AI seems to be everywhere lately, and that includes the world of home networking: D-Link’s latest “smart router” proudly wears its AI credentials on its sleeve. As we’ll see, this is definitely a case where the buzzword oversells the reality, but if the R32 is short on smarts it makes up for that in value. As we went to press, it cost only £73 inc. VAT on Amazon, making it one of the cheapest Wi-Fi 6 routers around.
The Eagle Pro AI R32 is the successor to last year’s Eagle Pro AI R15, which was similarly cheap and looked almost identical. The main difference between the two is what you might guess from the name: the new model is just over twice as fast as the old one, in terms of wireless bandwidth. It supports connections of up to 800Mbits/sec on the 2.4GHz band, while the 5GHz radio goes up to a maximum speed of 2.4Gbits/sec. There’s also more wired bandwidth available, as the R32 gains an extra Ethernet socket at the back, to make up a full quartet of gigabit LAN ports.
Aside from those sockets there’s not much to see: no USB, no multi-gig connectors and only four LEDs on the front to show you the status of your power, internet and Wi-Fi. But that’s fine – do you really need more?
Getting set up is delightfully simple, via either D-Link’s Eagle Pro AI mobile app or the router’s built-in web management interface. There isn’t a huge amount to configure, but D-Link builds in more features than you might expect from such a cheap device. For example, a basic quality-of-service tool lets you assign different priority levels to individual clients, and you can also enforce internet access schedules and time limits for kids’ devices.
For added security, you can flick a switch to replace your ISP’s default DNS with secure DNS from Google or Cloudflare, offering protection from hijacking attacks. There’s a basic configurable firewall, too, and an unexpected treat is an incoming VPN server, plus integrations with no-ip. com and dyndns.com to provide easy external access to your home network.
If you want to use the R32 as a Wi-Fi extender for an existing network you can alternatively switch it into bridge mode – or use mesh mode to connect two or more units together and spread your wireless signal over a wider area. Remember, though, that beaming mesh traffic back and forth between wireless stations eats into the bandwidth available for your devices, so you’re trading off performance for range.
Finally, let’s not forget the R32’s promised “AI” capabilities. In practice, this simply means the router periodically checks its Wi-Fi channels and tunes its beamforming settings to get the best connection to your clients. These are welcome features, to be sure, but it’s a pretty egregious overreach of the term AI.
Never mind; you’re probably not buying a £73 router in the expectation of a world-class feature suite. The real question is, how does the thing perform? And the answer is very well – at close range. I tested the R32 by hooking up a NAS drive to one of its Ethernet ports, then hawking a laptop around my home and measuring upload and download speeds as I copied a set of 100MB test files to and from the NAS.
Initial findings were very positive. I was delighted to see an average download speed of 85.5MB/sec in the same room as the router, and when I moved downstairs to the living-room I still got a speedy 72.9MB/sec.
Unfortunately, the R32’s four little antennas aren’t beefy enough to keep up that sort of performance all through my home. Speeds fell to 25.8MB/sec in the kitchen and 21.1MB/sec in the bedroom; that’s still ample bandwidth for typical internet tasks – a 4K HDR video stream requires about 4MB/sec – but it’s still a pretty precipitous drop.
Unsurprisingly, the R32 fared worst in the bathroom at the back of the house. Here I could clearly see my file transfers momentarily hang and resume several times during my tests, so while the eventual average download speed of 5.5MB/sec might sound fine for web browsing or cloud syncing, it’s patchy: I’d rather not rely on it for video calls or online gaming.
Does this mean you should steer clear of the R32? It really depends on what you want from a router. Those who need reliable wide-area coverage should consider spending the extra £50 on the Asus RT-AX59U: as well as more stable long-range coverage, it will give you a broader range of software features. However, if you just want basic connectivity across a few rooms, the R32 will fit the bill very nicely – there’s no need to pay more.
