- Download the one you want to upgrade to. Go to the upgrade menu from the one you already installed. Browse to where you downloaded the one you want to upgrade to and select it. Also make sure you check “erase NVram” and then click upgrade. When it is done, your “user name” and “password” will be “admin”. Then configure by hand/manually to what you want. Hope that helps.
