[Google Pixel 3 XL Questions & Answers] Snorp09:
Last night my Wifi adapter in my Pixel randomly stopped working. I'm not actually certain when it happened, but I know it was happening after I flashed a Engineering AOSP build.

I've flashed the latest factory image, but it hasn't fixed it. Do I need to RMA it? Or is there maybe a fix I can preform at home?

Here's my logcat about the Wifi. It appears to have something to do with the driver. Bluetooth is working. I'm not sure if they share the chip on this device.
