    The new modem promised from Verizon will be a modem/router, so it may have NAT configuration. When she gets it, I'll set it up for her along with TeamViewer. Who knows, maybe this new modem will be the solution for her. Could it be that her old modem is experiencing some slight power fluctuations, and her tower is sensitive to it, while my laptops are not?

    I would not expect power issues to manifest themselves that way.

    When you took the computer back to her home the first time, did it turn into a pumpkin right away or hours later?

    Immediate pumpkin. While it was a greyhound with my equipment, it turned into a snail at her house. (I couldn't make the fruit analogy work any more). My Windows 7 laptop was a greyhound with both modems. And no, I would not expect power issues to exact that type of behavior either, but I have no alternate explanation.

    When I asked if her computer was behind a NAT - I was grasping at the very unlikely possibility that someone on the internet broke into her old modem and setup a filter that only allows traffic to/from Google. If there is a NAT, then there is often filtering by MAC address and/or IP address. Your laptop would not be impacted by such a filter.

    Or maybe she has a prankster in her life that setup a filter while visiting her...

    I've heard about comparing apples and oranges, but pumpkins and greyhounds is a new one

    I'm sorry, but if someone broke into her old modem and set up a filter that only allows Google traffic, then both of my laptops should have experienced the same connection problems when connected to her modem. They did not.

    And yeah, I could think of no fruit analogy that was the opposite of turning into a pumpkin.

    No - the filters are MAC address specific.

    Your laptop has a different MAC address and thus would not be filtered.

    Well, you've obviously exceeded my level of knowledge with that one. Am I correct in assuming that a new modem should resolve any such issues?

    Yes - a new modem would remove any filtering that was setup inside of the old modem. Time well tell.

    MAC or IP filtering is very unlikely to be the cause - but it fits the symptoms - so I had to go there. It is possible (but again, unlikely) to have this filtering caused by software installed on the desktop computer. I've seen security related products that identify each network. It could have one set of rules for her home's network and a different set of rules for your home's network. But, when you had the computer in your home, you should have seen some sort of popup indicating that the software detected a new network - then the security software would ask you how you wanted to setup restrictions for this newly discovered network.

    If a new modem does not fix the problem, then we move on to these steps: Troubleshoot Application Conflicts by Performing a Clean Startup

    Thanks for your replies. If it makes any difference, when I had her PC at my house it was never connected to a stand alone modem. A few years ago after my modem died I was sent a new combination modem & router unit from my ISP, so I was forced to disconnect my personal router. And when I connected my friend's PC to my modem/router I never received any indication that a new network had been detected.

    How or if any of this ties into the connection problems at her house is a question I cannot answer...

    I am also not computer savvy enough to have a clear understanding of MAC address filtering. In my mind it had something to do with wireless security, and it was an additional protocol you could set up through your router. Since my friend has no router, I fail to grasp the significance of this whole filtering issue.

    She'll probably get her new modem early in the week and I'll report back to you good folk after I hook it up for her. Since Verizon doesn't want her old modem back, maybe I'll bring it to my house.

    Problem resolved - the new modem / router took care of the problems.
