Geofilter on xr300 not working

I bought this router a week ago and the geofilter only worked for about 4 hours out of a week. Don't understand why it doesn't work. It's simple, block all ip addresses outside of range. But it seems to connect outside of zone more often than in. I've read other post about factory reset and rebooting everything. I tried all suggestions and i got it to work only 4 hours. I turn off ps4 for the night and next day doesn't work. I've blocks countless ip outside of range but it still connects to the blocked one's. Is only got one Job and it doesn't do it. I Need help
