1) When it was 'activating' my account, it hung on the last page, giving me a white screen. But when I tried to load a web page, it actually loaded. So it seems that I am activated. And yet . . .
2) Random images do not load correctly, giving me DNS Lookup Errors:
This webpage is not available
The server at view.atdmt.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.
I would heartily appreciate your help.
I ran debugging on the router, and DNS performed fine. I tried using Google's Open DNS, and same problem. I'm not sure that I used Google's dns correctly, however. I also tried restarting the router. None of that worked.
