Anyone Using an Asus DSL-AC68U

Hi all! I just wanted to say what a fantastic resource this thread has been for me! I'm looking to replace my Openreach modem (HG612) and Homehub with a combo modem/router, but I knew very little about modems. I was considering the DSL-AC68U and some negative reviews lead me here - it's been like a crash-course!

After lurking for a while, and reading the debates about wether ASUS will fix this issue, I thought it worth mentioning (no one seems to have pointed this out yet) that in my search for a modem/router, I found that a number of ASUS units are reported as having VDSL sync issues and generally poor firmware - the DSL-N66U & DSL-N55U especially, and those models have both been out for a lot longer than this one.

The fact that this seems like a pattern with ASUS modem/routers is making me very wary of getting one, but I'd still like an all-in-one solution. Could anyone recommend any alternatives with good WiFi range and a stable integrated modem?

(I was also considering the Billion BiPAC 7800DXL, but a number of reviews mention poor WiFi performance)

Their routers are stable in my experience, work excellently here. The modem however is hit and miss.

I have to agree with chriscatt, ASUS have had plenty of time to even send out an official fix for the spectrum process but for some reason haven't mentioned or bothered with doing so. I'm beginning to lose faith in ASUS. I've successfully bid on a Fritz!Box 7490 yesterday on the famous auction website for around £160 (normally retail for £200 to £250+ as new). Hoping it'll arrive Monday. This has a Lantiq chipset which should pair well with the ECI DSLAM here.
 
The fact that people would even contemplate having to take somebody else's code to fix it in a commercial device speaks volumes of the current situation.

The patience of people on this forum has been comparable to that of the biblical Job. The amount of time and effort spent trying to diagnose and spot patterns of behaviour has been above and beyond. Pretty much everyone wants this device to deliver what was originally billed and should not have to accept excuses about this being difficult. I personally don't care whether it is a question of software or hardware: I do know that the HH5 is consistently outperforms the Asus device and is way more stable. I have no axe to grind with that observation: it is fact. Couple that with an Asus email telling me that:
"I saw that you find it unacceptable that the ASUS router performs on 49Mbps, while your BTHub reaches speeds of 64Mbps. Please be advised that this is normal and the speeds depend on multiple factors."

Seriously, the Asus should perform 25% slower than the HH5? I don't recall seeing that on any of the advertising.

I joined this thread when it was still on page 3 - here we are on page 41 with no real end in sight.
 
Yes some have had issues, as with any modem, however you cannot the ignore the fact that nine times out of ten the number of users of this cheap, and nasty 'thowaway' modem are finding it more stable in the majority, and doesn't require the excellent combined knowledge of people like yourself finding 'tweaks' to make it more line stable out of the box either. There are no excuses for asus's inability to produce a fix and given the size of the company, compared to sagem, it is blatantly obvious that they don't seem to care. Where are they here, do you seen any posts from a UK representative in any forum in the uk assuring us that they are aware there are issues and that they are working on them. Not even in any replies to my service query emails are they suggesting anything other than the standard tweaks. It is pathetic really...

Oh no do not get me wrong i agree it should be more stable, the software is poor, they could indeed do more to help but personally i think they should be doing that on their own forums rather than this E-Retailer forum.

Are you a ADSL or FTTC/VDSL user? That Billion is for ADSL only if you are VDSL and want a Billion the current range with VDSL modems is the 8200 and 8800.

Their routers are stable in my experience, work excellently here. The modem however is hit and miss.

Did you not consider a TP-Link W9980? Less than half the price also with a Lantiq chipset. Only has 600Mbps wifi though if that is important to you. Personally i hate wifi on every single device ive used, i just find it a laggy PITA lol

Could try watchdog.

I doubt they would care as i doubt the issue affects many plus its not a UK company.

I did consider that, but I recall reading some discussion about connection statistics/information being somewhat limited (even via the CLI). The other problem is that I don't see any mention of G.INP or G.vector support in the specification.
 
Hi, can anyone help with my settings for my ASUS DSL-AC68U

Ive just had BT Openreach out to fix a fault on my line because I was getting no DSL into the house - apparently there was some faulty hardware at the cabinet. (btw - on Sky Fibre, 38mbps)

Anyway, I've taken this opportunity to upgrade my AC68U to the latest firmware (2160) & put in the spectrum kill command using putty. However, I getting an absolute shed load of CRC error (50+ a minute when not browsing, 10000+ when streaming) & my line seems very unstable - its dropping out all the time - DL rate started out at 39999kbps now down to 37800kbps.

My question is this, do I need to kill the spectrum everytime the line DSL drops?
Have I applied the spectrum kill correctly using Putty? It didn't give any conformation that it worked.

Do I need to alter the router to settings recommended by Asus? They sent an email say to adjust the settings to the followings:
Stability adjustment =10db
Rx AGC Gain = Stable
TX Power = -3db
But I've seen a lot of people run it at defaults. Is there any benefit altering the Stability adjustment & the TX Power?

Here's my current settings & profile:

Are your CRCs constant or do they come in bursts? Whilst you say 50+ per minute that seems very high - my line which I suspect has some noise or lacking power (always been bad for voice calls being quiet) will be fairly constant in terms of regular CRC but will have spikes. The DSL-AC68U seems to exacerbate those spikes compared to a HG612.

With you being on Sky's 40/10 with the attainable rate you have just shows how unstable this device is. If it were a BT approved device, it would probably negotiate a higher SNR given the service you have so that may be why ASUS are suggesting a higher SNR - but it should be done automatically by the modem.

The stats thing i think was solved via a tool by a kitz user, no idea about if the device supports G.INP etc

LEAVE IT ALONE AND PLUG BACK IN THE SUPPLIED SKY GEAR OR THE OPENREACH MODEM.

If you have had an engineer out he has likely reset your line, over the next week or so DLM will configure it to what it classifys as stable, while it is doing this i recommend you stop using the Asus modem as DLMs interaction with it, does not seem to be 100% reliable. Let DLM do its thing first with your old/original gear then switch over. At the moment im not shocked any error figures will be showing as high if he reset the line, that would be normal (well normal within reason).

I almost ordered one of these a few months ago for the office. Let us know how it performs.

Will do. Unfortunately I'm not sure if it'll arrive tomorrow. Tracking still says 'Arrived at POL' on Saturday just after 10am. I'd have hoped it would've progressed through their network over the weekend and be at my local depot tomorrow morning, as it's Royal Mail Signed For 1st Class. Maybe the tracking is lagging, or this specific service no longer gives any more tracking details other than when it's accepted at the source Post Office, when it's out for delivery, and when it's signed by me.

EDIT: I believe it no longer has detailed tracking (Signed For), only will say if it's been posted and if and when it's been delivered, where Special Delivery Guaranteed also has detailed tracking, by the looks of it anyway.

Fair enough.

Do you know if there a way to have Openreach modem and AC68U connected together without the need for the Sky Hub?
I'll like to keep using the Asus router but use the Openreach modem to connect to the internet. I know I can connect the Asus router to the Sky Hub, but thats far too many devices for my liking & I dont have enough plugs!!

Well, good news is the Fritz!Box 7490 has arrived, bad news is that my neighbor's internet and phone service are out of action this morning so she's asked if she can connect to my wireless access point. This means I will potentially be held up with setting up and testing this :(.

Not that I know of, however what you could do is use the Sky router and just forward all traffic to Asus via DMZ settings.

Stand to be corrected but I think it is possible to leave out the Sky Hub completely and use the Asus router abd Sky/OR modem. You need to extract the connection credentials from the Sky Hub and then input these on the Asus.

These are not the credentials you use to access your Sky Account or the Sky Hub Admin page, rather a long string of data (linked to the MAC number of the Sky Hub and a password. Getting these details is possible but not simple.

If you google "Sky Hub Password Wireshark" you should find tutorials that will help you do it. Not tried myself but I have read that is usually successful - I assume it renders the Sky Hub useless as its credentials will be in use eleswhere (but not 100% on that).

Safer to just stick with the Sky router and stay within Skys T&C's than risk them cutting your service. There have been reports of users being cut off for not using the provided equipment.

"If you wish to use a modem or any other equipment that we have not supplied to you in order to access ADSL Sky Broadband we cannot guarantee that Sky Broadband will work with these. You must not use a modem or any other equipment that we have not supplied to you in order to access Sky Fibre Broadband."

Yeah you are right it is safer, but pointing out that it is possible. I'd be surprised if Sky cut anyone off, a bit like they don't try too hard to chase stand alone subscriptions for sky boxes being used in Spain etc (apart from multi-room boxes). Anyone losing sky internet would probably cancel the TV, which is their earner.

Not disagreeing with you, and I'm a Sky customer (not internet). If I took Sky internet I'd be very tempted to get a more flexible router installed. I think earlier in this thread some posters are doing just that?
 
Yeah, I've got my Sky Hub login credentials using Wireshark shark. But i thought I could only use this if the router had specialised firmware like Merlin or WRT?
 
Phone lines have a small amount of voltage which runs along them, the amount varies depending on line. Some modems in their stats will report the voltage on the line (as an example when i was ADSL with a Netgear DG834GT with DGTeam firmware that did). The higher the voltage generally the more stable a line is. Not always the case, you can have too much but thats easy for an engineer to fix. A neighbour in my street (3 doors away) on ADSL could get almost 3Mb more than i ever could even trying various routers and it was all down to their line having something stupid like half a volt more power.



You did not upset me, i assure you its a software issue with the device the hardware has been tested independently to make sure it works. The software is based on opensource code, which do you think is more likely to need fixing, hardware which has undergone independent tests before it can be produced and sold, or opensource software which has been modified even further by Asus for the device?

Its not just the modem chip which would had been tested either, every component in that device would have to go for testing before it can be sold. The power supply, the wifi, everything right down to the screws have to be certified. The plastic case is even likely to have undergone test involving setting it on fire to make sure the plastic is not too oily and encourages it to burst into flames/flammibility. This is not some knockoff fleabay chinese shed made stuff its a mass commercial product.

It would have even had to be tested in its final design, Mediatek would highly unlikely allow them a license to use their chips in a chipset which did not meet their approval either.

Hardware nowadays for a worldwide market is subject to more testing than you can imagine.

The very fact the device becomes more stable for many just by disabling the spectrum monitor/stats pages in the SOFTWARE, even shows that there are software issues with the device. To blame the hardware with no evidence is a bit silly. The fact with some software releases its made the device either more or less stable for some people also points back to SOFTWARE.



Which does not show anything, there have been users with problems with skys router (see their independent forum) which have gone away with another device. Also although you can argue it may or may not be more stable than the Asus still does not explain why for some that switch to say a Openreach Huawei modem instead of the Sky 102 find the Huawei more stable. The chipset is basically the same in both devices, one over the other should not perform significantly better. Yet they do.

Its no different (apart from how reliable you deem it to be) with the Asus situation. No doubt out there their is some other Mediatek device (probably bundled gear in the far east for some fibre service) and that gives no issues.

Im not defending Asus, the software is a bug ridden mess, FEC stats are obviously reported wrong, having to disable part of its software (IE spectrum) to make it more stable is daft and thats just issues we know about. The problem if any is Asus have gone for a chipset and then basically ported the software from another device of a differing chipset (IE the non DSL AC68u) and just encoded the modem driver in with that software..... It should had been tested more before they released it.

It could be so bad that it would be easier to start from scratch, without all the code at present i could not say, either way within a week or so i will hopefully know when i get one of them and dump all the software via TTL. From there ill probably laugh, rip a load of redundant cack out and fix it. Though no doubt then people will want certain things which make it buggy put back in.... Sometimes as a software dev you cant win or ever please people, more features in software ALWAYS EQUALS more problems.

The problem is, that it's not actually possible to test the hardware without the software...and while I agree that the standard safety testing stuff, EM/RFI compliance will have been done to death, any modem testing in the UK was clearly inadequate.

If the the whole ASUS modem router platform was compliance tested in the UK, there is clearly a problem with the compliance test. The stability of the modem on release was diabolical and although it has got better, the connection speed issues are still a problem. I would hope that if BT did the testing then it would reflect the real world conditions or the worst case conditions for a UK phone line....but this doesn't seem to be the case

Still, nobody except ASUS and Mediatek actually know if the problem is software or hardware. You may make an educated guess that it is software, but you cannot know. The reason I've taken issue with you stating that it is definitely software is simply that if it is the case, then it can be fixed. While we equally cannot know if this is a hardware issue, we have to entertain the notion that ASUS may not ever be able to provide a fix.

What they should have done is issue a UK only firmware version and work from that point forward with settings applicable to the UK only. Things like USPBO, Bitswap etc should not be configurable when they are a requirement.

Then they can start adding the extras as and when the UK VDSL spec changes such as G.INP and Vectoring with a good base firmware to work from.

Whilst mine is now stable, having to kill processes to maintain a steady connection makes Asus look unprofessional, lethargic at responding and somewhat carefree.
