  • Which kernel are you using (please provide uname -a)? 3.17.x mainline kernel showed great improvement after I tried different devices (Intel, Realtek, ASIX) in the same situation (sitting just next to the hot spot and having very low connection quality). – Kalle Richter Dec 14 '14 at 14:00
  • Linux aditya-HP-Pavilion-15-Notebook-PC 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux – Aditya Lunawat Dec 14 '14 at 20:06
  • This is the output of the command – Aditya Lunawat Dec 14 '14 at 20:07
  • If you can, edit the question and delete your comments to make it readable. Do you have the possiblity to test a mainline kernel (following instructions at http://askubuntu.com/questions/119080/how-to-update-kernel-to-the-latest-mainline-version-without-any-distro-upgrade)? – Kalle Richter Dec 14 '14 at 20:30

Maybe your wifi is set to power saving?

power.d > set the wifi to no power savings.

iwconfig wlan0 power off
