Broadcom wifi cards are notorious for being problematic with Linux, so much so, that one of our LQ members, frankbell, has posted this "sticky" on the subject:

Please read and inwardly digest.

Hello and welcome to the forum

Just to make sure, please open a terminal and post the results of these commands...

Code:

lspci -nnk | grep -i net -A2

Code:

iwconfig

Please omit nothing from the results.

Which kernel version?

Code:

uname -r

Maybe the RHEL6 kernel is too old to support the 14e4:4365 chipset? This chipset is supported by the brcmfmac driver and firmware is required too.

The proprietary Broadcom driver may be an option for you, but I'm not familiar with using RHEL to advise in further detail

Hi all...

According to this page and others I've seen, the chip in question is the BCM43142 and it requires the "wl" driver. I'm not sure if the brcmfmac driver is the same thing or provides the same module. If the correct driver can be found, I did find some installation instructions here, although some, if not all, of the links or dead.

The page supplied by ferrari above should resolve this problem.

@ferrari: Good find!

Regards...

That's for the ethernet adapter, the OP is asking about the wireless.
