I set up an automated speedtest measurement and recording system, it runs every 15 minutes for 24/7 and has been running for the past 16 days so that works out to be over 1,500 tests.

This is what I see:


I'm subscribed to 500mbps package but I seem to be artificially limited to 300mbps most of the time. The spikes that you see when I get 500mbps are always because I either restarted my router or when TM resets my connection after I make a complaint. However, the graph shows that my speeds get reduced back down to 300mbps shortly after that - sometimes it could last 2 days, sometimes only a few hours.

I've made complaints to TM several times and every time they "reset my port", the speed goes back to normal and they declare that they solved my problem so there's no avenue for me to escalate further.

Is this the work of TM or is it caused by something else?

In my housing area, someone complained about loss of speed, and TM said 10 houses in my area were having the issue.

If TM tells me there is a widespread slowdown due to MCO or whatever I can still accept, but the data here suggests that it is a very specific situation where my bandwidth is capped after a while, and the remedy (reset port / restart router) is made to look like it has resolved the problem only for the cap to return when the case is closed.

your speedtest is local or international server?

99.5% local servers. Sometimes the automated server picks a server in Indonesia but only happened a few times.

Seems like qos , shaping. Need to check on the user and also isp. If you're enterprise customer, like company using mpls link can ask them the shaper config at their side. Besides checking your router.
As normal home user don't think so we can ask them... At least I never done.

i hv a feeling that my unifi service is like TS also but no evidence to backup
500mbps but now getting 90mbps

I'm sure I've disabled QoS on my end. I just want to rule out all possibilities that it is caused by anything on my end.

If you suddenly get good speeds after you restart your router, then it may be an indication that you're facing the same thing.

i believe they bottleneck over international speed at peak hours. but for local the connection to TIME or MYIX only sometime might caused by congestion traffic.

I don't quite believe this is caused by congestion though. Have a look at the graph, the variance is very small. It is either 500+/-mbps or 300+/-mbps with almost nothing in between. It has also never dropped below 300mbps either. It looks like an artificial cap.

yes, nearly every time after a reboot I get the speed that I paid for
past month or so only noted this

This is my SpeedTest History graph. ROuter never reboot in the last week or so.
I set it to always speed teset TM cyberjaya server. I noticed automatic speed test server selection sometime point to unreliable server.

Try to set your speed test to test nearest TM speedtest server.

What good if the 800mbps can only to local Speedtest servers?

I have logs that show the speedtests were performed using local servers and I can set a static server if I wanted to, but I feel there should be some randomness in choosing the servers.

If the connection cannot even maintain a consistent speed across a few local servers, then it is simply not reliable.

From the image ts shares, what I can see is short burst, allowed by shapers. It will allow to beyond cir for a while then reduce the rate to smoothen traffic. It's hard to check with tm since they won't provide. Noted that you mentioned you have checked qos. If Cisco router I can check the config if you attach here. Not other device though. Do you have another vendor router to test this?

tm wants to fool the foolish people who think they need more than 300mbps for home line cause most likely they do not know what theyre doing

try with unifi biz line and see what happens

I dont think TM got any speed throttling to local network.
Currently there is only multiple reason will causing slow speed.
1.Local area maintenance-this will having a few hours of very very slow speed like few or xx mbps only.
2.Local area congestion-If your area too many user using at the same time,it might get slower speed.
3.Slow speed to malaysia server at peak hour-This is happens every few days for 1-2hours when TM to local network having congestion issue which will causing high latency spikes and slower speed.

As for international server,TM never said they will provided stable connection to international server,so slower speed to worldwide server is quite normal.
Even to singapore,after adding 40G OVH SG private peering and 100G of SGIX,and TM to SG will still having problem every few days,so it is really TM problem...

Not under Unifi but i'm using maxis broadband(supposedly using same infrastructure as unifi?) but i am facing similar issues having average of around 250 mbps speeds when i have 500 mbps package. I do not have automated speedtests but randomly run a few each day and sometimes i go as low as 80-90. Speedtests are ran to both malaysia/singapore servers.

I have 800Mbps package but can only get that speed if I do a Safe mode boot. Otherwise, best around 500Mbps.
