Cannot SSH into Jetson Nano

Hi,

I’ve been trying to connect to the Jetson board through SSH with no luck.

I created a wifi hostspot with the host PC on which the Nano is connected thanks to a USB Wifi adapter.

The very first connection was succesful and since then I cannot make it work anymore (the Nano is still connected).

Here are some things that might be useful :

$ssh -vvv mpariente@192.168.55.1
OpenSSH_7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n  7 Dec 2017

debug1: Connecting to 192.168.55.1 [192.168.55.1] port 22.

$ nmap 192.168.55.1

Starting Nmap 7.60 ( https://nmap.org ) at 2020-01-09 12:05 CET
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 3.03 seconds

And, when I’m on the Nano, ssh localhost work.

Thanks in advance,
Manu

usb wifi adapter should be having some dhcp address issued by the host pc or host pc should be using a different network than 55.1, in case you are using wifi connection and not usb-to-usb

What is the output of

ifconfig

if you execute it at nano device?

Sorry, I was using the l4tbr0 IP address instead of the wlan0, my bad.

Thanks for your help.
