Check in the software that you used to do live stream, to limit the connection numbers to 500 or less.
With the 500kbps upload speed, that's the most you can. Some people recommend 350 max connections for optimum speed.

For uploads, limit upload speed to 80% of your max upload speed from speed test.
8M package cap at 8072, or 4M Package cap at 4096 constitutes a miscap.
If you are cap at you package speed, you will never get full speed. This is due to ADSL overhead. Generally, the cap has to be 20% above your package speed in order for you to get Max speed.

It is very hard to convince the techs this. Some CSR knows, but some ignore what you say to them. It used to be that the CSR is able to change the cap for you by contacting some of their internal teams. Now, only technicians are allowed to do it.

Is it possible to convince the technician to give me 8mb rate when they come to my place in this few days? Current rate is 2mb before I terminated 384kbps. I was opted for 4mbps but planning to upgrade to 8mb by the next month. Yet they haven't come to install. It has been 5 days .

how to limit upload speed to 80%?

for streaming using OBS use this setting?

Sorry, i don't understand.
You want 8M cap but you have 2M now. TM wanted to give you 4M and you plan to upgrade to 8M? 
I do not really know how to use OBS. Under 'Broadcast settings', try selecting 'Minimize network impact'
If this does not help, do try the software recommended by blacktubi, or you'd need to look for other software that is able to control network connections and uploads speeds for OBS.

Problem resolved!   Hoping it stays fixed.
Now my IP address shows on TM's speed test, unlike before.

Yes. My area support 8MB but I didn't know if my Attenuation is good for 8MB or not so I picked 4MB first .

wow nice..can u show us this thing?
and ur downloading speed for any file.

Hi guys,

i just receive my 4mbps package and port. (took 4 days for them to change my port)

But why am i assigned to

Downstream Line Rate (Kbps): 4094
Upstream Line Rate (Kbps):          509

As i though that was for 2mbps user?

User who subscribe 4mbps should get a port of 5mbps which is

Downstream Line Rate (Kbps): 5xxx
Upstream Line Rate (Kbps):          509

Isn't that correct?

Consistenly receiving 350kb/s to 390kb/s or 2.8mbps to 3.12mbps < Not even 80% best effort speed lol...

Line miscap.
Need to ask TM to adjust. Maybe call your installer.

Everything's alright ,no miscapped.
