Ever since I changed from a PCI ADSL modem to an ADSL router (or maybe it's just a coincidence), whenever I try to do a Norton update, I get an error message from Norton saying "cannot connect to your ISP". Daft, I know, since I am already connected. I have tried disconnecting the router, and re-plugging in the modem, and trying again, and I have also tried switching off Zone Alarm (even though Norton worked perfectly for a year with it switched on), but I still get the same error message from Norton. Any ideas ? Could it be anything to do with having two firewalls ? Or the switch from the modem to the router ? It's a bit worrying not being able to keep up to date.
