The Buffalo WXR-1900DHP is not Wi-Fi certified. It defaulted to Auto channel mode on both 2.4 and 5 GHz radios upon power-up. The 2.4 GHz radio defaulted to 20 MHz Channel width, while the 5 GHz radio defaulted to Auto Bandwidth. The router comes with different 2.4 and 5 GHz SSIDs set, so you'll be able to connect to your desired band without having to change router settings.
For throughput testing, all tests were run using our Version 8 Wireless test process with 2.3 version firmware loaded. The router was first reset to factory defaults and Channel 6 was set for 2.4 GHz and Channel 153 for 5 GHz. 20 MHz B/W mode was set for 2.4 GHz and 5 GHz was set in 80 MHz bandwidth mode.
The Benchmark Summary below shows the average of throughput measurements made in all test locations.
Buffalo WXR-1900DHP Benchmark Summary
To put these average values in perspective, compare each of the four average throughput benchmarks for all AC1900 routers tested with the latest V8 process (pink bars). Not too much analysis is required here. The Buffalo ranked last in all of the average throughput comparisons.
Average Throughput comparison
For our throughput profile comparison, I selected the same products that we've been using throughout the review.
For the 2.4 GHz downlink, the WXR-1900DHP starts out with the other products, but quickly falls off at about 15 dB of attenuation. It remains below the pack and finally drops its connection after 54 dB of attenuation. At 57 db, The leader, the NETGEAR R7000 is still getting 32 Mbps of throughput.
2.4 GHz Downlink Throughput vs. Attenuation
On the 2.4 GHz uplink, the WXR-1900DHP starts with a lower throughput and remains lower than the other three routers in comparison until it again drops its connection after the 54 dB test. Note that the NETGEAR R700 (red square) has consistently higher throughput starting at 24 dB of attenuation, and its plot remains above and to the right of all of the others.
2.4 GHz Uplink Throughput vs. Attenuation
On 5 GHz downlink tests, the NETGEAR R7000 started out on top and never dropped below the other routers throughout the entire range of attenuation. After 6 dB, the WXR-1900DHP dropped below the other routers and had lower throughput throughout its remaining range. It was the first to lose connection after the 33 dB attenuation test. At the next test, 36 dB, the NETGEAR R7000 was still achieving 80 Mbps.
5 GHz Downlink Throughput vs. Attenuation
Finally, for the 5 GHz uplink tests, the story remains pretty much the same. The NETGEAR leads the pack throughout the entire range of attenuation. The Buffalo router started out lower, and both it and the TP-LINK lost connection after the 33 dB test. The Linksys and NETGEAR remained connected at 39 dB of attenuation with 17 Mbps and 43 Mbps of throughput respectively.
5 GHz Uplink Throughput vs. Attenuation
Looking at the components in the WXR-1900DHP, I thought there might be a chance it could compete favorably with the top-ranked AC1900 Router - the NETGEAR R7000 Nighthawk. But the Router Ranker for AC1900 routers shows the Buffalo with a disappointing #7 ranking out of the nine routers tested.
Looking at the routers ranked above it, you'll note that there are three that are cheaper than the $170 price tag on the WXR-1900DHP: the #6 ranked $125 Linksys EA6900; #2 ranked D-link $162 DIR-880L; and finally, the top ranked $164 NETGEAR R7000 Nighthawk.
The Buffalo WXR-1900DHP router turned in a disappointing #7 rank
Looking at the Ranker Performance Summary, you'll see that the WXR-1900DHP really didn't distinguish itself in any of the performance categories tested.

And that pretty much sums it up. With multiple products at cheaper prices that perform better, it's hard to recommend the Buffalo WXR-1900DHP.
