Recently updated firmware RT-AC68P to 384.11 & 384.12 from 380.xx having issues with packet loss to web on devices that have parental control time turn on during allow time period. Pinging the router with no drop, ping google dns/opendns will show packet loss cutting in and out. Maybe fine for a minute then starts dropping packets. Enough for kids not able to stream or play online games during allow time. Disable & block works fine, disable allows internet access with no packet loss.
