Performance

To test the performance of the TP-Link Archer D9 AC1900 router, I have devised a simple testing methodology to test the quality of signals at different distances and through obstacles using my Dell E6400 laptop fitted with a Broadcom 7260 Mini PCI-E card at 866.5Mbps, the fastest this WiFi card can manage and all tests are run on the (where I live, lucky me) zero traffic 5GHz range. To test the quality, I ran Speedtest (www.speedtest.net) and took down each result from the following locations:

–          1m away from router

–          5m away from router

–          15m away from router (Through 1 wall and walking down the road)

–          25m away from router (Though 1 wall and walking down the road)

The internet connection wired reads as follows:

Ping – 25ms

D/L Speed – 38.62 Mbps

U/L Speed – 8.37 Mbps

Now it’s time to test the router…

1 metre away from router:

WiFi speed – 866.5 Mbps

Ping –27 Ms

D/L Speed –36.51 Mbps

U/L Speed – 7.72 Mbps

5 metre away from router:

WiFi speed – 866.5 Mbps

Ping – 27ms

D/L Speed –36.59 Mbps

U/L Speed – 7.78 Mbps

15 metre away from router:

WiFi speed – 866.5 Mbps

Ping – 28ms

D/L Speed – 36.59 Mbps

U/L Speed – 7.66 Mbps

25 metre away from router:

WiFi speed – 866.5 Mbps

Ping – 28ms

D/L Speed – 27.50 Mbps

U/L Speed – 7.70 Mbps

As you can see from the results, the AC1900 performs superbly and to make matters even better, the 25 metre range consists from the middle of my first floor flat walking down the stairs and down the street, I estimated about 45-50m before it couldn’t run the test.  The ping is also relatively great and stable across all of the differences meaning the wireless signal emanating from the router is of great quality, much improved over the usual shoddy ones provided my any major ISP.
