Installing jetpack without the Internet

I am using TX2 board. I can’t use the internet since 2 days ago. Neither wired nor wireless works.

I think it’s because I’ve changed some settings to use “VNC”, so I’ve gone back all of them.

But it still doesn’t work…

The wlan driver is missing.

currently, the TX2 is equipped with a “jetpack”.

I’m thinking about installing jetpack again, but I wonder if it won’t be a problem even if the Internet doesn’t work.

please help me… Thanks in advance.
