Question about QoS? Simple network here; a couple of 2.4G devices (already been mentioned by using Legacy since they began dropping after switching to this RT-AX3000 router), a couple of 5G devices, no Mesh, no gaming, no USB drive and no longer using internal VPN but DO have Cake enabled since it is now built-in. I decided to upgrade my ancient cable modem that has a max 100meg speed limit to a new MB8611 and switch to Xfinity's 900meg service. Speeds are great measuring from the router then decided to disable QoS. Settings got applied then within minutes, noticed my (2) 2.4G devices (thermostat and weather station) began dropping/reconnecting every few minutes. and saw my RAM usage went from 48% to 60%. Ok, perhaps the router needed a reboot. Did that but continued drops/high RAM use. Re-enabled QoS and boom, everything is happy again. Just wondering if there is something lingering in the code that caused this just by turning off QoS? Thanks!
