APO01#

Dear all,

I have a wireless network with autonomous AP. That works with WPA2 and Certificates.

All the other Ap works well, but there is one that sometimes drops all the client.

The configuration is identical to the others, but I got the error above and a dump file is written in the flash:

APO01#dir flash

%Error opening flash:/flash (No such file or directory)

APO01#dir flash:

Directory of flash:/

Do you have any ideas?

Re: %DOT11-2-RADIO_FAILED: Interface Dot11Radio0

Thank you for your reply.

Yes I will try ti update the IOS.

But I think that it doesn't fix the problem, because I have others idenditical AP with the same IOS, and It doesn't have any problem...

Before you upgrade the IOS, can I ask if you can attach a console cable and reboot the WAP?  Post the entire bootup process.

%DOT11-2-RADIO_FAILED: Interface Dot11Radio0

I can not attach the console cable, the WAP is at 6 meters from the floor.

But I have made the IOS upgrade to c1250-k9w7-tar.124-25d.JA1. Now I am waiting to see if the problem is fixed

Hi Leo,

after the IOS upgrade, everything works well.

Best regards,

It looks like this is a 1250 series....correct?

If so you may want to try reseating the Dot11radio0 module that it is complaining about as well.

%DOT11-2-RADIO_FAILED: Interface Dot11Radio0

Yes it is 1250.

Before to do the IOS upgrade I have tryed to shut and anable the Dot11radio0 and I got a dump written in the Flash.

Now with the new IOS, it do not happen.
