Looking at selling the R1 on now as i just cannot get on with it.
It's host filtering works fine, but i am unable lately i am still experiencing lag spikes/latency problems while playing Black Ops 3 (xbox).
I started a thread a while ago about trying to cascade the router with the Superhub, as i get 200 down, 20 up from that, whereas i have never gotten above 50 down 14 up through the R1. Coupled with the 2G wifi which although worked, i was having regular lag spikes while streaming to my laptop.
I understand that my setup is probably unique to me, i also understand that streaming from the xbox app on my laptop also kind of undermines the point of using the R1 due to introducing more latency/lag. However, i can do this perfectly fine through the Virgin Superhub using it's 5Ghz wifi. It all points to the R1 having the problem. I get full speeds (+/- 10mbps) at all times of the day through wifi speed tests, whereas i only get 1/4 that from the R1. I have run though all the "fine tuning" guides and troubleshooting pages on the wiki numerous times, but nothing changes. Running the intergrated test mode shows everything as 'exceptional' yet i still find myself with a latency of over 150ms ping from the Xbox tests, and while playing the game, probably feels about right with people killing me through walls, or dying before i even see the enemy etc. Ping tests on the superhub show no packet loss and a 9ms ping.
Recently i bought a pair of powerlines, just to try them out with the R1, and i still get 'Network Quality' issues, although not quite as bad as the R1 wifi, still makes the game bearly playable.
In summary, i cannot recommend this to anyone who pays for high bandwidth internet, as the R1 just cannot run at these speeds. Even though i am connecting to local peers (0 ping assist, 700km radius) i still get lag spikes and a higher than average latency. Meaning that instead of 'Dominating', i might get 1 decent game out of 7 or 8. For the money i paid i may as well just use the superhub directly.
This is only my experience. If you find yours runs fine, well good on you, then i must be in the minority.
