BT g.fast with dsl88u

[andy9054]

Hi

I’ve scoured the net and read various forums to get g.fast working with this but I dont seem to be getting anywhere. When i got it out of the box with build 502 firmware it managed to get a DSL connection (said in GUI it was connected and solid dsl light)

I just upgraded the firmware as I wanted to get bridge mode working (didnt really know how to either) to firmware v1.10.06 build591 but now it wont get a DSL connection, i tried rolling back to 502 and doesnt work either!

I’ve tried some recommended approaches of choosing uk/plusnet/vdsl + iptv as the provider in the quick wizard setup and then manually change dsl settings to g.fast/annex a in administration but still no joy

Would anyone be able to help please?

thx

The DSl-AC88U for bridge mode does not support VLAN ID’s (802.1q) so you will need to ensure if you use bridge mode, then the Router can handle this aspect (not DSL-AC88U).

(expensive modem) ;-)

At some point last year, ASUS removed G.fast from the Auto synch options under DSL Settings from the firmware, so you will need to specify G.fast option manually

For me it doesnt make any sense to use this expensive DSL-modemrouter in bridge mode as modem only without any routing functionality.

Get a cheap approved provider modem instead with full DSL-support.

The reason to use this Asus DSL-router is only to have a single router-device without need for extra modem.

Thanks for the replies….haha yeah I get the jabs for it being the worlds most expensive modem, however, only 2 modems that exist that support g.fast from what I can see, a Huawei MT992 and a Zyxel , £300 on ebay for the Huawei and zyxel only on Alibaba but i couldnt find any sellers.

I couldnt get the Huawei MT992 from BT either (they used to ship with early g.fast), so that left this, yeah its expensive to be just a modem. I used to have normal non g.fast with google wifi which worked great to give ethernet downstairs and mesh wifi through the house. If the ac88u gives as good wifi coverage that would be great but I do need the ethernet downstairs, I’ve not had great luck with powerline adapters and I already have the google wifi.

So, here I am…sorry for the length post but hopefully it shows all the info. I’ll take just trying to get it hold a DSL connection for now without the bridge only, but help with both would be great 😊

attached pics of the setup…

No problem, I know of a couple of other forum members that have chosen this way for g.fast

What are you connecting the DSL-AC88U to? (router) and what did BT give you as part of you G.fast connecting device setup ?

Which is preferred option, trying to see of DSL-AC88U has suitable wifi strength or using it as modem only, we can then advise accordingly ?

Modem only would be ideal as i do like the google wifi.

So, I have a google puk plugged into it at the moment (LAN2) (google wifi acts as arouter too, and thats what i had before on non-g.fast with the draytek 130 modem)

BT just gave me the smart hub 2 and then 3 discs (which are awful compared to g wifi)

As I said though, at the moment, the 88u cant even get the DSL connection (a solid light or say its connected in the UI)

I think your current setup (idea) will not work, the Google puk if plugged into DSL-AC88U (bridge) will need to support vlan ID configuration to 101.

With your previous draytek 130 modem this managed the vlan option, but the DSL-AC88U will not if it is set to bridge mode?

only option really is to use DSL-AC88U as modem and a router and see if google puk can b plugged into ethernet port to accept connection and then disable DSL-AC88U wifi

Alas I do not know much about Google puks ;-)

Note: I realise on one of your screen captures, you have set Bridge for VLAN 102, (should be 101) but this is a know bug with the DSL-AC88U that VLAN ID in Bridge do not work.

 

Hope tat helps ?

hmm, I think you’re right, you could use the google wifi as some sort of bridge for the ethernet but wouldnt mesh.

I think its back to the old setup unless you any ideas on a g.fast modem?

thanks for the advice!

I could give you my AVM Fritz!Box 7582 with G.fast for 150€ ;-)

ADSL and vplus doesnt work on it but G.fast perfect and everything else too, tested at work.

It had the problem that the switching relay between ADSL and G.fast didnt switch due to defective driver transistor, so the much higher levels for G.fast destroyed the input of ADSL chip, the other chip for G.fast only running perfectly fine.

And I wont get G.fast as we’ve been upgraded to vplus last year, so no use anymore and sell it.

Whats with 7583 new for 300GBP, it should support G.fast too, or are there problems in UK with it?

I have normal faster fibre with TalkTalk and this is exactly how I have set up my 3 google wifi mesh units.  The wifi on the AC88U is turned off.

@Grisu – behave  ;-)

@andy9054 – I assume BT Smart Hub 2 does not support Bridge (pppoe Pashhrough) I had a look online and could not clarify.

Fritz!Box 7582 or 7583 would be perfect, but not available suitable for UK (International Version) is what you would need so It would have English language option

There is the Zisa G100 modem, which is same chipset as DSL-AC88U, but these are hard to find online

Or the Huawei MT992 Openreach modem of Ebay for £150-200 if you are lucky.

or Draytek 166 – but have not seen these yet ? DrayTek Vigor 166

(If you give me a day, I will check with ASUS to see if the new Firmware they are releasing hopefully next month will support Bridge Mode with VLAN ID’s)

thanks

smart hub 2 , I cant for the life of me get going in bridge mode, albeit some claim to have got it working , its definitely not supported fully, the closest i saw was this ; https://community.bt.com/t5/Home-setup-Wi-Fi-network/Smart-Hub-2-as-a-Modem/td-p/1922978

yeah i found the same as you, the Huawei MT992 i found a few on ebay but closer to £250-300 and i know i paid a bit for the asus but (!), the Zyxel and Zisa are both alibaba jobs and dont really seem to be in stock one you dive into it unless you want to buy 500 of em.

Draytek 166 from all i read was meant to be released q4 this year but not heard anything about it

 

thanks!

Has been only a fast and last offer if someone likes to test it in UK, I have a buyer here who will use it as mesh-node end of week.

7582 (20002809) and 7583 (20002847) are internat. versions with english and so on.

I found 7583 listed on geizhals.eu and thought they are public available, seems to be not true after more search.

But still on ebay and more on other second hand platforms like willhaben.at.

 

Would be funny to see one running in UK how it behaves, I am too curious thats all! :-)

 

BTW: Isnt there always a modem included from provider, cant imagine that they sell a contract without?!?

It appears impossible to buy a G.Fast modem at present.

I’ve tried all sorts of suppliers on Alibaba, AliExpress, GearBest, DHGate etc. many of whom claim to sell the Huawei MT992 or the Zyxel/Zisa equivalents. None of them, not a single one has ever been able to supply. Nor are they able to answer why they are offering/advertising something for sale if it’s unavailable. Minimum order quantities have never been the issue, the existence of the product has.

Draytek’s estimate of Q2/Q3 for the 166 looks wildly optimistic, I don’t think anyone has seen one in the wild yet.

I really hope some sensible options emerge soon. I don’t like Draytek kit, never have, never will so hope there is at least one alternative to the 166.

I to a few months ago went down the Alibaba / Alibaba Express route, all ended in no stock for various G.fast products.

Even tried to encourage ASUS to manufacture a modem only device suitable for G.fast. they where not interested as no market value.

I am staying with VDSL until 5G hits my area and then if prices and flexibility are palatable, purchase an unlimited 5G sim and job done

‘such fun’
