By default, wget is not installed on the MFEL. Even updating repositories (using EPEL) will not enable wget installation. To overcome this you can use curl as a drop in replacement for wget.
Where you would have used wget like so: wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
You can use: curl -O https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
The -O is important, this tells curl to output to file, by default curl will output to the console (screen) and you will just see a mess.
