Using Realtek wifi module from NX on a Nano

I removed the wifi module a Jetson NX and connected it to a Nano. The module is recognised, but stays off.

$ sudo lspci -v

I’ve been through and compared the NX and Nano package lists and the modprobe lists and don’t see anything that looks like a driver difference between them.

I’m guessing that there’s some configuration setting that needs to be flipped to enable the module to work on the Nano, but I can’t work out what that might be.

have you had any luck? I just did the same (NX module on Nano) and I can’t believe this isn’t working out of the box.

Please try to enable SMMU in your device tree to support 32bit DMA and try again.

I gave up in the end I just gave up and used a Pi for my use case instead. I may revisit this later on, but probably not until they update the kernels and maybe things will be different then.

Thanks man. If it’s useful to you, I solved it with a 10 bucks USB wifi dongle. It worked out of the box.
