Sorry about the issues you're having with your WiFi points. I'm sure that's frustrating. We have a guide here that indicates what the different status lights mean: https://bit.ly/3gvzkoz. Looking at the list, a flashing red indicates a critical failure and the first suggestion is a factory reset, which you have already done. From there, it's recommended to contact support through the link found in the article. To save you some time, here's the link: https://bit.ly/3p0uyC7.
