I realize that there is a lot of talk about wireless drivers, as well as a lot of suggested solutions. I believe I have tried a lot of them and am now with a new install open to new suggestions.

Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)

Does not react to any of the drivers explained in this very detailed and otherwise useful question.

It has been suggested that for a 14e4:4727 it shouldn't be necessary to install any drivers as they are "installed by default in the package linux-firmware".

As this did not work I latter tried with drivers suggested by "Additional drivers" with same lack of result. As of course with the rest of the mentioned drivers. I did not use several drivers at the same time.

I should also say thatrfkill listdoes not show anything blocked and the wireless adapter is on.

Any suggestions?

I just went through the setup process for the 14e4:4727 adapter using the second answer of the question you linked to. The brcmsmac driver should be install by default, as you said. What you'll need to do is remove the other drivers like this:

sudo apt-get remove --purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

and reboot, after that it should work!

I also read around about editing /etc/modprobe.d/blacklist.conf to disable the other drivers, but I didn't think this configuration was worth it since I won't be changing my wireless network adapter hardware configuration any time soon.

EDIT: I expanded on this answer to build the right strategy to get this to work.

Acer Aspire with BCM 4313 has run problem free since 2012 with Ubuntu 12.04 and recently 14.04 using Linsys Routers and occasionally a Netgear Extender.

A recent upgrade to Hiltron CGN3 Duel Band Router was a problem for BCM 4313 which although signed on to the SSID would not connect to the internet.

The issue was resolved by a simple change to the CGN3's Basic 2.4G Wireless Settings:

Factory setting on Wireless Mode: 802.11 b/g/n mixed

Wireless Mode RESET to 802.11 b/g

BCM 4313 connection problem was resolved by the above reset.
