I know variations of this have been asked before, but I still cannot get this working.

I have:

Basic Setup - DHCP Authentication - Auto

Switch Config - Port W checked against VLAN 10 and tagged box check at bottom.

Networking Port Setup : WAN Port Assignment set to VLAN10

But still no internet connectivity.

Can anyone tell me what I'm missing?

I haven't used DDWRT for a very long time so I'm not sure what you might have missed, but in case you haven't seen it our settings are listed here - https://help.vodafone.co.nz/app/answers/detail/a_id/5239. Hopefully something on that page jumps out for you!

(Not supported hardware yada yada I'm sure you don't need me to say this 😂)

Thanks for the reply.

Can you tell me what IS supported hardware for this, that I can currently buy urgently?

I'm not 100% sure which VF-supplied routers we still support but we currently supply the Ultra Hub (across xDSL, Fibre, and HFC) with a Technicolor T4400 Cable Modem for HFC/FibreX connections.

Do you have the T4400? Or one of our older cable modems?

Don't have either the UltraHub or the Technicolor modem. Have a Cisco DPC3008 modem and a Linksys WRT54G router/AP, which no longer wants to connect.

Stopped working properly after a well-meaning relative purchased a Gen 2 Vodafone TV box to replace the old T-box, and then the cable plan was changed from the old combined cable plan to some other HFC option.

Triying to get an Ultrahub urgently from VF Hornby in the hope that this will work OK with the Cisco and the Gen 2 box.

In terms of supported hardware only hardware VF supply is supported.

In terms of what will work the answer is anything that supports VLAN10 tagging on the WAN. That is probably 95% of routers available in the market now.

Well, that would be nice, if I could figure out if the TP-Link 3600 was one of the 95%, and if I could even remotely figure out how to set up VLAN tagging on such a beast running DD-WRT!

Did you get a new modem when you changed plan? That hardware sounds like the old HFC setup. If you haven't already, I'd suggest a call/chat with support.

You mean did the VF CSR on and of the four or five calls the elderly relative made at monthly intervals to drop the Vodafone TV component from her plan say "Hey, since you're now using the Gen 2 box and you are on cable, you'll probably need a new modem and perhaps hub" … No, I don't think that happened.

I meant 95% of new routers, not 95% of routers in general.

On such an old low end product I would not expect to find VLAN tagging support, and historically DD-WRT has been a buggy option for VLAN support on some hardware that it's tried to add the feature do.

You have a Cisco modem which means you have an old HFC connection, with a static IP.

An Ultra Hub likely won't work with the Cisco out of the box and the settings seem locked down so you likely can't reconfigure it.

You need to find out what your Static IP is (Maybe your old router has that saved if you can get back into it?) Otherwise the Vodafone technical dept, there is a Christchurch crew which are quite familiar I think if you can get to them. Emphasise that this is an old cable connection not a new one.

Once you know it, Choose Static IP as your Internet Connection/WAN Type in DD-WRT (or any other router)

Then:

IP: your ip (example 123.456.789.101)

Subnet mask: 255.255.255.0

Gateway: Your IP but change the last section/octet to 1. (example 123.456.789.1)

DNS1: 203.97.78.43

DNS2: 203.97.78.44

No VLAN Tagging

I don't see why Gen2 TV wouldn't work on this connection once it's going, but do consider upgrading to the newer HFC service, it's likely cheaper, and since you already have a standalone Gen2 box you can get the "Smart Connect" option (a tad cheaper since it doesn't include a TV) That's unless you get real fibre instead.

If you do get a new connection it will include a new Technicolor modem to replace the Cisco and a new Ultra Hub.

Thanks. That is a useful insight, which will short-circuit a dead-end diversion down the Ultrahub route.

You're dead right of course, that the existing connection would have been Static IP (I was thinking it might have been PPoE) and was preserved in the old Linksys WRT54G which had been running this quite happily until recently. Unfortunately the admin password for that was similarly preserved and hidden and I had to reset it to get access, which of course has now erased the Static IP. So your suggestion of getting hold of local support and getting the static IP details sounds like a winner.

PS: Actually I almost suspect that the connection has been upgraded to the new, faster HFC connection at VF's end, but not at the customer's end! Might explain why the Gen 2 performance was actually unreliable (connection rather than speed) and the local internet/Wifi speed has almost come to a halt.

Might get some joy on that tomorrow with support, especially knowing exactly what to focus on.

Okay, I found this post, they do say at some point connections were DHCP enabled (But maybe just newer ones?) So you could try DHCP with no VLAN and see what happens?

Ugh. Misery.

I've pretty much been trying nothing other than incantations involving dynamic DHCP. No dice.

Lol, I think the WRT54G would be the issue there (if using Wifi to the Vodafone TV)
