wrathoftank,
I assume you have an ATT Fiber modem. If so, I have a similar setup to you. ATT Fiber modem and an R2. I setup the R2 to go through passthrough mode on the fiber modem and left DHCP enabled on the R2. I only have my xbox and htpc connected to the R2, all other hardwired devices are connected directly to the fiber modem. I am actually using the WIFI6 on the fiber modem. The R2 is simply being used for geo-fencing.
The R2 will never detect the proper speeds of 1 GB up and down (its technically 950 Mbps up and down) but the R2 detected 900 down and almost 700 up so I stuck with those numbers. I turned QoS to always on and set both sliders on 70%. I ran the bufferbloat test on the test website on both my desktop pc (directly hardwired to the fiber modem) and on htpc. The results are A+ with the R2 and only A directly from the fiber modem. my ping on COD is often in the mid 20's now. This setup works for me because even though most all my internet capable devices are all hard-wired, rarely am i using multiple devices at once. Using a Netgear GS308 managed switch for those. And wireless devices like phones or tablets are only connected when needed. Connect your Eeros directly to the fiber modem, factory reset your R2 and reconfigure. The benchmark test results on the R2 will be inconsistent but even if you dont get full bandwidth playing COD, you dont need it. Getting bufferbloat down is the biggest difference maker there.
