TP-Link Archer C8 Wi-Fi router review: A solid price-to-performance ratio saves this otherwise mundane router
As such the Archer C8 is one of the less-expensive 802.11ac routers you'll find, and it has several nice features including three removable antennas, beam-forming support, and two USB ports (one of which is USB 3.0) for sharing storage or a printer on your network. Printer sharing is disabled by default, though, and you'll need to install a utility on a client PC if you enable it. The Archer C8's other major features include a four-port gigabit switch and an 800MHz dual-core CPU.
The router comes permanently affixed to a metal stand that keeps it in a near-vertical orientation. The enclosure is fabricated from glossy white plastic and doesn't collect fingerprints, but it proved susceptible to scuffs and scratches. LEDs near the top front edge glow to indicate the status of power, the wireless network, the presence of a device connected to any of its four switch ports, Internet connectivity, the presence of a device connected to either of its USB ports, and WPS pairing.
This is a dual-band router operating an 802.11n network on the 2.4GHz band (maximum throughput 450Mbps) and an independent 802.11ac network on the 5GHz band (maximum throughput of 1300Mpbs). You can run a guest network on either band. A button on the right side toggles the Wi-Fi radios off and on, for those who like to button down their wireless networks when they're not around.
The Wi-Fi Protected Setup button is on the back of the router and--oddly enough--it serves double duty as the factory-reset button. This is an odd design choice since it could lead to an unintentional reset if held down too long (or if an inquisitive child discovers it). Reset buttons such as this are usually recessed and require an unbent paperclip to activate. This anomaly doesn't impact my final verdict, it's just worth noting.
If you care about parental controls, you'll find that the Archer C8 to be a very blunt instrument. Enable it and you can name a single PC as a "parental PC" (identified by its MAC address) that will have free access to the Internet. You must then enter the MAC addresses of every other PC that will operate on your network and create a white-list of sites those PCs are allowed to access. If a site isn't on that list, those PCs won't be able to go there.
The Archer C8's performance as an 802.11ac Wi-Fi router, paired with a 2x2 Asus USB-AC56 Wi-Fi adapter, was not at all impressive. In fact, it finished last or next to last in three of my four test locations.
TP-Link's router performed much better with a 3x3 802.11n client equipped with an Intel Centrino Ultimate-N 6300 Wi-Fi adapter operating on the 5GHz frequency band; in fact, it was faster at close range than any of the four routers I compared it to. It placed second when the client was in the kitchen, 20 feet from the router and separated by one wall.
But its performance fell off a cliff when I moved the client to my home theater, and it finished in last place when the client was in my home office (the room that's the farthest from the router).
The Archer C8's performance as a 2.4GHz 802.11n router was a decidedly mixed bag. While it eked out a first-place finish when the client was at close range, it finished third when I moved the client to my kitchen, and it couldn't maintain a connection at all when the client was in my home theater and in my office. If you're looking for a router to service legacy clients, give this one a pass.
Does it get a buy or pass recommendation
The TP-Link Archer C8 is one of the more basic dual-band 802.11ac routers I've reviewed, but it's priced accordingly. If you don't need a lot of features and don't have clients that you know are difficult to reach, there's little need to spend more cash for things you won't benefit from.
