Problem:
Seattle resident on Alki Ave SW was having problems getting Netgear R6220 router to work with Comcast. This in turn prevented computers, smart phones, and Roku from connecting to Internet.
Solution:
Connected to the Netgear R6220 router, installed updated firmware, and reconfigured wireless configurations with new SSID and passwords. Then got all devices connected to Internet. As a benefit to the customer, added free channels into the Roku that provide access to International news streams not available on Comcast TV.
