Check Router: Ensure that the router is functioning well by connecting another device. If the issue is with the router, restarting it may help.
DNS Issues: Sometimes, your DNS settings may cause connectivity problems. You can change your DNS by going to system settings. Navigate to “Settings” > “Network” > click your WiFi connection > “IPv4” and choose “Automatic (DHCP) addresses only.” Here, you can specify Google’s DNS (8.8.8.8 and 8.8.4.4) in the “DNS” field.
Advanced WiFi Settings in Ubuntu
Once your WiFi is running smoothly, you might want to delve into advanced settings to optimize your connection or customize your network preferences.
Managing Network Settings
You can access advanced network settings through the same network menu where you enabled WiFi. Click on “Settings,” and you will find several options such as:
Connection Priorities: You can prioritize certain connections over others by dragging them in the list.
IPv6 Settings: If you want to enable or disable IPv6, you can find that option under the “IPv6” tab in your connection settings.
Security Settings: Modify security protocols used for your WiFi connections, such as WPA, WPA2, or open networks.
Setting Up a Hotspot
If you wish to share your Internet connection with other devices, creating a hotspot in Ubuntu is a great option.
- Go to “Settings” > “WiFi” > “Use as Hotspot”.
- Configure your hotspot name (SSID), password, and other options.
- Click on “Turn On” to activate the hotspot.
This feature is beneficial if you’re using a mobile Internet connection on a laptop or need to provide Internet access to other devices.
