I am on TM Wholesale network.

TM say they give best effort to their customers by providing them the fastest speed achievable for a plan.

Why if I subscribe to other ISP which rides on their wholesale network such as Maxis, DiGi or Celcom I will get less than my subscribed speed? Even on 30M plan?
Easily I can get more than what I subscribe because fibre no problem until 300M at least.

Why my friends on Allo, TIME and Maxis own fibre can get extra than what they subscribe?

This is not call BEST EFFORT but calculated short changing consumers. Extra few megabits also want to deprive your customers of lesser speed?

it's kinda well known that you will never see 30Mbps on another ISP riding TM infra. They probably do this for an unfair advantage and just blame it on your modem/router/device.

This speed difference will cause the consumer to think "hey maxis is only giving me 28Mbps, but Unifi give me 33Mbps, Unifi better"
When in reality is TM doing the manipulation
Also if you notice, when you subscribe to Unifi, they use LAN port 1 of the modem, where as with other ISP's, they will use LAN port 2.

I'm on maxis own infra, I see 38Mbps on my 30Mbps plan.

Not sure if anyone ever tried reporting this to MCMC.

Anyways, Anime4000 has tried tinkering around with the modem before and found some interesting stuff (the speed cap being set and stuff), maybe they can explain more.

All other wholesale networks by default universally will set their modem/BTU port to duplex 1000/1000 speed.

Only your user account will limit this speed when assigned to the user for simplicity.

So if you decide next day to upgrade your plan speed it's just a few mins request over the phone, ISP just needs to update your account and voila you see the speed changes after that.

I know because I saw my friend's place installed with TIME/TNB Allo just swap user account with test account can jump from 100M to full 1Gbps to test line.

Why TM make life hard for themselves and their customers?

This is not BEST EFFORT at all. For low plans like 30M/100M on fibre getting 100% speed of what you subscribe with a local test server is inexcusable.

Few megabits for your customers also you want to short change them tells that the company has very bad ethics and policies.

Actually GPON (fibre) tech is max 2400/1200

But most modem are gigabit

On Allo if you have a higher than gigabit modem you can get further speeds on the 1Gbit plan I've heard since they were expecting the modem to be the cap

I have tested this on friend Unifi, 100 and 300

Unifi 100Mbps Home with 300Mbps account get 100Mbps

The way TM manage their OLT with added T-CONT (Transmission Container) Type 1 or 5 to make fixed bandwidth (physical link speed)

T-CONT come with
1. CIR (Commited Information Rate/Guaranteed Rate) [Subscribe Speed, Unifi get extra while other ISP get less]
2. PIR (Peak Information Rate/Shaping Rate) [Burst/Spike Control, reduce Bufferbloat issue]

This way can prevent Unifi users swapping account and over use bandwidth.

So, TM put exact bandwidth value on T-CONT making no room for overhead

There are way to override T-CONT, but need to know your GEM/T-CONT Queue first.

Here my GEM, T-CONT Queue


T-CONT Queue




Previously my 500Mbps speed way less, like ~484Mbps like that, after set various command, I just manage get extra download but not upload... surely something with OLT

TM really make life hard not only for their customers but also for themselves.

If they wanted to prevent account swap by unauthorized people and irresponsible agents/installers, there are better ways then to implement GPON GEM like this.

One solution is to set a slightly higher speed for their BTU to match the subscriber's tier plan such as 100mbps for those subscribing 30M/50M plans. 200mbps for those subscribing 100M plans, etc.
Always set the BTU port higher speed than the ISP subscribed account.

Second solution is to seize control of authentication such as what TIME and Allo City Broadband is doing now. The ISP will configure the login credentials remotely for your BTU and the customer does not need to do anything accept to plug in their own router to receive DHCP addresses directly for their own home network.

The BTU/all in one fibre modem can be configured in either standalone router mode or into bridged mode if customer wants to use own home router.

That way they got their unauthorized account swapping issues resolved and made life much simple for everyone.

As I know Allo and TIME now use this newer authentication method not unlike TM which still use the outdated PPPoE method.

Also, stop using PPPoE, such inefficient protocol, they should use "802.1x" or "DHCP Option 82"...

Even like Viewqwest on HSBB, had to follow TM Wholesale rules, so, Viewqwest had to use PPPoE instead of DHCP Option 82...

nah... Malaysia ISP wont to this and that, TM brain are very small that's why...
