TNAS how to install wget

I don't have a Terramaster TNAS but I do have quite a number of QNAPs. On these the usual approach is to install Entware from https://github.com/Entware/Entware/wiki.

Entware takes over /opt and uses its opkg package manager, so

export PATH="/opt/bin:$PATH"
opkg update
opkg install wget

Thereafter,

wget ...

If no apt and no yum, you have to get it from somewhere else. Luckily this an intel based system (file /sbin/init or uname -a) you can download a already compiled wget binary from somewhere else and copy it onto the system. You got to take into account libraries already installed. Maybe curl is installed?
