What can affect broadband speed

Broadband performance depends on the service reaching your router and the equipment connecting your devices. Understanding the difference helps you improve the right part of your home network.

Wi-Fi signal and interference

Distance, walls, floors, metal objects and nearby wireless networks can affect Wi-Fi. Keep the router in an open position and compare a test close to it with one in another room. A faster broadband package alone will not resolve a weak wireless signal.

Ports, adapters and device capability

The router’s Ethernet port, your device’s adapter and its processing capability can limit throughput. For multi-gigabit broadband, all parts of a wired test need to support a suitable link rate. A Wi-Fi 7 router also needs a compatible client to use Wi-Fi 7 features.

Shared use and background traffic

Streaming, large downloads, video meetings and cloud backups share your connection’s capacity. Test with those activities paused to understand the baseline. A VPN, remote server or the application you are using can also affect results.

Broadband service or home network?

Compare Ethernet with Wi-Fi, then repeat the same test at different times. If the wired connection performs well, focus on wireless coverage and device settings. If both remain below your expected service range, contact Exascale with the results.
