Why I have trouble accessing Telus internet wifi with android smartphones? While iPhone, iPad are perfectly OK.?
I've never had a problem with the Android phones I have used on Telus Wi-Fi. What devices and what issues are you seeing?
How old are those Android phones and how are you setting up your WiFi? The older the device, the less compatible it will be with 5GHz and WPA2 settings. Older devices might also not support AC and this can extend to value devices as well.
