Can anyone please advise, I thought this modem was compatible with my fibre to the cabinet line. but i keep getting "The DNS server isnt responding" The modem will not let me access its menue so I am a bit stuck???
So what are connecting to the modem - which router?
And is BT your ISP?
Yes it is BT Infinity "to the cabinet". Unfortunately the modem will not let me access its settings which is hopeless. I suspect the box it actually not suitable for BT Infinity to the cabinet. As it appears this is line is VDSL2 is that correct and this box just says VDSL??? Obviously I have tried every possible option, manual DNS and IP4 settings you name it!!! including the sellers recomendations but whilst I can get a ping respose I cannot get the Internet with any modified settings or automatically. Of course not being able to access the modem settings due to a fault with the modem is hopeless, so I am going to return it. Unfortunatley buying online is always a risk and a real pain when it goes wrong, as I assumed this box would allow me to connect to any of my other Linksys, D Link or Netgear routers and let me ditch the BT Hub which is preventing my VPN from working.
Many thanks for at least reading my posts.
The HG612 is entirely suitable for Infinity and should work without any settings being changed, it is what I use. It is entirely possible the device is faulty. However, unlocking the modem is a trivial excercise if you wish to try that before returning it. Instructions can be found here
The HG612 is just a modem, all the settings you will need to make will be in the router. Are you sure you have configured the Linksys correctly? I don't know where the menus are but these are the various settings you need.
Authentication either auto if available or CHAP if not.
