Hello,
Unfortunately, only one of these two functions (network acceleration and parental control) can be enabled. Truly sorry.
Because after network acceleration is turned on, the network packets are not processed by the CPU, but by a separate acceleration chip; the parental control needs to filter and process the network packets, and it requires the network packets through the CPU, so network acceleration requires to disable.
You can set up another router as the main router for adults to use, while this Flint2 disables network acceleration and enables parental controls for kids.
