You know the drill you’re in the middle of downloading your favorite TV show or playing an online game with your buddies when suddenly, poof! Your connection disappears like a fart in the wind.
No worries, though, my dear Linux enthusiasts! We’ve got some tricks up our sleeves to help you troubleshoot this ***** issue.
Before anything else check if other devices on your network are experiencing the same problem. If they are, it could be an issue with your router or modem. In that case, give them a call and see what’s up. But if only you’re having problems, Let’s jump right into some Linux-specific solutions.
Step 1: Check Your Network Adapter Status
The first thing we need to do is check the status of our network adapter. To do this, open your terminal (or command prompt for Windows users) and type in “ifconfig”. This will display a list of all available network adapters on your system along with their current status. If you see something like “LINK DOWN” or “RUNNING NO CARRIER”, then that’s probably the culprit.
Step 2: Restart Your Network Adapter
If your adapter is showing as “DOWN”, try restarting it by typing in “ifdown [adapter name] && ifup [adapter name]”. Replace “[adapter name]” with the actual name of your network adapter (you can find this out using “ifconfig”). This should bring your adapter back online.
Step 3: Check Your Network Configuration
If restarting your adapter didn’t work, it could be an issue with your network configuration. To check if everything is set up correctly, type in “cat /etc/netplan/*.yaml” (or “.conf” for older versions of Ubuntu). This will display the current network configuration on your system. If you see anything that looks out of place or incorrect, try editing it and running “sudo netplan apply”.
Step 4: Check Your DNS Settings
If everything else seems to be working correctly but you’re still having issues connecting to websites or servers, check your DNS settings. To do this, type in “cat /etc/resolv.conf” (or “/etc/netplan/*.yaml” if using newer versions of Ubuntu). This will display the current DNS server(s) being used by your system. If you’re having issues connecting to specific domains or servers, try changing your DNS settings to a different provider like Google DNS (8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1 and 1.0.0).
Step 5: Check Your Firewall Settings
If you’re still having issues, it could be an issue with your firewall settings. To check if everything is set up correctly, type in “sudo ufw status”. This will display the current state of your firewall (if using UFW). If you see anything that looks out of place or incorrect, try editing it and running “sudo ufw enable” followed by “sudo ufw allow [port number]”.
Step 6: Check Your System Logs
If all else fails, check your system logs for any errors or warnings related to your network adapter. To do this, type in “tail -f /var/log/syslog | grep ‘net’”. This will display the last few lines of your syslog file and filter out anything that doesn’t contain the word “net”. If you see anything suspicious or concerning, try searching for a solution online.
