A:AnswerDid you connect the PRINTER to your WIFI? It doesn't matter if your computer is connected to the printer. It's weird, especially since Epson didn't bother to include a part, i.e., USB connection that probably costs less than $50, yet the printer panel shows that as an option. You have to connect your WIFI FROM the printer panel.
A:AnswerI recently just purchased this printer and have had no Wi-Fi connection problems. The color black seems to be fine. You might have a bad batch of the black. Maybe wait till after you refill it.
A:AnswerThe problem with T Mobile internet is that they do NOT have static IP addresses. Their IP addresses changes frequently throughout the day. Their IP address is what's called "dynamic." Both of which, to me, should be just the opposite. "The opposite of a static IP address is a dynamic IP address. Unlike a static IP, which remains fixed and doesn’t change, a dynamic IP address is assigned dynamically by a network’s DHCP (Dynamic Host Configuration Protocol) server. Dynamic IPs are often used for devices that connect to the internet temporarily or frequently change networks, such as smartphones, laptops, and home routers."
