The app won’t start? Won’t connect? Does it give you an error? What device is it? 

You didn’t give much for details. 

Yeah, I have the same problem. Came to the conclusion since I have 2-W30 models (both doing the same thing—-flashing between orange…blue etc and did a factory reset) that they are a POS. Back to Netgear I go!

Haha…want your details. The Surfboard app for this model is old and a POS (Hence the one star rating on Apple) Hasn’t worked in a while (6-8 months). Before the app worked fine for a while (first purchased these models back in 2020) and then turned to junk and didn’t work at all. My WiFi devices slowly had problems connecting but we’re not a priority on my end. Today tried to reset both the W30’s and they won’t connect to anything!!!  Flashing light of death. What a waste of money!!’
