• Limited Ethernet ports: If your router has limited Ethernet ports or it’s impractical to run cables to all your devices, Wi-Fi may be the only option.
• Occasional streaming: If you only stream occasionally and are willing to tolerate occasional buffering or lag, Wi-Fi may suffice.
• Strong Wi-Fi signal: If you have a modern router and a strong, stable Wi-Fi signal, the difference between Wi-Fi and Ethernet may be negligible for some streaming activities.

Choosing the Right Ethernet Cable

If you decide to use Ethernet for streaming, selecting the appropriate cable is important. Here’s a brief overview of common Ethernet cable categories:

• Cat5e: Suitable for basic networking and streaming, supporting speeds up to 1 Gigabit per second (Gbps).
• Cat6: Offers improved performance and reduced crosstalk compared to Cat5e, supporting speeds up to 10 Gbps at shorter distances. Ideal for demanding streaming applications.
• Cat6a: Provides even greater shielding and performance than Cat6, making it suitable for high-bandwidth applications and environments with significant electromagnetic interference.
• Cat7: Offers superior shielding and performance, supporting speeds up to 10 Gbps over longer distances. Less common in residential settings.
• Cat8: The latest standard, designed for data centers and high-bandwidth applications, supporting speeds up to 40 Gbps.

For most home streaming setups, Cat6 or Cat6a cables offer the best balance of performance and cost.

Optimizing Your Streaming Experience, Regardless of Connection Type

Whether you choose Ethernet or Wi-Fi, several steps can optimize your streaming experience:

• Update your router firmware: Regularly updating your router’s firmware can improve its performance and security.
• Minimize network congestion: Reduce the number of devices using your network simultaneously, especially during peak streaming times.
