an Aironet 1252 which is failing on boot. When power on the access-point shows the error below.
WARNING: A memory error occurred during the system start-up self-test. The device must be serviced if the error persists.
The following commands can, optionally, be used to initialize the flash file system and the TFTP file transfer system:
But when this happen, I can start the IOS manually doing flash_init and boot in ROMMON. After do this commands, the access-point starts and works normally.
How can I check and correct the memory and solve this issue?
I have two Cisco Aironet 1252 that I want to configure as a point-2-point bridge. Now I want to know if this configuration supports the 802.11n protocol.
I am using two Cisco Aironet 1252 (cisco AIR-AP1252AG-A-K9) to setup a point to point link (one is configured as root bridge and is as a non-root bridge). Both Aironets are running software version Version 12.4(25d)JA.
Is there a way that I can that I can perform an antenna alignment test on the Aironet that is configured as a non-root bridge?executing the following command dot11 dot11radio 0 ? does not show the antenna-alignemnet option.
I have 2 cisco Aironet 1252 setup as a point to point link using an external antenna (one radio is setup as the root bridge the other is setup as the non-root bridge). Now I see that the connection between the radios is established at a speed of 54 Mbps. However when I perform a speedtest on the link I see that the my actual download speed does not exceed the 2,5 Mbps. what can cause my actual speed to be far lower than the 54 Mbps? And what can I do to improve it?
Okay, I'm working on a project and the company I work for wants to add 5 Ghz antenna's to their Aironet 1252's. Okay not a problem, except I've never worked with these routers before and I can't get the configuration set (). Once I get 'em on one I can get them all done.
I have two cisco airenet 1252 autonamous access point that are configured as point to point bridge. Now I want to confiure AES encryption or WPA2 using a pre-shared key however I do not see the option to do this . The only option I see under ciphers are:
wep 128 wep 40 TKIP
[Code].....
Is it possible to use either AES or WPA2 using a pre-shared key on the 1252 autonamous access point? preferably using the web interface.
I am trying to poll the 5 minute average CPU utilization of my Cisco Aironet 1252 (IOS version 12.4(25d)JA) using SNMP OID .1.3.6.1.4.1.9.2.1.58.0.However for some reason I am not getting any response back from the aironet. Note I am able to retrive the memory utilization without a problem.
why my AIR-AP1262N-A-K9 will not boot all the way. It will get all the way to initiating the interfaces and stop. I can never get to controlling the cli. This is my first time with a cisco ap but from everything that I read it seamed very easy.
This unit from what I understand will work all on its own with no controller. Hence it is called a "standalone" model. Yet it seems to be looking for something to finish during the boot. Below is the out put during boot. The last line is where it stops.

According to the documentation, I'm supposed to be hitting the Esc key when I see the Loading "flash:/[imagename]" ####### ... line, but this doesn't seem to be working. I've tried hitting the Esc key a lot during those lines, holding it down, hitting it early, hitting it late, hitting it in the middle, and still no joy.
I'm trying to break into a handful of malfunctioning 1242AG APs to see if I can get them working, or if they're faulting hardware that's beyond repair. (So far they're all coming back with: no "IP_ADDR" variable set, so how to set that without breaking out of the boot cycle).
I have installed an Aironet 1130AG and utilized a power injector for the power source. I have the settings configured correctly in IOS, but the AP takes about 7 minutes to come on (illuminate LED status lights) once the Ethernet cable is connected. Is this 7 minute power-on delay normal when using POE? I am used to the instanteous "on" that usually comes with Cisco products being connected directly to the AC adapter.
I'm working on implementing a RADIUS authentication for wireless access with the following :
- PCs running Windows 7, protocol used is PEAP (without validating the server certificate to make it simple at first),
- AP 1252 configured to use a RADIUS server to authenticate (it's working good with an ACS server 4.2),
- ACS Server 5.1.0.44.5 running as VM connected to an AD domain and working good with VPN connections,
- AD domain running on Windows 2003 Server.
My ACS VM is working good since a couple of months for VPN (RADIUS) and administration (TACACS) remote access, both using Active Directory. Now, I'd like to use it to authenticate people connecting to a 1252 Cisco access point but I'm getting this error "24427 Access to Active Directory failed". I switched from PEAP to LEAP but this is the same.

I am an IT professional that is installing my first extended range wireless AP in my companies warehouse. I am very excited!
Now I have set up many a linksys and repeater wireless networks, so when I was looking into the Aironet 1240AG I thought ?No Problem!?
And at first, it is not!
I have the AP and antenna set up here in my office before I take it out and mount it in the warehouse. And I can get connected to it, no security for now, no filters, I just want to connect and make it work.
I stay connected for maybe 3 minutes, I can get to the internet, I can ping all my servers. Full connectivity. But then for no reason the connection fails and I cannot reconnect.
The error I get in the log is
Interface Dot11Radio0, Deauthenticating Station 0006.2510.bbe3 Reason: Previous authentication no longer valid
So strange! So I have reset the AP to factory defaults and then set the SSID, and I can connect, again for a second, then nothing.
I have tried with multiple wireless cards, even laptops. Thinking maybe the problem was on the computer side.
I have just setup a new WLC 2504 controller to manage a WiFi service that will span 6 geographic locations. The local networks at each location are on different subnets (all 192.168.x.x) and are linked up via IPSEC VPN links, and there is Active Directory spanning the sites, with DNS and DHCP servers running at each location.
I tested the WLC at our main office with a single AP, and it worked fine. The AP set itself up, and wireless devices connect with no probs. Great! Yesterday I headed out to one of our remote sites, and connected an AP to their network - and that seemed to work fine too. Within a few minutes I was able to see the WiFi network I'd setup, and my smartphone connected to it straight away (as I'd rpeviously connected at the main office), so I was pretty happy that all was working well.
This morning however I've had notification that wifi performance at the remote site isn't great. I've got someone to check their ip address, and I've found that their IP address and default gateway match the LAN at the main office where the WLC is based - NOT the LAN where the wireless client is. Obvioulsy this is not ideal!
(I guess I HAVE done something wrong!?). And how can I get wireless clients at remote sites to pick up an IP from the DHCP server at THEIR site?
I purchased several 1921 routers and the last two I setup get the following error during bootup:
%SYS-6-READ_BOOTFILE_FAIL: tftp://255.255.255.255/1:aaa1386.bin No usable interfaces. %SYS-6-BOOT_MESSAGES: Messages above this line are from the boot loader. %MAINBOARD_GE-3-SHUTDOWN: FPA PKT pool holding 512 particles.boot of "1:aaa1386. bin" using boot helper "usbflash0:c1900-universalk9-mz.SPA.151-4.M4.bin" failed error returned: No usable interfaces loadprog: error - on file open boot: cannot load "1:aaa1386.bin"
The router moves on and eventually comes up fine and is operational. What this error is an if I can get rid of it?
During the boot ios we found the error messages below. How can i clear this messages?

I have a WLSE Express 1030 which is not booting. The error is "GRUB loading, please wait... Error 17". The error is a mount error for the partition. I don't have a recovery disk and I am not authorised to download the disk.
I recently received these routers and after the first reboot I changed the user id and password so it does not lock out...After configuring my routers for installation, upon bootup I am getting this message scroll down my screen
I have a C3750E-24TD-S on which I just loaded new firmware. When I boot up I see this:Loading "c3750e-universalk9-mz.150-1.SE2.bin"...c3750e-universalk9-mz.150-1.SE2.bin: no such device
I am in the process of updating the software on a Catalyst 3500 series switch. I deleted the old bin file and copied over the new file via xmodem.the image I used is:
c3500xl-c3h2s-mz.120-5.WC17.bin
Once the xmodem copy is complete I performed the following sequence of steps:
File "xmodem:c3500xl-c3h2s-mz.120-5.WC17.bin" successfully copied to "flash:c350 0xl-c3h2s-mz.120-5.WC17.bin" switch: dir flash: Directory of flash:/
[code]....
The last output is where I am stuck. What am I missing?
Every time I delete the directory flash and reinstall it, I get an error:
Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin" Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin" Interrupt within 5 seconds to abort boot process.
That is the message I get. It's set to NO manual boot, but it keeps making me manually boot it. I am at a loss, I've done 3 switches and they all keep doing the same thing.
A new Cisco 3750V2 (WS-C3750V2-48PS-S) running IOS 'c3750-ipbasek9-mz.122-50.SE5.bin' waspurchased to add to a stack of 3 Cisco 3750 (WS- C3750- 48PS-S) switches. The IOS on the stacked switches is 'c3750-ipbase-mz.122-25.SEB4.bin'.I loaded this IOS on to the new Cisco 3750V2 and deleted its original IOS. Boot up failed with error 'hardware not supported by firmware'. I am now trying to follow the recovery procedure but the I can only initialise the flash (flash_init) and there is no 'boot_helper' command to load the boot helper files. There is no option to rum 'copy xmodem' so I cannot upload the original IOS image via xmodem on hyperterminal.
I am replacing an older AP with a new 1252 unit. I attached everything and powered it up, but my DHCP server does not appear to be finding it and assigning an IP address. The status light stays green and the ethernet light blinks randomly green. Seems to be connected fine, but without an IP I cannot configure it to use it.
How can i connect my laptop (11n supported) to LAP 1252 with WLC 7.0.116.0?Status: 11a enabled on wlcDCA channel list in 11a on wlc is showing only 149 153 157 161 channels.
I have a lightweight AP that boots into RoMmon, if i hold the reset button in for 10 seconds or so it will boot into the IOS and download the config from the controller but never registers. then once i reboot it it goes back to Romon unless i hold in the button again.
Is it possible to Change IOS of 1252 LWAP AP to Autonomous AP? I have seen some documents for changing Autonomous AP to LWAP and change back procedures.
we want to have full wireless coverage in a big warehouse (120mx90m) and 15 meter Height that will be having big racks (14 meters height) and 2 meter between the racks and the rack itself is 1.5 meter (2 rack back to back), now we will be having scanners and we need to make sure the wireless is covering everywhere.Where is the best place to put the AP, Ceiling? How Many APs per row ? each row will be around 60 meters length.
Is AP 1252 a good choice? The scanners are a/b/g.What i'm thinking of is to put 1 AP per row mounted on the ceiling and antennas facing down because it is hard to mount the APs between the rack because of the automated racking system.
Currently my company has 1 primary SSID that is used throughout both floors of the building. We have 1252 LAPs which have 2.4 and 5Ghz antennas. I'm not sure if this issue is only with XP or perhaps it's the computer's drivers but we run into problems with end users going to a different location and having a very weak signal or nothing at all, yet coverage is fine. I believe the problem is the end user's machine selecting the strongest signal and it I have the feeling that switching bands isn't being done as it should when it's in range. So my question,
Should I split up our 1 SSID and created multiple SSIDs according to the location and include 5Ghz or 2.4Ghz in the SSID name so it's easier to ensure that users are connected to the proper signal? I want to ask if multiple SSIDs would still enable users to freely roam (as long as the ssids are configured) throughout the building without noticing a loss of signal but currently just having 1 SSID isn't really enabling people to freely roam around without connection issues.I don't believe having multiple SSIDs will be useful for the computer's choose their connection any more efficiently but allowing the user to manually see what they're connected to and pick something better according to their location.
