I'm in a test environment trying to understand some statistics. My environment has a single IAP-105 attached to a single vlan network. What I am seeing is many drops on the 5-GHz Radio and I am curious if someone may know what traffic makes up the "Drops" statistics (or what determines a drop). I am attaching 2 files showing the drops for the 2.4 Radio as well as the 5 Radio. My guess is it may possibly have to do with many broadcasts on the wired network, but would think you would also see many drops on the 2.4-GHz too. Or, it may have to do with interference as well. Anyway, I was hoping someone could help explain some of the statistics pertaining to drops. I am running version 188.8.131.52-184.108.40.206_39227.

You should look at the quality of the RF of those channels and also may want to consider enabling dropping Broadcast/Multicast :
- This would let you see if there's a lot PHY/MAC errors
- It would let you know if there's any interfering devices in the area

Let me add a few things. I did have broadcast filtering turned on "ARP" and decided I would collect screen captures with all settings. So, I disabled Broadcast filtering all together and the drops for 2.4 & 5 seemed to track pretty much the same (you can see from 11:20 to 11:30 timeframe). I then used the "all" setting and the drops changed for the 2.4 but not the 5 (you can see from 11:30 to 11:40). I then changed the setting to "ARP" and the drops again changed for the 2.4 but not the 5GHz (you can see from the 11:40 to 11:50 timeframe). So, I am wondering if the broadcast filter is not be utilized on the 5GHz channel and only be used for the 2.4? Any thoughts?
