AC1900

Since there were four AC1900 routers retested, there were multiple ranking changes. NETGEAR's R7000, which was not retested, remained in the #1 spot, but is now tied with ASUS' RT-AC68U, followed by its updated sibling, the RT-AC68P. The TP-LINK Archer C9 moved up a bit and is now ranked above D-Link's DIR-880L, which moved from #2 tie to #5.

The only router that didn't improve its rank with retest was Buffalo's WXR-1900DHP, which retained its next-to-bottom rank, beating only TRENDnet's TEW-818DRU.

AC1900 Ranking Comparison

Comparing Ranker Performance summaries of the two #1 ranked AC1900 routers shows there is more than one way to achieve a #1 rank, i.e. no product is #1 ranked in all benchmarks.

Ranker Performance Summary comparison

Comparing 5 GHz downlink throughput vs. attenuation plots of the four retested routers show a general upward shift in the curves. Note although the Archer C9 doesn't have the highest 0 dB attenuation throughput, it equals or betters the other three routers from 6 dB onward.
