If your wirelessly-connected device(s) can’t connect to the internet but other devices can, this means your device(s) may be experiencing issues. Try each troubleshooting step to see if your device is able to reconnect to the internet:
Move the device closer to the modem to improve the Wi-Fi signal
Reboot the device. Sometimes, simple software issues can cause trouble connecting to the internet
If you still can’t connect to the internet, TELUS recommends seeking support from the device’s hardware manufacturer.
