Ho Eklund, Since most of your customers are using Mac OS , its a client with both A/n and G/N radio . Try to do few things : 1. Use Radio Preference group ( under AP window there is Load group , create few groups - e.g one per floor let say) . It will push muximum number of people to use cleaner A/N 2. Disable DCS , or put it in monitor mode. 3. On 2.4 Radio choose G/N instead of B/G/N , unless you know of having B-only clients. 4. You can try to enable MPDU aggregation on both radios.
33 clients per AP is not a big number.
