Xavier can't maintain Network connection

Hi, I have a serious problem in my Jetson Xavier network connection.

I’m using ipTIME N100 mini WiFi adapter in Xavier and when I turn on my Xavier, it could find WiFi and connect well.

A few minutes later, however, the connection is down.

So I checked the networking information by ‘ifconfig’ but IP is still alive.

I try to connect with LAN but it dose not worked.

I have no idea how to fix.

Please let me know the reason and how to recover.

Thanks.

Could you share the dmesg log?

In the same time pls try sudo iw wlan0 set power_save off .

Sorry to reply late, last week was holiday in my country.

I’m not sure which information you exactly want, so I copy all thing about ‘dmesg’.
