my broadband suddenly gone slow. have signed up for wireless broadband from telecom nz. it says 256kbps its become extremely slow like dial up speed. my limit is 3GB per month and on usage u get dial up speed, but i know for sure i have not used my limit. what are are the reasons that broad band gets slow. my lap top is core2duo its not old model. does the fault lie with telecom nz. just not too familiar with the tech terms & how to improve this speed coz it was good at first.
