Realtek RTL8111 driver is clearly loaded and Ethernet card appears functional.

What's not working of course is the Qualcomm Atheros QCA6174 WLAN card; that's unsupported under OS X/macOS and will need to be replaced.

Did you verify your cable was Ok? LAN card set to auto-neg or some fixed 10/100/1000Mbps settings? MAC address of your card sure is listed in IOReg.

 

Or maybe version 2.3.0 of the kext is inadequate for Big Sur. Try version v2.4.0 posted by Mieze on her Github repo and at InsanelyMac. Also check the latest info posted on the dedicated RTL8111 thread at IM. That's where Mieze discusses her development work on the driver and where people report on their experiments. If v2.3.0 or v2.4.0 do not work, try the previous versions; I've seen people reporting issues such as yours with version 2.3.0/2.4.0. You'd also read this in the comments left for this driver posted in the Download->kexts->LAN & Wireless section at IM.

here's 2 versions for RealtekRTL8111

2.2 and 2.4

 

As for Wireless, your card is not supported as Hervé mentioned, you'll need to get it physically replaced

See here for a list of supported M.2 wireless device
