Fedora 17 -> Fedora 19 Failing Broadcom 4311 problem

I'm trying to keep my aging laptop (HP dv6226us) limping along with a failing Broadcom wireless card (white-listed in the bootrom unfortunately).

02:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

In F17 after the wireless card dropped and then refused reconnection, I could stop NetworkManager, modprobe -r (remove) the b43 kernel module (a few others were unloaded as a result), then modprobe (load) the b43 mod back in and start the NetworkManager ... and it worked (at least for a while). With F19, this procedure no longer works at all and a reboot is the only solution I have so far.

What changed between F17 and F19 so that my "recovery" procedure stopped working?

Suggestions for other workarounds? ... setpci commands?

[I'm getting closer to buying a pico USB WiFi plugin just to have another connection. Any recommendations on which work better with Linux?]

UPDATE

It's been quite a while since my Broadcom card has crapped out. Starting to wonder if some combination of b43, NetworkManager, wpa_supplicant, and d-bus, etc., was causing the problems all along. Will need to wait for failures to begin testing again.

UPDATE UPDATE

After recent WiFi stoppage, tried my answer below and it worked!

Fresh installed 19 or upgraded from 17?

From F17: $ fedup-cli --network 19

Try fresh install.

Will try "fresh install" as _the_ last resort. Why suffer hours of downtime with no certain solution at the end? May as well have BSOD.

Ridiculous Karma requirements prevent me from commenting on the answer below suggesting the Broadcom STA driver. Unfortunately it didn't work (kernel boot messages screamed like a Banshee) and blacklisted the b43 module, etc. Some painful kernel debugging got me back to where I was (and am now). Trying to modprobe the wl driver into the kernel resulted in a segfault. Is the wl module compatible with F19?

Don't know the root cause, but when the WiFi fails, this works to get it going again:

$ service NetworkManager stop
$ modprobe -vr b43
$ service wpa_supplicant stop
$ service wpa_supplicant start
$ modprobe -v b43
$ service NetworkManager start
