How does wireless internet work in South Korea?

I have a macbook pro and am going to be a student in yonsei university. If I have my own apartment how do i get wireless internet service? Do I have to go personally to the company? Is it already set up standard? What are the monthly prices usually?How does wireless internet work in South Korea?
at first, in Seoul, free-wireless internet is able to use.



but you should endure, some slow speed.





and second, near university, there's another wireless service. that's free, too. and moderate speed.



most of students are using university wireless internet.





at last, though you can set LAN connection up at apt, using wireless is possible -- not that speedy.



So far is free-wireless.



so, you can pay about 20,000 won (about 18 bucks i thought) to use wireless internet.



it is the best choices to above all.



so, good luck~
