Now, there are several options you might choose instead, composer being a top of them. But for this article, I will write down how to update modules using SSH.
For Windows, we are going to use Putty:
From your Drupal installation go to the modules folder
cd /sites/all/modules
now, using wget download desired modules and extract:
sudo wget https://ftp.drupal.org/files/projects/file_entity-7.x-2.21.tar.gz sudo tar -xvzf file_entity-7.x-2.21.tar.gz
Go back to the Drupal website and run updates. Next, you would like to delete tar.gz file from the modules folder
sudo rm file_entity-7.x-2.21.tar.gz
