Hi has anyone got step by step insructions on how to set up second modem as a wifi extender, the main modem is the vodafone one (black) the second one is the older vodafone one(white) Thanks
First of all you need at least 2 ethernet cables,
Second plug in an ethernet cable into the main modem,
then pug the ethernet cable into LAN1.
Turn the second modem on and there you go!
(this is working at my home with the ultra hub and the HG659)
Hope that helped you
