Nighthawk R8000 AC3200 with Spectrum Modem connection speed should be 400mbps but avg 150-190

I have spectrum as well and have the same issues... I have a PC desktop and at the desktop always get good speeds via ping, and via basic web speed text other than spectrum's test webpage.

I have two problems and not sure where the choke point is...  I have a great reduction of speed that seems to drag after the router has been active for a while since I have cycled the modem and router.  I even checked to see if Spectrum is throteling their bandwidth which I have reasearched an they are not.

I also have had a MAJOR issue with 2.4 and 5 drop out randomly with my wifi.  The router also seems to "forget" devices when they are idol for more than a few minutes.  I have a TV that is literally 4 feet vertically from my router and sometimes the 5 will end up so slow it will buffer netflix.  Which again like you I pay for 400 speeds, and this will be the only thing online at that time.

For what it is worth, I run the following in my house:

4 Amazon fire sticks - Never running at the same time

Arlo Cameras - 4 into it's own base station hard wired

1 desktop PC Hardwired

Skybell Doorbell - This for some reason keeps dropping off of 5-  and is always ends up offline

5 google pods

2 tablets

3 laptops

1 iphone 

2 android phones

I have a ton of cross traffic on the channels around me because I live on a corner lot, so I have tried manually setting my channels and this eneded up making things worse.  I have reset the router back to original settings twice, and moved devices around so they are not too 2.4 or 5 heavy.

I have both the drop out and speed issues that seem to be random.  I can say on speed, I have been told that Spectrum tells me that due to people working at home, Cable is based on how many users it has on their pipeline.  I have also been told that the business users get priority.  So the more people the speeds slow enough that you can tell a bit... it should never drop enought that you can't run what you need though.

Hopes some of this is helpful.  I have been fighting Spectrum for years on the speed and connection, but always had a good netgear router, I upgraded to this one and now nothing is working... I am at the point of just cutting my losses and buying an ASUS or Lyncsys.  The ratings are higher they are a better value as well, according to the reviews, the interface is more user friendly and setup is more automated.  I am 6 months into this router and it has been an uphill battle the whole way of trying to configure it and everything has worked for a day or two and then it quits
