X55. I installed and it worked perfectly the first day, very next day it started blinking blue. Can't connect to deco per app. I followed all the steps, then checked a thread online. When none of the above worked, I deleted my network and started from scratch. Once again, it worked the first day but the very next day blinking blue and cannot connect to deco. I decided to try deco with the reviews and thinking I could use less and have the ones for outdoors but I with what I do I need a reliable internet and I may have to go back to my old mesh points. Any insight before I do how to correct?
