[Bug 1426852] Re: broadcom drivers on ubuntu 14.04
** Description changed:
This annoying bug is found on broadcom drivers for 14e4:4365
- i even downloaded and compiled latest broadcom drivers at
+ i even downloaded and compiled latest broadcom drivers at
http://www.broadcom.com/support/802.11/linux_sta.php
and i applied a patch from here
https://aur.archlinux.org/packages/broadcom-wl/
- It the same,
+
+ Its on Ubuntu 3.13.0-32.57-generic 3.13.11.4
+
+ What happens is that wireless signal is lost every few minutes,
+ sometimes on every half hour or so. I guess it depends on strength of
+ the AP signal.
+
+ Also, every signal to AP is show as "weak" no matter how close i am to
+ the AP it self.
+
+ This is from dmesg

Title:
broadcom drivers for 14e4:4365
Status in broadcom-sta package in Ubuntu:
New
Bug description:
This annoying bug is found on broadcom drivers for 14e4:4365
i even downloaded and compiled latest broadcom drivers at
http://www.broadcom.com/support/802.11/linux_sta.php
and i applied a patch from here
https://aur.archlinux.org/packages/broadcom-wl/
Its on Ubuntu 3.13.0-32.57-generic 3.13.11.4
What happens is that wireless signal is lost every few minutes,
sometimes on every half hour or so. I guess it depends on strength of
the AP signal.
Also, every signal to AP is show as "weak" no matter how close i am to
the AP it self.
This is from dmesg
