I just had Verizon FIOS installed and have a home wireless network. Previously, I had cable internet with a Linksys router, never had problems, I could print wirelessly from my laptop and was able to share files from the desktop to laptop. The printer is connected via USB to the main desktop computer. Both machines run Windows XP. After the FIOS installation, I can access the internet with the laptop without problem, but I cannot print or access files from the desktop computer. I am not a beginner to computers and have tried everything I know for finding the printer through the laptop without success. I use Norton Internet Security, same as I had with the pre verizon network. Printer sharing is enabled and the main hard drive on the desktop is shared out as well.
