Time machine backup

I have a Macbook pro running Mountain Lion. I bought a MBL recently. When connected directly to my laptop I get transfer speeds of about 15Mb/s but over my wireless network its about 0.2Mb/s. Does anyone have  solutuion?

Depending on what is the wireless protocol your router supports (A,B,G,N), it could be a lot slower that using a wired connection. If you are using WD2go to access the My Book, the transfer speed will depend on your internet speed.
