Cisco Wireless :: WLC 2100 And LAP1131AG Are Disconnecting

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 :: 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.

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

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  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  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 Wireless :: WLC 2100 Configured To Control Two AP

May 17, 2012

I have a fairly simple WLC 2100 configured to control two APs. We had a power outage a few days ago, and though the WLC was on a surge protector, it did not come back up properly after the outage. The STATUS light sticks at amber and I can't get any console response. At this point I'm not sure what to do except replace the WLC, though I'm loathed to do that as our budget was just cut substantially for next year and we're trying to turn nickels into pennies.

Cisco :: Setting Up Wireless LAN Controller 2100?

Feb 7, 2011

I am having trouble on setting up a WLC2100 ver 7. we need to implement a private and public network. private network authenticate to IAS - RADIUS (windows server 2003 server) while the public network is open but when a client connect to AP it will redirect to a 3rd party web athentication - HotSpot Server. the challenge is we want to broadcast a single SSID.

1. when a user/guest connect to the AP a radius server will authenticate thru IAS - Radius.

2. when a user is authenticate via radius a dhcp server will give an ip address of the private network.

3. if the user is not authenticate a dhcp server will give the public ip address and netowrk traffic must go to a different VLAN.
my question is, is it possible to broadcast a single SSID for the two network? is there a document which is related to our scenario?

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 (which is wrong).

Cisco Wireless :: WLC 2100 Per-user Bandwidth Contracts

I got screen captures of WLC QoS Profiles options, with Average Data Rate in Per-User Bandwidth Contracts. So my question is, do I need any other equipment to achieve per user bandwidth limitation? Can it be done with WLC QoS options?

Cisco Wireless :: WLC 2100 Ipv6 Ready Connection

Apr 30, 2012

We have a 2100 cisco Wireless LAN Controller which manages 3 APs and  assign IP address to clients which connects via wifi.  Currently, we are  deploying dual stack IPv6 and our consultant stated that our current  controller does not support IPv6.
This is rather odd statement because there is an option to enable IPv6  in the advance tab of WLAN.  And sometimes clients (win7 and Mac OS X)  are getting v6 addresses, able to ping v6 sites, and reach v6 sites  successfully.   And other times, clients do not..or getting the v6  address for 10-15minutes, then unable to ping/reach v6 sites.
Our consultant is sticking by his words saying it does not support.   If  this is true, then clients should not be able to get v6 at all....not  sometimes and not other times; very inconsistent.
And what is ipv6 pass through? What is ipv6 bridging?

Cisco :: 2100 / Two Network Connections And One Wireless Controller?

Jan 29, 2013

In the near future my company is looking into the option of adding a second network connection (exclusively for customers visiting our facility) to our pre existing WLAN network. We are currently using a Cisco 2100 series Wireless LAN Controller and probably 6-8 APs. Our main connection is made up of 4 T1 lines and the second connection will more than likely be a cheap DSL connection. I'm wondering if this technology supports two separate connections on one controller and APs. For example, is there a way within the controller web interface to separate what is currently our "Guest" connection from the main Internet line? I was thinking of just plugging from the DSL router directly to the controller and save the hassle of changing routing and VLANs.

Cisco :: AIR-LAP1131AG - Limited Access When Authenticated

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 :: Configuring Trunking And VLANs On A 2100 Series Wireless Controller?

Oct 4, 2011

We have 4 1142N LAPs that I want to divide between an internal wireless and a guest wireless network using the controller.  Currently all of the APs are on an established internal network, but I want to migrate one over to a test guest network before buying more LAPs to augment the networks further. Currently the port connecting to the WCS from the 3560 switch is configured as an access port using VLAN 10.  Whenever I make it a trunk port carrying VLAN 10 as well as the other ports we will be using for the guest and ap-manager networks, I lose connection with the controller.  To me this implies that the port on the controller is configured as an access port as well.  In the documentation I found for the controller it states that by default the ports are al configured to be trunks, but it appears as though something was changed by the previous tech.  All of the APs are connected to other switches, not to the controller itself.
1) How can I get the port on the controller back to being a trunk port

2) Can I use the internal DHCP server for the guest network if the subnet is different than the management subnet, or will I have to use another external server and relay/proxy it through the controller to give guest clients IP addresses?
