Troubleshooting WiFi :
- Power cycle modem and router - Leave unplugged for 30 seconds.
- Power cycle computer/mobile device - Sometimes the issue is with the device itself, not the network.
- Raise WiFi router away from walls and clutter, which will have a significant impact on your signal strength. https://www.telus.com/en/bc/support/article/optimize-your-wifi
- Reposition WiFi receiver/dongle - Some adapters come with an external antenna or USB dock. A USB extension cable and tape also works.
- Use a WiFi analyzing app to determine where your signal is strongest and weakest. Check for overlapping channels.

What is a good signal? (https://www.screenbeam.com/wifihelp/wifibooster/wi-fi-signal-strength-what-is-a-good-signal/)
A perfect signal is -30 dBm. Likely, you do not have a perfect signal, but that is OK. Any signal between -67 to -30 dBm will let you perform most online activities.
Here is what the scale looks like and what each signal strength measurement means:
-30 dBm: This is the maximum signal strength. If you have this measurement, you are likely standing right next to the access point.
-50 dBm: This is considered an excellent signal strength.
-60 dBm: This is a good signal strength.
-67 dBm: This is a reliable signal strength. This is the minimum for any online services that require a reliable connection and Wi-Fi signal strength.
-70 dBm: This is not a strong signal strength. You may be able to check your email.
-80 dBm: This is an unreliable signal strength. You may be able to connect to your network, but you will not support most online activity.
-90 dBm: This is a bad signal strength. You are not likely to connect to internet at this level.
Ideally, you are looking to fall in the -60 dBm to -50 dBm range (since -30 dBm is unlikely). A signal strength at -67 dBm will work for a while, but this is the minimum strength you will want before your connection starts to suffer.
