Internet Troubleshooting : SLOW

(If no issue detected from NBN)

πŸ§ͺ 1. Basic Troubleshooting
​
βœ… Check Other Devices
  • Is the slowness happening on one device only or multiple devices?
    • If it’s one device, it may be a local issue with that machine.
    • If all devices are affected, the router/modem or internet service could be the cause.
βœ… Run a Speed Test
  • Visit speedtest.net or fast.com and test:
    • Download speed
    • Upload speed
    • Ping/Latency
  • Compare these results to your expected internet plan.
βœ… Reboot Devices
  • Restart the device you're using.
  • Power-cycle your modem/router:
    • Unplug for 30 seconds, then plug back in and wait 2–3 minutes.

🌐 2. Network Connection Checks
​
βœ… Switch Between Wi-Fi and Ethernet
  • If you're on Wi-Fi, try using a wired connection if possible.
    • This can help determine if the issue is Wi-Fi-related.
βœ… Disconnect Unused Devices
  • Too many connected devices (especially those streaming or downloading) can impact network performance.
βœ… Check Network Adapter Health (Windows)
  • Open Device Manager and ensure there are no warning icons on the network adapter.

🧭 3. Software & Settings

πŸ“‘ 4. Wi-Fi Optimization
​
βœ… Move Closer to the Router
  • Wi-Fi signal weakens with distance and walls. Try sitting closer to the router.
βœ… Avoid Interference
  • Devices like microwaves, baby monitors, and cordless phones can disrupt Wi-Fi.
  • Switch to a 5GHz network if supported, for better performance in short-range areas.
