I have a problem my my my wireless module 892W router, I can not leach into the service module by module wlan-ap 0 session have been reset by the wireless module, service module wlan-ap reset default but does not work then I have the router with full reset to default username cisco and password cisco is still the same result here who can give me help me please

[Scott Reu]

What, precisely, happens when you run service-mod wlan-ap 0 reset? What output do you see? Does the command line become unresponsive?

Thanks,

then get the wireless module gerest back, then I try to resume in the leach in to the wireless module by service module wl-ap 0 session but still the same

[Scott Reu]

Can you run the following command for me and paste the output into this post?

service-module wlan-ap 0 status

Thanks,

--Scott

[pcfreak49]

yes no problem, this is the output of service-module wlan-ap 0 status

youname # service-module wlan-ap 0 status

Service Module Cisco WLAN-AP0

Service Module supports session via TTY line 2

Service Module has failed

Service Module reset on error is disabled

Service Module heartbeat-reset is enabled

Service Module Cisco WLAN-AP0

Service Module is in fail open

Service Module status is not available

Thank you for the information. Just one more question--what version of IOS are you running?

[pcfreak49]

Okay the version that is running Version 12.4 (10b) JDA3

[Scott Reu]

Thank you once again. Based on what you've told me (and based on my previous experience with 800-series ISRs), it sounds like your internal AP hardware has failed. I have seen this quite a few times before--the wlan ap can fail in 800-series routers without affecting wired routing functionality, and in these cases, the router will fail to respond to service-mod wlan-ap 0 reset.

I recommend you open a TAC case to RMA the router, as I believe that the internal AP cannot be replaced independently.

Please let me know if you have any additional questions!

Thanks,

You can also concument as a tac case for RMA

I can not try other IOS upgrade to the wireless module

[Scott Reu]

Yes, you can open a TAC case to start an RMA--that's actually how RMAs are supposed be generated. You can either open a case on SCM (https://tools.cisco.com/ServiceRequestTool/scm/mgmt/case) or call TAC at one of their global telephone numbers: http://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html#telephone

Based on my experience, this is unlikely to be caused by a bug or a problem with your version of IOS. These really are classic symptoms of hardware failure on the AP. However, I am aware of a bug (CSCuq33838) that can cause show service-module wlan-ap 0 status to give incorrect results.

The following IOS versions correct this bug:

15.5(0.12.01)GB

15.5(0.16.01)CG

15.5(0.20)PI27a

15.5(0.20.04)CG

15.5(1.02.01a)GB

I can't say for sure whether installing one of those versions on your AP will resolve your issue, but upgrading to one of those versions may help if this bug is, in fact, responsible. Again--to me--this looks very much like a physically failed AP, so if it were my router, I would probably request an RMA, but you can upgrade your IOS version at your own discretion.

Please be advised there is a large amount of difference between 12.4(10b) JDA and 15.5! Depending on how your router is configured, an IOS upgrade may have unintended negative consequences. If you choose to upgrade, then I strongly urge you to check your configured features against the Cisco Feature Tracker tool (http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp) to ensure compatibility with the newer version.

Thank you,

I want to try is a new version to see if the issue has been resolved. But I can not download a new version because I have no contract with Cisco

[Scott Reu]

Unfortunately, without a contract, there's not a lot you will be able to do. I wish you the best of luck getting this resolved! Please post again when you get the wireless back up and running--I really believe it's a hardware problem (I saw this exact same issue almost a hundred times with 881W ISRs in my last job--it's almost always the hardware with those symptoms). But if you put a new image on there and that solves the problem, I definitely want to hear about that!

[pcfreak49]

the problem has come through a full reset of the router from working wireless anymore. At the IOS I have been hit what is the command to upgrade the wireless module

[Scott Reu]

If and only if you are able to session into your wlan-ap, you can do the following steps--the wlan-ap upgrade is initiated from within the wlan-ap session itself.

If you cannot even session into the wlan-ap anymore, then that definitely points to hardware failure, and at that point, you really have no choice but to initiate an RMA.

But if you CAN get into the wlan-ap, then do the following:

First, you'll need to set up a PC or other end device as a TFTP server. Then:

1.  Copy the new AP IOS from your TFTP server to your router;

2.  From the router, enter this configuration command: "tftp flash:IOS.tar"

(The above will make your 892W into a tftp server, and the wlan-ap will then be able to download the file from the 892W).

3.  Session into your AP and issue this command: "archive download-sw tftp://[Router IP Address]/IOS.tar".

I will try the two ways, you know sometimes how much it costs to restore it
