For me none of the other drivers are working, so I'm stuck with
brcmsmac. Have been using it for hours now and suddenly I started
getting very slow DL speeds (~70KB/s). On Ubuntu 14.04 LTS and
3.13.0-24-generic kernel. So, confirming the issue still persists for
newer kernels.

I have this problem, or at least something very similar. I get low
signal strength and speeds with brcmsmac. I also have a broadcom 4313.
The wl driver works perfectly.

Interestingly, even the proprietary "wl" driver seems to have this

With this driver, what is sure and deterministic, is the fact that
activating power management decreases the throughput to ~150KB/s. But

Until drivers in the kernel are fixed, you can use this workaround to
get fast wireless speeds on secured and/or unsecured wifi.
1. Add the following two lines at the end of your
/etc/modprobe.d/blacklist.conf file
blacklist bcma
blacklist brcmsmac
2. Install proprietary Broadcom STA wireless
Still very slow download speed on unsecured wireless connection in
3.0.0-14-generic kernel.
UNSECURED Wireless speeds:
Download ~ 0.40 Mbps
Upload ~ 3.5 Mbps (this one is good)
On secured wireless (WPA/WPA2) both download and upload speeds are fine.

Posted #7 little too fast. The good news is only partial.
On SECURED (WPA/WPA2) wireless the 3.0.0-13 kernel works great but on
UNSECURED connection wireless is still very slow (56k or so).
Could someone confirm this behavior? Also, could someone check WEP
secure connection too?
