I have had, for several years, Sygate Personal Firewall Pro as my firewall. A month or so ago I started having connectivity problems. An icon in the system tray revealed the following: Local Area Connection 3 Speed: 100.0 Mbps Status: Limited or no connection "Network did not assign a network address to the computer" I spoke with Verizon to no avail. I was told there was a problem with the firewall. I disagreed with the Verizon representative but uninstalled the Sygate program and implemented the Windows firewall. After doing so I no longer had connectivity problems. After a few days I reinstalled the Sygate program and the connectivity problems came back. I again uninstalled the Sygate program and went back to the Windows Firewall. I have downloaded the Comodo Firewall, free version, and intend on installing it within the next few days. However, if the Sygate connectivity problem could be resolved I would really prefer to keep Sygate. Hopefully, someone out there will have an answer. I want to express my appreciation to those who might reply. Thank you very much in advance.
