The old card, a Broadcom BCM943228HMB, works fine; both Wi-Fi and Bluetooth are detected. But the new card, an AzureWave AW-CB160H (Broadcom BCM94360HMB) does not; only Wi-Fi works (in macOS), and Bluetooth isn't detected at all.
Note that I've been doing all this testing on a Pop!_OS live USB.
I've confirmed that the WLAN port on the X131e has both PCIe and USB lanes by looking at the schematics. (The WWAN port has SATA and USB lanes, for reference.)
I've tried taping over both pins 5 and 51 (this made BT work on my Latitude E6410), just pin 51, and no pins at all on the AW-CB160H, but it doesn't seem to make a difference.
Here's the output of
Code: Select all
lspci -nnk | grep -iA3 net; lsusb; sudo dmesg | egrep -i 'blue|firm'
I could try a Fenvi BCM94360NG with a M.2 to Mini PCIe adapter I accidentally bought, but I doubt it would work since the only port long enough to fit it (WWAN) doesn't have PCIe lanes.
Yes, Bluetooth is enabled in BIOS. I've tried with Bluetooth disabled, too, but it didn't make a difference.
