ASUS DSL-AC68U Settings

Morning,

Could somebody just have a look at these DSL/VDSL settings for me and just make sure they are correct (the best options)

I'm on the unlimited fibre package.

Thanks,

Richard

rharris118, I would advise against using any of the DSL-AC68U's Dynamic Line Adjustment features (as you appear to be); as they will almost certainly 'fight' BTOR's own Dynamic Line Management system. Set these values to 'disable' or 'default'. The Asus features are intended for environments where the VDSL service does not have its own software to monitor automatically the stability of the connection.

I use settings as per the attached screenshots, which work fine for me.

SRA should be enabled according to BT SIN 498. SRA is a fairly harmless feature to leave enabled while nothing is currently making use of it.

EDIT: ejs, I'm sure you're right and there's no harm in having SRA set to 'Enabled'; although the SIN 498 document seems to only require this for ADSL. IIRC SRA has never been actually used in the UK except (possibly) by the now-defunct ISP 'UK Online'; I've never understood why SRA wasn't adopted more widely.

Re the OP, I also found this interesting sentence in SIN 498:

"It is the DLM system that sets the line profile, and this should not be interfered with by CPs/users setting rates, SNR margins etc. at the modem."

Should the Profile setting not be 17a rather than 30a?

No, it's R.VDSL2.9, which applies to VDSL2. G.993.2 is VDSL2, G.992.3 is ADSL2. (The ADSL2+ section of SIN 498 is probably completely irrelevant now that they're working on LR-VDSL instead for the really long lines.)

Profile 17a or 30a doesn't really matter, because it's one of the things where 17a will end up being used whatever the setting is. There's no harm in your modem also having profile 30a enabled.

Thank you. I've used the exact settings on your screenshot. Lost 3meg on the sync speed but downloading at +5meg

To be honest, I would look at stopping using that router as a modem and move to a two box solution.

Depending on what cab you are on you will never get G.INP with that router (Huawei cab needed).

I have that router, and I was plagued with issues, and since moving to the 2 box solution with a Zyxel VMG-1312 box. I gained G.INP and 20Mb in additional speed and sync.
