Asus DSL AC 68U downstream interleaved

[Ian72]

Hi Guys,

Wondering if anyone can help me I recently bought the Asus Dsl Ac68U to use instead of the useless Bt Homehub.

It’s a busy household with lots of internet use including gaming which in particular didn’t work very well using the BtHomehub as the best bufferbloat rating it had was a c.

The Asus router has helped with this as it has qos but the problem is my download speed has dropped lower than I got on the hub and is set to interleaved.

I updated the firmware and did a factory reset as Asus say to do but nothing has changed,I’m really disappointed as I’d read great reviews about this modem/router and that people had got higher speeds using it than the Homehub.

Does anyone know how to get fastpath on the downstream please?

Did you buy the DSL-AC68U new? if so then to cut a very long story short, the unit needs to be returned and swapped for another unit which is more suitable.

Basically, BT a few years back started to punish users whom used the DSL-AC68u because it uses the MediaTek (ECONET) DSL chipset, this chipset unfortunately even though worked well on very short stable lines, was not good for long lines which had lots of interference.

This is part of the reason why ASUS then introduced the DSL-AC88U which has a Broadcom DSL chipset and supported G.inp

The DSLAM controls the level of interleaving and whether Fastpath is applied, you connect to a Broadcom DSLAM, (which is great) and you old BT hub was also Broadcom, so this is why synch speeds have dropped so much

BT introduced a couple of years ago G.INP which reduces SNR (downstream) and increases synch speed, alas your DSL-AC68U does not support BT G.INP, so again you are fighting a loosing battle

Hope this helps?

Thanks for the advice,can I get a modem that  has a broadcom chipset and use the 68u just as a router?

Or isn’t that as good?

If so can you suggest some decent modems?

If you are not using all four of the ethernet ports, then one can be used to connect to the modem as a sudo WAN port.

The Draytek 130 is an approved BT modem ( a tad expensive) or maybe you BT hub (which one do you have) maybe able to support bridge mode which is enable it to act as modem?

The Draytek 130 is an Lantiq DSL chipset, but support G.inp and works very well? (I have one)

I have 2 Bt hubs, the smart hub 1 and a smarthub 2 I’ve no idea if they can be used as a modem only

Would the Netgear dm200 be of to use the 68u? and solve the problem?

The Netgear DM200 is a cheap unit and has had issues with IPTV/stability etc,

Alas BT supports only modem/product that have gone thru an approval process (MCT) and if you use a product (modem) that is not supported and a fault occurs, they could charge you etc.

Alas your 2 x BT HB cannot be set-up as a modem (easily) so you are left with either DrayTek 130 or say the Fritz!Box 3490 (I love these) and they can be set-up as modem (Bridge) or used a modem and router are BT approved. (wifi is week) but if you game via Xbox / PS4 then has the option for port sharing which give you open NAT (NAT type 1) and time control for wifi access.

I noticed the Dm 200 on this approved list but if it has stability problems I won’t bother.

I’m annoyed I’ve got to get something else basically because of Bt,which is the reason I’ve gone down this router in  the first place.

Gaming is on pc the 68u qos has worked well stopping any latency issues we were getting with the Smarthub,it’s just the download speed being interleaved.

Netgear is usually poor from a firmware perspective and best avoided, but I am using the Netgear XR500 due to its Geo-Filter (british) add-on and love the gaming (console)

Alas no ASUS product are MCT approved hence maybe why the DSl-AC68U is causing line/DSL speed issues.

I believe (if you are technical) you could get hold of a BT HG612 modem and get it unlocked to support G.inp (this was a while ago but I a sure it still applies)

BT HG612 is Broadcom and take a look at link, just make sure the HG612 is v 3b

https://kitz.co.uk/routers/hg612unlock.htm give more details etc.

What is the better option for me the fritzbox 3490 or the Vigor 130 ? I’m looking at some on ebay barely used but I’m not sure which to go for

I went with Fritz!Box 7590, but for sure a cheaper 7490 or what UK_Sentinel recommended a 3490 will be fine too and you get it used for down to 50€. I am very happy with them and came from many different Asus routers too with nothing but troubles. They offer everything in their settings and nothing is really useful or reliable working. Incredible what you can set, but it wont work because of buggy firmware while hardware could do very well. Known bugs ar never solved and new are coming with each firmware update. One step forward and 2 back … thats their behavior in my for sure personal observation.

It is difficult, if your house is not to big and you game via wired, I would buy the Fritz!Box 3490 and see how that goes, you can always convert it to act as modem if you are not happy.

Fritz!box does not have the ability to limit what kids see online easily, unlike ASUS AiProtection, but for everything else, they are a dream. aBT does have its own content control or you can sign up for a free account for OPENDNS etc and set the DNS servers of the Fritz!Box to point in that direction

The Draytek 130 is a great modem, but DrayTek user interface is not easy to understand or update

Enjoy the choices and both @grisu and I are Fritz!Box fans, shame for me that they have not got a geo-filter enabled device  ;-)

Well I’d be using the device as a modem with the Asus router which works well when just used as a router I hope?

I wouldn’t be very popular if I said I’d just bought a much cheaper device than the one I’d just got that works better and would have to try and sell!

So would all these work as well as each other Fritzbox 3490,Vigor 130 the openreach  huawei hg612 3b unlocked.

The huawei is the cheapest but I won’t to make sure whatever I get now solves the issue.

I fit makes any difference I found out my cabinet is a huawei if that helps choose which modem.

Thanks again guys for all your help,as I said the Asus has worked well for gaming but the download speed has dropped and is getting worse

I would then purchase the DrayTeK 130 modem, it works as a modem and is approved by BT (I have one) this should meet with your needs and not require any other changes etc.

When it arrives, just plug it in and it should work straight out of the box,

Thanks guys,I’ve ordered the Draytek,how do I connect it to the Asus.

Do I go into the router first and disable the modem?

In which case how do I do that?

And then is it just a case of plugging in the draytek to it?

Sorry bit of a noob at this, always used the standard isp router modem until now
