Fibre - Troubleshooting slow internet speeds

Slow internet speeds could be caused by a variety of reasons and so it is important to systematically work through all steps below to determine where the problem lies.



Perform a Speed Test


The first thing to do is perform a simple speed test to find out what speeds you are getting. Bear in mind that all internet lines are best effort services and it is unlikely that any line will achieve the maximum line speed at all times.

Open your internet browser.

Close down all other applications including Peer 2 Peer, Torrents, FTP and other similar services. Restart your PC first if you’re not certain.

It’s best to perform your speed test with the network cable plugged into your PC and router instead of using your Wi-Fi connection.

Record the results for comparison.


Troubleshooting

Now that you have your exact speeds recorded, it’s time to start troubleshooting.



Testing via Ethernet helps isolate the connection to see if the problem is over WiFi.



Troubleshooting the router :


  • If possible, plug in a different router into your Fibre box (CPE) and run another speed test by clicking here.
  • A hard reset of the router can also be done to ensure the router may not be playing up, this also helps alleviate any software related issues, you would need a pen or paper clip and insert and hold this in the reset pin at the back of the router for 30 seconds, the lights should flash and the router will automatically restart itself, you would then need to login to your router by heading into your browser and type in 192.168.0.1 and using admin as the username and password for the router interface to update your settings for your connection.
  • If a different router gives you improved speeds, the first router may be faulty and may need to be replaced. If a different router also gives you slow speeds then it’s safe to say that the original modem isn’t faulty.

Test each device: 

  • Has your speed improved? If your speeds go back to normal when you have just one computer connected to your router, you can start plugging your other equipment back in, piece by piece.
  • Start with any phones or wireless devices you are using.
  • Wait a minute or two after each device is plugged in, and then run another speed test.
  • If your speed suddenly drops, the cable or device you’ve just plugged in is probably affecting your speeds.
