i have my main deco m4 connected wired to my tplink router ac1200 and the second deco is connected wirelessly with the main. the deco is set to AP mode. i have a 300Mbps unifi plan. usually it can get 300Mbps but sometimes, it suddenly capped to 100Mbps. only happens sometimes. then i have to reboot the main and satellite deco together , then after it can get to 300Mbps back. it happens to be annoying as i need to reboot everytime it happens. can someone help me?
