Hi there, This is an interesting suggestion. We do use MAC filtering, but we have a list of MAC addresses in each case. The random connection drop-outs still continue d: we thought the MAC filtering would help block lo cal crack attempt w hich we could see going on into the n ight, when n o one was in the building... Then at some point Cisco released a Firmware update (early 2014?) that added a partial software reset following certain software errors - but this was a patch that clear ly didn't res olve the underlying issue. Eventually, it would drop out again, and need a co mplete reboot.
We eventually had to move all of our Public traffic to a different access point with a more user-friendly LAN isolation - then the problem stopped. It seems that the WAP4410 is fine as long as it's only connected to good-'ol laptop wifi cards - if you add in an assortment of contemporary smartphones, then it eventually crashes.
I've stopped buying Cisco equipment after this experience. - petrac001
