anyone know how to check for port availability for unifi? wanted to subscribe to unifi, Maxis or Unifi fiber better? my location is pandan perdana, perdana villa PV3, Jalan Perdana 2/1, 55300 KL

currently i rented a room, and my house already have maxis fiber, but due to the constant upload data, my game experience has been horrible with the ping fluctuation between 14ms ping to 1000ms ping.

I've been thinking about setting up QoS to improve my condition, but Maxis Fiber router provided does not have QoS function(i know it has it via Telnet configuration), but account and router belongs to landlord. so i think i should avoid screwing up his router.
