i have a client that uses a draytek 2862n which is located on the ground floor of their premises , they have now taken over the two floors above and would like to extened the WiFi network provided by the router to cover these two additional floors .data cabling is installed to these floors so it is a just a case of installing an access point on each floor .Which would you recommend that are easily manageable and do not require an onsite or cloud controller . we causally use Unify but i find maintaining the controller on an Amazon AWS a bit of a faff when it comes to updating the controller etc .
