im assuming you have latest update? you said you reconfigured same network meaning your forget network and reconnect? are you on 2.4 or 5G or you have both in one network? try to split and connect on 5G first then 2.4 to see if that helps. try different router if you have avaible or swap to different if it belongs to your ISP.
if nothing works then I would say try factory reset option and see if that helps
it locks channels and works as parental control. for example if you dont want anybody to watch certain channels then you can lock or hide/lock. so if someone tried to watch they have to enter lock code/PIN number.
found update, downloaded and box boot up fine. I did not see installation screen. I guess it happened so fast maybe. everything is working so far and shows new versions as well.
