Xbox Destiny game causing Internet to drop

Hi there,

i I have read all other related posts to this but nothing seems to relate. We have adsl 2 and haven't had any issues with the internet until the new destiny game update which causes the Internet to either connect very very slowly or drop out within 0 mins. Usually during game play! Very frustrating. 

Have tried with wifi and Ethernet but neither help. Tried the usual resetting etc but nothing works.

Any suggestions?

thanks
