My first modem blew up in a storm. I replaced with the archer vr300 specifically so I could use the tether app and make use of parental controls (via app). However, now I am all set up with this modem the app is missing features that were available previously with first modem (don't recall model). For example I could assign a user and set up all devices under that user (thereby setting one schedule for this user / child). With this modem I have to set schedule for each device. I could also see everything's speed the first time around as well as view search history. All these features aren't available with new modem even though it is the same app! Does any one have any assistance with this?
