How to troubleshoot if your computer goes to a blue screen when installing TP-Link wireless adapter 01-13-2021 120756 How to Setup an Ad Hoc Wireless Network with Windows Built-in Utility (Windows XP) 09-27-2019 190561 All of these adapters are compatible with Windows PCs and several also work with Linux. None of them have official drivers for macOS versions later than 10.15 (and some don't even have that), because the chipset vendors don't bother to support macOS. An enterprising independent programmer has developed macOS 11 and macOS 12 drivers for many of the adapters we've reviewed, but you should yse these at your own risk. Adapters also likely won't work with other home electronics, as they require the right drivers.

Your laptop probably supports 802.11ac—most laptops released since 2013 do—but if yours doesn't, that's another reason to get an adapter. 802.11ac is a massive improvement over the previous 802.11n and can give you a boost even without the benefits of the bigger antenna on an adapter. When I tested the D-Link Wi-Fi 6 adapter more recently, I could do so in a more controlled environment. As such, I was able to compare speeds between that adapter, the TP-Link Archer T9UH, and the TP-Link Archer T4U Plus. Those results are in the full D-Link DWA-X1850 review. Problems you may come across during the driver installation of the TP-Link wireless adapter 10-24-2023 718850What should I do when the driver for my adapter is not allowed on my windows computer? 06-29-2022 133912 What should I do if the TP-Link network adapter is not working properly in my computer? 12-02-2022 442812 The best way to improve your Wi-Fi signal is to switch from a single router to a mesh network system, but mesh systems can be expensive. Wi-Fi extenders are another option, even though they can create interference and add latency; I wasn't thrilled when I tried one. If you just need to eke a little bit more Wi-Fi out to one laptop or desktop, a USB adapter is a much cheaper alternative. Wi-Fi 6 promises to bring better speeds, better range, and less interference to business and home networks, but so far, that experience hasn't materialized in real-world environments. Numbers are based on testing conducted by the USB-IF and your computers are required to also support USB 3.0
