I have a client with a Dell Vostro 320 All-in-One PC running Windows 7 Home Premium. It had gotten hit with some malware and was running very slowly and was unstable. I decided that backing up his data and restoring back to factory defaults would be the best approach for giving him a relatively fast, stable machine. I brought the PC to my home and ran the Dell System Restore to get it back to factory default settings. Then I downloaded & installed all available OS updates and patches. While at my home I was connected to my Time-Warner cable connection via Ethernet cable.
After installing all necessary software and restoring his data, I brought the PC back to his home. I plugged it into the Verizon DSL Modem (a Westell Model 6100) and booted up the PC. The problem is that when I try to launch a webpage, the browser gets stuck indefinitely loading and goes nowhere. It never gives a "page not found" or Connection Time-Out error. The browser just spins and spins but never finishing loading. This is happening in IE, Firefox & Chome.
I called Verizon DSL support and they ran a line test that shows the connection is solid. However, we are unable to get a page to load in either IE, Firefox or Chrome.
So what could be preventing the web pages from loading all while not getting timeout or "page not found" errors? The Verizon tech had us reset the Westll 6100 modem, but this did not help. Windows Firewall is enabled, so i tried disabling it. Didn't help. I can ping various websites from the command line and they all reply back normally.
I had decided that something had gone wrong with the Westell modem. However, I connected the client's Acer Aspire netbook (running Win 7 Starter) and the netbook has no problem loading webpages. So the problem is not the modem. It has to be some configuration issue on the Dell PC. I just don't understand. Everything was fine when using my Time Warner connection at my home.
Hoping I can get some guidance on how to resolve this problem. Thanks in advance.
