and it just blinks from yellow to blue, not picking up my netgear wireless router in the other room. I go back to Best Buy, and they say that I need to buy another thing, now it's Netgear XET1001 85 Mbps Wall-Plugged Ethernet Adapter for another $70.Plugged one unit into the wall, and then plugged it into the Netgear Wireless Router. This will give me a solid light for Power LED and Ethernet LED, and then the middle, Powerline LED is a solid blue. With the second adapter, I plugged that in to my family room (with the desktop) and attached it also to my desktop with it's cord. This one has a solid light for the Power and Ethernet LED, but for the Powerline LED it's off. So it's not finding the other compatiable key, if I put it in between the wireless router, and my desktop (in the hall or kitchen) it will have all lights on, but I can't connect it with the cord to the desktop, and the USB does not pick it up any point.
Now, I can connect with my phone to the wireless network anywhere in my house, including the second floor. However, I can not, with or without the wireless adapters, connect with my laptop to the wireless network. I've done wireless with my laptop since I purchased it a few years ago, and while it can "see" the network, when I try to connect I get an error message that it's unable to join the network, and is now out of range, even when I'm sitting right in front of my modem/wireless router. It doesn't prompt for the password, I tried to manually add the password under network properties but it did the same error.I just don't know what to do or to try next, I don't know if I've set it up wrong, I followed the pictures in the manual, which is all it pretty much comes with, and did all the installation disks. Without it though I can't connect with my laptop, but my phones can..

I have had troubles connecting my PS3 to my Orange livebox. At first, I had the problem that it could not obtain the IP address so I manually entered it. This solved the problem. However, I also manually entered the Subnet Mask, Default Router (Gateway), Primary DNS and Secondary DNS. Now when connecting, it says I have a DNS error.(80710102)

I recently purchased a E1550 that works fine until I tried adding an external USB HDD for storage. The drive is a Western Digital 500MB drive I used to use for backups. Had no issues setting up the share and was able to access it just fine. But a few hours after hooking it up, my wireless devices could no longer connect and I could not access the admin page to see what was wrong. The E1550 was still pingable and my wired devices could still access sites through the router. Cycling power to the router did not work. What did get things working again was removing the USB drive (which killed all wired connections as well) and then cycling power. The E1550 was fine after that.

Having a bit of a strange issue with our Access Point at the moment. I recently set up a WAP4410N as our main WiFi hotspot using WPA2 encryption and it seemed to be working fine for all users, We had no issues when connecting Windows 7 laptops or windows phone 7 phones.However, we have a few people in our office that use HTC desire phones and while the phone will connect to the network it will not allow the user to browse the web or access any internet enabled features on their phone.The more puzzling thing is that a user with a HTC wildfire phone is able to connect to the hotspot without issue meaning it can't be a general Android issue.

I'm in the process of trying to get a used LAP1142N access point connected to my already established WLAN. We currently have 7 active LAP1142N, our controller is a AIR-WLC2112-K9, and I am only trying to add one additional access point. I say this access point is used because we purchased it used, given it's not out of the box and hasn't ever been active in my environment. So far what I've tried is initially connecting the access point on to my network (powered over Ethernet) and consoled in from my desktop. With this, I was able to see the previous configuration so I ran a write erase/ reload. The AP shows a solid green light, but doesn't receive any configuration from the controller even when plugged directly in to the controller (on ports 7 and 8). I'm new to wireless, but familiar with Cisco CLI and web interfaces. I can't necessarily tell if this AP is set to autonomous as opposed to lightweight, but that could be the problem. Otherwise I'm lost. I've attached text files with the boot from CLI and show run from CLI.Let me know any additional information you may need. End note, I'm recieving DHCP (you can tell from boot), but it's not the same subnet as my controller or other active access points.

I need to configure 3 Cisco Aironet 1131g for use. Normally we use the Cisco Aeronet 802 and once these are connected onto the switch, I can log on the WLC, find them and change the name and other settings. For some reason I cannot see the Cisco 113g on any of the WLC.

I am moving to a house in a fairly remote part of Australia without a telephone connection. To get the phone connected will be very expensive and take considerable time. I have mobile phone and wireless internet connection available but only with the most expensive provider. I am not a big user of the phone but every now and then, I have to make one of those calls that go through adozen menus and then leave you on hold for an hour, theb type of call that can send you bankrupt using a mobile service. My proposed solution is to have a prepaid wireless internet account, using a USB dongle connected to my computer as the internet connection. Then to connect either a SPA3102 or a PAP 2T between the computer and a handset and use a VOIP service such as Voipcheap to make calls. With this setup, I would have unlimited landline calls within Australia for around $50 per year, much less that something like Skype. Can I do this and if so, how? I have both devices and they are both presently configured to work connected to my Linksys gateway. Do I connect the computer to the LAN or eithernet of the SPA 3102 and will it just require a normal LAN cable? How do I assign the various addresses required? Do I need any extra software for my computer?
