Hello, your system uses a Gigabyte Z390 M GAMING motherboard with two M.2 slots. You aim to install dual-band 5GHz and 2.4GHz Wi-Fi adapters using an Intel Wi-Fi device. On Pcpartpicker or Intel’s site, you see these devices listed as mini PCIe or half mini PCIe, which seems compatible with modern setups. However, when you add your current parts to Pcpartpicker, they disappear except for older PCIe models, indicating a compatibility issue. The problem likely stems from outdated PCIe versions or driver mismatches. Regarding adapters, yes, there are solutions that convert mini PCIe devices into standard PCIe slots—search for “mini PCI to full PCIe adapter” or compatible third-party products. Focus on drivers and firmware updates for Intel Wi-Fi to ensure smooth operation.
