Rivet Networks Killer Wireless-AC NIC 1420

General notes
This device seems to have been or will be sold w/ some Alienware CTO machines @ Dell in Europe and other non-US regions.
 * The full tag line w/ an Alienware order was Killer NIC 1420 802.11n/ac WiFi and Bluetooth 4.0 (SAF).

There is scant mention of this card anywhere on the net, but.. ... indicate this card was most likely the QCWB342 (WB342 reference design, QCA9862 based).
 * it's usage of the QCA988x/986x PCI ID per this driver (ak14w7 / ak14w7x [x64] named files)
 * probable half-sized Mini Card form factor, other options for the 2013 Alienware models look to be mPCIe based, M.2/NGFF expansion seems to be absent (though present in the newest models using the AC1525)
 * reference on a few far-east trading sites as the QCWB342 (auction.co.kr, taobao) - Lite-On manufacture

However, a M.2/NGFF reference design for the QCA9862 does also exist (NFA342) and also seems to be tersely labeled as a Killer Wireless 1420. With that noted, Both cards (.. and likely any other QCA988x/986x devices using 168c:003c PCI ID) will identify as a Killer AC 1420 from within Windows using QCA's Killer driver.
 * It doesn't appear to have passed through the FCC.
 * It's visible here @ cart100.com and taobao (both by the same seller).
 * The card is silkscreened with QUALCOMM ATHEROS, (QCABNFA1420A + Y5375 or NFA342 + 250-02460-030).
 * The card sold on Amazon (JP) is tersely labeled as a Killer™ Wirelss-N1420NGFF.
 * The back of the card is silkscreened with a Foxconn P/N of T77H476.

It's possible both WB342 / NFA342 reference design cards were sold as the Killer Wireless 1420, but it's not known with certainty.

Entry specific notes
The OUIs in this entry are certainly derived from T77H476 (or other Foxconn manufactured) units, however, it is not known where the PCI subsystem was sourced from.
