Hi - For the new computer I just built, I bought a D-Link DWA-582 802.11ac PCIe adapter. It's based on the Realtek RTL8812AE chipset. Does anyone know the particular magic to get these going, please?
From the start on Ubuntu Gnome, the card would work for about 15 minutes, then disassociate itself from the router. It might occasionally spring back to life for a few minutes, but there didn't seem to be anything special I was doing to get it reconnected.
I've updated the firmware blob(s) from the Realtek linux maintainer's site. Older posts about this chipset say it's a power management problem, but the newest firmware supposedly fixes this. Should I have bought a different card? What 802.11ac cards work for people here? I'm not super keen on drilling holes in the floor to snake an ethernet cable up from the basement. cheers, Stewart
