Hi all,
I’ve been fighting with trying to create a 5ghz AP/STA and I came across an interesting discovery. I’m wondering if any of you have experienced this. The card in the Nano shows that 4 channels in the 5ghz range can radiate, but the Xavier does not.
One thing I noticed in the iw reg list output below, is that iw recognizes the region as US on the Nano, but not on the Xavier. Does anyone know if this has something to do with the deployment of the OS against the particular platforms? I’ve attempted to set the regions on the Xavier, but they don’t change. This may have something to do with the wifi card permissions.
My two setups are:
- Jetson Nano w/ dev board.
- Jetson Xavier AGX w/ dev board.
Both units have a intel 8265NGW mini-pciE card installed with antennas attached.
iw list output for both cards (I’m only clipping the important bits):
