340 bridge error: "Unable to determine radio type !" How to fix?

I have a BR-340 bridge operating in bridge mode. This is one of the original units shipped right after Cisco took over Aironet but has been upgraded with the latest firmware.

Works fine for several days and then loses association and has blinking red light. The logs say: "Unable to determine radio type !". A reset does not fix this and it must be powered down for a few minutes and re-booted. Then it will work for a few more days.

Can anyone help with a clue here? Is this a hardware problem? Is this unit not compatible with the latest firmware? Does anyone have an old BR-340 image I could reload to this unit to test?

Thanks in advance for any assistance.

If you have a spare power supply, try swapping this as I have seen similar problems when a power supply was on the way out, it is rare though. You can even swap it with the power supply on the non root bridge and see if the symptoms follow

It does not sound like a firmware issue
