    Wifi modem / router is an AT&T model 4111N. I have 5 computers linked, 5 phones linked, and 2 tablets. I'm trying to link the ellipsis 8. Yes password is correct, and I can link to other secured and unsecured wifi systems. I have rebooted the tablet to connect as well as the wifi router. I have viewed the tablet trying to connect, but I keep getting an "authentication problem" error message, then the tablet keeps trying to connect over and over. I'm trying to troubleshoot as to where the "problem" lies. Welcome solution. Thank you, David

    Make sure your DHCP range is wide enough to accommodate all of your devices. Also try turning off your network's security temporarily.
