Problem connecting devices to Telus modem

[wireless]

I have a Honeywell thermostat which connects to the internet via a redlink internet gateway. I have issues connecting the redlink to the internet (via cable) and I was told it is a common issue with the white Telus modem. Does anyone have similar issues with connecting home devices to Telus modem?
