Hello,
I have a cisco 857w ISR router. My wireless access point was working good until yesterday. Suddenly the wireless light is gone & there is no interface in the router named dot11. I could not even get into the interface configuration mode of dot11radio 0. sh controllers command doesn't show the dot11 interface as well. Is my wireless module is damaged ? Is there any process of recovery ?
Thanks

Is my wireless module is damaged ?
Possibly.
Try rebooting and post the entire bootup process.

Unless you have smart net on that device, there is nothing you can do except get a new wireless router.

If you want to get the same model, check e-bay or Cisco Refurbished Equipment.
If you want something better, look for 887W or 897W.
