It looks like the wifi hardware is soldered on the board for this machine. Any fixes that don’t require replacing the logic board? I’m thinking a USB dongle might be the way to go here, are there any that can utilize the Apple wifi software?

Can you give us a bit more here. What is happing did the Bluetooth and/or WiFi stop working or are you trying to connect to a new WiFi Access Point (AP) and it won’t connect?

At this point you have only one means of connection via a USB-C/TB to Ethernet dongle or hub unit. I think its time to open the system up and inspect things MacBook Pro 13" Function Keys 2017 Lower Case Replacement
