how to test wifi in tx2


i want test wifi in tx2 board.

meains wifi is available or on in tx2.

any command or method to check this

I’m not much of a WiFi person, but the wired command “ifconfig” (which does show some wireless info) has the wireless version “iwconfig”. Basically this can tell you if a wireless interface is up or not.

Or are you asking how to look at the outside world and see what WiFi is out there? If so, then you want “iwlist”. Example:

iwlist wlan0 scan

Both of those are from the “wireless-tools” package.

Incidentally, if you want to take a look at where the short names of network devices comes from:

sudo ls -l /sys/class/net/*

…the part of the path with a hex number and dot and name is the base address (useful in device tree edits) and the name of the controller or driver.

See also:

1.]iwlist wlan0 scan

nvidia@tegra-ubuntu:~$ iwlist wlan0 scan
wlan0 Interface doesn’t support scanning.

after this command it show like this…

any solution.

Just to emphasize, I am not really a “wireless” person. However, this sounds like the firmware is missing. Is this a development kit board? What L4T release version has been flashed (“head -n 1 /etc/nv_tegra_release”)? Has there been any kind of additional update other than flash?
