Other causes include driver issues, hardware incompatibilities, or disabled network interfaces. In this article, we will discuss solutions to this error.
1. Disable/Enable the Network Connection
This issue can be caused by temporary glitches in the network stack or conflicts in IP addressing. Turning the network connection off and then on resets the network settings, allowing it to reconnect with the router and update its IP or DNS settings.
2. Disable Fast Boot (Dual Boot System)
Disabling Fast Boot in Windows can fix issues with Linux not connecting to the network. Fast Boot puts some hardware, like network adapters, in hibernation, which can stop Linux from starting them properly. Turning off Fast Boot fully resets hardware during startup, letting Linux set them up correctly.
3. Disable Connect Automatically for the Network
Sometimes, your device keeps trying to connect to networks that aren’t set up correctly or are unavailable, causing problems. Turning off the “Connect Automatically” option for a specific network stops these failed attempts. This way, you can choose the network manually when it’s working, avoiding issues and having more control.
4. Change DNS to DNSMASQ for the Network
Switching to DNSMASQ can make your system handle DNS queries faster. DNSMASQ acts as a simple DNS forwarder and cache, storing recent queries locally to speed up domain name resolution. This improves response times for repeated queries and helps avoid issues with slow DNS servers.
5. Correct Date/Time Settings of Your System
If the system clock is wrong, it can stop secure connections because SSL certificates need the correct time to work. Fixing the date and time makes sure certificates are checked properly, which can fix connection problems caused by this mismatch.
6. Delete Bluetooth Devices in Your System’s Settings
Sometimes, old paired devices can interfere and make it hard for your system to connect anew. Removing these unused devices resets the Bluetooth stack, helping your system focus on the new connection without past issues.
7. Blacklist Other Communication Devices
If there are any other communication devices like Bluetooth or additional network adapters active, they can interfere with your primary network connection. Blacklisting these devices helps remove conflicts, allowing the system to focus on the correct network interface and establish a stable connection.
8. Remove Network Drivers from the Blacklist
Sometimes, network drivers are blacklisted to avoid conflicts, but this can block needed drivers. Removing them from the blacklist lets the system load these drivers, allowing the right network interface to work.
9. Reinstall the Network Manager
Issues with network connections can sometimes be caused by a faulty Network Manager. Reinstalling it removes corrupt files or settings, restoring the system’s default network management.
10. Disable Power Management of the Network Card/Driver
Power management can disrupt network stability by turning off the network card to save power, especially on laptops. Disabling this ensures the network card stays active, preventing connection drops or activation failures, and maintaining a stable connection.
11. Disable Hardware Encryption by the Network Device
Sometimes, network devices have trouble with hardware encryption, causing connection failures. Disabling it lets the software handle encryption, fixing issues from driver or firmware limits.
12. Update the Kernel of Your Linux Distro to the Latest Build
Updating your Linux kernel is important because new versions often fix bugs, boost performance, and solve hardware compatibility issues that may cause network problems. An updated kernel may provide patches for driver issues or network stack problems.
13. Upgrade Your Linux Variant to the Latest Build
Keeping your Linux variant updated ensures you’re using the latest kernel, drivers, and network tools, which can fix bugs and compatibility issues. Upgrading to the latest version may solve problems with network drivers, hardware support, or configuration mismatches causing connection errors. If no solution has worked so far, consider reinstalling your Linux distro. Before doing so, try using the iwconfig command, update your system BIOS, or utilize the WICD network manager. Additionally, consider using IPV6 (Link-Local) or disabling TCP.
