We purchased a new computer with a Dell V525w printer over a month ago. The printer installed correctly via wireless and everything worked great, but all of the sudden it will not stay connected via wireless and the computer will not find it at all on the device list. After 3 hours of trying to get it to work via help and troubleshooting tools, I have given up. I have uninstalled, re-installed, tried all of the wireless tricks, but to no avail. My wireless network does show it is connected, but don't know why it all of the sudden stopped working. I have the McAfee virus software that came with the computer running, so I don't know if that is the culprit.
