TP-Link AC600 USB WiFi Adapter for PC (Archer T2U Plus)- Wireless Network Adapter for Desktop with 2.4GHz, 5GHz High Gain Dual Band 5dBi Antenna, Supports Win11/10/8.1/8/7/XP, Mac OS 10.9-10.14, Black

I have had this desktop computer for a while now and it did not have an Internet capability except using an ethernet cable which I don’t currently have the location I’m using. Just as described, this was plugged and play. The unit itself contains all the drivers you need. It was up and running very easily and seems to be working well.

⭐️⭐️⭐️⭐️⭐️ Fast connection and easy setup! This WiFi adapter works perfectly! Setup was super quick — just plugged it in and it connected right away. The signal is strong and stable, even in the rooms farthest from my router. My internet speed is noticeably faster now, and I haven’t had any drops or lag. Great value for the price and definitely worth it if you need to boost your connection.

Works just like the older version I have. Easy to install and use.

Solid WiFi Boost with a Few Caveats I’ve been using the TP-Link Archer T2U Plus USB WiFi Adapter to give an older desktop some wireless capability, and overall, it does the job well. Setup was quick—plugging it in and letting Windows handle the driver worked fine for me, though TP-Link’s website offers updated drivers if needed. Performance is solid for everyday use. On the 5GHz band, speeds are noticeably faster and more stable than 2.4GHz, which is expected. Streaming video and browsing felt smooth, and I had no trouble with Zoom calls. The long, high-gain antenna makes a real difference for range—signal strength stayed strong in parts of the house where built-in laptop WiFi usually dips. That said, this isn’t the most compact option. The antenna is large and sticks out quite a bit, so it’s not ideal if you plan to move the computer around or use it with a laptop on the go. Also worth noting: while it supports Mac, it only works up through macOS Mojave (10.14), so newer Mac users are out of luck. Bottom line: A reliable and affordable way to add or upgrade WiFi on a desktop, especially if you need stronger range. Just keep in mind its bulky design and limited MacOS compatibility.

I have purchased this particular adapter multiple times for multiple PCs. For the most part, I honestly really like this little adapter. It doesn't need specific drivers for Windows 10/11 (Plug & Play), is USB 2.0 (no need to use one of my high speed ports), and does pretty well range and bandwidth wise. As my current internet setup does not break 500mbps up/down, I'm not too worried about losing any speed with this 2.0 adapter. My most recent purchase has a slightly more niche purpose: it is used for one of my gaming & streaming setups (in particular Stepmania; a Dance Dance Revolution clone). I decided to use a 10 foot USB 2.0 extension cable to run my adapter up towards the top of a doorframe, closer to my gateway. This ensures better streaming capability and signal. The game itself does use the adapter for doing check-ins so the game plays properly with this setup as well. I haven't had any issue with heat generation on this adapter. It might get a little warm but nothing worrying. The only issue I have is the adapter is a little chunky size-wise, and it doesn't feel like it wants to sit flush or snug in the USB port. For peace of mind, I do have some packaging tape holding the adapter in place connected to the extension port. Overall, I really do like this version compared to the USB 3.0 versions that are more common in the market today.

Works amazing and the Internet speed is quick. Worth the money and will buy again if needed

I purchased the TP-Link Archer T2U Plus USB WiFi adapter hoping it would solve a specific issue: my older laptop’s onboard WiFi struggles to detect my work network, even though it connects just fine at home and to public networks. Initially, this adapter seemed like the answer—but it quickly became clear I had traded one set of problems for another, much worse one. The Core Issue: Intermittent Disconnections This seems to be a widespread problem among USB WiFi adapters, especially those using Realtek chipsets (which includes this one). The connection will randomly lag, drop, and completely fail to reconnect. The only fix? Yank the adapter out of the USB port and plug it back in, essentially giving it a hard reboot. Sometimes it reconnects; sometimes it doesn’t. In extreme cases, it disconnects again within seconds. This isn’t a one-off fluke—I’ve experienced it consistently, and it matches what countless others have reported. Not Just This Adapter—Likely a Realtek Chipset Problem After some digging, it appears Realtek-based adapters are notorious for poor driver support, unstable performance, and strange power-related issues. Frustratingly, most affordable adapters on the market use Realtek chips, and it’s difficult to find ones that don’t—there's no central list of alternatives, and product pages rarely specify the chipset used. Bigger Problems: USB Port Glitches and System Instability It didn’t stop with network drops. One morning, I booted up my PC and realized multiple USB ports had stopped functioning. Devices like my speakers wouldn’t work when plugged into these “dead” ports—unless they were already connected when the PC powered on. Even weirder, unplugging the TP-Link adapter would instantly bring those ports back to life. Plug the adapter back in, and things might work—until the next reboot. This wasn’t isolated to my machine either. My wife’s PC experienced an even worse issue: the adapter caused power draw problems during Windows boot, leaving the M.2 SSD underpowered and triggering boot failures. Booting from Linux confirmed the adapter was acting strangely, with system utilities flagging it as a misbehaving USB device. Poor Setup Experience and Misleading Instructions Setup was frustrating too. The adapter couldn’t even detect the specific network I bought it for, although it could see every other nearby network. It also created a TP-Link-branded network that demanded a password or security key that’s never mentioned in the instructions. The manual says to use the WPS button on your router, but guess what—Spectrum routers don’t have one. Dead end. No Real Support from TP-Link Trying to get help from TP-Link is an exercise in futility. Their customer service is almost nonexistent, and their online resources are focused mainly on their routers and modems—not adapters. You’re far better off looking up YouTube videos and Reddit threads. Just don’t expect any kind of direct support. Bottom Line: Don’t Waste Your Time or Money This product, and frankly most USB WiFi adapters using Realtek chipsets, are unreliable at best and potentially damaging at worst. If you’re lucky, you’ll get a week or two of decent performance before the headaches begin. In my case, and in my wife’s, these adapters caused serious system-level problems. I’ll be returning both units and requesting a refund through Amazon—which, thankfully, is usually pretty hassle-free. It’s sad, but I’ve come to view these devices as temporary fixes with a built-in expiration date. You might get lucky. Or, more likely, you’ll end up with a defective product that quietly disrupts your entire system. Recommendation: Avoid this adapter and any USB WiFi device using Realtek chipsets. It’s not worth the instability, power issues, or the time spent troubleshooting.

Bought a gaming computer and found out it didn’t have Wi-Fi. Found this based on great feedback and price. It was easy to install, and has great range! No issues on download speeds.
