My nighthawk bit the dust after 5 months in my house. We had a smart home with over 80 WiFi devices. Developed a problem where everytime the power flickered it would issue duplicate IP addresses to devices. I had to go to the breaker box and turn zones of the house on one-by-one to keep it from getting overwhelmed.
I know that’s a lot of devices, but this was a pro-sumer level router and wasn’t cheap. I could have got an entry level Cisco or Ubiquity for the same price. (I didn’t know about Ubiquity at the time)
It finally fried itself and in desperation I bought a Google Nest WiFi Pro 6e set of 2. Flawless for a year. I don’t like the limitations of the Google gear though, which is why we’re transitioning.
At this point, I pretty much recommend Ubi or eBay Cisco stuff to my family or friends, unless they have truly low usage.
