My Wi-Fi network is slow. How do I make it faster?
Issues with your Internet?
Select Network scan in the tools section of the Fizz Wi-Fi app to diagnose and fix issues with your Wi-Fi network.
Reminder: Use the same credentials as your Fizz account to log into the app.
The speed of a wireless connection can be affected by several factors.
It is normal for the speed of a wireless connection to vary depending on, among other things, distance to the Wi-Fi modem, technology used by the devices, and Wi-Fi interference.
Restart your Wi-Fi modem
- Unplug the power cable on your Wi-Fi modem.
- Make sure all the lights on the modem are off once you have unplugged it.
- Wait ten (10) seconds.
- Plug your modem back into the electrical outlet. Expect a three (3) minute delay to allow your devices to reconnect to the Wi-Fi network.
It is more effective to restart your Wi-Fi modem by unplugging its power cable instead of pressing its power button.
Make note of the various sources of attenuation of your Wi-Fi signal
The waves in your Wi-Fi network may be attenuated by various obstacles and sources of interference, causing speed drops and partial or complete disconnections of your internet connection.
Sources of interference include:
- Nearby Wi-Fi networks
- Surveillance cameras
- Baby monitors
- Microwave ovens
Obstacles to Wi-Fi waves include:
- Construction materials (concrete, aluminum, etc.)
- Heated flooring
If you are unable to change your environment to limit sources of Wi-Fi signal attenuation, it would be better to use a network cable (RJ45).
A cable is included in the original box of your Fizz Wi-Fi modem.
Try accessing the internet using a browser, software or application
If the low speed is limited to one browser, one website or only one application, uninstall the browser or application from your device.
If the situation remains unchanged after you reinstall the browser or application, consult support for this particular product.
Here are some examples of web browsers you could use:
Microsoft Internet Edge (Explorer)
Make sure your equipment is capable of reaching the desired speed
Each subscribed device has a Wi-Fi standard. This standard represents the maximum speed that the device can reach.
Here is a list of Wi-Fi standards and their approximate speed:
Standard Frequency Maximum speed Reach Congestion Bandwith MiMo Supported Year of appearence 802.11a 5 GHz 25 Mbps Weak Low 20 MHz No 1999 802.11b 2.4 GHz 5 to 6 Mbps Acceptable High 20 MHz No 1999 802.11g 2.4 GHz 20 to 25 Mbps Acceptable High 20 MHz No 2003 802.11n 2.4 GHz 30 to 110 Mbps Good High 20 or 40 MHz Yes 2009 802.11n 5 GHz 50 to 180 Mbps Good Low 20 or 40 MHz Yes 2009 802.11ac 5 GHz 90 à 400 Mbps Good Low 20, 40 or 80 MHz Yes 2014
Standards A, B and G are now obsolete based on average use.
A Wi-Fi network can be compared to a highway. Devices that use obsolete standards are like a vehicle that slows down an entire lane.
Different devices supporting the same Wi-Fi standard may not all have the same maximum speed.
Only the latest, state-of-the-art devices will be able to reach maximum speeds.
Consult the manufacturer’s datasheet to see which standard your device is using.
If the band steering function on your Wi-Fi modem is turned off, in most cases it’s preferable to manually select the 5GHz Wi-Fi frequency band.
If allowed by your device, connect to the 5 GHz Wi-Fi frequency
Your Fizz Wi-Fi modem uses by default the frequency band steering technology. When this function is disabled, the Wi-Fi modem will display two (2) frequency bands, 2.4 GHz and 5 GHz. Manually select the 5 GHz from your devices.
The modification of this option is possible thanks to the Fizz Wi-Fi app:
- Choose: ''My Wi-Fi''
- Go to the settings (gear wheel icon)
- Activate/Deactivate the Band steering option
The Fizz Wi-Fi app is available for free on:
This change can also be applied through the Wi-Fi modem user interface:
1. Log in at: 192.168.0.1 from the web browser of any device.
2. Log in using the following information:
- Username: cusadmin
- Password: xxxxxxxx (Password you chose during initial setup)
3. Go to the next section to apply changes:
Wireless ->Advanced -> 2.4 Ghz or 5Ghz -> Band Steering (Disable)
You'll need your Wi-Fi network password. If you can't remember it, you'll need to recover it.
Consider adjusting your Fizz Home Internet plan to better meet your needs
Reduced speeds are possible if your plan is not sufficient for your needs, or if several people are using your Wi-Fi network simultaneously.
Some devices connected to your Wi-Fi network could also be using your network in the background, for example:
- Operating system updates
- Photo albums that are syncing
- Cloud hosting
Here are some examples of average usage:
Type of service Bandwith Data Consumption YouTube
- UHD 4K: 6 to 10 Mbps
- 1080p: 4.5 Mbps
- 720p: 2.5 Mbps
- 480p: 2 Mbps

(Other than YouTube)
- High video quality: 5 Mbps
- Medium video quality: 2.5 Mbps
- Low video quality: 256 Kbps
- High video quality: 2 GB/hour
- Medium video quality: 1 GB/hour

- 3 people: 2 Mbps: 900 MB/hour
The information provided above is when the Wi-Fi connection is optimal, without interference or congestion.
Restore your Wi-Fi modem to its factory settings
IMPORTANT: This will reset any changes that have been made to your Wi-Fi modem settings to date. You may also need to reconfigure your devices’ Wi-Fi settings (network name, password, etc.).
Locate the reset button at the back of the Wi-Fi modem and using a small, sharp object, press the modem’s reset button for 10 seconds.
Once your modem has restarted, follow the same instructions you used when you initially installed it.
Reminder: The default username (Default Wi-Fi network) and password (Default key) for your Wi-Fi network are written on a sticker on the back of your Wi-Fi modem.
