Wireless Adapter Blinking Red, And More

When I first installed the wireless adapter last year, the light was always blinking red.

A few months ago we had a power outage. When power was restored, the light on the wireless adapter was a constant blue, no blinking at all.

This morning we had a brief power outage, a few seconds. When power was restored, the light on the wireless adapter is once again blinking red.

All Ooma phones are working fine.

I read other posts, some saying that the light on the wireless adapter should be a constant blue; otherwise, it is searching for a connection. Other posts indicate that a blinking red light means it’s working, and that a blue light means that it’s connected to a wireless phone.

I’m confused, and I’m looking for guidance. Should the light on the wireless adapter be a) blinking red; b) be a constant blue; c) blinking blue; d) blinking red/blue?
