No other changes to my system were needed (or desired); the new Avast version fixed my problem, as I suspected it would.
It's still a good idea to upgrade your driver. 
No thanks -- "if it ain't broke, don't fix it!" 
Why aren't you still using DOS 
Is this a serious question??? Do you really think an unnecessary driver update is the same as moving to a new operating system? If so, I'm beginning to understand why we aren't communicating -- we see the world in vastly different ways.
Here is a challenge for you: Do you know exactly what got "fixed" in the "updated" driver version you are referring to? In other words, do you really know why you updated? Well, I did a little homework and the 5.x versions of this driver just added support for countries that I don't live in. There is absolutely no reason why I need to install this driver when the one I have works fine (in the USA).
If you and others want to tweak your systems like this, that's entirely up to you. But I don't care for the "evangelists" continuing to try selling me something I don't want. Can we just let this thread die? I started the thread because I had a bug to report, and now that Alwil has fixed the bug I really don't have anything else to say on this topic.
XP was working fine for me.
I still upgraded to Windows 7.

Thank you.
Let me tell you about an experience I had with a Realtek audio driver.
I did not notice any problems with my audio.
However, I upgraded to the latest Realteck audio driver and guess what.
The sound quality of the audio improved immensely once I upgraded.
Vendors don't normally upgrade their software unless the upgrade is an improvement.
Maybe you upgrade the Broadcom driver and your wireless connection becomes more secure as a result even though it appears to be working fine without the upgrade.
People who stay with outdated software rather than upgrade do so at their own risk.
In my humble opinion, it is better to stay current rather than keep something old even if you think it is working, unless you can't afford the upgrade which is not the case with the Broadcom wireless driver.
