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.
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.
