I have had to turn off the firewall on my wife's PC to stay connected to the internet. When the firewall acts up the WAN is not accessible. The LAN still works. I have tried re-booting the PC, the router, and the modem to no avail. I tried a different network adapter. When I try to ping an outside address, I get a general failure error. This is with a name or IP address. I am running Windows 7 32 bit. I have uninstalled and re-installed Shaw Secure. I really would like to be running a firewall on her PC. Shaw Secure disables the Windows firewall. This problem occurs every few days if the firewall is turned on. It has been off for a month now and no connection problems.
