Keeps Dropping WiFi - DirecTV

My WiFi signals keeps getting dropped from my DirecTV. The signal is strong and is always available on my computer and telephone but is rarely available on the actual television. I connected via an ethernet cable and was able to keep the signal for an astonishing one hour!! This is very, very frustrating, to say the least. I have looked online and it appears many people have this very same issue. I have done everything in order to make this work, all to no avail. My password has the number 1 in it and I am beginning to think this may be causing the issue? I would appreciate any help you may have to offer!

Thank you,
