When we first got the wifi router modem we also got an echo dot. At first the dot worked fine on it. and stayed connected. Then someone had trouble connecting the wireless printer and changed some stuff inside the settings. After that nothing would connect so we called and tech support went into the router and changed some settings so that our laptop and cell phones would connect again. The trouble is that the dot won't stay connected for more than a half hour ever since. What do I need to do in the settings to get the echo dot back on and so it stays on. Also, the printer is still touch and go to. Would a factory reset fix this? Should we turn off the Exede modem's wifi and hardwire our old Linkseys into it instead? Some help would be appreciated. Thank you!
