Command to enable "Service module reset on error" - Cisco 881WG

[mark.davisson]

I am trying to use the 881WG in a vehicle (patiently waiting for a "hardened" version to do the same) and it appears the wlan-ap service module is hanging - possibly due to vibration, software bug, other?

The only way to recover is to reset the service module. When this is done, the AP rejoins the WLC controller until it gets back into the "failed" state.

My question is:

• Would enabling "reset on error" possibly help with recovery when the service-module goes into "failed" state? Does anyone know how to enable this in IOS?
  
• Is anyone aware of any issues with C880 15.1(1)T2 that may be causing this?
  
• Are there any debugging options on the service-module or the Wlan-GigabitEthernet0 interface that would be useful to gather more information?
  

Many thanks,

Mark

I have this same problem.  The wlan-ap0 will just not stay running.  I sometimes have to reset it 3-5 times before it will come back on line.  It will run for between 15 minutes and an hour or so, then shutdown again.  I have about 25 wifi hosts and about 15 wired hosts on the lan side of the router.

anyone know how to get the 881w wlan-ap0 service module to STAY out of failed state?

I have an 881W and in the service-module for the AP the Dot11Radio0 interface is stuck at Reset.  I have repeatedly entered 'no shutdown' to the interface and saved but it never shows up in the config.  I have done factory resets.  I would like to upgrade the ios image for the AP module but need a contract.  Any ideas bringing the interface up?  Hmm... maybe the ios image is in the nvram and I could reinstall it, erasing any corruption??
