2018 Surface Pro with Marvell AVASTAR WiFi integrated - really mediocre and weak performance that didn't work well even with excellent WiFi. Video quality freezes or drops out, websites load as fast as a dial-up connection, and downloads seem like it's been six years. (In Chrome, Apps and Edge.) This EUDP wireless USB adapter solved this problem. You will be given a Realtek RTL8811AU Wireless LAN 802.11ac for which you can either download the driver (small instruction CD or go to the website) or let Win10 install the driver. Enter security information. Consider turning off any other Wi-Fi radios on the device that you won't be using, and it's easy to turn them back on when needed. We're pretty much on the same page when comparing throughput to Surface's built-in Marvell, but the actual performance results are video streaming. Issues and quality are now excellent, loading has improved, web pages load quickly and as expected. No dropouts or problems at all on 5GHz or 2.4.
