Hello. I am running a total of 7 3MP Amcrest IP cameras, one of which is hardwired into my Comcast modem. I am having trouble with loss of signal almost 200 times a day if not more, even from my hardwired one (I dont know why). However I do have many WeMo light switches, 2 Google Homes, 2 Computers, etc all running on the same SSID and Modem. I am running Xfinity Extreme (fastest internet they offer). I know I can buy a switch and hardwire all of them. My question is, can I install a separate router (LinkSys) to my Comcast (modem & router) and link my Computers, WeMo's, Google Homes, etc and just leave the 7 IP Cameras linked to the Comcast modem/router? All help is greatly appreciated!!
