Why won't my ematic egq780 tablet wifi stay signed in?

When I had slow download speeds, my tablet, iPad ,printer, and computer would disconnect . This would happen when I was using 2 or more devices and had slow download speeds. If you have DSL service it common for the speed to be slow. To check your speed go to the Internet and type in speed test. I have a free app called ookla. It is easy to use. If you have slow speeds(1.5 mpbs or less) you can check telephone and cable connections to make sure they are tight. Sometimes the routers slow down when they get old. I finally solved the problem by having high speed service installed. It isn't much more expensive and 7 devices can be used at the same time. I hope this helps you. Good luck!
