Guys, I am having this problem. I can't access the Internet when I am behind the wireless router.
Observations:
1) The TP Link WT340GD wireless router is accessible by ethernet. I can type
http://192.168.1.1/ and I get to configure the router.
2) The router status shows that it picks up the dynamic IP address assigned by the Webstar SCIENTIFIC ATLANTA DPC 2100 series Cable Modem.
3) The DNS is automatically assigned by the ISP, and the DNS setting of computer on the ethernet is also set to automatic. (The wireless router runs the DHCP on the ethernet/WLAN)
4) My laptop picks up the network but can't access the Internet. This inspite of router being assigned the IP address by the cable modem.
5) The PC on the network also fails to connect to the Internet.
Guys, help!
