The Vigor 166 is a pre-configured G.fast (Ultrafast Fibre) & VDSL2 (Superfast Fibre) modem that takes a G.fast or VDSL2 connection and performs PPPoE pass-through to the LAN / Ethernet port, which can then be used by a device such as a router to connect directly to the internet. It is the second function that is not handled properly via the setup functions available. I have submitted bug reports to DrayTek about 5 month ago, but have not seen a reaction to table the issues besides a message from the first line support person that the issues have been passed on to engineering. If you need an all-in-one solution; a broadband router with an integrated VDSL modem, or ADSL modem, all of the router models listed here include VDSL/ADSL modems. For G.fast, look for modems and routers that include G.fast capability, like the Vigor 2766ac.

After the reboot, Vigor 166 should come with some additional features such as basic LAN, Routing, NAT, and Firewall functionality. If you need a more advanced set of features, consider upgrading to Vigor 276x series or one of our load-balancer such as the Vigor 286x series. The Vigor 166 modem is designed exclusively for use in the UK, with the required network settings pre-set, such as the Openreach VLAN tag. Ideal Partner device for DrayTek dual-WAN products or any other vendor’s Ethernet WAN firewall. Reports DSL Line Status on DrayTek Vigor routers. Two operation modes for the Vigor 166 allow it to operate as a fully bridged DSL to Ethernet Modem, or as a mini Router with NAT DMZ Host. DrayTek offer a large range of G.fast, VDSL and ADSL modem equipped router models, as well as the dedicated Vigor 130 and Vigor 166 modems.

Something that caught my eye is there seems to be 2 G.Fast options, since i don't know what's what I've left as default... The Vigor 166 modem is pre-set to work as a fully-bridging modem. It can also be used as a mini router, providing NAT, port forwarding and DMZ Host to connected devices. The box includes a drilling template should you wish to mount the unit to something; although judicious use of velcro usually suits me fine:

ITU G.992.1 (G.DMT), ITU G.992.2 (G.Lite), ITU G.997.1, ITU G.992.5, ITU G.993.1, ITU G.993.2, ITU G.992.3Up to 330mbps and 50mbps upload with G.fast technology. Can be used with all the latest DSL standards, with Vectoring and 35b SuperVectoring. When in NAT Router mode, the Vigor 166’s two LAN ports can be used to connect two devices such as PCs, Wireless Access Points and Servers, or more with an additional switch.
