Slow speeds troubleshooting


We can confirm 100% that Crisp Fibre does not shape, throttle, discriminate or degrade network performance based on content or usage. All our packages are premium packages. You will always get a full-speed connection from Crisp Fibre. Slow internet speeds can be caused by numerous factors.

Below is a guide to help you determine where the issue could be and how to resolve these issues.

We will need your help to determine if the issue is with the Wi-Fi signal being broadcast from the router or if the router is bad or damaged, or if the Fibre connection coming into your home is bad or damaged.

Please can we also, if possible, very kindly request that if you are working from home, you will need a very stable connection. Network cable or Lan cable is always recommended and will always give you the best possible connection to the router and the internet and will eliminate the issue of Wi-Fi signal and Wi-Fi coverage problems.

When your devices use Wi-Fi to connect to the Internet the signals are sent with radio waves and despite all advanced features, wireless interference can happen. As a result, your wireless connection to the device you are having issues with may become weak and unreliable.

The reasons for these things are many:

Routers placed in corners, near the ground, and behind walls of concrete, metal, or wood make it hard for the signal to pass and can create dead zones in your house.

Things that can block Wifi signals

Household electronics operate often on the same wireless band, causing disruptions to the Wi-Fi signal while those household electronics are in use.

Drain on Wifi bandwidth

Things like aquariums and mirrors reflect radio waves and can act as a barrier to Wi-Fi signals.

Factors that affect internet speed


Placement of your router matters. Wi-Fi can be badly affected by the following.

Try to keep your router clear and away from the following:

  • Thick concrete Walls - Double-story homes.
  • Kitchen appliances - Microwaves.
  • Aquariums, glass, and mirrors.
  • Baby monitors and old cordless home phones.
  • Home entertainment sound equipment, speakers, soundbars, and subwoofers.

Where to Place Your Router for the Best Wi-Fi Signal:

  • Put it in a central location. A radio signal doesn't just broadcast in one direction.
  • Place the router in a higher position and away from items that can block the Wi-Fi signals.
  • Cut down on walls and stay away from windows.
  • Clear the obstacles around the router.
  • Avoid interference and noise.
  • Reposition those antennas.
  • Also please try and do not place 2 routers that both broadcast Wi-Fi signals next to each other.

Another very important aspect that can cause Wi-Fi issues is if your router is old or outdated and cannot keep up with the demand. The best practice would be to replace your router with approx. every 3-4 years due to Wi-Fi technology always changing and getting better and your devices requiring more bandwidth. If your router is three years or older, please consider replacing and upgrading the router.
