For the layman, the suggested fix in comment #18 means:
- Go to https://launchpad.net/ubuntu/saucy/+package/bcmwl-kernel-source
- Click the link under Source package
- Under Builds click either saucy i386 (for 32-bit) or saucy AMD64 (for
64-bit)
- On the next page, under Built files, click the
Great. So to other users affected by this bug, simply apply the
broadcom-kernel-source package from saucy as described in post #18
above.

Broadcom 4313 causes heavy interference with wireless clients
I've been trying the drivers from saucy (i.e.
6.30.223.30-bdcom0-ubuntu1) for the last week or so. The interference
issue is either entirely gone or significantly reduced. If this is true
for other users, we should probably suggest upgrading as a workaround

Could you open a root terminal and run iwconfig? What you get? Did you
get a kernel panic?

To make my comment above a little more specific, the version of bcmwl-
kernel-source that does not cause interference in my tests is
5.100.82.112+bdcom-0ubuntu3 (the last release for quantal).

I confirm that the current version of the driver bcmwl-kernel-source_6.20.155.1
on my dell E6520 laptop creates severe interferences with other wifi devices.
I just did the same test as above, after installing the same older version of
the driver bcmwl-kernel-source_5.100.82.112, and it works
I just compared the current version (6.20.155.1) of bcmwl-kernel-source
against the 5.100.82.112 version of the driver from quantal (downloaded
from http://packages.ubuntu.com/raring/amd64/bcmwl-kernel-
source/download)
Experimental setup was as follows:
Computer A: BCM4313 on Windows pinging
disabling the proprietary driver does not resolve the issue on my Dell
E6430

Title:
Broadcom 4313 causes heavy interference with wireless
Uninstalling the Broadcom 'wl' driver worked for me (on a Dell Vostro
3500 with BCM4313 PCI wireless adapter). The open-source brcmsmac
driver that gets loaded instead of it doesn't have this problem.
To switch from 'wl' to 'brcmsmac' (on Ubuntu 13.04 anyway), simply:
sudo apt-get remove
I have previously disabled this driver in softtware sources -additional
drivers;
Package 'bcmwl-kernel-source' is not installed, so not removed
Yet the issue remains, I do not think this is solely a driver issue.
What else can I do to debug?

I can also confirm this behaviour on my Dell latitude E6430

When the adapter is turned on, other wifi devices experience wifi
interference and signal
Finally I could take a picture of the error I meant. It usually occurs
after unsuccessfully trying to suspend. Also occurs spontaneously. Like
Weeks, smartphones and laptops cannot properly access to the Internet.

I also have kernel panics (really doesn't, but very similar). Possibly
caused by wireless process ioctl fault. Sorry I haven't any picture or
more specific information but definitly is the wireless LAN.
