ASUS RT-AX88U Pro (AX6000) Dual Band

I just sent customer support a long email. I got this yesterday, super excited about having a state-of-the-art router to replace my 2-year-old Netgear that's dropping constantly. I'm not an IT expert by any stretch, but I'm pretty good with computers/networking and can usually figure stuff out. Wirecutter says that this router is probably "overkill" for someone like me, but overkill is what I want in a wifi setup in a house with four internet users. When I set up the ASUS yesterday, it all seemed to work perfectly. I used the Asus App and set the router to my old router's name and password so my wireless devices would connect easily. This seemed to work at first, and devices like my phone, laptop, and Amazon Echo devices worked great. The App said my setup was terrific. I asked Alexa for the news, and she gave it to me like everything was fine. And she was so quick and responsive! I figured I was golden. Then, the wifi dropped. And I realized my Kuna camera devices couldn't connect at all. Sometimes my laptop would connect, sometimes it would not. The Amazon Echo/Alexa devices now don't "see" the internet at all even though they're connected to the wifi. And even though they, at one time, worked just great with the new router. At some point, I realized that NONE of the devices I had plugged in through my 16-port unmanaged switch were connecting to the internet even though the switch was connected to the router. The lights blink and it looks fine, but nothing connects. When I connect directly to the router and not through the switch, a device would work. I thought maybe it was because it's a Netgear switch? But that doesn't really make any sense, and I see nothing on the internet about it being a problem. I restarted the router and had the same problems with wifi and wired devices. Then, I updated the firmware as another reviewer suggests. That seemed to help, but still not everything would connect. I also turned off the advanced wifi setting features (the 802.111ax or whatever it's called) as a reviewer also suggested. That almost seemed to help, but today, NOTHING AT ALL would connect. Not even my phone or laptop. NOTHING. And nothing wired through the switch, either. So, I did a hard reset by pressing that red button on the back, and I started over. I also turned off the advanced wifi setting. That seemed to help a lot. 20 wireless devices were shown as connected to the router by the App. (Yesterday, I never saw more than 7, when my app would connect at all -- by this morning, the app couldn't connect at all to the router). But my laptop and my Alexa/Echo devices still do not work. I reset them and tried to connect, and they connect to the network but they say there's no internet. It's the same with my laptop -- no internet, either wired or wireless! My Kuna cameras and phone and a few other devices DO connect wirelessly now. But my laptop WON'T CONNECT AT ALL (wired or wireless, even though it can see the network and it DID work on the wifi network, intermittently, yesterday). I tried calling tech support, but after going through the menu there's just dead air. I couldn't tell if I was on hold or not. The menu lady suggests I use their support page, and the flyer in the box says to email them, so I did. I stayed "on hold" with dead air for 20 minutes before my phone told me that if I would like to make a call, I should hang up. So, I guess tech support hung up on me. Honestly, I'm about to just pack the ASUS back up and return it. I just plugged in my old router again, and it's a joy to have all my devices back online again after a day of spotty or zero internet at all. I think I'll probably look for a well-reviewed Netgear router because the Netgear people at least answered the phone when I've called in the past.
