Hello Everyone, i understand that this thread is old, i posted this just in case someone is reading, or having the same problem.
Ive been having this problem for a while now, and i think i figured it out,
if youre able to ping the site , ( click Start->Run-> Type CMD-> then type: ping www . website you want to check .com)
If you get something that looks like this:
Reply from 64.233.161.104: bytes=32 time=106ms TTL=245
Reply from 64.233.161.104: bytes=32 time=79ms TTL=245

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:

Then your modem is able to acces the site.
If so, then try accessing the site using a proxy, not all of them work well,
try:
www.proxify.org (although its not free for some features)
http://www.filterbypasser.com/ ( i use this and it works for me!)
Hope this works for you, and Good Luck!
