Hi - I want to limit wifi to certain devices (i.e. my kids' devices) between 10 and 7 am. I have read the posts about parental controls and talked to FIDO. I have logged into my modem and located device filters, etc. I cannot get this to work. I have seen some people comment that the time zone is GMT. It is so confusing once you get into device filters. Has anyone had any success in selectively blocking devices with the FIDO modem? Is there a step by step guide available? Is there a certain modem that is easier than others? Thanks.
