I am about to upgrade to a new AX5400 router just released by Asus (I have 4 devices supports wifi 6 at home) This is a brand new router design with just the original firmware. What are my risks? Does major brand do enough testing on their products before release or they rely on early adopters as their beta testers? Also, if I run into issues with the router. Should I try to return within 30 days or wait & hope they will fix it with firmware updates?
