Curious what replacement card you went with. I know the WiFi/BT are combined, Bluetooth headphones cutting out last night for no reason at all and the thought came around again to flip a replacement in.
Nice to meet another used hardware buyer. I think the total cost of my laptops over the past 10 years equates to roughly the price of a single new high spec Macbook, and that's with repeat replacements due to damage / spills / etc.
I went with an Intel 7260HMW BN for $20. Dual band with Bluetooth 4.0.
USB 3 can trash your WiFi/BT spectrum as many device manufactures provide inadequate shielding. I got some foil tape and carefully lined the inside of an external drive enclosure and fixed some intermittent WiFi issues. FCC should scrutinize USB devices more, I thinks. Probably wack-a-mole though.
The PCIe versions of those cards are widely known to experience frequent microcode hangs (which can also hang your entire machine) depending on "some circumstances" (allegedly linked to 5 GHz 802.11n or something).
