Cisco Wireless :: AIR-LAP1131AG-E-K9 802.11a Interface Is Down

Jan 26, 2013

I have a WLC 4402 with many APs connected. Most of the APs are LAP1121 and LAP1131 and are working using 802.11b/g. I tried activating 802.11a but for some reason its not working. I see under the Monitor tab that the AP's "802.11a" interface is "down". I have enabled the radio under the "Wireless" tab. Under all the "WLAN" I have enabled all the radios but still not working. 802.11a" interface is still "down".
 
The AP Model is AIR-LAP1131AG-E-K9 meaning "ESTI" regulation. Under "Country" I "checked" IL.

Oct 10, 2010

Since few days the WLC 2100 series controller and 3x LAP1131AG are getting disconnected and the controller gets offline via the local ip address.  At that point I have to reboot. To get anywhere and after I connect wirelessly to the AP before I know it it disconnects.  It worked for 3 years straight no fuss. And now nothing. I reconfigured the WLC 10times and no diffference.

Cisco Wireless :: 2500 WLAN Controller Series Compatible With LAP1131AG?

Apr 17, 2012

I have a customer whom has six LAP1131AG-K9 but no controller and they are interested in one of the new 2500 series, specifically a AIR-CT2504-5-K9 with a 5 AP add-on license to bring total AP capacity to 10.  I can't determine clearly if this controller will work for these older AP's prior to them making the jump to 802.11n via the 3500 or 3600 series, looking to the community to confirm.

Cisco :: Considering And Replacing AIR-LAP1131AG-A-K9 APs

May 20, 2013

We have about 70 AIR-1131AG-A-K9 APs that were installed about 5 years ago.  The controller we use is a 4404 WLC, with software 4.1.171.0.  This provides us our wireless network.  We use Cisco switches as access, distribution, and core switches.
 
We have two guest networks, one for visiting physicians and another for patients and their guests.  Each of these guest networks use a 4402 WLC as an anchor controller, with software 4.1.171.0.  They use the same APs as our business network. 
 
According to my understanding of the guest networks is that a tunnel (I don't know if it is encrypted or or encapsulated) is created between the APs/Guest WLAN to the anchor controllers, so this guest traffic is isolated from our business traffic.  Futhermore, these guest controllers connect directly to our firewall, which only allows them access to the Internet, and not our Internal LAN.
 
Our Problem
=========================
Well, we've been having problems with our wireless system, specifcally with patient guest access.  It has gotten bad enough that they are looking to replace the Cisco APs on the south side of the hospital.  We've been told that "you can get better guest access at McDonalds" : ( .  I think part of our problem is that our controller code is so very old and we are have a our patient guest network open and "restrict" the number of clients attached to it by limiting our DHCP scope.  The biggest complaint we get regarding the patient/guest wireless is people saying "I can't connect to the wireless", which we almost always identify as an issue caused by us running our of DHCP leases (we have about 200).  These DHCP lease are used quickly, by an devices that comes into range that is set to automatically connect to any network that is in range.  A lot of our staff is connected to our patient guest network and don't even realize it.
 
We are interested in Meraki APs because they are magaged using a cloud controller (we won't have the added expense of another controller) and they seem really easy to manage.  Our biggest concern regarding Mearki is security.  They make use of NAT, a Layer 3 firewall, and LAN isolation (a firewall rule that only allows clients Internet access) in each AP as a means of isolating the guest traffic from the business traffic.  Does this seem like a secure way to accomplish this or are the Layer 2 tunnels that Cisco and from what I've been told recently Aruba and Juniper make use of a more secure approach?
 
We've been working with a Meraki vendor, who also happens to sell Aruba and Juniper wireless networks.  It seems like don't suggest Meraki if we are concerned with security.  They said they are good for situations where you have many geographically seperated sites.  They suggested we use Juniper and Aruba, specifically because they use Layer 2 tunnels and that they used technologies like clear air (APs self adjust channels and power, which Meraki claims to do too).  I thought that, hey does Cisco that too, why wouldn't we just go with Cisco if those are your selling points for Juniper and Aruba?

Cisco :: AIR-LAP1131AG-A-K9 / Configuration Is Different On Device Msg

Apr 2, 2012

I have 10 AIR-LAP1131AG-A-K9 connected to a 4402 controller.  I have a couple of questions:
 
- When I go into CONFIGURE/ACCESS POINT, one of the AP's has the message "**Configuration is different on the Device**".  How do I connect directly to the device to check the settings? I tried to telnet but that didn't work.

- Are these access points capable of acting as a DHCP server?  If so, where can I check this setting? I have workstations that are unable to pull an IP address from my DHCP server running on a Windows server. I want to make sure the AP's and/or the controller are not the issue.  The clients see the SSID and the signal is strong, but when they connect they get limited network connectivity message and the IP addr is 169.254.97.123 (which is wrong).

Cisco :: AIR-LAP1131AG - Limited Access When Authenticated

Oct 8, 2011

At one of our locations we are experiencing some problems getting connected to our wireless networks.
 
It is possible to sit right next to an AP (AIR-LAP1131AG) and only have limited access to the network.
 
I have attached a snapshot from inSSID from the wireless networks in the area. All of them are broadcasted by our controller and I can´t figure out how it is possible to see SSIDs in other channels than the ones in the 2.4GHz band (11-14)?

Cisco Wireless :: 250 One AP's B/g/n Radio Is Not Active

Oct 1, 2012

I've recently installed a Cisco 2504 WLAN Controller with (5) AIR-LAP1042N-A-K9 Access Points.  Everything is working fine as far as the APs connecting to the controller, and clients being able to connect to the WiFi and get network access, etc.  The one problem I have is that one AP's b/g/n radio is not active.
 
If I go to the WLAN Controller management web page, and look at the Access Point Summary, it shows that I have five (5) 802.11 a/n radios active but only four (4) 802.11 b/g/n radios active.  I know which AP is affected and clients can indeed connect to that radio using wireless 'B' but not 'N'.I have only one WLAN configured on the 2504 (WLAN ID 1), and one AP group name (default-group) so there are no special groupings of APs.  I have been through every page of the Controller management page with a "fine tooth comb" and cannot find any place where I could accidentally be turning off the a/n radio for a single controller.

Cisco Wireless :: LAP1131 B/g Radio Not Seen In WLC?

Cisco Wireless :: How Radio Works On 7921

Feb 20, 2012

 We have two different entities we support and both are set up as autonomouse wireless groups.  The SSID is the same though so they can use their 7921's between floors and buildings.  The problem we have had is that the phones on the first floor were getting the IP's of the organization on the second floor.  When you view the AP's on the phone the ap directly next to it on the first floor (the one its suppose to talk to) is listed first, The strange thing is that shows it is connected to the right AP (the first floor one). The AP on the second floor is also listed but its about third down.  After the phone sits it will actually change IP's but not all of them.  Their were a few phones that took about a half a day to get the correct IP. 
 
My question is how do these phones grab their ip's?  I know how DHCP works but I am needing to know specifically how the radio works on the 7921's.  What is the boot up process? It appears that it must cycle through each channel starting with the highest and loop through a process in descending order: compare ssid's and then authenticate if possible.  I am assuming it is seeing the second floor first because initially they all get the second floor ip.  The second floor is on channel 60 and the one it should connect to is on channel 36 (We are using 802.11a).  That's how I came up with my descending channel theory.

Disabled Wireless Radio On Westell

Feb 16, 2013

I have a westell DSL modem/router supplied by Frontier. It connects only to the telephone line and via cat5 to my main router, a cisco EA6500. Everything seems to be working fine, I just would like to understand a few things.I disabled wireless radio on the westell, enabled it on the cisco, so I have just one WIFI network active.I know I am not supposed to have two DHCP servers active, but I did not know how else to be sure the CISCO would get a good address, so I left DHCP active on the WESTELL, and also enabled it on the CISCO to provide service for the rest of the net.The WESTELL admin interface is at 192.168.1.1, and assigns addresses in this range.According to the WESTELL, the CISCO is at 192.168.1.27, which I assume was assigned by DHCP.The CISCO has an admin interface at 10.144.224.224, and assigns addresses in this range to all the other devices on my net.As I say, everything works.I can access both router admin pages with a browser on my main 10.144.224 network, and can ping both.But I don't understand why it works.What rules allow me to talk to the WESTELL admin page from the CISCO private network, but do NOT propagate the DHCP access which is at the exact same IP address.

It is great that it works. But should I really have disabled DHCP on the WESTELL and assigned a static address to the CISCO? Or is this situation actually provided for in the rules, not just a lucky accident that it works?Why does the scanner say that the CISCO DHCP is "Unknown" rather than Authorized or Unauthorized? Is there something I can or should do to get it to be "Authorized"? I can ping 192.168.1.1, but not the 192.168.1.27 (times out), and yet when I ping a non-existent 192.169.1.3 I get "Reply from 192.168.1.27: Destination host unreachable".

How many 2.4 GHz and how many 5.8 GHz antennas should I pick for each radio?2602 is a 3X4 MIMO with 4 antenna connectors. In this case I suppose there are 2 connectors per radio.
