Norton blocks all Internet access

Issue abstract:

Detailed description: About every three days, my desktop PC (Dell Tower) loses all connection to the Internet; neither Ethernet nor Wifi works. When I have the issue, I can’t “ping” any external sites, or even my DNS server. On one of these occasions, SpeedTest worked when nothing else did; but since then, not even SpeedTest worked. It’s not my router (all the other Internet devices in my house work quite OK); I have uninstalled / reinstalled Norton twice. When it happens, I disable all Norton features, including virus protection and smart firewall, and this does not restore access. Possibly related symptom: every few days, Norton thinks I’m on a new network and scans the network. Any thoughts??? I am just about to switch to a different security product if I can’t get Norton to work.

Product & version number: Norton 360 25.5.10141 (build 25.5.10141.934)

OS details: Windows 11 with Windows Update turned on

Utilisez-vous Norton Secure VPN ?

I have not been using Norton Secure VPN. I turned it on this morning to see if it helps.
