   Imagine how grateful some future reader with a similar problem will
be when she finds that precise, detailed description of how you solved
_your_ problem.

Probably about as grateful as I was that the help offered to me amounted to read the manual.

But hey, you're right - it's not the fault of some poor random individual who just wants to get rid of their Fritz!Box. So with that in mind, here we go...

Step 1) Plug in and setup modem. DM200 includes preconfigured setup for Zen Internet, although if you're worried about DLM being its usual jerky self, just bypass the config and set it up manually. This negates needing to reboot it. All the details needed to configure the modem are available in the Zen Customer Portal - you need to view the Detailed views under 'Your Services'. Your Username and Password are available there, and will also be in your welcome email.

Step 1a) When it asks for VLAN ID, put '101'.

Step 2) I cannot remember the name of the menu, but it's something like 'State' - hunt around, you can't break anything. Check 'Passthrough VLAN' before putting modem in Modem Only mode.

Step 2a) Forget ever seeing the Modem config screen ever again, since the IP address doesn't seem to work.

Step 3) Plug in Nighthawk. Connect it up using the fancy shielded ethernet cable provided. Ignore Netgear Genie, because it's useless and set up the connection manually by going into Internet and entering all your login details and the static IP Zen gives you. You don't need to set DNS, unless you want to use CloudFlare, Google or what have you.

Step 4) Head over to Advanced, click Advanced Setup and then VLAN/IPTV. Edit VLAN value to '101'. Make sure you enable VLAN again after editing the value because for some reason, it changes the value to disabled again once you've edited it. Not sure why such a vital setting to get online would be listed under Advanced rather than basic, but here we are.

You should then have Internet access. Huzzah!

Added QoL steps:

Step 5) Do the Firmware update before you do anything else, otherwise the router will start rebooting every time you try and download a file. I have no idea why it was doing that, but the FW update seems to have fixed this bout of tomfoolery.

Step 6) Assign wired devices a reserved IP address by going into Advanced -> Setup (NOT Setup Wizard) -> LAN and configuring it there. Failure to do so will mean anytime the router does reboot, the IP address will change and if you're running a media server or something like that, you're going to have a bad time if the IP keeps changing.

I think that about covers it all for Zen Internet at least. Can't say whether this would work with all over UK ISPs.
