I seem to have a wireless connectivity problem that goes back to Windows files and I would appreciate any advice anyone can provide:

 

Running Win XP Home, Linksys Wireless Router and my ISP is Cablevision...... the problem is that I cannot connect to the internet.  Did all the troubleshooting that can be done and even with a direct cable connection to my computer I cannot get internet access.  Everyone seems to think that I have corrupted Winsoc files in Windows.

Is it possible to repair these files? and if so, how do I go about it?

Thanks in advance for any help anyone can provide!!
