Upgrading an operating system is always exciting, as it usually comes with new features, security patches, and performance improvements. However, sometimes the process does not go as smoothly as expected. A common issue many users have reported after upgrading Nobara 41 to Nobara 42 is that their internet connection suddenly stops working.
If you’re facing this problem, don’t worry — it’s usually related to network drivers, kernel updates, or misconfigured settings. Below, we’ll explore the most common causes and step-by-step fixes to get your internet back online.
When you move from Nobara 41 to Nobara 42, certain components of the system are updated, which can impact connectivity. The most common reasons include:
Open a terminal and run:
nmcli deviceThis command lists all network devices. If your Wi-Fi or Ethernet adapter is missing, it indicates a driver or kernel module issue.
Sometimes, the network service doesn’t start correctly after an upgrade. Restart it using:
sudo systemctl restart NetworkManagerAfter restarting, try reconnecting to your network.
If your adapter is not detected, reinstalling drivers may solve the issue.
For Intel Wi-Fi adapters
sudo dnf install iwlwifi-firmwareFor Broadcom adapters
sudo dnf install broadcom-wlThen, reboot your system.
It’s possible that after upgrading, some required packages were not fully installed. Run:
sudo dnf update --refresh
sudo dnf upgradeThis ensures all dependencies, including network-related ones, are up to date.
If you are connected to Wi-Fi but unable to browse, firewall or SELinux restrictions may be causing the problem.
Check firewall status:
sudo systemctl status firewalldIf necessary, temporarily disable it
sudo systemctl stop firewalldCheck SELinux
sestatusIf it shows enforcing, try setting it to permissive temporarily:
sudo setenforce 0If nothing works, resetting network settings may resolve conflicts:
nmcli networking off
nmcli networking onOr delete and re-add your connection:
nmcli connection delete <connection-name>
nmcli device wifi connect <SSID> password <your-password>If the issue is due to a kernel update, you can boot into the previous Nobara 41 kernel to check if networking works:
If the internet works with the old kernel, you’ll need to wait for a patched driver in Nobara 42 or manually install the correct one.
Losing internet connectivity after upgrading from Nobara 41 to Nobara 42 can be frustrating, but in most cases, the issue lies with drivers or network manager configurations. By checking adapter detection, reinstalling drivers, updating system packages, and resetting network settings, you should be able to restore your connection.
If none of the above methods work, you may need to report the issue on the Nobara Project forums or GitHub so developers can provide a patch for your specific hardware.
A smooth upgrade should improve your system, not break it — but when things go wrong, the fixes above will help you get back online quickly.
Q1. Why did my internet stop working after upgrading to Nobara 42?
This usually happens due to driver incompatibility, kernel changes, or misconfigured Network Manager settings after the upgrade.
Q2. How do I check if my Wi-Fi adapter is detected in Nobara 42?
Open a terminal and run nmcli device. If your Wi-Fi card doesn’t appear, it means the driver is missing or not loaded.
Q3. How can I reinstall Wi-Fi drivers in Nobara 42?
Depending on your adapter, install firmware using sudo dnf install iwlwifi-firmware for Intel or sudo dnf install broadcom-wl for Broadcom devices.
Q4. My device connects to Wi-Fi but I can’t browse. What should I do?
This could be a firewall or DNS issue. Try disabling the firewall temporarily or reset network settings with nmcli networking off then nmcli networking on.
Q5. Can I roll back to the previous kernel if nothing works?
Yes, reboot your system, open the GRUB menu, and select the older kernel from Nobara 41 to restore internet until a permanent fix is released.
