Okay, so i have a D-Link AC1200 DWA-582 (Realtek RTL8812AE) Wi-Fi card, which ive had problems with for the last year or so. Because my room is pretty far away from the router, i have a sky dual-band booster (repeater) box, which covers the black spot i have. All my other devices work fine with this, however my D-Link card only connects when it feels like it. When it does work its amazingly fast which is why i havent bothered buying another card yet. I have already updated all drivers and tried the various commands in command prompt but nothings working. Does anyone have any suggestions, i have been trying to fix this for months now but keep giving up as i cant find the problem
