I've run into a tricky problem after booting into Windows 11 for the first time in a while. I have a dual-boot setup with Ubuntu LTS on one HDD and Windows 11 on an SSD. I mainly use Ubuntu, but I booted Windows recently for a project in Reaper and now my Ethernet and WiFi connections are messed up. They show as connected, but I can't access the internet. I've already disabled fast boot on Windows and tried various boot methods, but nothing seems to bring my connections back when I switch to Ubuntu. Is there anyone who can help me troubleshoot this?

Make sure to double-check that Fast Boot is actually disabled. Sometimes settings can get flipped without you knowing. And like others suggested, try rebooting your router. It's a simple step that often fixes these connectivity issues, even if it seems unrelated to your Linux setup. Good luck!
You might want to check if Secure Boot was on when you installed your systems. That's been known to cause issues. In addition, reboot your router—it could be playing tricks with your connection even though Windows still works. If you haven't already, try booting from a Linux live USB to see if that connects. And it's good you're aware of fast boot; it can definitely mess with dual-boot setups. Just make sure it's fully disabled!
Thanks for the tips! I never considered the router or Secure Boot, so I'll look into those as well.
Honestly, it looks like something in your Linux setup could have gone wrong because Windows itself doesn't usually interfere with it. Windows lacks the necessary drivers to mess with Linux filesystems, so I would tackle this from the Linux side more. It's weird that it failed after booting Windows, but I'd recommend focusing on fixing things within your Linux install.
I don't know; everything worked great until I booted into Windows. It’s why I suspect it might be related.
I really appreciate the advice! I’ll do both of those and hopefully get it sorted.
