WiFi, Bluetooth, USB ports & headphone jack not working on right side

After I dropped my mac to the floor (not very heavy drop and also inside the bag), I lost the WiFi, Bluetooth, most of the USB ports (those on the right side) and the jack sound is distorted speaker sound is OK. Maybe others outputs are damaged as well haven’t tested and never use them either so I haven’t bothered.

I’ve tried PRAM resetting, opened the chassis and removed and inserted the WiFi card, pushed connectors that might have been loose, but so far no success.

I have thought about buying a new WiFi card, but I suspecting thats not the core issue here. I was then wondering if someone knew what inside the Mac was controlling these components, if it’s an easy replaceable card I can fix it, but if its down to the motherboard I might be throwing in the towel on this one.

Any help would be greatly appreciated!

Kind regards
