I sure hope you can help me. I have reached the end of my tech expertise. I am having trouble connecting to the internet on my main computer (Dell XPS 400 running Windows XP and a Westell 6100 modem); I can get online through the wireless lan on my laptop which is connected via wireless Netgear Rangemax router. I finally removed a virus/malware that McAfee didn't stop (Microsoft Security Alert phony), so thought I did. In the process of removing it (thanks to Malwarebytes' Anti-Malware), files were removed and/or quarantined; those files apparently contained information that allowed the coputer to "obtain IP address" as well as the subnet mask, default gateway, DNS server, and alternate DNS server. I manually entered those numerals, but still cannot access the internet from my main computer.
My Microsoft gateway diagnostic said "could not get proxy settings via the Automatic Proxy configuration mechanism" and "The default gateway address could not be resolved via ARP" The IP Layer Diagnostic said "The default route is valid. The loopback route is valid. The local host route is valid. Invalid ARP cache entries"
The WinSock diagnostic said "Provider entry RSVP UDP Service Provider could not perform simple loopback communication. Error -1" and "A connectivity problem exists with a base winsock provider"
The HTTP, HTTPS, FTP Diagnostic says: "Warn FTP (Passive): Error 12007 Connecting to ftp.microsoft.com: the server name or address could not be resolved. Warn HTTP: ERROR 12007 connecting to www.microsoft.com: The server name or address could not be resolved. Error Could not make an HTTP connection
Error Could not make an HTTPS connection
Error Could not make an FTP connection"
