Can anyone advise what settings to use though?

Its only been running for 2 hours on Sky Fibre and already has 16025 CRC down errors!! Only had about 300 in nearly a month on BT.

Thanks

That is going to get DLM making changes to the line ASAP...

Could you have been interleaved on BT but since switching to Sky, A possible line reset so running an open profile at present?

Yes my line was interleaved on BT and Sky is now showing as Fastpath. Is this what you mean and if so what does it mean if I have an open profile?

When you was on interleave it was correcting the errors hence a lower count, Fast path there I no error correction if it's like Adam hence the higher error rate. Open profile I think might meant as fast as the line can go. With the amount of errors your getting DLM will kick in and put you on interleave more then likely S the line should in theory be stable again.

I would just leave it be for 24-48 hours and see if it decides to stabilise. Don't try rebooting to make it stable, It should sort itself out although may apply interleaving.
The higher interleaving level applied the higher FEC's you will see but lower CRC's in theory.

a router wont affect CRC errors, a modem might tho.

Hi

I've just posted this over on the SkyUser forums as someone had the same issue there. Has anyone seen this before and have any advice to resolve it please?

Hi

I've just had exactly the same problems as ruddyrum. All was working fine then this morning I wake up no internet connection. DSL line is showing as up but internet connection is down with a message in the log of 'ISP's DHCP did not function properly'.

So i've plug the Sky router back in and all works perfectly so there is nothing wrong with the broadband on the line. Nothing has changed on the DSL-AC68U but for some reason now it can't get an IP from Sky's DHCP.

What I have tried is to static ip the DSL-AC68U using the IP details the SKY router picks up when connecting. This gets the DSL-AC68U showing an internet connection but when you try to browse a page it gets a DNS errror.

Can anyone help please, or RuddyRum if you can tell me if/how you solved your issue, that would be great as its frustrating to say the least.

Thanks

It sounds like something Sky have done.

The only time I've had that situation with BT Infinity i.e. no IP, was due to a BT fault in the area.

Though in your case you say the Sky router/modem is picking up the IP address fine? That means either 1. your device is broke, or 2. Sky have changed something in the way they give out IP's.

I wonder if anyone else on the network who use the ASUS DSL-AC68U device as had the same problems. I wonder if the guy who replied to you has your device as well.

So far in the fibre world this seems to be the most annoying aspect. ISP's trying to lock down their network, and generally being either secretative, or dumb when it comes to their staff.

I hope you get this problem sorted. I know how distressing it can be to lose an Internet connection that as always been there.

Have you cloned the Mac from the SkyRouter and placed it onto the ASUS DSL-AC68U in the WAN Section?

I hadn't previously when it was working. I tried that this morning when it stopped but it didn't seem to make any difference, should I have left it longer?

Thanks

my rt-ac68u is still working fine on sky and I didnt clone the mac.  Regardless the post is concerning.

I wonder if its related to changes they making in preperation for ipv6.

--edit-- I wonder if been on a static ip saved me? as sky manually configure static ip's meaning changes to their automatic configuration wouldnt take affect.

Remember his is using the DSL modem portion whereas you are using the RT one.

I remember seeing this full reboot procedure. A total copy paste from another forum but worth a try.


1)With the Asus switched on, press and hold the reset button for 30 seconds.
2)Without releasing the reset button, unplug the Asus (pull the power cable from the back) and carry on holding reset for another 30 seconds
3)Plug the Asus back in STILL holding the reset button a final 30 seconds
4)Release the reset button.

Its best if you do the above steps BEFORE AND AFTER any upgrading if you have any issues with firmwares.

If the Asus enters recovery mode then press the reset button again with it powered on then release the reset button. Power the device off and back on.

Following the above is not normally needed but that will ensure ALL prior settings are erased and anything in the Asus RAM or any modem for that matter is completely cleared.

found your post, the other guy was not recently, so both occurrences were not today, so I think you have a local issue of some sort.

I would expect both the dsl and RT model to use similar code for authentication.

However with that said merlin improved the dhcp authentication so it works well with sky and the dsl models dont have merlin firmware (I use a fork of merlin's firmware), so I think thats probably the reason.
