Update Router’s Firmware

Regular firmware updates can provide enhancements to speed and security. Visit the support section on Xfinity’s website for guidance on how to update your specific router model.

Manage Your Devices and Connection

Another technique on how to increase upload speed Xfinity is by managing your devices and their connection.

Connect via Ethernet Cable

An Ethernet connection provides a stable and speedy link to the internet, often outperforming WiFi. If possible, connect devices directly to your router using Ethernet cables, especially for activities requiring large upload bandwidth.

Most routers allow users to set Quality of Service (QoS) settings that prioritize bandwidth allocation. For instance, you can prioritize video conferencing applications if you often work from home.

Close Unnecessary Applications

Some applications or software updates may run in the background and guzzle your upload speed. Close unnecessary apps and disable automatic updates when performing crucial tasks.
