Anyone Using an Asus DSL-AC68U

I'm not sure to be honest. I noticed most disconnects at night (say 9pm to 2am UK time) when nothing was being used, but also got them during streaming, light office use etc. I submitted several feedback requests to Asus (including the system log) and on that basis they said to make adjustments. After the third (maybe 4th) lot of recommendations with no improvement I gave up, and hooked it up to the OR modem (problems instantly gone). After a couple of weeks like that I decided to return it while I could. I also unlocked my OR modem (Huawei HG612) with a view to seeing if I could get any clues from that, but to be honest, I'm just relieved to have a stable service again. I really needed the LAN port that was being used with the OR modem, else I might have stick with it (used with OR modem) a bit longer.
 
Frustrating times getting settings correct

I've spent about four hours today trying to get some stability from the DSL-AC68U.

I had BT here a while ago and since their visit I have had ten days of uninterrupted operation with the HH5 connecting at 68MB/s down and 18MB/s up.

I put on my Asus today and I was thrilled to see I matched both download and upload speeds. Unfortunately, after a couple of hours the CRC count was accelerating (500 to 3000 within a few minutes) so I made some of the changes suggested by Asus a few weeks ago. Having rebooted the router, the connection speed was 49MB/s. I had a couple of more changes but couldn't get above the 49MB/s threshold. Worried that DLM may have kicked in and my speed may have been reduced because of line errors, I went back to the HH5. I'm back at 68MB/s.

The Asus is a cracking piece of gear but the lack of stability I have witnessed is very frustrating. This is all made much more difficult with the threat of DLM forcing line speeds down if you do want an extended period of testing.

It would be a big help if there was some form of guidance about what needs changing based on the stats in front of you.
 
I tried a Homehub 5 for a while, and found I had to reset it about every 2 weeks, where before my OR modem (with a Billion 7800N router) I honestly don't remember resetting. From my experience out of the box, VDSL stability (best to worst) is OR-Homehub5-Asus.

The whole DLM thing is confusing though, because like you as soon as I put my OR modem back I was instantly back to just about full speeds. My best possible speeds are 38/8 or thereabouts (according to BT diagnostics), and a few weeks with the Asus saw me down to about 30/5. If it was just DLM I wouldnt of thought I'd get back to normal so quick?

Also, with default settings, the DSL-AC68U started out at over 40 d/l, even though BT tests state that is beyond the max for my line.

This suggests to me that the DSL-AC68U is not detecting line conditions correctly in the way that my (3 years old) OR modem can, or even the more recent Homehub 5.

I'd recommend opening a support ticket with Asus, the more the merrier. It should just work - and it doesn't.
 
I tried mine again yesterday on the latest firmware. Everything was fine for a couple of hours and then suddenly its resetting every 5 minutes or so. This is with some of the tweaks like Bitswap disabled and reduced Tx Power.

I put the HH5 back in and its been stable ever since. With the dsl-ac68u working as just a router behind the HH I then tried to fill in the feedback form, but it wouldn't let me submit it as it thinks I dont have an internet connection.

I'll leave the HH connected for a couple more days so as to not annoy the DLM so much, then plug the asus back in and fill in the feedback info whilst its connected and being unstable.
 
I've now got mine set as follows and its been stable for almost 14 hrs now...

VDSL Modulation: VDSL2
Modulation: Annex A
Rx AGC Gain Adjustment: Stable
UPBO: Auto
Bitswap: Enabled
SRA: Disabled
Improved Noise Protection: Enabled

Everything else disabled.

No CRCs, so it's looking promising.
 
I have been on to my Rep at Asus today and I am trying to get the Technical department to look and read this thread to see what issues you are having with these Routers. I want to make sure you are happy with them. As soon as I know more i will let you know.
 
ASUS having a look would be good

Just been on a call with them and changed one setting based on advice. It was good for a few minutes and then CRCs galore. I don't like hit and miss, particularly as that DLM sword dangles above.

Exactly the same thing here. The new firmware, no matter what combination of settings I've tried, just eventually throws an enormous amount of CRC's and eventually loses sync. I'm fearing what DLM may have in store for me tomorrow. The firmware version ending 693 works, but I do still have some CRC's on the downstream unfortunately (no where near as bad as thousands within a few minutes or a few hours on the new firmware, so far 256 CRC errors downstream with nearly 3 hours of uptime, roughly occurs at a rate of 1-2 CRC every minute plus an occasional spike). Connected to an ECI cabinet, attainable 91/30 with UPBO enabled/auto, otherwise 91/39 with UPBO disabled. Prior to using the ASUS I've been using an ECI /r modem, which kept me on fastpath at 74/20. Tomorrow, due to all the re-syncs and errors over the recent 24 hours, DLM may decide to intervene and increase the INP and delay settings (interleaving).

I'm wondering if I should try 2048, 2049 and/or 2050. I've only tested 693 and 2072.
