Hello folks,
I have deployed at a customer site an 851 wireless router. After the config was ready in the evening and all was alright with the wireless clients I have left. Next day morning the router had this problem (in the attach). The SSID was not broadcasting and on the lan, the DHCP was not working, on the console port was running screens with these output. After a restart it was ok, but I've removed him from the network. What could be the problem?
Thanks,

Hi guys,
I'm back at the customer site and the IOS was c850-advsecurityk9-mz.124-4.T7 but today i've change it with c850-advsecurityk9-mz.124-15.T5 and after the reload on console appeared this:
flashfs[5]: found corrupted block[66] (byte 0, sector 0), fixing...

I will associate just 2 pc's with the router to see if the error repeat. Here are 5-6 ap in range, and I think maybe are some interferences.
Thanks,

Hi,
can you try with the command :
verify flash:c850-advsecurityk9-mz.124-15.T5
Does the command show flashfs works and clear flashfs works ?
I feel you may have to format the flash again and reupload the ios image ?
The downloaded image will have some checksum information on cisco. If the verify command fails you need to match the checksum and md5 with the ios downloaded and the md5 and checksum from cisco.

Seems like HW fault and you should RMA the unit.

Thank you guys,
I have left the router in test for a couple of days, because i'll be gone in a business trip.
