Wireless Performance - Profile Comparison
The 2.4 GHz downlink profile shows very similar performance for all four routers. The only real difference is that the R8000 wasn't able to complete the test at 63 dB.
2.4 GHz Downlink Throughput vs. Attenuation
The 2.4 GHz uplink plot shows the Marvell-based Linksys WRT1900AC distancing itself from the pack at low attenuation (high signal) levels, but joining the rest from 27 dB on. This time both the R7000 and R8000 don't complete the test at 63 dB.
2.4 GHz Uplink Throughput vs. Attenuation
The 5 GHz downlink profile finally shows some differences. The NETGEAR R7000 does better at low attenuation, but along with the Linksys WRT1900AC, ends its run at 39 dB. I was surprised to see the ASUS RT-AC68U disconnect after 36 dB and equally surprised to see the R8000 make it all the way out to 42 dB.
5 GHz Downlink Throughput vs. Attenuation
For 5 GHz uplink, the Linksys again turns in the poorest results as signal levels drop and the R8000 again the best. Another repeat is the ASUS' disconnect after 36 dB.
