Anyone Using an Asus DSL-AC68U

It should be, still don't know what I am on be it Fastpath or Interleaved as the Asus stats seem to lie sometimes...

With an interleaving depth of 1238 you're definitely interleaved.

Having used the Fritz!Box 7490 and suffering random crashes at the moment I've temporarily switched back to the ASUS and overridden the downstream DSLAM settings. Max sync rate 80Mbps, INP 3, delay 8ms.

I've also set tx power to -2 dB, Rx AGC to stable, and target SNRM to 9.0 dB. I'm using the latest unofficial beta firmware (2182).

Having read the whole thread, I'm going to give the DSL-AC68U a miss for now, the problem is there's nothing much filling the gap.

The Billion 8800AXL is next on the list, but the wireless signal has been noted to be a weakness.

I'm a bit sad I've nothing to play with to replace this Super Router.

I'm weak.

A combination of the wife now being away for the weekend, Quido £50 credit to the rainforest and their simply untouchable returns policy, I've just ordered one.

Should it have any issues of note after a couple of weeks, it can be sent back without a quibble. The fact they even send a courier round to pick it up free helps.

So on arrival it's flash 2160, do I kill spectrum or leave it now days?

Short line and connected to a Huawei cabinet, had a 612 running for a couple of days, and had no errors of note too report.
 
As far as I have been told by Asus spectrum only runs when you go on to the spectrum page on the GUI and ask it to run. I am not sure if turning off Spectrum will actually do anything. I did ask Paul from Asus about this and that was his response. Not sure if this helps but thought I would pass the info along.

welcome back :)
Apart the crashes, how is going the 7490 with your line which matches it?

Works fine apart from the random reboots/crashes.

For the ASUS, it seems to be fine other than the abnormal FEC (on the latest beta firmware). Will reduce INP later on.

Haven't killed spectrum via telnet either.

Anyone tried the Fritzbox 3490? Its apparently the same inners as the 7490 but without the built-in hardware to manage DECT or analogue telephony. Price is £130 so cheaper than the 7490. Still looks pretty poo though.
 
DLM kicked in last night, I can only assume it's related to the very high downstream FEC as the ES+SES combined values and resyncs were well within the threshold. I can't think of any other reason for it.

Old profile:
Downstream - 128/54000, INP 6, Delay 16ms
Upstream - 128/20000, INP 0, Delay 1ms

New profile:
Downstream - 128/49000, INP 7, Delay 16ms
Upstream - 128/20000, INP 4, Delay 8ms

If it follows the same pattern as before then the upstream interleaving should disappear within 10 days, downstream will remain the untouched though.

Other than that, it seemed to work fine.
 
Is the interleavedepth figure actually being read correctly by the asus? If dlm resets after ten days I should be back on fastpath, but the interleavedepth, according to some, suggests I am not. Perhaps the only way to tell is to reconnect the bt modem then test my speed?
 
Yes I know that I should be able to tell by my ping times, however despite my modem being up for over a month my ping times have always been the same since I started using this modem and they have never changed in the three months I have owned it for. If I am on interleaved then why doesn't mine reset to fastpath after a period of time. I do not suffer from any resets by dlm since the earlier days of owning the modem and my stats should be fine. Should I contact Sky and see if there is anything they can do?

Maybe DLM regards your line as stable with a step up of interleaving. Its hard to say. I'm no where near experienced enough to give you advice compared to the other folks on here. What they speak of goes right over my head!!!

try a tracert to bbc with windows cmd

the first hoop is from the modem
if the second hoop (to the cabinet) is below 20 ms it should be fastpath ... or i am wrong with vdsl?

hmm strange, as far i notice users are with broadcom seems better, you are with infineon ... is my speculation so i can be wrong ... leave the other settings as it is and just change the AGC Gain from the normal (default if you are using 2182) menu to other value (testing if you don't mind)
That feature is complicated if not adjusted correct ... was reading an article can cause errors

Depends on the ISP these days:

BT - when I first got FTTC installed, the 2nd hop would respond to pings and could be used as a measurement of fastpath -v- interleaved. Middle of last year I think it was, BT started making changes meaning that this would no longer respond to pings. And I think latterly before I changed to Plusnet they were doing a similar thing to Plusnet as below

Plusnet - first ping is their gateway in London.

My pings to the Plusnet gateways are around 23 - 25ms depending on which gateway I hit. I am on fastpath but the reason for the pings being as they are is that I'm 500+ miles away.

So it's not hard and fast that under 20ms is fastpath and over 20ms is interleaved as it all depends on what the 2nd hop is these days.
