nokia lumia 920 transfers data very slowly

[Christopher 3]

i just purchased a nokia lumia 920 and tried to transfer some pictures and music onto it, and it is just taking forever, or it won't work at all.
transferring 24mb of data took almost 5min (no exaggeration)! and the bigger the files the longer it takes!
can someone point me in the right direction here? i'm getting very frustrated with this issue!
