It was working flawlessly until the update to 175.
But I get it, it might be the PCIe slot. Blowing and cleaning with alcohol didn’t make a difference.
I installed another identical card into a different slot ( The full PCI) and it has similar issues, but after a few restarts the 2nd card works,
I upgraded to 177-testing, it made no difference.
I tried to switch between 1st and 2nd card using setup assigning NIC to Green and the “2nd card in the full slot” always needs a few restarts but then it works. The 1st card doesn’t.
I see someone else is experimenting with the same Rev 15
