While wifi internet is easy to set up, cheap, and reliable, there are times when having a wireless network might not be an option. The first example that comes to mind is inside of a college dorm room. Many college dorms only provide you with an Ethernet cable on either side of the room, one being for yourself and the other being for your roommate. I struggled with this limitation myself during college being as I was one of the only people I knew with multiple computers. Sadly I was unable to find the answer then and suffered through it until my last year when I was able to get an apartment. I thought my days of dealing with such a closed network were over but then I moved to Korea. In Korean dorm room style apartments, the internet is set up in the exact same way as in most colleges. The difference is that it is much easier to stop by your IT department and have a word with someone than it is to even attempt communicating with your Korean landlord. I bought a wireless router and learned the hard way that I was not going to get wireless internet without buying an additional router from my service provider and paying extra. After many long nights and endless frustration, a friend suggested this quick fix.
