I don't know why this happens after 10 STAs for you, but iwlwifi/mvm supports at most 16 STAs, as far as I can see. So you better look after a card which can actually handle 80 devices. Please note that having a NIC which can connect 80 devices and having a nicely working setup with 80 devices transmitting concurrently are two different things. If a large amount of your devices are transmitting concurrently, I'd advise you to use multiple APs tuned to different channels, each handling a much lower amount of clients. Maybe 20 - 30. If your setup works after using multiple APs also depends on the external interference in the environment. Furthermore I would advise you to use 5 GHz channels if possible (I know Intel NICs don't support 5 GHz in AP mode).
