So I decided to make this thread to avoid cluttering other threads.

Long story short,
Ogero FTTC cabinet is like 50m away from my house.
I was on ogero DSL (15/1mbps connection) but with interleaving off, my ping in most games was around 50 to 80ms.
Then I switched to VDSL (30/9mbps connection) and my ping immediately jumped like 30ms at least. No hardware changes whatsoever neither from my side nor from ogero side.
Called them many times after that to turn interleaving off and they confirmed that it's already off.

I expected much better/lower ping with the better upload. So what is it all about? Is that a known issue with VDSL? Anything I can do to keep VDSL but get the better ping I had before?
It is a DLM issue , sometime it can add up to 32 ms of delay

Have you checked the modem info for interleaving?
DLM is not VDSL exclusive.

there is no DLM in lebanon on adsl and am pretty sure it is same on VDSL i might be wrong though , they only use fixed profiles
@lifeengineer post your stats
why don't you post traceroute... it tells the whole story.
Just call "tracert 8.8.8.8" in Windows command line
Is that good?

Also in my router settings, there's the Network/DSL settings page, having those values:

For DSL Modulation Type there are these options: Auto Sync-up; ADSL Auto Sync-up; VDSL2; T1.413; G.dmt; ADSL2; ADSL2+.
As for Annex Type there are these options: Annex A; Annex I; Annex A/L; Annex A/I/L.

Sorry I'm not a telco guy (although i love tech and have some minor idea) but this is a bit much for me.
What does all that mean @Beta0?! How do I get such table?! Am I doing anything wrong?!

Not all modems show much info unfortunately, the table shows interleaving status, 1 is disabled, I don't know what hardware you're using.
I posted traceroute for a simple comparison, did you get ~60ms on ADSL2 before? You can change the modulation back to ADSL2+ and test. ("Auto sync up" field)
From my router status:

Never tried such command on ADSL.
I will try that and see. Thanks for your help mate
Once you are on VDSL, you can't change back to modulation to ADSL.

Did they change your port (cabinet) when you requested VDSL?

You have interleaving ON....

I really don't know. Can I know figure that now somehow?!
Kareem wrote You have interleaving ON....
May I ask how did you know that?! (just so I know what to tell ogero guy when i call him)


When interleaving is ON there's a 20-30 ms to the first hop outside your network. When it's off it's in the few ms range.
