2. Select your Wi-Fi network.
3. Enter the passphrase.
4. Disconnect Ethernet.

For command-line users, use nmcli:

nmcli device wifi list
nmcli device wifi connect "YourSSID" password "YourPassword"

To disable Ethernet via terminal:

nmcli device disconnect eth0

Replace eth0 with your actual interface name, which you can find using ip link.

Configuring Your Router

Getting the best wireless experience requires proper router configuration. Here are key settings to check:

• Band selection: Use 5 GHz or 6 GHz for speed; 2.4 GHz for range.

• Firmware updates: Keep your router firmware current for security and performance.

Access your router’s admin panel by typing its IP address (usually 192.168.1.1 or 192.168.0.1) into a browser.

Ethernet vs Wi-Fi Comparison

Understanding the differences helps you decide when Wi-Fi is appropriate and when Ethernet might still be better.

Feature	Ethernet	Wi-Fi
Speed	Up to 10 Gbps (stable)	Up to 46 Gbps (Wi-Fi 7, theoretical)
Latency	Very low (1-2 ms)	Low to moderate (5-30 ms)
Reliability	Excellent	Good (depends on environment)
Mobility	None (tethered)	Full mobility within range
Setup	Requires cable	Wireless, no cables
Interference	Minimal	Susceptible to walls, devices
Security	Physical access needed	Encryption required (WPA3)

For most home users, the trade-off is well worth it. Power users and gamers may still prefer Ethernet for critical tasks.

Optimizing Your Wi-Fi Signal

After you learn How to Use Wifi Instead of Ethernet?, the next step is making sure your signal is strong. Weak Wi-Fi can be frustrating, but simple adjustments help:
