Long story here: A few weeks ago, I lost internet connectivity on my desktop PC at work running Windows 11. I checked Firefox, Edge & Chrome but couldn't access any site. It took a few hours and a lot of updating Windows, rebooting each time the internet kicked out, but I got it to work again. Fast forward to this past Monday the 29th when the issue happened again. Within roughly a minute, the internet just died on my desktop again. I grabbed my work laptop, also running Windows 11: same issue happened within 60 seconds. I checked Firefox on a desktop running Windows 10 - had no issues at all. Today, I installed Firefox on another laptop (the same model at the other one) running Windows 11. As soon as it synced my account, the internet stopped working. I though it may be the Sync option, so I reinstalled Firefox on my laptop but did not log in to Sync - the same issue: dead internet within 30 seconds now. I have: * Run anti-virus * Run network diagnostics and reset * Rebooted a multitude of times * Uninstalled, reinstalled at least twice * Run troubleshooting in Firefox (which I cannot attach the logs due to it being uninstalled right now) * Checked to make sure my modem/routers are working right (no one else in the building has this issue and we all use Firefox, but none are synced to my account) * I even asked my company's tech team (who are mostly software developers) and they said No, sorry, we don't help with that (wonderful right?) I've attached a screenshot of the OG machine's information. Not sure if it will help at all, but it's worth a shot.
