TP-Link Archer A20 Speed Test
TP-Link Archer A20 Speed Test

Operating simultaneously on tri-bands, the Archer A20 delivers theoretical speeds of 750Mbps on 2.4GHz, and 1625 Mbps each on its dual 5GHz channels. The aggregate speeds of 4Gbps and multiple data streams bring a lot of potential to your internet connection.

With the 1 Gig plan from AT&T Fiber, the speed tests were astonishing. In the proximity test, my iPhone 11 Pro max connected to the 5GHz band clocked over 820 Mbps of download speeds. The upload speeds reach close to 490 Mbps within 5ft of the router.

Over an Ethernet line, I observed my PC hitting download speeds of 900 Mbps with ease. The upload speeds remained well above 500 Mbps. This was pretty impressive for a WiFi-5 device. The legacy devices connecting to the 2.4GHz band raked over 250 Mbps downloads and 5Mbps uploads.

Coverage & Connectivity

The TP-Link Archer A20 range extends itself to over 3000 Sq Ft. An excellent choice of router for larger multiplex homes with smart home devices. Credit to the 6-range boosting high-powered antennas encircling the devices, the router can cater to large surface areas.

On top of the range boosters, the antennas are reinforced with beamforming, the technology which detects usage and focuses signals towards the devices. The laptop sharing the wireless bandwidth could run multiple streams of YouTube videos in HD quality with no hindrances.

With MU-MIMO technology, your devices get reduced waiting time for data transmission. This allows close to 40 devices to share the network with ease and access high speeds. The router comes with 4 Gigabit Ethernet ports. Connect all your primary devices to the Ethernet port. TV desktops, laptops, and gaming consoles will have access to the stability of wired internet.

One of the biggest advantages of Archer A20 is 2 USB ports, 1 USB 3.0, and USB 2.0. Connect your printer to the USB 2.0 port and the NAS device to the USB 3.0 Port for fast data transfers. The test read and write speeds from our hard disk to laptop were comfortably above 50 MB/s, which makes this an excellent fit for smaller offices.

Service Package Suitability

TP-Link AC4000 Tri-Band WiFi router can handle up to 1 Gigabit package. If you are living in a household with less than 10-15 devices, an 1 Gigabit plan will be an overkill. The 300-500 Mbps plans of Verizon. Cox, Xfinity would be sufficient. Choose the right plan according to usage and preferences.

Household with gaming enthusiasts, twitch streamers, content creators, office setups, or smart homes; If you fall under any of these categories, go for a 1Gbps connection with Google Fiber, AT&T, Verizon FiOS, or Xfinity.

Security Features

A standout feature of TP-Link AC4000 is its superior security features. Apart from the standard setup of the WPA2 encryption standards, SPI firewall, and access controls, TP-Link offers commercial-grade protection with HomeCare.

You’ll have access to a detailed set of notifications and reports with protection from Malicious sites and Port Intrusion. The router also checks for external infected devices and isolates them from the network.

If you live in a household with kids, you could hardly go wrong with detailed parental controls. Create dedicated profiles for your kids, map the devices to the profile, and set up access rules and content filters for the profiles. You’ll be able to schedule their internet access, block applications, and access a detailed report of their internet activity.

TP-Link Archer A20 Setup

Irrespective of your choice of model, the TP-Link web portal, or the Tether App, the installation is quick and simple. The interface is user-intuitive for the newbies to pick up and get used to the network management in no time.

The tether application allows you to prioritize the bandwidth for your devices. You can choose the type of activity, gaming & streaming, and assign bandwidth proportionally to these activity groups. Once you add smart home devices to the application, you can automate them with triggers.

Hardware & Internals

TP-Link uses a Broadcom-based 64-bit processor clocking at 1.8Ghz. It also has three co-processors to help the router handle the data loads. The 512MB operating memory and 128MB flash storage come into play when the smart home devices are attached to your router.

We tested the performance with the gaming sessions on PS4. Wired to the router, I ran a few sessions over the week with Assassin’s Creed and The Witcher in medium-high graphics settings. The performances were seamless.

We tested music streaming, surfing, and video calling with no hassles. The router was connected to our camera throughout the week, which hardly affected the overall performance. At any point in time, at least 20 devices were hogging down the internet; the Archer A20 was able to handle it pretty well.
