Cisco Wireless :: AIR-LAP1131AG-C-K9 Radio 802.11b Could Not Be Enabled?
Feb 15, 2012
I've a 2106 WLC and the software is upgrade to 7.0.220.0. There are 3 APs with external power adapter work normally on it. Here is the problem: There is another AP with external power adapter has join the the WLC successfully. But it can not enable the radio 802.11b. Following is the error message on CLI
(Cisco Controller) config>802.11b enable AP001d.a1ef.b5f4 Cisco AP has not enough in-line power to enable radio
I have a Dell Inspiron 8500 Laptop with the Dell Truemobile 1300 WLan mini PCI Card.I have tried uninstalling and re- installing the Driver from the Dell website. I have install Network Stumbler and it keeps saying "No Aps Active.I Have MZC and Dellwirless turned off so that they will not conflict with NS.I have tried the FN + F2 keys and neither worked the FN and other keys work just fine.I have just completed a fresh install of Windows XP Pro as the old OS got corrupted.
I am trying to set up a Wireless network a WLC hosted on an SRE module in a 2911 router. I think i have most of my bases covered but there is still one problem.
My LAP1131AG AP's won't join the controller, on the AP im am seeing this: Translating "CISCO-LWAPP-CONTROLLER.test.local"...domain server (192.168.250.10) [OK]
[Code].....
But to my knowledge an LWAP AP schould be able to join a CAPWAP WLC
WCS is reporting few AP's are not associated with it. While troubleshooting, AP conneceted switch interface shows UP/UP and show power inline output gives IEEE PD instead of AIR-LAP1131AG-E-K, after doing a shut/no shut on AP connected interface. Later after sometime AP comes up.
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.
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.
i have an AIR-LAP1131AG-A-K9 fresh from the box an was trying to register it to vWLC.I have them both on the same VLAN and these logs are showing on my WLC: [code]
The funny thing i have noticed is that both the WLC and the AP cannot PING each other.
we have WLC 4400, we have 40 APs with model no. AIR-LAP1131AG-N-K9 but we recenlty got an AP with model no. AIR-LAP1131AG-E-K9 which is unable to join WLC.
I have a AIR-LAP1131AG-A-K9 this Ap is registered but, i cant enabling admin status on interface B/g, when select option throws a error. "Error in Enabling Admin Status"
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.
I brought a LAP1131AG, only later found out that it can only be used with a controller.Is there any way I could change the firmware to make it a normall Access Point?
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?
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).
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)?
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.
The network consists of 133 RAPs/MAPs/1131 APs and all joined the WLC. When I check the 802.11 a/n radio tab, I see only 129 APs and the 802.11 b/g/n tab I see 133 APs. I found out that 4 LAP1131 is not showing in the 802.11 a/n tab. I tried resetting the AP thru the WLC and still the don't see it in the 802.11 a/n tab.
I've just bought an access point AP1141N for my small business but unfortunately there is only Radio 0- 2.4G available through web interface. It is working fine but I would like to have access to radio 1 (5Ghz) as well.
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.
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".
Im using WLC 2504 with vertion 7.4 and 2600 LAP's the access points are working fine when its isolated from the live network, but once its in the live network the AP radios resetting (APs won't reboot) and unregistering from the WLC in random intervals,
I am building a BOM for a customer and I need to present cheaper options than 3500 or 3600 APs. I thought of these two models but I don't know what models of antennas to pick.1602 is a 3X3 MIMO with 3 antenna connectors. 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.
We have 6 1262 APs and a 2504 WLC. 5 of the 1262 appear correctly with 2 radios. One of them shows 1 radio. See screen shots below showing model numbers and interfaces on the AP with one radio available (All other 1262s show 2 radios as normal). Tried resetting the AP to factory default, but same result. Do I have a defective AP?
I have a 2504 WLC with two 1522 AP's one is Root the other Mesh the 802.11b/g/n/ Admin Status says Up but the Operational Status says down. How can I turn this on? When I change the Admin status to enable I get a "Error in Enabling Admin Status"
When I view web page of 1410 radio is show ethernet enabled and up but radio as disabled and down. I have tried to enable but to no avail. Is this a sign my radio has gone bad?
I have cisco LWAPP 1242 AP already joined controller but 802.11b/g shows down on the radio 0 interface. I tried to enable it but it comes with an error" Error in enabling admin status". I have resetted the AP to factory default settings and even replaced with NEW AP.
I am running the upgrade tool on Aironet AP1230B-A-K9. I can't join the controller by using the upgrade tool. the error is "AP does not have Supported Radio". What radio is the upgrade tool or controller look for on Aironet 1200 series? This AP is running 802.11b. However, I have several APs which the same model is running on the same one controller. The controller is model 4402.
I am facing a problem with my access point AIR-LAP1141N-E-K9, which was converted from LWAPP to autonomous, radio Interface Dot11Radio0 is going to reset down state very frequently.AP is connected to WS-C3560G-24PS (POE) switch. [code]
