How would i go about reinstalling the existing firmware, i am definitely not alone with this issue as when i searched it up on the internet it came up with a woman with exactly the same problem, i had rules obviously on there before hand to shut off my kids phones at a certain time and come back on at a certain time but then i noticed random devices connecting to my router that i was not adding so for security purposes i hard reset the router by holding the button at the back in and started fresh so i could keep an eye on it, i even did a seperate wipe of everything by the settings in backup to factory reset and erase everything but the rules i had in there before were gone from the left side of the traffic controller but all still stored on the right under traffic analytics with now 0 way to turn them off or even access them, as of this i cannot make new rules to control their stuff as if i click the button on that disables all rules the old stored and untouchable ones come on with no way to get at them, i'll show you what it looks like. I understand this is a strange problem but if the software for all the units is obviously the same this could crop up on all of them if someone decides they need to do the same as me, sometimes a factory reset is needed but then will leave the customer with this.
