Dear developer team, I have to admit, the earlier post "HTT timeout error with NCM86" is my fault, sorry for causing confusion. Due to earlier tests with legacy cards, the PCIe slot was still forced to Gen2 :-( Putting it back to <auto>, with "MSI HERALD-BE", similar to "Gigabyte WC-WIFI7" i consistently get: "Unknown hardware version found for WCN7850: 0xf" Which nails down to the question whether any of these adapter is already supported? The M.2 NCM865 card as such seems to be supported. I'm wondering about the difference, as there seems to be no additional logic compiled on one of the two PCIe boards, just bit of glue logic. Thanks a lot for any hint, Dieter
