I have purchased a Philips Hue Bridge (https://www.philips.co.nz/c-p/8718696555057/hue-bridge) and I am having trouble connecting it to my Vodafone (Huawei) HG659 modem. The Hue connects via an Ethernet cable into the modem. But the modem is not picking up the Hue despite it being physically connected. I have swapped out the cable and reset both products. I haven’t changed any of the settings when the modem was installed (it’s on fibre). It’s not obvious there are any obvious filters.
