help achieving actual isp download speeds (wifi)
Recently switched my home internet hardware setup and upgraded my ISP plan. I pair the r8000 with a CM1150V xfinity approved modem. I achieve max downloadspeed via ethernet (roughly 950mb/s). I just ...

If you are subscribed to a 1200mbit download plan, then avoid using the QOS function on the router,as it will be rare to saturate the connection.
For WiFi performance, it is an 802.11ac router, and if using a common 2 stream 802.11ac WiFi adapter, then the max PHY rate you will usually get, is a PHY rate of 866.7 Mbps , which translates to a real world throughput of around 550-650Mbps under nvery good condition (close to the router in the same room).
If you want a WiFi connection that can take full advantage of gigabit internet speeds, then youneed to use 802.11ax with a card such as the Intel AX200, which on a 2 stream connection to an 802.11ac access point, can reliably do 1600-1700 Mbps real world speeds from the 2400Mbps PHY rate. But better than that, even 30-40ft away, they can still sustain over 1000Mbps.
Outside of that, you will need to use a wired connection in order to enjoy the full throughput of your connection.
The QOS in the R8000, impacts the WAN port, by prioritizing different tiers of traffic, but if you have a single gigabit WAN port, and your ISP overprovisions to 1200Mbps, then you will never reach a point where you can saturate the WAN connection, thus QOS will not really benefit you in terms of ping times (though it can help in terms of ensuring that a ton of bulk traffic such as downloading a steam library will not cause a netflix stream to fail).
PS, if your ISP is truly giving over 1Gbps, then to enjoy the full speed, you will need a router that offers port teaming / LACP to get an effective 2Gbps connection between itself and the mobem.
Wanted to also get more info, which WiFi adapter are you using on the client device?
Razor512 I can't thank you enough for all this information..questions that I have been dying to have some insight on. In my desktop I run an Intel Wireless AC 9260 within my TUF GAMING X570-PLUS (WI-FI) mobo. I am now doing some research into a compatible router with LACP support and module like the AX200 you mentioned.
For the AC 9260, it is a dual band adapter that supports 160MHz channel width on that band, this makes for a PHY rate of 1733Mbps, and usually a real world throughput of around 900Mbps
This article shows the 160MHz performance with your WiFi adapter. https://www.smallnetbuilder.com/wireless/wireless-features/33212-160-mhz-wi-fi-channels-revisited?start=0
For your motherboard, instead of using an m.2 WiFi adapter, they instead use the a smaller 1216 style form factor that is soldered directly to the board, thus they cannot be replaced, so an upgrade on the desktop, would essentially have you using one of the m.2 slots, though in that case, for best performance, you would essentially be using either a PCIe to m.2 adapter, for example, https://www.amazon.com/Desktop-Wireless-Network-Converter-Including/dp/B01MFGYAX6/
Though at that point, it would be cheaper to just run some Cat 6 between the router and your PC.
Another option on a desktop is using the chipset connected m.2 slot (one near the bottom of the board), and a u.fl to rp-sma connector adapter to attach some antennas to an expansion slot opening on the case. Furthermore, the AC 9260 wil have to be disabled in the BIOS/ UEFI settings for the motherboard). Save the top m.2 slot for your NVMe SSD since that connects directly to the CPU and does not share bandwidth with anything else, while the chipset lanes share 8GB/s worth of throughput with everything on the chipset.
While there is no noticeable slowdown in the vast majority of cases, it is possible to notice a slowdown on an NVMe SSD on the chipset m.2 slot if while reading from the m.2 SSD, you are also accessing a number of SATA SSDs, in addition to also accessing one of the 10 gigabit USB ports with high throughput components all at the same time.
Beyond that, if using even 802.11ax,when using a 160MHz channel on the 5GHz band, part of the signal will extend into the DFS frequency range, which by law requires transmit power to be limited to 250mw transmit power. While in many cases it will not be an issue, if you are far from the access point, it could result in there not being much of any performance boost, or worse, if in a congested environment, slightly slower speeds than on the 80MHz channel width, thus it is something to experiment with. Basically if you are multiple rooms away from the router, then you test both 80MHz channel width, as well as 160MHz channel width to see which offers the best performance (it is pretty rare to get a performance drop on 160MHz).
Forgot to add, the 160MHz tests in that article was done using an R7800, which has known compatibility issues with the 9260 when in 160MHz mode, but with newer WiFi radios, it should not have those issues.
