does your router have wireless functionality built in?
if not then you need to either buy a wireless adsl modem router to replace your current one or to buy a wireless access point to attach onto your existing modem
are you on an adsl package currently (ie do you use that modem to connect to the internet?)
if you do not have adsl currently and literally do have dial up where you plug the phoneline into your computer direct then you will need to contact TelOne to sign up for ADSL
if you are talking about wimax, then you just simply go to a company that sells wimax (Zol, utande or YoAfrica to name a few) and sign up for the service - you cant use your current modem with that, but they will sell you the kit you need ($500 approx if you need external gear)
