Best router to replace Nighthawk R7000

It was working fine until this morning. My partner and I couldn’t get a connection even though our devices were connected to wifi. Then when I tried to reconnect us, it said the password was incorrect even though it hasn’t changed. A quick reset of the router worked but after doing some googling it looks like it’s a common issue with these routers?! For their price point, definitely not worth the trouble. :(

To give a little info: we used to use the equipment Comcast gave us but it didn’t reach far enough. Now it’s just used as a modem. Our internet speed is 1000Mbps though I don’t think I’ve ever done a speed test that reached that amount. I play and stream my games and all of our TVs, stream sticks, and cable boxes are connected via WiFi. Really don’t know much about these kinds of things so any suggestions would be great!
