Youre giving not much information of what you exactly are trying to do.
Do you need to use streetmap data or is local stored data also possible?

Basically a route-solve is handled here:

You do no neet internet. You also could use local street data from whereever you get this, and transform this to a traversable network dataset. With this and the network analyst extension you can solve a route (see linked thread).

hey

maybe i think i know the problem.
ArcMao offers two ways to solve a route.
#1:
using the pre-defind rout program which uses maps of the internet (bing maps, google maps, esri maps, something like this).
For this u need internet, yes. This is because it takes map material from some internet based services, like google maps.

#2:
using the network analyst extension:

you are using ArcMap. In the menu of ArcMap you have activated the Network Analyst Extension (checkbox).
When rightclicking on an empty space of the toolbar of ArcMap all available Toolbars appear. Also the network analyst toolbar appears there and it is checked.
The network analyst toolbar appears as tool bar in ArcMap where all other toolbars and the normal ArcMap menu are placed.

For this u do net need internet when using local map material.
You need to have a network (e.g. a streetmap).
For this openstreetmap data is possible (e.g. http://download.geofabrik.de/osm/).
You need to convert this network (streetmap) to a network dataset. This is a kind of an analytical network. The network analyst is able to traverse on it.
To convert openstreetmap files to such an useful network dataset you can use the tool OSM2NDS (by eva peters, esri germany)(http://52north.org/communities/geoprocessing/osm2nds/index.html).

for further information on network analyst extension look here:
http://help.arcgis.com/de/arcgisdesktop/10.0/help/index.html#//004700000001000000

using the network analyst extension takes some time to understand but in this area are some tutorials and videos too i think. Just have a look at my link and also start a google search on this topic.
