@jimas Thanks for the info, although my router type has different user interface with what it show on your link you shared. 

I do understand how to set parental control and what it means.

I am wondering how control mechanism between time limit and bedtime, and then how router calculate online time limit.

in the time control, there are 2 settings to be defined:

1. Bed time: I am aware that during this period time, internet access will be restricted at all for those devices attached to this profile.

2. Time limit: it is described as daily time limit for total time spent online.

So, if I set bedtime for 10pm-5am, no internet traffic at all during that period, and I can confirm it is working well.

And then beyond bedtime period, when internet allowed, my question is how router calculate defined time limit: is it measuring total time when internet traffic come & go, or total time when a device attached to wifi? How does it work? As my experience, time limit is not always working as expected.

Hi @Kevin_Z thank for the response,

I was playing around parental setting lately, I put also my Ipad along with my kid tab (Xiaomi Mipad 4) just to check what its behavior 

So here what my findings:

- bed time is working perfectly, both could not access internet during defined time

- when bed time is passed, my Ipad able to access internet, while mipad4 remain could not access internet. I need to toggle wifi connection on Mipad then I got internet access back. So I think the issue on Mipad. Then I used both to watch Netflix, around next an hour, both ipad and mipad4 could not access. Time limitation is working well.

- I put also my iphone and samsung galaxy to the time control profile, just to make sure. I found parental setting working flawlessly on both phone.

Therefore, I conclude that parental control on C80 is working well.

There might be some devices out there that are not working flawlessly with parental control feature like what I got with Mipad4. But it is not a big deal for me.

Thank you
