If I restart my computer with the following in /etc/modprobe.d/blacklist.conf:

blacklist b43
blacklist ssb
blacklist wl

Then I can either modprobe wl (broadcom STA, works well) or modprobe b43 (highly unstable on my B4331 rev02).

But if any any point I load the b43 module, nothing I can (figure out how to) do will allow me to load wl without restarting my machine.

For example, if I:

modprobe b43 # --> working network access
rmmod b43 brcmsmac ssb bcma wl
modprobe wl
iwlist scan

This yields 

eth1      No scan results

I'm trying to figure out what state is being changed, such that modproble b43 && rmmod b43 is having some detrimental net effect. Any thoughts on how I might be able to "recover" from loading b43 without rebooting?

Thanks!

Have you tried to make and run a script like this:

 #/bin/sh

   Case (wl) in
      networkname = (ip adrs of wl)
      gksu networkname
      nmcli -Cl networkname
      resolv (the ip adr of wl) >>
   endl
   Case (b43) in
      networkname = (ip adrs of b43)
      gksu networkname
      nmcli -Cl networkname
      resolv (the ip adrs of b43)
   endl

and it might work fine this way,

If you have not done so already you should verify if you actually are unloading all the modules that need unloading when you have loaded the b43 module.

To verify that boot your system and then execute this:

lsmod > before_loading_b43.txt

Then load the b43 module like you would normally.

Then run this:

lsmod > after_loading_b43.txt

Then compare those files to see which modules are added after you load the b43 module.

You could use diff tool for comparison like:

diff before_loading_b43.txt after_loading_b43.txt

Or a graphical file comparison tool could be used.
