After installing my new DAP-X1870 extender using the WEB interface for setup, I can sign-in to the extender channel and get connected but there is no Internet connection. My Arris TG2482A WiFi Router has full Internet connectivity as well as all my WiFi devices(PC,Tablet,Phone). The lights on the extender are all green and the WiFi signal is strong in 3 different locations in the house. My question is why only the extender doesn't get a Internet connection when everything else does. I have taking the following steps to troubleshoot the problem:
1) Flushed the Windows DNS
2) Disabled the Windows Firewall on my PC
3) Changed the extender channel from 1 to 6
I posted this problem first before I decide to reset the extender back to factory defaults and start over. Any suggestions are welcome.
