Help! After hours of reading reviews, I decided to buy this system. (I buy a Meshpoint separately, the set is too expensive for me). I would have liked to buy an Orbi, but the Parental Controls (I need the timeout) have to be paid extra there, same with Linksys. In addition, I need a Guest Network. Just before I pressed buy, I saw the comment that in "Bridge" mode the guest network cannot be activated. I have a UPC Horizon box and unfortunately know too little about network issues. Will my Amplifi have to be in bridge mode with this?
