Title:
  Realtek rtl8187b wireless chipset slow speed

Status in The Linux Kernel:
  Invalid
Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  Hi, I have ubuntu 11.04, all updates, wifi chipset rtl8187B, kernel 2.6.38-10, and 14mbit/s internet connection. 
  When I try to download something, for example from torrents, I see ping up (up to 500-800ms), slow speed (<1mbit/s) and packets lost.
  In windows its works fine, ping didnt up, download speed 14mbit/s. 
  So if I want to download something, I need to reboot from ubuntu to windows, or wait for download at low speed in ubuntu. And it's not good=(
  Thanks, and sorry my bad english.
