Hi, I have a problem with my connection speed

I formally used a dial up connection to download using Limewire and had the connection speed run at 1-3 KB/s.

I have recently connected to a wireless 'ADSL' which is a much faster connection, yet my Limewire still has its connection speed running at 1-3 KB/s?

Is there a setting I can click to update my connection speed or something, please help!?

Cheers.
