We have Xfinity which comes with Constant Guard security system. I installed it and everything worked great - never had to remember passwords for each function etc. Then, it stopped working. I tried to uninstall and reinstall, but it would never get all the way through the reinstall before failing. In the mean time, my computer settings changed and it no longer 'remembers' settings when you use the check box for remember on this computer. Where do I change that back? Any suggestions for reinstalling constant guard?
