I subscribed in one of the ISPs in our country (Saudi Arabia). 

 

The service is VDSL2 with 20 MB down and 1 MB up. Everything is satisfying expect that the ping is higher than normal. It is obviously noticed especially when I play games like overwatch, cod or battlefield. 

 

This is the only problem that encountered me since the beginning. STC which is my ISP is really strict. Thier routers don't provide the information needed to monitor the line. Such as the Line's Profile and latency. They are trying to fools us for some reason, but with a little tweak, I was finally able to reveal the statistics of my line. 

 

These are the statistics after a little tweak through inspection (one of Chrome's features).

 

Here are few notes about what I noticed:

 

1. The VDSL2 profile is always fixed to 17a for some reason. 

 

2. There's a delay in the Down and up delay boxes. 

 

3. Although my line could attain up to 100 MB, I am stuck with 20 MB because of their stupid packages.

 

 

 

These were some information to clarify what I'm going to ask. 

 

Recently, I contacted the ISP (STC) to look for a solution for the ping (45 with our local service in Speedtest). They fixed it through decreasing the Downstream speed from 22000 to 20000 as you can notice in the statistics. Surprisingly, the ping is decreased 

 

Surprisingly, the ping is decreased to 30 and even 29!! And nothing changed in the statistics except the downstream as I mentioned. 

 

My question is what is the relation and what actually happened? I searched a lot, but to no avail. The only forum that was helpful is this one! 

 

The pinned topic about VDSL Information and Tuning was really helpful that's why I posted the question in this forum. 

 

Thank you in advance for your help .. :)

They changed you to a profile that doesn't have interleaving on.

 

VDSL profiles generally prioritize stability and high speeds over latency, but since your line is so good, changing your connection to a profile with lower latency and less speed isn't a problem, as you're still over the 20Mbps offering.

but the profile as I mentioned is always profile 17a. Even after they decreased my speed.

I believe interleaving can be enabled or disabled on any profile.

In another forum, someone posted his statistics and it shows the type of channel he is on! I believe they did the same thing they did with my line. The down rate decreased and the ping went down from 25 to 15. 

 

Here are his statistics:

 

 

 

 

But VDSL doesn't use a channel type. What might be the trick here?

Everything went back the way it was, unfortunately.

 

I contacted the ISP once again, and they said it's set automatically and there's nothing we can do about changing the interleaving depth! 

 

I need your help and ideas on this guys.

Interleavings is there for a reason.

If your rsp is not able to request it to be turned off that will be the conditions set by the network management.

Bandplan profiles have nothing todo with latency at all.

Does your ISP offer ADSL2? Presumably they can since they offer VDSL. Since you have such a good line, ADSL2 would probably still give you similar speeds to VDSL that is capped to 20/1 down/up. And then they can set the interleave depth to 0 - so lower ping.

 

I also had a look around the STC website. I guessing that you can't get Fibre where you live? If you can then that will give you far lower ping. Also I see that STC offer an option where you can pay extra to get a higher upload speed. Up to 10mbit for copper connections instead of the standard 1mbit. Your line rate shows that you can get the full 10Mbit. Have you tried paying for the extra upload to see if it makes a difference?

I can't go back to ADSL2, unfortunately. The upload key they offer is not for copper connection. It is made only for Fibre connections. I know that nothing makes sense about their packages!

hio77: Interleavings is there for a reason.

If it's as you claim for a reason, then why my friend has an interleave depth = 1? My line statistics are far better than him!  

 

He requested it himself, but it was weird, to be honest. He asks the technician specifically to change the channel type into an ADSL fast profile, and it worked pretty well for him. 

 

I couldn't understand it at all. I mean can they alter the profile values such as INP or Interleave depth or even disable it?

 

Today I requested a new router. Look at my stats. There's a channel type! 

 

 

 

 

 

 

This router fortunately shows the depth of interleaving.
