If you want that for the computer, I would not bother.....

You will find that free wifi is available, almost everywhere. And where you have to pay, it is quite cheap. Most hotels give it free, as do motels, hostels and campgrounds. Many of the interstates have free wifi at rest areas, and places such as McDonalds, Starbucks, Panera and others, even some general stores and supermarkets, offer free wifi. I asked everywhere I went, and was often told it was available free, even though there was no sign saying so.

Have a safe trip.
