Non BT gfast modemrouter

Richgj — Fri, 29 Jan 2021 18:45:11 GMT

Hi I have gfast bb and have purchased an Zyxel xmgg3927 router and for the life of me I can’t get it to connect to the internet. I have assumed the settings /user name would be the same as when I had FTTC but the router just doesn’t like the settings it also gets hung up on having a password after the user name.

It would be great if any one can confirm the settings or indeed if there is a better third party gfast router that is easier to set up as this one regularly tells me what I’m doing isn’t allowed or tells me it can’t complete the action ..

Many thanks Rich

Do you have a separate G.FAST modem?

Hi there no my understanding was that the ZYXEL was also a modem as well as a router similar to the smart hub. Rich

That would be my understanding.

Are you sure you are entering the correct PPPoE details of bthomehub@btbroadband.com and password BT? Also set VLAN id to 101

Yes to the user name and password I need to check the vlan but I’ll now need to wait until the kids go to bed as I’ve plugged in the smart hub again to keep them happy.

Draytek vigor 166.

I have used the 130 and Draytek put a lot of work into it to ensure it would work with BT, and I believe they have done the same with the 166 with specific BT firmware.

Might be worth a read up as my vigor 130 has worked flawlessly.

Thanks I ‘ll have another look I’ve used Draytek before and as you say they are very good. I must admit I thought it was just a modem which was why I had discounted it. Rich

Ah, yes.

It probably can do DHCP like the 130 can, but I think its probably better in bridge mode with a separate router.

which means you can have another shiny toy 🙂

From Draytek

"The Vigor 166 can be used either as a modem, bridging G.Fast or VDSl2 to its
Ethernet ports, or as a router, connecting directly to the Internet and providing
connectivity to any connected devices.
The Vigor 166 is pre-configured to work with most UK ISPs, with ideal settings for
connecting to the Openreach G.Fast / VDSL2 network, adding VLAN tag 101 to
any traffic passing through it."

It is not actually necessary to have a password as it is not required. Some third party router/modems require one though. Try it without a password.

Thanks to Amazon I’ve ordered one . It will be here on Sunday so I’ll hopefully update after that..

I tried a XMG3927 on my g.fast connection around 6 months ago and having used many other Zyxel routers beforehand I had no issues getting it connected. They do have their 'quirks' in the interface though I'll admit.
As far as the router interface is concerned it considers g.fast as vdsl, so configure it just like you'd configure a Zyxel for VDSL. See https://kitz.co.uk/routers/zyxel_VMG8324-B10A_vdsl_setup.htm for an example.

Unfortunately I sent it back as it seemed incompatible with BT's IPV6 implementation.

Use caution if you get a Vigor 166 as it seems to underperform on VDSL anyway, even triggering DLM due high error rates for many people. Haven't seen many use it with g.fast though so curious about that.

Thanks for the help. the Draytek doesn’t arrive until this evening so may struggle to get anything done tonight. I had another play yesterday with the Zyxel and thought I was there as it was showing as connected but I couldn’t bring any web pages up.

which prompts another question currently use Amazon eero as a mesh system for wifi and its great apart from with but hub I end up with a double nat situation which is giving me issues. My plan was to put the Zyxel into bridge mode ( I get that’s an expensive router to use) but i could then connect the eero and hopefully the issue would be sorted. Would i connect the eero to the lan port or would it need to be connected to the wan port which would then need to be configured.

im open to other suggestions. Many thanks Rich

My understanding is,

The WAN port is used to connect to devices that give a direct route to the internet using a point to point connection (such as point to point over ethernet) so you would normally have a 'modem' style device in bridge doing the G.Fast connection then connected to the WAN port a router which then connects using PPPoe to the ISP, the router then provides LAN ports & local IP addresses to the devices in your home. The Zyxel device in routing mode does all this internally.

With the Zyexel in bridge mode, you would then need something to provide the login via PPPoe which the eero can't do.
