Our main router is the RBR40 mini router. For the past 2 months or so our wifi connection has been cutting in and out for all of our Apple devices. The only exception is our Mac Mini, however it has a wired connection straight into our modem so there isn't a problem with it receiving internet. We've hard reset and factory reset our router and reconnected all of our satellites and wifi settings, yet the problem persists. Our phones will all get wifi for a few minutes and then will automatically disconnect due to there being "no internet connection", then it'll connect back in around 20 minutes minutes or so and the cycle repeats. Please help.
