Anyone Using an Asus DSL-AC68U

ViRuS2k · 13 Dec 2014 at 17:51

Strange, no issues here for me on the latest firmware.
weird the closer i am to the test server the better the upload is and download but the ping is higher
the further away the server is i get just as much download and slight loss in upload but much better pings very weird lol

also i currently get about 100crc`s per 24 hours... and i have had no disconnects and my connection has run pretty much super stable no issues with dlm or anything.

Mmm, I guess then I'll have to wait until the dlm resets itself, how long will that be? It's shame because I only had two or three disconnects caused by the modem and that was very early on, the rest have been caused by firmware updates and before the last one three days ago the modem had been up for over 10 days. Perhaps I should stop doing them but then that's the penalty for being an early adopter...

Most likely at least 14 days since you were interleaved. It also depends on your daily error seconds count and your line history (DLM).

I just don't understand. You must be using some miracle setting or something. Do you remember what settings (any on the router, not just DSL specific) you changed when setting up the router? I'm probably stabbing in the dark here but it's the only thing I can think of, other than still considering it being the power supply.

ViRuS2k · 13 Dec 2014 at 18:05

i will check my other settings as for the dsl settings there all default lol
just checked, all settings are default apart from me setting up wireless and adding those wireless devices mac address`s to the dhcp list to by pass it. everything else is default, my connection settings are just the 101 and assign auto dns setting and connection automatically ect.

i should also note that i have installed a professional cat 7 cable from my main socket to my router in the bedroom where my pc is, also there is a MKII bt open reach socket installed even though i have a MKIII socket in the drawer never been used, and bought just in case there where issues but i never got any.

i would suggest though that those people with old sockets or first gen adsl or people with adsl sockets get a MKII or MKIII socket installed asap as these have far better filtering.

Ok thanks, OR have been installing new cables to our village for a while as well, don't know if they are fibre or not but there also has been some disconnects during the day that I think we're down to them.

How many meters is the cable from MKII to your router?

The cable is 20 meters in length.

Somebody mentioned that it could be high FEC's down causing the disconnects. I just pinged bbc and got 17ms....

High HEC errors can cause instability and re-synchs but you don't appear to have any. Bitswap errors could cause it perhaps?

babis3g · 13 Dec 2014 at 21:33

i know is for adsl but anyone tried the ADSLNation XTE-2005?
Was reading is suitable and for vdsl

Also will work if you take out the faceplate of the BT socket and connect it direct to the test socket with out phones?

I've added some more ferrite clip-on's to the power cable since yesterday (I think I've got 6 or 7 on the cable now), disabled 3G/4G modem support, disabled reduced USB 3.0 interference in the professional wifi 2.4GHz settings, and here are the results for INP 7, delay 16ms, max sync 49Mbps at target SNRM of 12dB with a Rx AGC Gain at 'Stable'. I've also moved my DECT phone base further away just incase that was causing some interference.

Tbh the power supply seemed very flimsy to me slotting pieces together dosent exactly fill me with confidence...

cuke2u · 14 Dec 2014 at 10:32

It seems that's quite normal with power supplies these days, I work as a IT technician in some local schools and just installed some 20 Aver visualisers that all came with that type of psu.

Still looking good after two hours uptime in comparison to even the HG612's FEC count on the same setup (which averaged around 3000+ FEC every minute or so).

EDIT 1: Getting a bit of interference now, nothing as bad as it was though. Just what looks like one or a few tones around before 1536 have dropped in SNRM. I also linked this to a small spike in FEC. Bitswapping has done the task of dropping the bits for the tones. FEC isn't rising continuously still and is still reasonable.

EDIT 2: FEC is now rising rapidly again, over 8 hours of uptime. Noticed that the SNR on the tones I mentioned is fluctuating a little wildly which makes me wonder if this is linked. But the big question is what's causing this to happen and whether the bitswapping algorithm needs improving to perhaps to delay consideration of using tones which have a high level of unreliability (if it's linked, which certainly seems like it might be).

Mines been stable for days now using default settings but with profile set to 17a and a 5db target snr. Prior to 2155 I was getting disconnects and high crc.

I was wondering if it was possible to set a 4db target snr?

MikeBee · 14 Dec 2014 at 21:30

Hi All,

I'm considering this router to replace the OpenReach modem and Billion 7800N I have for fttc with Zen. I've tried to read through this thread but it's pretty vast. My current connection is rock solid at 70Mbps down and 22Mbps up. I'm not specifically looking for more speed but I do want an integrated modem router with ac wireless.

Do people think this router with latest firmware is ready for this type of use?

Thanks.

Yes it's possible, but perhaps a little complicated to do. Do you know what the Chrome developer console is (press F12 to open it, assuming you use Chrome)?

It's hit and miss. Improvements appear to be being made at the moment with each firmware release, but there are still some people having issues with this device when it's on a fastpath connection (stable on interleaved). I'm almost certain I've traced the cause of my downstream FEC going sky high, just I'm not sure yet what can be done regarding a fix as I believe this is also the cause of instability when on fastpath (might still be up to ASUS to produce a different bitswapping for example).

That interference on the tones I mentioned is currently not present. A pretty clean connection at the moment.

That's looking very clean now, I am sure its the power supply.

I believe it may well be related to the power supply.

Although the interference has returned, it's not as bad as it was in my view. But once this interference shows up, the FEC goes through the roof (which I believe is linked to those tones going odd).

Below is my current one, with FEC going through the roof:

It's next to another ASUS power supply for my N66U, so later tonight I may try putting distance between them both. I sure wish I could find an alternative power supply of the same or higher spec.

EDIT 1:
Wow. Look at that drop.

It is frustrating not knowing the full answer.

Hi All,

I'm considering this router to replace the OpenReach modem and Billion 7800N I have for fttc with Zen. I've tried to read through this thread but it's pretty vast. My current connection is rock solid at 70Mbps down and 22Mbps up. I'm not specifically looking for more speed but I do want an integrated modem router with ac wireless.

Do people think this router with latest firmware is ready for this type of use?

Thanks.

I had the DSL-AC68U and had nothing but issues with it. It resulted in DLM capping my profile 6MB lower than what I got with the HH5 (28M down to 22M).

I've since started to use the Billion 8800AXL which has AC wifi. WiFi range is not as good as the DSL-AC68U but its good enough for me. Line has been connected for 16 days with 2 line resyncs due to DLM increasing my profile back to what I had before.
