dot11radio is missing

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

what to do now ? repairing or replacing ?

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.
