In an era when almost any smartphone can become a Wi-Fi hotspot in seconds, does the D-Link F518 5G Wi-Fi 6 AX1800 Mobile Hotspot still have a place in our kit?
After a recent working trip to Shanghai, I’ve found myself asking that question about a lot of technology: does this particular tool earn its place in the bag?
On paper, the D-Link F518 makes a strong case. It offers 5G NR connectivity, AX1800 Wi-Fi 6, an 8000mAh battery, support for up to 16 connected devices, USB-C PD input and output, and a claimed battery life of up to 16 hours.
That’s some serious capability for something you can take almost anywhere.
But it also weighs 274g.
When you’re already carrying a phone, laptop, charger and perhaps a tablet or eReader, another 274g isn’t insignificant. Especially when the phone already in your pocket can ostensibly do the same job.
So, the question isn’t really whether the D-Link F518 works.
It’s whether it’s useful enough to earn its place in the kit.
A Caveat: No eSIM Support Limits Its Travel Appeal
There is one limitation that immediately narrows the F518’s appeal as an international travel companion – there’s no eSIM support.
The F518 relies on a physical nano SIM, which isn’t necessarily a problem when you’re using it around your home country with an existing mobile broadband service.
But international travel is one of the situations where a dedicated 5G hotspot makes the most sense, and increasingly that’s also where eSIMs are most convenient.
My recent trip to China is a prime example. An eSIM was the practical option for staying connected, which means the F518 wouldn’t have made the cut for that particular trip.
That’s an unfortunate limitation for a device that’s otherwise designed to put portable 5G connectivity in your bag.
The D-Link F518 provides a dedicated 5G connection for laptops and other devices without relying on your phone’s hotspot.
The Other Caveat: 5G Roaming and International Band Compatibility
The F518 connects to both 4G LTE and 5G networks, so dropping outside 5G coverage doesn’t necessarily leave you disconnected.
However, seeing “5G” on the box doesn’t mean you can take the F518 anywhere in the world and expect it to work.
Mobile carriers around the world use different combinations of frequency bands, and the F518 itself is sold in regional variants with support for different bands.
The Australian model has fairly broad support across 4G LTE and 5G NR bands, but that doesn’t make it a universal hotspot. Before travelling, you’ll want to check that the F518 supports the bands used by your destination carrier.
In summary, international connectivity has three pieces to the jigsaw: a physical nano SIM, compatible frequency bands and a compatible carrier.
That’s not unique to the F518, but it’s something worth understanding before adding a dedicated mobile hotspot to your international travel kit.
D-Link F518 Performance: 5G and Wi-Fi 6 Tested
One thing to be aware of is that the F518 takes its time firing up. From pressing the power button, I found it took around a minute before the Wi-Fi network became available.
Speaking of Wi-Fi, the F518 broadcasts its 2.4GHz and 5GHz networks as separate SSIDs by default, letting you choose which band each device connects to.
For internet testing, I used the Optus SIM I have for hotspot testing. Running several speed tests through the F518 returned around 50Mbps download and 10Mbps upload.
Adding a second laptop didn’t make any appreciable difference to those results.
Those aren’t spectacular 5G numbers, but there are too many variables involved to pin that entirely on the F518. The Optus service, my particular SIM plan, network congestion and signal conditions can all influence the result.
I was more interested in what happened when I took the mobile network out of the equation.
I connected two Wi-Fi 6 computers to the F518’s 5GHz network and copied sixty 24MB photos – around 1.4GB in total – from one machine to the other.
Transfer speeds hovered around 50MB/s, or roughly 400Mbps.
That’s well below the theoretical 1200Mbps headline speed of the F518’s 5GHz Wi-Fi 6 connection, but those figures aren’t directly comparable. The AX1800 rating describes theoretical wireless link capacity, not the file-transfer speeds you’ll actually see between two devices.
In practice, sustaining around 400Mbps while transferring files between two wireless clients is a healthy result and, importantly, far beyond the speeds I was getting from the 5G internet connection itself.
For its primary purpose as a mobile hotspot, Wi-Fi performance certainly wasn’t the bottleneck.
No Display Is the F518’s Biggest Frustration
One aspect I find particularly annoying is the lack of a display. Any display.
D-Link has gone minimalist, using LEDs to indicate internet connectivity, 4G/5G signal, Wi-Fi and battery status.
Yes, it’s kind of pretty, but it also leaves me guessing a little too often.
On a device designed to manage a mobile data connection, an LCD could provide far more useful information at a glance: signal strength, network type, battery percentage, connected devices and perhaps even data usage.
I don’t know about you, but I would want to know how many devices are leeching off my F518 at a glance, in case I have picked up a hitchhiker.
You can get that information, but you need to connect a phone, tablet or laptop to the F518 and open its browser-based management interface. From there, you can see connected devices, traffic statistics and some more detail about what’s going on with your hotspot.
It works, but reaching for another device to find information that could have been shown on the F518 itself feels like an unnecessary extra step – particularly on a dedicated mobile hotspot that certainly is not budget-priced.
I’m also the type who wants to know the actual state of the battery, especially when a green battery icon could mean I’m sitting at 95% or 21%. For the F518, it goes red at 20%. At 5%, it’s blinking red and we’re officially in dire straits.
More frustratingly, you can’t even turn to the browser-based management interface for an actual battery percentage. You’re stuck with the LED’s fairly broad interpretation of how much juice you have left.
That also makes D-Link’s claim of up to 16 hours of battery life difficult to test with any precision. I ran the F518 for a good few hours and it remained solid, but without an actual battery percentage to work with, testing how closely it gets to that 16-hour figure becomes an all-or-nothing affair.
D-Link F518 Review: Final Verdict
The D-Link F518 is a solid performer, but the lack of onboard information makes using it more complicated than it needs to be.
Battery life is good, and the ability to double as a power bank is genuinely handy for families – although you kind of want the kids’ devices to run down so they finally get off the screen.
The bigger question is the one I started with: does it earn its place in the kit?
For someone regularly connecting multiple devices, working remotely or wanting to preserve their phone’s battery rather than hammering it with hotspot duties, there’s a good argument that it does. Having a dedicated 5G connection you can switch on, throw in the bag and share has advantages that phone tethering can’t entirely replicate.
But the F518 isn’t an automatic addition to everyone’s travel bag. At 274g, it’s another device to carry, there’s no eSIM support, international compatibility requires some homework, and the lack of a display feels like a strange omission on a mobile hotspot that is commanding a decent dollar value. In all honestly I found the browser page to be pretty basic in functionality.
Ultimately, the D-Link F518 5G Wi-Fi 6 AX1800 Mobile Hotspot does its core job well. At RRP A$449.95 (although currently discounted to A$379.95), the question is whether you need that job done often enough to justify carrying, and paying for, another piece of kit.
DRN would like to thank D-Link for providing the review unit.
