Hi All
There are 5GHz interfaces disappearing from our installed AP's (mostly 2700 series). All together approx. 12 AP's in the last 3 months. PoE is not the issue. Country codes are all set correctly. We've tried on several of them to set them to autonomous and then back to lightweight. Also Power-cycle and Reset did not do the trick. It seems as the 5GHz physically is gone. Until now we just replaced the AP's but maybe someone has more input why this keeps happening as I'd like to understand if there was e.g. a bad batch of production or something like that.
Thanks!

No, they disappeared completely. It is as the AP doesn't have any 802.11a interface at all.

AP does not have the 802.11a radio.

We had this issue on 8.0.152.0 as well as on 8.3.133.0, hence it's probably not a bug on the running code.

Probably a bad batch if the radio goes missing. Open a TAC case to either get confirmation that it is a bad batch, a bug or something else. I have seen bugs creep up from older code versions, but Tac would be the only one to confirm if it’s the same or possibly a new bug.
