Keith, this is exactly the same issue I chimed in on early in January. I respectfully disagree with your assessment. I believe this is a software issue. At your prodding I returned my device after exactly this behavior. The replacement is doing exactly this, exactly as was reported in this forum post, just as the previous one did. Can we get to the bottom of this already? Stand alone access points are the only ones seeming to have this problem...
Btw, if I reboot it 10 times, maybe twice in ten will it bring up a wireless interface. If I factory reset, it works for "a while" before this behavior restarts.
Sorry 😞
Peter
