I have a Jetson Xaiver NX and a Windows Laptop, both connected to home WIFT and I use putty/WinSCP from Windows to login to NX.
I recently changed my home WIFI names (SSID). After this, I restarted my NX, connected to the name WIFI names with new passwd and could go online without any problem. I used “ifconfig -a” to find the new ip address of Xavier NX.
On my Window machine, I also connected to new WIFI SSID and go online without any problem. However, I could not ssh from my WIndows to NX with putty or WinSCP.
