I bought the R8000 model back in November 2019, and it worked great until the last 2-3 months, but this past 2-3 days I've noticed it has gotten significantly worse.
Worse at what?
----- in terms of keeping a stable connection. I would be browsing, than all of a sudden It'll take forever to load any page including google.com or just basic websites in general (yahoo, google. cnn, fox, school websites, etc), sometimes at the bottom left of my browser it'll be stuck at "resolving host" or whenever I type something in the address bar and hit enter, whatever I typed in would disappear and have a large delay of what typed in and suddenly it'll load my page. The DNS issue occasionally happens, but not all the time. As I'm writing this it's even happening now. The connection seems just so unstable at times, I can be browsing and doing my normal school work and it works fine, than within a blink of an eye I start to experience all the issues mentioned above. What's really strange about any of the connection issues I just mentioned also is that my router lights are always blinking, even when the issues are happning, I just noticed the lights will stay solid for a good 4 seconds when the issues are happening and then blink, not sure if that helps but ya.

You haven't said much about what is going wrong on your router.----see first response above

It loses the Internet connection?----See first response above

As I said before I've tried contacting my ISP and they've came out twice and tested my lines and modem and said it was fine. They think its my router, and I'm starting to believe that as well. I've tried a DNS flush, clearing my browsing history and cookies. I use Chrome primarily but I notice this issue still persist on other browsers like microsoft edge, and firefox. I'm not super computer network saavy, but I can't seem to figure out what else I can do to fix the router or to can it and just get a new one. I've gotten to the point now where I have to reset my mode and router at least twice a day, and its annoying as F.

  Unfortunately, I still do not have much of an idea about what happens at your end.
  
  Your detailed explanation seems to add up to "it doesn't work".
  
  It seems that you are using a wifi connection. But you don't say. Have you tried using a wired connection in the router to check if that also freezes?
  
  It seems that the wifi LEDs are behaving as expected, but you don't say which one are blinking or going "solid".
  
  So, let's start at the beginning.
  
  What is the modem, if there is one, in front of this router?

    Modem I'm using is---Motorola MB8600 DOCSIS 3.1 Cable Modem, 6 Gbps Max Speed. Approved for Comcast Xfinity Gigabit, Cox Gigablast, and More, Black
    Modem Lights: Works fine, nothing wrong.
    COX Cable is who I have (Plan I have is--300 down, 30 up)
    
    Router-R8000
    Lights that are on Router
    Power-Solid white light
    Internet- Blinks White
    2.4ghz-- will stay solid white for about 5-10 seconds than start blinking white
    5gh1---will stay solid white for about 5-10 seconds than start blinking white for about 4-10 seconds/repeat from beginning step
    5gh2---will stay solid white for about 5-10 seconds than start blinking white for about 4-10 seconds/repeat from beginning step
    WPS-Solid---white light
    Wifi On/Off-- Solid white light
    
    Error's Im getting when browsing On Chrome, Firefox, internet explorer are- " No internet followed by below that message " DNS_Probe_Finished_No_INTERNET. This happens when it doesn't load a webpage such as google, yahoo, or anything for that matter, and it seems to happen sporadicly at times.
    
    When I run a windws network diagnostics some issues are always found such as the following: Issues found----> The DNS server isn't responding (detected), than below it'll say " The DNS server isn't responding, Your computer is trying to use a DNS server that is incorrect or doesn't exist.
    
    Troubleshooting Tried: Contacted ISP (They came out and said lines are fine, modem is fine, its getting the signal, possible router might be degrading or defective, mind you I've had the router for 14 months now)
    
    ---Restarted Router, Unplugged modem cables from coxial line and plugged everything in.
    ---Factory Reinstalled modem from scratch and downgraded to firmware to V1.0.4.28_10.1.54, because based on what I read it seems like what's what most people have done considering the newest firmware is terrible.
    ---Replaced Ethernet Cords for mode to router
    --- Plugged router straight into desktop and i get the expected speeds from what the router can do at best, which I get usually 186-254 mb down, and 29-30 Up.
    --Ran speed test on speedtest.net and always picking my home city, and I consistently range from 154-225 down, and always 29-30 up.
    
    Currently I have to reset my connection about 2-4 times a day, and its just not stable. I'm currently running the older firmware V1.0.4.28_10.1.54, and I still have issues, so at this point I have no idea what I need to do or if I should just get a new router.
    
    I do use a wifi connection through my router, and all my devices(4) are either on 2.4 and I have 2 devices per 5ghz band
    
    Not sure what else your wanting me to provide as I've pretty much summed up my experience with the router. I've said this from the get go, the issue is dropped connection constantly followed by a "resolving host" to DNS error of some sort, and within 30 seconds to a minute it works agian, and it repeats until I unplug everything which is just plain annoying.
