You need the launcher to run minecraft, minecraft.jar is useless without it. The best solution would be connecting it to an ethernet cable or purchasing a wireless adapter off of amazon or ebay. I personally have the asus usb n-10 for my dinosaur of a computer.

You can't. You must be connected to the internet to do so.

Move the computer temporarily to a location where you can connect to the router by ethernet.
