🚀 Understanding NBN Speeds, Performance & Congestion

Last updated on Feb 06, 2026

Why Internet Speed Varies

Internet performance is affected by:

  • Time of day

  • Number of connected devices

  • Type of applications in use

  • Wi-Fi vs wired connections

  • Network congestion

Speed results are not fixed values and can fluctuate.


Common Causes of Slow Performance

  • Heavy uploads or downloads

  • Cloud backups during business hours

  • Wi-Fi interference

  • Outdated routers

  • Building cabling issues


Wi-Fi vs Ethernet

Wi-Fi speeds are often lower than wired speeds due to:

  • Distance from router

  • Interference

  • Device limitations

For testing and critical services, a wired Ethernet connection is recommended.


When to Troubleshoot

If slow speeds:

  • Are persistent

  • Affect multiple devices

  • Impact business operations

Pickle can guide troubleshooting and escalate if required.
