Nighthawk R7000 Problems

need some help here and i wanted to turn to the community.  i've gone through the posts and it seems like this router just isn't very good, but i wanted to check to see if i'm doing anything wrong.

ever since this covid business, my wife and i are home and the problems with my router are getting ridiculous.  for some reason, my nighthawk just stops working and i either have to reconnect from my computer(s), or power down/up the router.  this happens at least once a day.  my computer will no longer be connected and i have to reconnect.  and other times i have to reboot the router.  same with other devices connected to it, like my roku.

what things can i look into to fix?  is running dual-band a problem?  are there are any settings i should look to update or adjust?

i updated the firmware when the update was available.  i've noticed a lot of negative feedback from the last version--88 i believe.  i'm running my router dual-band with both 5mgz and 2.4 mgz.  i do not have a guest network running.

one thing i noticed when i was originally troubleshooting was that ntp was not turned on and i did turn that on.  seems like a minor thing but i made sure that this worked right.

should i downgrade my firmware?  i've read that there is a stable previous version before 88.

should i just get a new router?  it seems ridiculous that my wi-fi router is going out...in 2020.  sure i've had this a couple years at least so it's not exactly brand new, but come on, is this something that i should really have to be dealing with?

thoughts and any advice on troubleshooting would be greatly appreciated.  i'm not happy right now, and am about to just go out and buy an eero system.

firmware version is:

V1.0.11.100_10.2.100

thank you for future replies, in advance.
