[lubuntu-users] Difficulties with wifi during installation

[JMZ]

Hi,

Recently when I've tried to install Lubuntu, I've found that the wifi 
setup screen will not recognize my passcode.  There is only one account 
on my wifi system.  All the other computers, tablets, phones etc. accept 
the passcode, so the problem is not a bad passcode.  I had thought that 
I could enter the passcode later after Lubuntu had installed and then 
run sudo apt-get upgrade, but I couldn't logon to my wifi after 
installation.

There are two installation programs for Lubuntu: one graphical and one 
text-based.  The graphical installation program is the one giving me 
grief -- the passcode works fine in the text-based version.  Is there 
any way for me to download a newer iso of Lubuntu with the text-based 
installation program (such as 17.04 zesty)?  I had the text-based 
program on an old 16.04 thumb drive, but this drive is now useless.

Thanks, Jordan
