Fixing Ubuntu Wi-Fi connected but no internet access issues can be a frustrating problem, but there are several troubleshooting steps that can help.
One possible solution is to restart the Wi-Fi router. Simply unplug the power cord, wait for a minute, and then plug it back in. This can often resolve connectivity issues.
Another solution is to enable the wireless adapter on Ubuntu. You can do this by using the command “sudo lsusb” for USB adapters or “sudo lspci” for internal adapters. Enabling the wireless adapter ensures that it is properly recognized and utilized.
It is also important to choose the correct Wi-Fi connection when multiple networks are available. You can do this by clicking on the network icon on the desktop or going to System Settings and clicking Network. Selecting the right network ensures that you are connecting to the appropriate source of internet access.
If the issue persists, installing network drivers using the Ubuntu ISO image may help. The ISO image needs to be copied to the home directory and mounted using the command “sudo mount -o loop Ubuntu.iso /media/cdrom”. Then, the network drivers can be installed from the Ubuntu Software tab in Software & Updates.
In some cases, missing module drivers may be the cause of the problem. These can be installed by using the terminal command “sudo modprobe modulename” where modulename is the name of the chipset. Installing the necessary module drivers ensures that the Wi-Fi connection is fully supported.
DNS server configuration may also be a factor in the lack of internet access. Modifying the DNS settings can help resolve the issue. You can do this by using the command “nmcli device show wlan1 | grep IP4.DNS” and then adding the DNS servers. This ensures that your Ubuntu system knows how to properly connect to the internet.
Additionally, installing Network Manager or checking if it is already installed can help manage the Wi-Fi connections properly. This can be done by using the command “sudo apt install network-manager” in the terminal. Network Manager provides a user-friendly interface for managing Wi-Fi connections and can help diagnose and resolve any issues.
Finally, make sure that the Wi-Fi radio is turned on. Use the command “nmcli r wifi on” in the terminal to ensure that the radio is enabled. Sometimes, a simple toggle of the Wi-Fi radio can resolve any connection problems.
Overall, these troubleshooting steps can help fix Ubuntu Wi-Fi connected but no internet access issues. By following these steps and taking the necessary actions, you can restore a stable and reliable internet connection on your Ubuntu system.
