Has anyone had an official update from Asus. It's now over a week that they release beta firmware that is clearly not resolving everyone's issues. I've gone back to using the HH5 and surprise surprise DLM has reduced my line.

I've switched to the HG612 temporarily - due to the concerning stability issue yesterday from 4pm. Still getting the trickle of CRC errors but the Hlog and QLN I don't believe show anything unusual to identify a possible fault unfortunately (am on 'MyDSLWebStats' as Ixel). Just reconnected a moment ago now that the trickle of CRC errors is rising as usual, nothing still identifiable on the Hlog or QLN :(.

EDIT: Just got the MK3 SSFP about 30 minutes ago, reconnected again as I wanted to swap from MK2 to MK3.

So far I can't say it has made a noticeable difference to the trickling CRC's. Lost a bit of attainable though.

Studying the TC Console instructions, it appears to open up access to the modem's operating system/firmware via LAN port 4. Telnet access becomes available on IP 169.254.0.1. I'm able to get in with the login admin - 1234

At one time I was at 10000+ CRC within 5 minutes :P.

EDIT: I've just figured out how to use the TC Console interactively. Going on telnet is no good as the commands return nothing back to the interface. All output seems to be redirected to the TC Console application. You can set tc diag from 1 to 0 in order to make it so you can type commands such as 'wan'.

I've just captured a 24hour log which contains several re-syncs and hence DLM reducing my line. Hopefully this will provide them with something to work on.

Asus has now been locked in the cupboard until this is resolved.

Can someone please give me the email address to send this log to.

Thanks

My ASUS seemed to be fairly stable using these settings:



At the moment I'm torn between two bits of kit, a ZyXel and the ASUS.
The ASUS reports a max attainable speed of 75/25 the ZyXel 69/22.

The above settings stablised the ASUS connection to produce just 0/3 CRC errors in the first hour.

I see. Well, if and when DLM restores my downstream sync rate then I'll go back to the ASUS. At the moment I'm on 49/20 (was 49/15, from 74/20). I have a feeling I could be waiting a couple of months though, so may have to try it sooner. I'll give it up to one month of solid uptime on the ECI modem, if nothing has changed then I'll go back to the ASUS and try that or whatever's been said at that time.

For those near max sync, adding stability adjustment of 6db probably helps. However for those like me that only get around 26M, adding a 6db stability reduces the downstream to around 20 which kind of defeats the whole purpose of this.

Sent the 24hour log off to Asus last weekend. Really disappointed that they have not even bothered to reply. Not good!

I've not heard anything either for over 12 days.
I might drop an email to them to see if there's any progress.

Update: I've decided to sell the ASUS on eBay and stick with the ZyXel VMG8324-B10A (f1000).
The ZyXel whilst not as impressive in hardware specs is reliable for me now.

I got a reply this morning. Clearly they only have one representative who has been on holiday.

He sent me the same beta firmware again, so I guess that means NO PROGRESS.

The only feedback I got about the 24hour log was my max speed and distance to the cabinet. :no:

I also wish they would stop telling us to play with the stability adjustment - setting target S/N should be left to the DLM. This is the only device I know with stability adjustment (maybe for a known reason).

I guess that's Paul Lee they are referring to.

They sent me those settings also, but to be honest they shouldn't be needed to make a connection stable. The ZyXel box I've been using recently doesn't need them and I get far less errors, plus I now have more confidence in it holding the connection with the latest firmware. I'm tempted to try returning the ASUS to PC World as unfit for purpose.

I stuck the ASUS back on-line yesterday for 12 hours and despite maintaining a connection all day DLM smacked me down by 2mbps, so the 2mbps I gained last week with the ZyXel was swiftly taken from me as punishment. The ZyXel is back in place so hopefully by Wednesday I'll be bumped up again.

Hi,

I just bought this modem-router

I'm surprised  :'(

DSL-AC68U does not support the loopback?  ???
