Introduction

With Wi-Fi 6 on the horizon, TPLink launched a series of Archer wireless routers aimed at lowering the cost of entry for the budget-minded consumers. The high-end of this lineup is the Archer A20; an AC4000 Tri-band solution.

With the Archer A20 in house, we move to the build which sees this unit as an AC4000 class platform utilizing the Broadcom BCM4908. This is a quad-core SoC operating at 1.8GHz paired with 512M of memory and 128M of NAND flash.

The radios supplied are BCM4365E allowing this unit to take advantage of 1024QAM; this means 1625 Mbps for each 5GHz band and 750Mbps for the 2.4GHz band. Wired connectivity is managed through the 4908 SoC with four LAN and one WAN port. Additional connectivity is offered via USB 2.0 and 3.0 ports.

MSRP of the TP-Link Archer A20 comes in at $199.99 with a two-year warranty.

Benchmarks - LAN and WLAN Throughput

LAN and WLAN Throughput

19

Testing followed our standard procedure with the test system listed above. For LAN throughput the Archer A20 did quite well offering 946mbps

19

Wireless throughput started with the A20 reaching 154.98 in 2.4GHz and 661.44 in 5GHz. The second 5GHz band produced 654.82 putting this router just under the C5400v2 in our charts.

19

Mobile throughput offered 541.95 with our iPhoneXR, second in our current charts.

19

Above, we have throughput at distances of 5,10,20 and 30ft line of sight. For the Archer A20, we start at 77Mbps at 5ft and moving out to 10ft we see a slight increase to 96.4Mbps. At 20ft this regresses to 81Mbps, and at 30Ft we hold 85Mbps.

19

We have the same thing here for the 5GHz band. For this test, I was able to put the Archer up against the Deco M4 in single and 3 node setup. The Archer starts off strong at 538Mbps and moving out to 10Ft we hold that performance at 541Mbps. At 20Ft we see a sharp drop to 374Mbps and at 30Ft finishing up at 333Mbps.

Final Thoughts

After spending a good amount of time with the Archer A20, I can certainly say that while this unit is a good amount cheaper than the C5400 it gets its design from, it feels solid both physically and in use. I was able to use this unit in my own home network for a solid month and taking from that I had no issues with streaming, gaming or day to day browsing activities. Build quality is just as heavy as the C5400v1 we reviewed in October of 2016, or the v2 we looked at in September of 2017.

19

Taking from those two units its design, internally the Archer A20 takes a new route opting for the BCM4908 over the aging 4709 and new Wi-Fi chips with a 3x3 design over the C5400's 4x4 setup. This lowers costs marginally without sacrificing much in terms of real-world performance. As you can see from our charts the Archer A20 outperforms the C5400 in wired throughput and beats the v1 in wireless throughput by 200Mbps, the v2 does have a slight advantage over the A20 by 40Mbps.

As for the GUI, the addition of homecare is certainly a plus as it gives a basic foundation for both malware and anti-virus protection and the added intrusion monitors offer better peace of mind. The QoS functionality has been improved allowing for device and application priority to be configured and the parental controls are more customizable than ever.

Pricing is king and with the Archer A20, TPLink is offering tri-band functionality with its AC4000 platform for $169.99. the next closest comparable solution is the ASUS RT-Ac3200 at $199.99 followed by the TPLink C5400 at $215.99
