[Bug 1325145] Re: Intel Advanced Centrino N 6235, Slow WIFI since 14.04

 

Note, that this is tested on the 2.4GHZ network with an Asus n66u wifi
router.

Using the 5ghz network on the 3.11 kernel I'm able to reach speed above
200mbit/sec.

Tests are done 1 meter away from router.

Title:
  Intel Advanced Centrino N 6235, Slow WIFI since 14.04

Status in “unity” package in Ubuntu:
  New

Bug description:
  Using Kubuntu 14.04 LTS here, upgraded from 13.10.

  Whenever I use the standard Kernel linux-image-3.13.0-27-generic thats
  from 14.04 I cannot get my WIFI to go faster than ~25mbit/sec download
  and about 10mbit/sec upload.

  However, once I boot back to linux-image-3.11.0-19-generic, my speeds
  go back to about 90-100mbit/sec download and 100mbit/sec upload too.

  This problem also exists within the kernel ppa .deb kernel: linux-
  image-3.14.4-031404-generic
