A lady brought her PC to my house to work on for her. Part of my work, was to download and install the latest updates from Microsoft. In addition, I download a virus scan program and ran it.
When I finished, she dropped by to pick the computer up. Back at her house, she called me because apparently she has no internet there. At both locations, she's using a wired connection. Here, I was running through a router; at her house, she plugs directly into a cable modem that also offers phone service. I knew the Internet was working here at my house so I walked her through some simple fixes - Checked cable connection on the back of the PC (connection was good and she said the little lights were flashing), told Windows to repair the connection (couldn't find anything wrong), tried rebooting the modem (apparently her modem has a built in backup battery because she said when she unplugged it from the wall that the power light kept flickering on and off slowly so I'm not sure the modem was actually reset), tried the connection repair in the command prompt with the IPCONFIG /RELEASE and IPCONFIG /RENEW commands (she got an IP address, but it seems like a strange one to me - figured it would be a 192.168 number but it isn't), wanted to try using another NIC on the back of the PC (she only has one). Since I was unable to fix it over the phone, I told her I would ride out to her house tomorrow to take a look at it myself. I also asked her to call the ISP to make sure the trouble isn't on their end. They told her they couldn't find anything wrong on their end and that it was, in fact, her PC that's messed up.
I think at some point, she MAY have mentioned that she saw a message about DNS but I could be getting this issue confused with another incident.
Just wondering if any of you can think of anything else I can check so I'll be ready when I arrive tomorrow. I am going to have a good look at that modem though and see if I can get it to reboot properly.
Any and all information will be greatly appreciated.
