Anyone Using an Asus DSL-AC68U

This sync is going well - 18 hours connection time, 9 downstream CRC and 0 upstream. I've never seen the numbers so low on this device for my line.

FECDown - 7474197, so less than the last sync which was 21million and counting in 10 hour period. Still not sure whether this is to be expected on an interleaved line.

I don't trust the FEC count on this device, as overriding to fastpath with the same sync rate didn't give me thousands or millions of CRC errors for a similar uptime. I would say either it's normal behaviour or it's mis-counting.

P.S. I'm referring to the sync rate of 49Mbps, set on the DSLAM at the moment.

In which case you probably would be better off with a device with external antennae to help with range. The Billion devices (8800NL and AXL) both have internal antennae and I read a review of the AXL that the range wasn't as good as other routers out there, which isn't surprising with the antennae.

That is what I read also about the billion devices mentioned. I currently have the RT-N66U along with the standard fiber modem supplied with Zen. I'll stick to that until something becomes reliable enough to take the plunge.

Hi All,

Any of you on PlusNet having these sync/error issues?
Click to expand...

Yep, Im on plusnet. I was having quite severe issues with the original firmware - Not so many connection drops, but lots of CRCs that caused DLM to kick in.

The Beta Firmwares have got gradually better, and 2144 seems pretty good for me. Same downstream and 2mb better upstream than I've had with any other device, and not that many CRC errors - around 5 per hour.

However, It seems really hit and miss - Some other people have found they this new firmware doesn't help.
 
A bit off topic, but anyone who has been impacted by DLM when testing this router might find that if you were on interleaving and had a speed drop (like I currently am) before 21st November, the connection will likely stay that way as BT have been forced to turn off DLM.

On the plus side, as many FECs, CRCs, ES etc. as you like without impacting the connection. Probably.
 
Personally I think ASUS are being very coy about what why it's taking so long at fixing this device.

Although I don't own one now having returned it to PC World, it's now 2+ months since this was launched in the UK and it's still not fixed. It begs the question how was it tested and where for starters, secondly why after so many issues with their other DSL modems have they stuck with the same hardware supplier for modems?

I have over the years loved ASUS products but this one has left quite a sour after taste.

BT had initially asked for a stay of the injunction (paten 495) until 8th December 2014 in order “to enable it to make alterations to its systems to render them non-infringing“, but this would have required them to pay extra costs and so instead they appear to have simply disabled the system (BT already claims to have adopted an alternative approach, as per the original article above).

http://www.worldipreview.com/news/bt-shrugs-off-court-of-appeal-patent-ruling-7401

“Although BT is disappointed with [Tuesday’s] ruling, we have made minor changes to our programming which means these two decisions will have no material effect on the operation of our networks.”

BT hasn't spent millions of £s investing in equipment just to turn it off if it just needs a firmware upgrade. They have had a year to develop it since the first court ruling was in December 2013. So my guess is they will now be upgrading this equipment any time soon if they haven't already started doing so. My guess is if we all start seeing a random line reset in the coming days/weeks then DLM is slowly being turned back on.

I hope that isn't the case. The crappy ASUS modem has had me DLMed down to nearly half the speed of the BT OR modem.....I definitely do not want to stay at that rate :(

Hi,
Thanks for the reply, I've had the engineers back again today, I've been put back onto fastpath again but seen massive crc error spikes and then re-syncs. I wondered if anyone else was suffering on that ISP.

Interleaving is DSL-AC68U's worst nightmare, or is it ours? lol - That's interesting news, thanks for letting us know :)

Do isps allow fastpath with fiber? I wasn't even sure if it was possible with fiber in the first place! Do Zen allow it?

i would say yes, as i would have a much higher ping on interleaved.

The 2144 build has now disappeared from download, only 2139 is now available. New build incoming?
Click to expand...

I cant download it too. This shows that asus dont handle the things carefully. Also bad support(not responding to mails) make me not to buy asus device again. For every device, I have seen asus representatives in some forums. For dsl-ac68u, I cant see anyone. All are dissapeared.

I have 52 CRC's after 2 days and six hours with the 2144 which is still showing under my product support to download...

The BToR DLM measures the following parameters:

Total 24hr SES (downstream)
Total 24hr ES (downstream)
Total 24hr SES (upstream)
Total 24hr ES (upstream)
Total 24hr uptime
Total 24hr unforced retrain count
Total 24hr Full Initialisations
Total 24hr failed initialisations
Line rate (downstream) in previous 24hr period
Minimum line rate (downstream) in previous 24hr period
Maximum line rate (downstream) in previous 24hr period
Line rate (upstream) in previous 24hr period
Minimum line rate (upstream) in previous 24hr period
Maximum line rate (upstream) in previous 24hr period

The days monitoring file covers the period 00:00 to 23:59:59


or did...until this week
 
Yeah, much better with 2144 here as well. With FTTC DLM either being temporarily suspended from operation or terminated permanently (due to ASSIA patents court case), although I can't control the upstream interleaving (thank god I'm not banded on upstream) at least I can override the parameters on the downstream and still set that up to speed I pay for (and disable interleaving should I wish to).

One other thing I've noticed is that a short time before BT supposedly disabled FTTC's DLM is that Zen Internet's now tracking my changes in sync speed beyond the banding set by DLM. Prior to that it didn't seem to track my changes in sync speed beyond DLM's banding (although the IP profile updated).
 
I've had to go back to using the OR modem, I am racking up approx 3000-4000 CRC's per 35 seconds forcing re-syncs every 2-3 min's. On the OR modem no re-syncs. Do you guys think there is a major issue with my ASUS router, is anyone else getting that amount of CRC errors? I'm finding this on 2139 and beta 2144.
