Last year, I bought a really nice ASUS RT-Ax3000. We have AT&T Fiber internet and pay for 1000mb/s download speeds. Our internet has worked really well for a year.

We have everything hooked up to this thing wirelessly: Sonos, HVAC, the garage door, Google Home, Nest, security cameras, etc.

About a month ago, it seemed that everything in our house was spotty. Then, I looked and realized all the lights in our router were out.

The router still works, everything is now running smoothly, and there is no NOTICEABLE issue with our internet. But now we are only getting 150mb/s.

Can I replace my router with the same one, keeping all the network names and password and the same, and avoid having to reset our entire house? Any advice?
