Wireless Reviews

Wireless Performance

The OnHub was tested using our V8 Wireless test process. Through the controls Google provided, I was able to set the OnHub to Channel 6 and 20 MHz bandwidth mode for 2.4 GHz and Channel 153 and 80 MHz bandwidth mode for 5 GHz. The test client was connected using WPA2/AES encryption.

As before, OnHub was centered on the test chamber turntable, with the front of the router facing the chamber antennas for the 0° position. This time the outer cover was left on during testing.

The retest Benchmark Summary below compares the average of throughput measurements made in all test locations from the retest (left) and original (right) tests. There wasn't much change in average throughput for either band.

For the throughput vs. attenuation profile comparison, I mixed things up a bit from the original review. This time the NETGEAR R7000 and lower-ranked TRENDnet TEW-818DRU and ASUS RT-AC68P are compared. The original plots are available in the previous review.

2.4 GHz downlink shows the OnHub (TGR1900) at the bottom of the pack, below even the TRENDnet TEW-818DRU that ranks just above it in the Router Ranker.

The 2.4 GHz uplink plot shows a tighter grouping for the four products. This time the OnHub does slightly better than the ASUS RT-AC68P from 27 dB onward.

The 5 GHz downlink test summary leaves no question as to the positions of each product. The OnHub once again comes in at the bottom of the compared group.

The 5 GHz uplink plot again has the products tracking more closely. The OnHub is the lowest line for the entire plotted range, closely tracking the TRENDnet for most of the tested range, with the ASUS joining at 18 dB onward.

Closing Thoughts

The Router Ranker once again places the TP-LINK Google OnHub in last place, this time at #12 out of 12 AC1900 class routers tested. The Ranker Performance Summary shows the 2.4 GHz range sub-ranks probably contributed to the bottom rank, since neither uplink nor downlink made it to the 54 dB test used for this sub-ranking.

Since Google said their tests showed the TP-LINK OnHub "compar[ing] favorably to competitive solutions" in open air in-home testing, I ran additional tests in both bands. But each time, the results were consistent.

So if you've got a TP-LINK OnHub and have noticed improved wireless performance with the new firmware, please let us know in the Forums using the link below or via comments@smallnetbuilder.com. But our bottom line on the TP-LINK OnHub remains the same: nice to look at; meh wireless performance; and a minimalist feature set for folks who just want to plug something in and get their Wi-Fi mojo working.
