With only one OpenWRT One as the main router, you mean?
2 of mine are dead, I'm using 4 now, and I am pretty sure at least one more is on its way out. Long story short, Severely bad storm about a month ago took out more than a few things electronic in my home, including my fridge and upright freezer in the garage, and a couple of these nodes as it is. But even with stock Linksys firmware this lack of ability was evident, I was losing 10% to 20% versus what I get connected directly to my AT&T box (residential gateway).
Frankly, I don't trust them.
But, I could do so in a pinch, get only one "One" for now, and slowly replace them, spreading out the cost over time.
