If Gateway modem (from Comcast) is not being "seen" by a laptop, will Comcast tech be able to help?
Switched out the older Cisco modem and changed to the Xfinity Gateway modem recommended by Comcast. Encountered several issues in re-configuring my devices to the new modem. Established connections to all except an Asus laptop. Could I trust a Comcast tech to resolve the issue?
