Broadcom Wireless adapters and kernel updates

[Temlakos]

Everyone:

Updating to the new kernel temporarily knocked out my wireless 
connectivity on my Dell Inspiron 1545.

That is, until I executed:

# modprobe b43

Or, since I am a member of "wheel":

$ sudo modprobe b43

A few seconds after I issued that command, wireless was enabled, and the 
connection I had long been using, re-activated itself.

Question: must I execute "modprobe xxx" with every kernel upgrade?

(By the way: it turns out that module "wl" is not necessary.)

I'll assume it's solved. I had to "become root" to do it, but I executed:

# echo b43 >> modules

while is directory /etc

Now I have a file called "modules" with the line "b43" in it.

I was hoping that you understood what is written in
"Dell Wireless 1397 WLAN Mini-Card for Dell Inspiron 1545: How to Drive It!" thread,
including links provided.

"wl" is the original *proprietary* Broadcom's wireless module.
"b43" is *intree* Broadcom B43 wireless module.
If both are installed and unblacklisted, they are competing for the same device.
So if everything works OK with "b43", then you can safely remove "wl":

# yum erase broadcom-wl

So there is no need to tamper with the blacklist commands in the configuration files[1].
Besides, with this auto-loading a kernel module shouldn't be a problem.
