ASUS DSL-AC68U (VDSL modem/router)
« on: September 08, 2014, 01:32:42 AM »

ASUS has now entered the vDSL modem/router market with the ASUS DSL-AC68U

New for sale from today at broadband buyer.   The Price at 202.69 may be a bit too steep for some though :(

A couple of things people ought to consider if they are thinking of purchasing it.  For some  each listed item might be a deal breaker.

It has only has 1x USB port although it is a USB 3 as opposed to 2 x USB ports (USB 2 and USB 3) on the ASUS RT-AC68U.

At present ( 9th September 2014), there is no 3rd party firmware (tomato, DD-WRT, Asuswrt-merlin) available to flash it for more advanced features.

I noticed yesterday the fact that it only had one USB port and also that its lost the dedicated WAN port when compared to the RT-AC68U.

I suppose its biggest selling point by far will be the fact it works on both ADSL & VDSL by having an integrated DSL modem.   
There is little choice for UK consumers looking to purchase a VDSL modem/router and this is one of the very few that will fit the bill.

ETA

The rumour is that it contains a Lantiq chipset.

I missed that.  At this price point I think they have thrown away flexibility.  Perhaps they thought people who would be purchasing it did not care and were just run of mill punters who just want to plug and play without thinking about it.  Having said that BT Open Reach (Kelly communications) seem to be doing the installs for ISPs (in my area with talktalk they are) and they fit a separate VDSL Modem even if the router supplied (HG635) has its own integrated VDSL Modem.

No doubt one of the LAN ports will also be an uplink port, so just like the vast majority of other DSL routers, its no big deal. 
If youre buying for DSL then its not really a loss of switch ports as you'd still have 4 LAN.   Its not the router you'd buy anyhow if you had cable, but the flexibility is still there, just you'd only have 3 LAN.

From the photos its obvious that the dedicated WAN port has been removed to make way for the DSL port.   No idea why they removed the USB2 port though.

40 off is a good deal.  Even at 159.99 thats still quite a lot cheaper than broadband buyer.. which is highly unusual.

What also worries me is that broadband buyer is advertising it as VDSL2/ADSL2+ modem router, yet theres no mention of VDSL on PCWorld... nor even ADSL when it comes to that.. not even where they list the ports...  and its about the price youd expect to pay for the cheaper RT version.  Just double check when you pick it up that it is VDSL modem router and  not an RT-AC68U.

The ASUS site definitely specifies the DSL-AC68U as being a VDSL/ADSL modem router

Looking at the firmware for the DSL-AC68U, it really must have two CPUs. The firmware contains two squashfs filesystems, one containing a set of programs compiled for an ARM cpu, and the other filesystem, the one with the DSL driver, contains another set of programs compiled for a MIPS cpu.

The picture of the back of it on pcworld.co.uk does show the DSL port.

Thanks Kitz

I check on pcworld site as it does metion spec: Model    DSL-AC68U (that should be VDSL modem/router) I will check the model label tomorrow if it was RT, will not buy it. If it was DSL-AC68U then I buy it.

Updated:

I am now not buying it cos someone from overclockers say this VDSL cause DLM because of increasing CRC errors. http://forums.overclockers.co.uk/showpost.php?p=26933594&postcount=55

Thanks for bringing that to our attention.

I'm not impressed with this router - whether it's because I was testing and had swapped over between the OR modem and the DSL-AC68U a few times, or had a dodgy RJ11 that caused a load of CRC errors, but DLM kicked in an forced some interleaving on my line for couple of weeks back on the OR modem.

ECI cabinet - the DSL consistently syncs 3 - 4Mbps lower on downstream but upstream rate is higher by about 2 - 3Mbps compared to the ECI modem.

I may wait for another firmware update before trying the DSL-AC68U again - for the moment I'm back with the RT-AC68U and OR modem combination which is stable for me for weeks on end.

In all fairness he did say he wasnt sure if it was because he was testing.  We've seen members here who have fallen to the same DLM trap purely because of testing and swapping routers, so it would be interesting to see how that developed.

I must say though that I was surprised earlier when you mentioned you were buying this..  especially in view of your opinions on the DSL-N66U which contains a similar MediaTek chipset.
I have mentioned to you a few times that in view of your line being similar to mine (after it went live) that you may be best looking at one with a Broadcom chipset. 

You'll find that most of the regs on here like the stability & performance of the Broadcom chipsets and we believe chipset to be an important factor when it comes to DSL performance.   Its also why Ive specifically listed chipset information in the list here..  but I'll spell it out again..  try looking for a combined unit with a BCM chipset.  Youve already seen that the MediaTek & Lantiqs dont perform quite as well on your line.

It looks like the DSL-AC68U uses a Broadcom chip for its WiFi. That's in the ARM part.

If you can get telnet access to a shell, to the MIPS part, there are commands such as wan and adslphxcmd and its always worth looking under /proc/ for anything interesting. There are various references to tc3162 - tc presumably indicating TrendChip. The RaLink and TrendChip companies merged and the resulting company is now called MediaTek.

Im not a linux bod so perhaps others may be able to suggest some more commands, but the usual one to try first is

This was also posted on the plusnet forum, in summary we haven't yet figured out how to get to a shell inside the MIPS part with the DSL modem, but some of the DSL stuff has been stored under /tmp/adsl/ - I think most of it is available from the web interface anyway.
