Wi-Fi Freeze?

[mpath]

on mac 10.9.2 ,using bittorrent 7.4.1

 

after starting a torrent it goes at a good speed for a bit then stops. almost always if I'm using my browser safari 7.0.3 but when it stops all my wi-fi is frozen for the whole house till i turn off my macs wi-fi and back on then it starts back up with no problems sometimes it will go a whole torrent but most times its like once a min i got to turn it off and back on. do to the internet freezing also other people in the house are getting mad i tried changing ports still no fix. i also download late files other ways and have no problems. only when i use bitTorrent. and i tried limiting bandwidth still no luck.
