Cisco Wireless :: AP1262N AN Radio Configuration (autonomous)
Mar 26, 2012
Recently installed a 1262N AP in autonomous mode. Have both 2.4 and 5Ghz radios running- Both on separate SSID and VLAN. I think I have 5Ghz channels using 40Mhz bands (bonded) but when I do iperf throughput test I only get about 25Mb throughput. I am sitting within 10 feet of the AP. When I switch to 2.4 I get around 60Mb and that's not bonded. I have tried multiple interfaces on my client side laptop I'm testing with since I thought maybe it was a quirky card or driver but I get same results. Am I doing something wrong here? My laptop shows a 300Mb connection to 5Ghz and 144Mb on 2.4Ghz but I know that's not true thorughput so that's why I was testing this to see what I was really getting and now I'm confused.
This is one of our first site where we are implementing Cisco wireless, and we bought some external Autonomous AP1262, when we should have bought Lightweight LAP1262 . We can get those replaced, but I am looking into migrating them in order to get them to register with our 5508 controllers.
There do not seem to be a migration tool to download for 1262. Must it be done via the WCS ?So far I have not managed to add these autonomous AP to the controllers. How to know if a migration toll exists for those !
we have a couple of AP1262N-E-K9 access point with firmware version 12.4(25d)JA1 operating in autonmous mode.
I attempted to measure the signal quality between the APs by setting one device to repeater mode while all others are in root mode. Then, I execute the following command: dot11 Dot11Radio 0 antenna-alignment
1. The output of "show dot11 antenna-alignment" is incorrect, the % value represents the signal strength in dBm without the - (minus). E.g. "-25 dBm" is displayed as "Signal 25% 0 dBm".Now, I know that is only a display error but still this is not clean. Is this a known issue?
2. Why are the measured signal strength values not displayed on the SSH console during the antenna-alignment test? Is it obligatory to use the console to see these values? Or is it also a known bug which might be fixed in later firmware versions?
we have a couple of AP1262N-E-K9 APs with firmware version 12.4(25d)JA1 operating in autonmous mode. One AP is setup as repeater while all others are in root mode.
The repeater has setup one parent MAC address so it associates every time to the same parent root AP. Given this setting, I am logging into the repeater via SSH and start the antenna-alignment scan: "dot11 dot11Radio 0 antenna-alignment timeout 4"
During this scan, the repeater disconnects from its parent to perform the scan so no output is visible at the SSH console. After the scan is finished, the repeater re-associates to its parent and some output appears on the SSH console.
8 of 10 times this procedure works fine: the scan is finished and I can continue entering commands on the SSH console. However, in some cases the repeater is not reachable any more for about 7 minutes. I.e. pings to the repeater's IP address are unsuccessful and the SSH connection hangs until it is automatically disconnected after a timeout. Also, the web configuration interface is not reachable. After about 7 minutes everything works fine.
I converted a Cisco Aironet 1142 Lightweight access point to Autonomous and at first it works properly but every some days the dot11Radio0 interface is down (similar case than the cisco support community case "Autonomous 1142 AP shuts down 2.4 radio interface"
The 802.11g radio shows as “Dot11Radio0 is reset, line protocol is down” while the 802.11a radio appears to be up and running,
I have to reload the device so that the Dot11Radio0 is up again,
We have a couple of autonomous 1262's that I'd like to get configured. I would like to put the Ethernet interface out on our Internet subnet and have the clients get a RFC 1918 address from the radio's. Our little Linksys is setup this way and the clients are PAT'ing off the Ethernet interface when they go to the Internet.
Is this possible with these guys or do I have to put the AP ethernet interface into the same subnet with the DHCP scope? I don't have enough Internet IP's to hand out to every wireless client.
I have a wireless install using several standalone 1142 Access Points. Yes, I know it would be better to use a WLC, but there isn't one and no funds to install one, so I have to work with what's there...
I'd like to configure the 1142's for wireless N connectivity. Yes, I know I need to ensure WPA/PSK is the security used as WPA/AES, the default option in the CLI won't be happy with wireless N.Currently I am running them in B/G only and they work just fine with WPA/AES. No issues are reported by the users, but of course I'd like to get them running N for the increased throughput so I need to kniow the CLI steps required.
My current setup is an AP1262n located ~400 feet from my WAP321. I would like to take the wireless signal coming from the AP1262n and rebroadcast it using a WAP321. configuration setting on these two devices.
I can't seem to get the SSID RadiusTest to work properly.
Windows PC's show "Windows was unable to find a certificate to log you into the network". Macs don't authenticate either. Radius server isn't seeing any requests at all. Radius server is working because we are authenticating other things to it.
On my test 1231, IOS is 12.3(8) JEB1.

we have a couple of AP1262N-E-K9 APs with firmware version 12.4(25d)JA1 operating in autonmous mode. One AP is setup as repeater while all others are in root mode. My goal is to perform the antenna-alignment test through an SSH console on the repeater with a given timeout-value, e.g.:
"dot11 dot11Radio 0 antenna-alignment timeout 4"
However, the behavior of this command is inconsistent as the timeout value is ignored in 20% of the tests. I.e. in 80% of all tests, the scan really runs only 4 s as specified using the "timeout" parameter. In the other 20% of the tests, the "timeout" parameter seems to be ignored: Often the antenna-alignment scan runs for about 140 seconds and in some cases even for 420 seconds. This is problematic as the access point is completely unavailable during the test, i.e. the configuration ssh/web interfaces are not reachable and no clients can associate to the access point. [URL]
is it possible to manage a air-ap1262n with a controller like wlc 5500 or wlc 2500? the official cisco support could not answer me this question for sure. i have found this old guide to upgrade ap´s to lap´s, but there is hothing about the 1260 in it. [URL]
i am a little bit confused!
the cisco documents tells: "at_a_glance_c45-636090.pdf"
A wireless network with standalone access points offers a low-cost, entry-level solution that does not require a controller. It is ideal for small-scale networks with less than 20 access points, and offers base-level wireless functionality with the flexibility to scale and add services over time by adding a controller.
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 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'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]
Running vwlc 7.3.101 and encountered a smaller issue.When you enable / disable a SSID, all AP's reset their radio interfaces... causing everyone to drop their connection.
Not sure if it's new in WLC 7.4 code, but I now see "Dual-band radio" section everywhere in addition to "802.11a/n" and "802.11b/g/n". My dual band APs (for example 2600's) show up under both 802.11a/n and 802.11b/g/n as in the past. So what is this new category "dual-band radio" for then?
We are using the CISCO-DOT11-ASSOCIATION-MIB in a Cisco Air AP 1140 device with release 12/4(21a)JA1 to find out the radio type of wireless client (B/G or N). The clients in question are of type Wireless N and Wireless B/G. We are querying cDot11ClientDevType and cDot11ClientRadioType but the relation between the returned values and client/radio type is not clear:
2 devices returned: cDot11ClientDevType = 102 ==> pc4500Client(102) - client with a 4500 radio and ClientRadioType=2==> ccxClient(2) - CCX- compatible radio1 device returned: cDot11ClientDevType = 1==> unknown (1) – unknown and ClientRadioType= 1==> unknown(1)
Questions: On a Cisco Air AP 1140 device
What OID needs to be polled to find if the client's radio type?What value is returned by this OID if the radio type is B/G?What value is returned by this OID if the radio type is N?
