Hi there!
I have this WiFi card in my PC. This router is what I'm using. I'll post the rest of my PC details at the end of the post.
I'm trying to get Wake on Wireless LAN (WoWLAN) working and have been for about two months now. I've done a lot of searching and made a lot of settings changes. On the adapter itself, I've set it to not turn off to save power and to allow the card to wake from sleep via magic packet. I've also ensured my power plan settings don't interfere with the feature. I've also allowed it via BIOS.
I searched and found this thread which basically explains my same situation, right down to using a WiFi 6 capable card.
What seems to be happening, despite my best efforts, is that the WiFi card is powering down as a part of the sleep process. Watching the active connections on my router shows my PC drop off as soon as it enters sleep mode. Obviously, if the PC isn't showing on the network, a magic packet will never make it to the destination. Any ideas what I could be missing?
