how to run rocksmith offline without internet ?

 

i'd like to play wherever i am with my notebook.

 

and sometimes their is no wi-fi at all.

 

is there any way not to connect steam and just access on the game (both of dlc and original songs)?

 

please let me know.

Steam has an offline mode and RS can be played even if the game can't log to Uplay server.

 

You'll still have access to all on disc song and DLC that you bought and also all the CDLC that you've downloaded.

 

So you definitly can.
