  ubuntu slows down network

Status in “linux” package in Ubuntu:

Bug description:
  Ubuntu 12.04 LTS (32) installed on a HP G62 (i5 processor) connected with wifi.
  router = netgear WNR3500L
  It's working great, speedtest showing 41/48 Mbps down/up.

  However, other equipment in the house virtually comes to a halt.
  Windows laptop goes under 1 Mbps down/up.
  But also ipad, iphone, android phone, all are freezing.
  As soon as i disconnect the wifi on ubuntu, other equipment goes back to normal speeds.

  Have not included further detail is i have no clue where to start....

  Thanks for any help / suggestions.
