Ring doorbell 2

My ring has been working fine for months. It is hardwired/powered by old doorbell. Recently rebooted Netgear router and at some point noticed I wasn’t receiving alerts. Checked dashboard and it stated not hooked up to WiFi. I went through the reconnect instructions and it has failed to reconnect. Called tech support and went through it several more times and no luck. The accent from the tech support person didn’t help matters as I am hard of hearing. Any suggestions?
