2022-03 I bought AC9560NGW at $27 that can reaches 866Mhz with ASUS AC Router. Sellers said 9260 at $70 with better compatibility with same functions. Someone sells AX210 with pcie x1 adaptor at $129.
2022-03 I bought AC8260 at $28 with M2 to PCIe x1 at $20.
2022-04
AC8260 on MSI B450M Mortar Max needs to set BIOS PCIe X1 from PCIE_2 to PCIE_3. Ubuntu 20.04 works well with 866MHz. Test Speed with iCable 130MB/s.
