Internet Troubleshooting : SLOW

(If no issue detected from NBN)

🧪 1. Basic Troubleshooting
​
✅ 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.
✅ 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.
✅ 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
​
✅ 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.
✅ Disconnect Unused Devices
  • Too many connected devices (especially those streaming or downloading) can impact network performance.
✅ Check Network Adapter Health (Windows)
  • Open Device Manager and ensure there are no warning icons on the network adapter.

🧭 3. Software & Settings
​
✅ Close Background Apps
  • Applications like OneDrive, Dropbox, or video conferencing can use a lot of bandwidth.
  • Press Ctrl + Shift + Esc to open Task Manager → Check the Network column.
✅ Disable VPN or Proxy Temporarily
  • VPNs can reduce internet speed. Disable them if active and test again.
✅ Flush DNS Cache
  • Open Command Prompt and run:

📡 4. Wi-Fi Optimization
​
✅ Move Closer to the Router
  • Wi-Fi signal weakens with distance and walls. Try sitting closer to the router.
✅ 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.
