On the flipside, you can actually make your own portable wireless router with less than $40.
You can do this by ordering your parts online. If you search eBay then you will find that you can get a wireless router for as low as $15.

That means you won’t have to open the hood or the trunk and try to wire in a new car battery. You can simply go to Wal-Mart or RadioShack to get a car battery charger that fits into the socket for the cigarette lighter.
