Title:
Intel Advanced Centrino N 6235, Slow WIFI since 14.04
Status in “linux” package in Ubuntu:
Confirmed
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
