Speedefy High Speed Pro WiFi Router (Open Box)

It didn't come with clear and adequate setup instructions, and the alternate instructions I found on the web didn't make it work either. And the original included instructions, combined with the Speedefy Setup page, defaulted to Static IP address, and said to get some number or code from my current WiFi router, but I could find that number or code when logging into my current WiFi router, and there were no alternate instructions for what to do if that number couldn't be found. The web instructions, which said to select Dynamic ID Address, said there would be a Save button, but there was only a Next button. So I can't tell if it didn't work because the instructions didn't match, or for some other reason. And the Speedefy setup web page was pretty confusing, compared to setup pages from more major router manufacturer. For example, once I selected Dynamic IP Address, it showed Next and Skip buttons, but the Next button didn't do anything, so I had to use Skip. So I don't know if the problem was with the Speedefy setup page. All of Speedefy's instructions assume that you know what every acronym is and how to find information about that. They're not set up for someone who doesn't know all those acronyms, such as someone who's been using the same WiFi router for many years. My WiFi router still works fine, it just can't support a printer for some reason, and I was just trying to get a new router with printer support. This was my first experience with an "off brand" WiFi router, and I'll take care to avoid "off brand" WiFi routers in the future.
