Comcast gateway & epson printer loosing connection

Anybody that has a Epson printer & using a Xfinity gateway & found one day the printer stops connecting don't call Epson, this probably happened after a printer firmware update that causes it to loose the ip address.So after you restart the printer it comes back on line but off again after coming out of sleep.To fix this issue just simply separate the bands by using 2 ssid & presto its fixed.
