it appears those are closed source drivers with funky licenses, so they can't just be redistributed without assumption of liability.
Correct, elrepo isn't able to freely redistribute the drivers due Broadcom's licensing, but does provide instructions and a SRPM (minus tarball) for you to build yourself.
Every time I encounter big enough trouble about some chipset to have to learn a bit about its internals, I usually learn about its engineering flaw. BCM43xx has the following one: the chip internally is 32 bit, though it sits on 64 bit bus. (Take that with a grain of salt, it's been long time since I looked into that crap).
Once I discover the flaw, I add particular hardware in my black list and do my best to not buy anything containing it. Broadcom as a whole is not in my black list, they have great hardware, but their BCM43XX is, even if they corrected their design flaws since.
I would replace that if possible (Intel would be great candidate), or use USB adapters others suggest.

That's what I have to do, and it can sometimes be a PITA because a kernel update can break it and you have to build it again.
With major updates (like 7.3 to 7.4) you sometimes have to download a new nosrc rpm.
Alternatively, for $8 you can purchase an adaptor that is natively supported and will work out of the box:

https://www.newegg.com/Product/Product.aspx?Item=N82E16833315091&cm_re=e...
The above adaptor is based on the Realtek RTL8188CUS chipset and uses the rtl8192cu kernel driver.
At some point I will be replacing mine, but with a low-profile PCI-E card. I've had bad luck with USB wifi adapters, sometimes for example they lose connection when a microwave is turned on and when I was visiting my parents, had one that lost connection whenever the AC unit kicked on.
My best wifi experience in Linux has been with my T series thinkpad, it uses some kind of Intel wireless chipset that is in the kernel.
I'm going to be looking for a low profile Intel PCI-E card, but for now my broadcom PCI-E actually works quite well - with the exception of needing to rebuild every now and then (last time was 7.3 to 7.4 update)

Hey ... Thanks for your help everyone.
Looks like I will need to try my hand at the compiling process or purchase an intel based chip board.

yeah, Intel wifi cards are generally excellent and well supported.
I don't like USB wifi at all. the antennas are tiny and have very poor gain or efficiency. you want to get an internal mPCI-E card or whatever it is your laptop expects, as that will connect to the built in antenna which runs along the top of the screen on most laptops and will give you FAR better signal gain resulting in better range, and faster transfers
