What I can see, the WiFi runs stable, if nobody connects to it. The failure starts, when somebody connects and does some throughput. > Looks like the device went into a very confused state due to pcie link > failure starting from: Well, I did a test and removed the Mikrotik RB14e, as it has a PLX chip and provides an extra pcie switch. Instead, I took a simple passive miniPCIe->PCIe adapter and build only one card into it. The problem still exists. So, the RB14e is not the cause at least. > [ 691.609836] pcieport 0000:00:02.0: AER: Multiple Uncorrected > (Non-Fatal) error received: id=0800 I see, so the firmware crash it not the cause, but the error reported by AER.

Perhaps there's a pcie bridge > problem on your host platform or maybe an electrical issue (e.g. > insufficient power supply to handle short bursts?). Well, the mainboard is microATX. So its powered by a Seasonic 400W passive PSU, but the whole system takes about 40-50w. So the PSU itself should be enough? ;-) IIRC PCIe should provide up to 75W? I am out of ideas.. I know, a year ago, that cards were perfectly working. Even a test replacement shows the same errors, so it's not a defective card.
