I too have same issue of devices getting dropped off frequently. Also the dual band doesnot work properly. The 5GHZ keeps dropping. After lot of chase with technical team they have mentioned they would send a new router .It has been 2 weeks yet not dispatched by AGL. The customer service is pathetic, Speed is ok.I even tried connecting the RJ45 cable to my old laptop directly from router, still it is dropping the laptop.
