Extremely slow CBR40 Speeds, need help
I have the "Ultra Fast" 900mbps Xfinitity plan with a CBR40 modem/router and RBS20 satelite. I've never seen speeds quite near 900, but in the past it's been quite good (at least 300-400mbps over Wi...
I'm in a similar situation. Xfinity 600 mbps plan connected to Orbi CBR40 and 2 satellites (RBW30 and RBS50Y). On Ethernet (AppleTV, Speedtest app) directly connected to CBR40 I actually get better than advertised speeds at 715 mbps (don't tell Xfinity). But when I use a WiFi device I'm maxed out at about 300 mbps (280-315). Beamforming is enabled and MIMO is enabled, and 20/40 MHz coexistence is disabled. WiFi devices are on 5GHz and "connected" to the CBR40. 8 devices are on the WiFi network. WiFi space is pretty dense as we're in an apartment complex but S/N seems good inside our apartment. I'd expect WiFi speeds to be a little higher maybe in the 500 mbps range.
What's the fastest speeds people have seen with their CBR40 on WiFi?
The speeds you are seeing are generally normal for something on 5Ghz AC. Most devices max out at 300-500 depending upon there design. If your in a noise wifi environment, this can cause problems as well. Try turning down the power output of the RBRs wifi radios from 100% to 50% and see if this changes anything. Under Advanced Tab/Advanced Settings/Wireless Settings

50% power dl speed was 275 mbps
100% power dl speed was 314 mbps
