Asus DSL-AC68U do not connect to SKY ISP

[Peppe+I]

Good evening all,

my Asus DSL-AC68U cannot connect to SKY ISP - please help me it's 3 days/nights I am browsing internet and I cannot find any clear instruction to solve this issue.

THE FACTS:

When I try the setup wizard, the DSL link status is always down (let off) and I get a message to check the cable but the cable of course is properly plugged in the device and in the Sky socket.

Then, I tried to configure manually the connection acting on the DSL settings but I don't have the sky authentication programmed into it. I've read in some support blogs that there should be a drop down menu with the preconfigured sky broadband authentication but in the drop down menu of my device there is only turk telecom .........

The firmware looks like to  be the latest one

Please help me to replace the Sky RS204 with this Asus device; thank you so much!

What you are looking for is on the WAN->Internet Connection tab a field with DHCP Options and an Option 61 field that needs filling in with 'anything@skydsl|anything' without the single quotes. The Asus router you are using is quite old so may not have that DHCP Options field, if not then you'll need to flash the Asus with Merlin firmware.

Dear MAE-03 thank you so much for your support!

I 've found the OPTION 61 field, filled it as per your instruction but it is not working.......

I still get the message that the cable is disconnected ....... (Link down and DSL led off).

Do you have a link to download the Merlin firmware ?
Which Merlin firmware version should I use ?

Thank you !!

The DHCP Option 61 field is filled in incorrectly, eg: should be 'anything@skydsl|anything' note the pipe '|' symbol after the skydsl bit and clearly without the single quotes. And the DHCP query frequency should be changed to normal.

You will also need a VLAN setting on the WAN side of the interface of 101.

Dear MAE-3 thank yoou for your pacience; it didn't work for me.
Also I tried to flash the Merlin firmware but I get this message (also after turning off and on the device).

Any other solution?

Thank you

@Peppe+I 

Waiting for the screenshot to be approved. Did you set a VLAN on the WAN interface of 101?

[Peppe+I]

I understand that the Merlin firmware is only for Asus RT devices (only routers not modems) and this is the reason that my Asus DSL AC68U don't upload the Merlin firmware.

I've found and flashed on the device the GNUTON1 firmware (https://github.com/gnuton/asuswrt-merlin.ng/releases/tag/386.04_0-gnuton1) but also this one didn't work; no drop down menu with the preconfigured sky broadband authentication.

Now I've flashed the latest ASUS firmware but no changes; same situation. I cannot get the connection to the ISP.

Above the latest DSL config used without success.

Something missing or wrong? Any idea?

Thank you

At the bottom maximum mtu is 1500

@Peppe+I 

Also try changing vdsl profile to 17a

[Peppe+I]

Hi coockiemonsteruk, thanks for your suggestion but I am not finding the field/menu to choose this option.

[Peppe+I]

I've found and modified the VDSL profile to 17a but it didn't work. 😣

Any other suggestion?

Thanks

Have you sorted this issue with DSL-AC68U yet?

I'm having the same problem,

I've used the dsl ac68u for years with no problems,

it just worked like an absolute trooper, with stock and dsl merlin firmware 

today changed some WiFi settings and restarted the router, heres where my problems started,

it just won't connect, but it works with my sky router so its not the cable or box on the wall,

set all my settings to advised above, rerun the setup and set to annex a, but still no joy
