In July, I installed five XG-C100C V2 rev 3 into my work PCs.
All of them have intermittent (monthly maybe) problems with disappearing on reboot or cold boot. By disappearing I mean that they either no longer appear in device manager at all (not even with an exclamation point). This behavior is also mentioned in a post HERE
The only thing that will restore the function of the cards is draining the flea power from the systems when this happens. Doing this will return the card to “ASUS XG-C100C 10G PCI-E Network Adapter” in device manager.
Another way these cards cease functioning is they’ll regress to “Marvell Antigua Engineering Sample” in device manager with a driver loaded but the NIC doesn’t pass traffic. When this happens…again the only thing that will restore the function of the cards is draining the flea power from the systems and the cards will return to “ASUS XG-C100C 10G PCI-E Network Adapter” in device manager.HERE
is another person on Reddit with the exact same “engineering sample” problem with this ASUS card.
Perhaps the nature of both card detection problems is related.
All five of my PCs are running the latest driver 126.96.36.199 with fully updated Windows 10 Enterprise. The problem also occurred with Asus driver 188.8.131.52. All cards are running in Dell Workstations (Intel C610 chipset) with latest BIOS. I’ve tried all possible PCIe slots. PCIe gen 2 and PCIe gen 3. All the cards are ROM 1.0.1. The only way I was able to determine the ROM was by attempting to boot the NIC because the Marvell flash tool reports the FW as 0.0.0.
I have not disabled any of the advanced driver level power saving features of these cards.
Like this post HERE
, I tried to see if the Marvell diag tool would read the firmware correctly and allow force flashing like other folks have done with rev 2 or earlier cards. Sadly, the diag tool just returns “no devices found even when using the K switch and selecting to install the driver. Selecting to install the driver just returns “no devices to install driver with.”
These same workstations haven’t had PCIe card detection issues with any other PCIe cards including the following (USB 3 controllers, USB C controllers, Realtek NICs, Intel NICs, Emulex NICs, Trendnet NICs)
This AQC107 is a popular chip sold under lots of brands (Syba, TRENDnet, Sonnet, TP-Link, etc). If anyone can confirm another brand's version of AQC107 doesn’t have this issue that would be awesome.
