I added a 2nd nvme m.2 drive in the Asus strix x470-f with Ryzen 7 3700x. My wifi card doesn't show wifi networks if I install the 2nd m.2 drive. My wifi card has both wireless and Bluetooth but only Bluetooth works once I install the 2nd m.2. If I remove the 2nd m.2 then the wifi works.

Sounds familiar. Wonder if its a feature of Asus bios.

is wifi onboard or an add on card?

Some motherboards split off the lanes going to the m.2 slot from the PCIe lanes, so when you connect a M.2 drive one (or more) of the PCIe slots will stop working. Just try another slot for the wifi card, you probably found the "shared" one.

does that boot thing happen if you remove 2nd m.2 or pci card?

m.2 just meant to disable sata ports, I don't see any mention of PCI lanes

I can find evidence that adding 2nd m.2 does downgrade other pcie slots but it only mentions the GPU slots, since that was topic of question. expect the other slots are shut off at same time.

When I was selected mother boards I saw that due to sharing pcie lanes the in every motherboards for b450 x470 b550 or x570 m.2_2 second slot socket interface if I use the it disables pcie slots or sata ports or downgrade pcie slots.

[SOLVED] - M.2_2 slot if used downgrade pciex16 to x8 mode in Asus Rog strix b450-F

I m planning to purchase Ryzen 7 2700x and was selected motherboard and came across many minute differentiations In slots configurations which made complicated to select a motherboard. As I am planning to build a pc for content creation. Video editing rendering and decided for Ryzen 7 2700x...

which pci slot is the card in?
there are
PCIEX1_1 that is under 1st GPU slot
PCIEX1_2 that lines up with the 2nd M.2 slot (so I assume not this one)
PCIEX1_3 that is at very bottom of motherboard under 1_2
page 1-1

** PCIe x16_2, PCIe x1_1, and PCIe x1_2 slots will be unavailable when installing M.2 PCIe SSD in M.2_2 socket.

link << your motherboard.
note also shows on page vii of your manual above.

Seems only PCIE1 slot that works if you have M.2 in slot 2 is the bottom one.

https://ibb.co/YtGTjjn here is my card .

if you put the card in the slot below it, 1_3, it should work.

the M.2_2 slot, when in use, takes the lanes that would otherwise be used by PCIe x16_2, PCIe x1_1, and PCIe x1_2 slots. You can't use both at once.
