I have followed your suggestion and all seemed fine. 

After rebooting I tried to do the modprobe but got the following:

[root at gary ~]# modprobe wl
modprobe: ERROR: could not insert 'wl': Required key not available
[root at gary ~]# 

This relates to the secure boot that is mentioned on the page. I therefore 
went through the process of disabling secure boot.  This consisted of 
running:

[root at gary ~]# mokutil --disable-validation
password length: 8~16
input password: 
input password again: 
[root at gary ~]# 

After doing this I rebooted. As part of the reboot I was supposed to be asked 
for the password that I had just created but I wasn't. Then, after the reboot 
I tried the modprobe command but received the same error message.

Anyone got  ideas what I need to do next?
