We can't check your work and some folk do not want to share the private IP address of 192.168.0.x or such. I can't duplicate in every reply that such information is not a security issue as it's a private address and what that means.
So try the usual DNS of 18.104.22.168 and 22.214.171.124 then hope that helps
TV: Samsung UN55D6000S
Wireless LAN Adapter: Samsung WIS12ABGNX
Internet Provider: Comcast Blast 50mbs
Internet Modem: Comcast/Arris TG862G Gateway
The TV was working fine on the Internet. Now it will not connect. If I try to reconfigure the Samsung network settings the ending message says "network connection complete but unable to connect to the internet". The IP address, Subnet mask, gateway and DNS server in the Samsung network status look OK.
The gateway works fine with 2 wired desktop PCs, 1 wireless desktop PC, 3 wireless laptops, and 1 wireless printer.
I am at a loss to understand what the problem is. Comcast is no help with their free support. They want me to pay if I want additional help.
