Hello, Well I have a very strange problem. I have a laptop HP6730S and I can't log in to the internet from my home. Anywhere else I can connect..if I go to the net cafe I can log in or to any other place I can log in but not here. I have a PC and the it's perfectly connected, but when I try to connect with the lappy I get the msg that Acquiring network address but it never get connected. The network card green light doesn't flicker. On my TCP/IP properties I've clicked automatically obtain network address, and everything else seems to be right. I've tried everything but no solution. Has anyone have any suggestion as a solution for this strange problem? THNX
