Speeds are excellent on 5GHz when connected to a suitable Wi-Fi 5 router, but there’s not much point in spending this much if your laptop already has Wi-Fi 5 (802.11ac) Wi-Fi, or you’re going to use it so far away from your router that it only ever runs on the 2.4GHz band, where performance is much less impressive.įor similar money to TP-Link’s T9UH, D-Link’s Wi-Fi 6 dongle offers slightly slower AX1800 speeds (as opposed to AC1900) but the benefits of Wi-Fi 6 such as MU-MIMO and OFDMA.

The dock’s 3m cable means you can position the adapter in the ideal place, which is handy if existing Wi-Fi connectivity is spotty in your location. The T9UH also comes with a dock that allows it to be connected further away from your PC or laptop. The design is for the dual-band antennas (2.4GHz 600Mb/s and 5GHz 1300Mb/s) with 802.11ac AC1900 support.Īs is standard now with higher-end adapters, TP-Link supports beamforming which delivers more consistent performance, ideal for streaming HD and 4K media content, and USB 3.0 is required because of the higher throughput, so you’ll get the best speeds if you connect it to a USB 3 port, not USB 2. Unlike the multi-appendage approach of the Asus USB-AC68, this has a hinged edge to the body that can almost fold in half. On a practical note, the Archer T9UH features a fold-out design which opens to around 150mm long. Not everyone has a Wi-Fi 6 router yet, nor enough Wi-Fi 6 devices to truly benefit from some of the clever tech that the standard offers. True, those are theoretical speeds, but the point is, Wi-Fi 5 dongles can offer just as fast real-world speeds as Wi-Fi 6 in many homes. It might not support the latest Wi-Fi 6 standard but that doesn’t really count against it because, in the topsy-turvy world of Wi-Fi, it actually offers faster speeds than D-Link’s Wi-Fi 6 adapter. For most people, the T9UH is the best Wi-Fi upgrade (or add-on if your PC doesn’t have Wi-Fi at all).
