is it really bad for having private IP? Google can answer my question.

But after I make a complain about my speed and ask them is it change to private IP they told me no such thing. So how to request to change.

Better use TM LiveChat. Don't complain about speed. Just complain on why you can't access your CCTV remotely.

Some support agents on duty have no idea about these stuffs.

Screenshot your assigned IP address at router/modem configuration page. Upload to TM Live Chat.
Ask TM Live Chat on why your modem/router is assigned with private IP instead of public IPv4 address.

Okay, so here is my follow up on live chat + technician coming over and informing them about dsl noise profile that can only be changed on TM side stuff few days ago.
Oh ya, I create the report on monday 20/3/2017 and it was changed just now 22/3/2017.

Before (Interleaving mode)




Today (Fastpath mode)




for Miri City TM technicians.

Edit: Note that I don't get charged...okay....
Edit2: Replacing pictures with PNG version because lowyat JPEG compressor quality is disappointing....

That is given that there is only one user is using the connection at a time. Tell us how to do iCloud backup, Facebook live, video upload with that upload speed, even if there is nobody else is contending the connection with you?

Seems like if I go from Interleave to Fastpath, it can give me better pings? Question, how do I check which am I on?

Upstream Downstream
Current Rate (Kbps) 637 10237
Max Rate (Kbps) 1140 26680
SNR Margin (dB) 25.3 22.8
Line Attenuation (dB) 6.4 6.5
Errors (Pkts) 0 0

Are these stats good enough to request the change to Fast Path?

Login into the modem/router and check the adsl stats.
Dlink, asus and tplink display "Interleave Depth" value for both upstream and downstream.
In my case, it was 64 depth downstream and 8 depth upstream
If you use TM supplied innacomm, then you out of luck.
Notice how much delay/latency interleaving by taking a look at "Delay (msec)"
When my adsl line was in Interleave mode, the "Delay (msec)" were 7.85ms for downstream and 7.91ms for upstream.

Once it is changed to fastpath, Interleave Depth is 1 for both upstream and downstream (depth of 1 means fastpath). The Delay (msec) for both downstream and upstream become 0.25ms and 0.24ms respectively.

Some people is unlucky, for example, the forummer HolySatan here:

Source: https://forum.lowyat.net/index.php?showtopi...post&p=84153387
His "Delay (msec)" is....... 15ms for both downstream and upstream. Total up 30ms latency. His adsl noise profile probably is configured at maximum stability mode.


25.3 with 6.4?
22.8 with 6.5?
Yes, stable enough.


EDIT: Anyone with SNR (upstream and downstream) lower than 25, don't bother changing to fastpath. Otherwise, the dsl line will be forced to retrain randomly due to error/noise/low signal (layman term, dsl light will be unstable) or there will be a lot of packet loss.

Oh dear, I'm on interleaved mode 64 and 8... so that's why I'm getting high pings for my online game!

Well, with my ADSL stats I should be able to request for fastpath?

Only 1.4db attenuation for upstream?
Sure, no problem. Upstream SNR 23.4 should be fine since the attenuation is quite low. If your attenuation is more than 10, then better don't change. Luckily it is only 1.4db. Must be new copper wire........

But seriously......you better hope the technician at your local DSLAM exchange know how to change it.

Changing "interleave" to "fastpath" can only be done on TM side, not user side.
No need to ask TM technician to come over. (TM charges RM50+ for each visit, in my case though, TM technicians came over and I explained to them about dsl interleaving,fastpath, and depth value plus how those things have impact on latency, when fastpath or interleave should be used and how it can be only changed by TM since TM doesn't expose such setting to user unlike Australia Telstra ISP. I showed them Australia Telstra website too. I don't get charged for the visit. They said they will refer to their senior and voila, mine got changed to fastpath the next day )

About 4-5 years ago pulled the cable to my home for the coolunipack thingy... that's the cable you referring to? But I think the DSLAM is pretty close to me actually.

Hmm, think I gotta make it known to them about this then... get them to refer to their senior haha!

JohnLai That's some really competent technician you have over there! Pretty significant improvement on latency as well. Do report back if you face any issues.

Anyway, my 8Mbps Streamyx is on interleaved mode. I realize cable quality is really important. I lay my own telephone cable and I use a decent splitter. I use the cheapest TP-LINK modem so I couldn't check the depth.

SNR Margin : 24.7 18.1 db Line Attenuation : 7.7 4.4 db

So far, so good,even my parent also said their internet browsing (through wifi) is quite responsive than usual today.
Except the part where my area IPv6 connectivity still borked since October 2016.........
Not really a problem as I can use HE tunnel to access IPv6 only websites.
The bad news, I might not be using dsl for long. Currently awaiting call from unifi installer. Installer may call me for installation between April to June.

True, copper cable quality is important. But with your current upstream SNR......don't take the risk of changing to fastpath.

EDIT: wah, even with interleaving, your 22ms ping is quite good. I guess 38ms is quite reasonable for my location in Sarawak.

I just disable IPV6 entirely. No incentive for me to use that for now.

I wouldn't bother changing, wouldn't fix what's not broken.

Hi. Do you mind sharing what type of cable and splitter you use? I want to improve my streamyx line. Thanks

mine already change to private IP last saturday.. call TM to change back to public.. they just ignored it..

Sigh, contacted live chat and requested to change from interleaved to fast path saying to reduce ping to online game but now they requesting for ping plotter ._.

What reason did you guys give for changing the dsl noise profile?

I got mine changed back to public IP.

Oh ya, livechat agent also requested ping plotter result from me.
I simply provided her/him with the result and clarify that the ping can be lowered further if adsl noise profile is set to fastpath. I also wrote the interleave depth is adding 25ms plus 5ms extra ping time. So, from the pingplotter result, there is total 30ms extra latency which is caused by dsl interleaving which is simply unacceptable for online gaming. I provided them the source for the info http://www.kitz.co.uk/adsl/interleaving.htm and http://www.juniper.net/techpubs/software/c...e-config31.html , at the bottom graph, had* the livechat agent took a look at 'burst protection' latency values because TM dsl line has it activated. In worst case scenario, interleaving can increase latency up to 47ms for depth value of 64 with INP value of 2.

You can check my interleaved dsl stats screenshot where my INP were 2.64 and 2.63 for downstream and upstream. In fastpath, INP is disabled.

EDIT: Some stuff for reading....how INP and interleave depth affect each other......fair use.....two pages only. Sourced from google book?

I would be able to identify how much ping is contributed by the interleaved mode? By saying ping plotter, it is referring to the app ping plotter right?

The live chat agent never requested anything about ping for me and they just make report to change DSL noise profile, I think they don't even know what it is.
