TP-Link Wi-Fi Dongle AC1300 Wireless Dual Review UK 2026

You've got a desktop with no Wi-Fi, or a laptop that refuses to pick up a signal from the router two rooms over, and you just want the thing sorted without spending a fortune or faffing about with powerline adapters. That's exactly the gap the TP-Link Archer T4U is aimed at. It's a USB Wi-Fi adapter, dual band, 802.11ac (Wi-Fi 5), and it plugs into a spare USB 3.0 port to give a wired-only machine wireless connectivity, or to replace a rubbish built-in adapter that keeps dropping out.

The B01N4T93MM sits in budget territory, and at that price you're not getting Wi-Fi 6 or any of the fancy stuff. But here's the thing: for a lot of people, that doesn't matter. If your router is already Wi-Fi 5, or your machine is older, you don't need a Wi-Fi 6 adapter. What you need is something that actually connects reliably, doesn't need a driver hunt every time Windows updates, and gives you enough speed to stream and browse without buffering. Whether the Archer T4U delivers that is what this is actually about.

With 901 owner reviews averaging ★★★★☆ (4.3), there's clearly something going right here. But averages hide patterns, and the interesting stuff is always in the detail. So here's what the specs say, what owners consistently report, and how it stacks up against the alternatives at this price.

The headline speed figure is 1300Mbps, which TP-Link breaks down as 867Mbps on 5GHz and 400Mbps on 2.4GHz. As always with these numbers, treat them as theoretical maximums under perfect conditions, not what you'll see day to day. The real-world throughput you get depends on your router, your distance from it, how many other devices are competing, and the quality of your ISP connection. But the spec does tell you something useful: this adapter can handle fast connections without being the bottleneck, which is what matters.

The USB 3.0 connection matters. TP-Link lists this as up to 10x faster than USB 2.0, and that matters because older USB Wi-Fi adapters on USB 2.0 ports can actually throttle the connection, especially on the 5GHz band where throughput is higher. USB 3.0 removes that limitation. The adapter also has external high-gain antennas, which are a genuine improvement over the flat dongle style, because antenna size and placement directly affect signal quality and range.

Owner reports are broadly positive on range. People consistently mention being able to connect from rooms where their previous adapter (or built-in card) struggled, and the 5GHz band in particular gets praise for staying connected at distances that cheaper single-band adapters can't manage. The 2.4GHz band, as you'd expect from the physics, reaches further and through more walls, though at lower speeds. In a typical UK semi-detached or terraced house, owners report solid connectivity from most rooms. The box coverage figures are always best-case, measured line-of-sight in an empty room, and your actual experience will depend on how many walls and floors are between you and the router.

One thing from owner feedback: the adapter's physical position matters quite a bit. Because it's plugged directly into a PC, it can end up tucked under a desk or behind a case, which blocks the antennas. A fair number of owners mention using the USB extension cable (if one is included in the box, or a cheap one from elsewhere) to position the adapter somewhere with a clearer line to the router. That's not a criticism of the hardware exactly, it's just the reality of a USB adapter versus a proper internal card or a router with antennas on top of a shelf. before you buy.

The USB 3.0 connection is genuinely relevant here. USB 2.0 has a practical bandwidth ceiling of around 480Mbps, which sounds like plenty until you're trying to push 5GHz Wi-Fi 5 speeds through it. USB 3.0's much higher bandwidth means the interface itself doesn't limit what the adapter can deliver. Owners using this on fast broadband connections report speeds that are consistent with what their router can deliver at that distance, which is the right answer. You want the adapter to be transparent, not the limiting factor.

Under load, meaning multiple tabs, a video call, and something downloading in the background, owner reports are generally good. The adapter handles the kind of multitasking a single user puts through it without obvious degradation. It's not designed for a household of heavy users all sharing through one adapter (that's not what it's for), but for a single PC or laptop getting proper wireless connectivity, the sustained performance holds up well according to the people who've actually used it day to day. The 4.3 average across 902 suggests the majority aren't hitting significant performance problems.

Where this becomes relevant is if you have a device that can't connect to Wi-Fi at all, or connects poorly via a built-in card, and you want to give it proper wireless access to a network that already exists. A desktop PC with no wireless card, a laptop with a failed internal adapter, or an older machine that only has a 2.4GHz single-band card are all good candidates. In those cases, the Archer T4U is the right tool. It plugs in, it connects, and your machine gets dual-band Wi-Fi without opening the case or buying a PCIe card.

The closest thing to a backhaul consideration here is the USB 3.0 connection between the adapter and the host machine. That's the data path between the wireless radio and your PC, and as covered above, USB 3.0 is fast enough that it won't limit you. If you're on a machine that only has USB 2.0 ports (genuinely old kit), you'd see a ceiling on 5GHz throughput. Most machines made in the last decade have USB 3.0, so this shouldn't be an issue in practice, but it's your machine's spec if you're not sure.

Owner reports on stability are mostly positive. The most common complaint in the negative reviews is driver-related rather than hardware, which is a recurring theme with USB Wi-Fi adapters generally. Windows updates occasionally cause driver conflicts, and a small number of owners report needing to reinstall or update drivers after a major Windows update. TP-Link does publish drivers on their support pages, so it's not a dead end, but it's something to be aware of. It's not a unique problem to this adapter, it's a USB adapter thing across the board.

For a single user's machine, the adapter handles concurrent demands fine. Streaming video while downloading in the background, gaming while something updates, the kind of multi-tasking a normal user does on one machine. That's what it's designed for and owners confirm it handles it without drama. If you're imagining running a hotspot through this and sharing the connection to multiple devices, that's technically possible in some configurations but not what this is built for, and you'd be better served by a proper router or access point.

Here's the honest answer on future-proofing: if your router is already Wi-Fi 5, a Wi-Fi 6 adapter won't give you anything extra. The connection is limited by the slower of the two devices. If you've got an ISP-supplied router from a few years back, it's almost certainly Wi-Fi 5 or older, and buying a Wi-Fi 6 adapter to go with it is pointless. The Archer T4U is a sensible match for a Wi-Fi 5 router, and it'll connect to Wi-Fi 6 routers at Wi-Fi 5 speeds, which is still perfectly usable. If you've recently upgraded to a Wi-Fi 6 router and you want to get proper Wi-Fi 6 speeds on a machine, you'd want a Wi-Fi 6 adapter instead. But for most people with mid-range or older routers, Wi-Fi 5 is fine.

The Linux support listed in the spec is worth a mention because it's genuinely useful and not universal among budget USB adapters. Support for Linux kernel versions 2.6.24 through 4.7 is listed, which covers a lot of common distributions. If you're running Linux on a desktop and need wireless, the fact that TP-Link explicitly lists Linux compatibility narrows down the driver headache considerably. That said, if you're on a very recent kernel version, check the TP-Link support page for the latest driver status before buying.

What the Archer T4U does offer beyond basic connectivity is dual-band selection. You can choose whether to connect on 2.4GHz or 5GHz depending on your situation. If you're close to the router and want maximum speed, 5GHz. If you're further away or have thick walls between you and the router, 2.4GHz might hold a more stable connection even if the throughput is lower. Some adapters handle band selection automatically, others let you choose manually. Either way, having both bands available is a genuine advantage over single-band adapters that are stuck on 2.4GHz.

The high-gain antenna design is probably the most significant feature after the dual-band support. A lot of budget USB adapters use tiny internal antennas that look neat but sacrifice performance. The external antennas on the T4U improve both signal strength and reception sensitivity, which translates to better range and more stable connections at distance. It's not glamorous, but it's the kind of practical engineering decision that makes a real difference in day-to-day use, and it's one of the things owners specifically call out positively in reviews.

The driver situation on Windows is generally fine. Windows 10 and 11 compatibility is listed in the spec, and most owners report it working without needing to manually hunt for drivers. A subset of owners mention issues after Windows updates, which is a known frustration with USB Wi-Fi adapters generally. The fix is usually downloading the latest driver from TP-Link's support page, which is straightforward enough, but it's a bit of a faff if it happens to you at an inconvenient moment.

Linux driver support is more variable and depends heavily on your kernel version and distribution. The spec lists support for Linux 2.6.24 to 4.7, but the Linux community has done a lot of work on drivers for TP-Link chips beyond that range. If you're on a recent Ubuntu LTS or similar, it's current driver availability before committing. TP-Link's support page is the right starting point. The broader point is that TP-Link is one of the better budget brands for actually maintaining driver support over time, which counts for something.

TP-Link does provide a utility application if you want it, which can help with band selection and connection management. But most owners don't bother with it and just use the built-in Windows network tools. On Linux, setup is more involved and depends on your distribution and kernel version, but the TP-Link support documentation covers the process, and there's a decent amount of community knowledge around this specific chipset.

The physical setup is worth thinking about. The adapter is larger than a nano dongle because of the antennas, which means it sticks out from your USB port noticeably. On a desktop tower this is usually fine. On a laptop it's a bit more awkward, especially if you're moving the laptop around. The USB 3.0 connection means it'll work in any USB 3.0 port, and backwards compatibility means it'll physically plug into USB 2.0 ports too (just with the speed ceiling mentioned earlier). If the adapter ends up in an awkward position, a short USB extension cable sorts it out.

There are no Ethernet ports, no WAN ports, no LAN ports. This is a wireless adapter, not a router. If you need wired connectivity, that's a separate product. What you do get is a USB 3.0 connection that's fast enough to handle the full throughput the wireless radio can deliver on either band, which is the right answer for this category of device.

Compatibility with the host machine's USB ports is worth a quick check. USB 3.0 ports are typically marked with a blue colour on the inside of the port, or labelled SS (SuperSpeed). The adapter will physically fit into USB 2.0 ports too, but you'll get the USB 2.0 bandwidth ceiling on 5GHz connections. For 2.4GHz use at moderate speeds, USB 2.0 is fine. For getting the most out of the 5GHz band, USB 3.0 is the right port to use. Most machines made after about 2012 have at least one USB 3.0 port, so this is rarely a problem in practice.

There's also the question of whether to go USB adapter at all versus a PCIe internal card. If you've got a desktop PC and you're comfortable opening the case, a PCIe Wi-Fi card typically offers better performance and more stable drivers than a USB adapter, often at a similar price. Cards like the TP-Link Archer TX50E (Wi-Fi 6) are if you want to future-proof at the same time. But if you don't want to open the case, or you're adding Wi-Fi to a laptop with a failed internal card, the USB adapter is the right approach.

Against the competition in the USB adapter space specifically, the Archer T4U's combination of dual-band support, USB 3.0, and external high-gain antennas puts it in a strong position. Most of what it's competing against either drops to USB 2.0, lacks external antennas, or is single-band. At this price, it's hard to find a USB adapter that matches all three of those specs.

The honest caveats are these: it's Wi-Fi 5, not Wi-Fi 6, so if you've got a shiny new Wi-Fi 6 router and you want to actually use the newer standard, you'd want a Wi-Fi 6 adapter. Driver management after Windows updates is a minor but real annoyance that affects USB adapters as a category, not just this one. And if you've got a desktop and you're happy opening the case, a PCIe internal Wi-Fi card will generally give you better and more stable performance for a similar outlay.

But if you want a USB adapter that's a step above the cheap nano dongles, that gives you real dual-band access with proper antennas and a USB 3.0 connection that won't bottleneck you, the Archer T4U is the right pick at this price. If you genuinely just need basic 2.4GHz connectivity and you're always close to the router, the cheaper Archer T3U nano will save you a few quid and do the job. But if range and 5GHz performance matter, the T4U is the one to go for.

Editorial score: 7.5 out of 10. Good hardware, sensible specs, well-supported. Loses marks only because it's Wi-Fi 5 in a world moving to Wi-Fi 6, and because USB adapters as a category have inherent driver management overhead that a PCIe card avoids.
