I'm trying to install wpasupplicant 2.1 because I'm having some problems with 2.4 . I tried:
sudo apt-get install wpasupplicant=2.1-0ubuntu7
wpasupplicant version cannot be found. I found the archives and downloaded manually
wpa_supplicant-2.1.tar.gz. How would I go about installing it though? I couldn't find any comprehensible instructions online and am newbie.
