Maybe u should list out ur Modem and Router model ?

I'll use "kawan" then, kinda feel like entering a secret society
Most probably router problem assuming you test this on LAN cable

I just finished dealing with this issue, I was on the 1gbps plan i was sneakily upgraded to the 2gbps plan. I found the upgrade email in my junk email as I autopay my connection.

My speed went from around 1gbps to 80-90mbps overnight. Took me 13 days of lodging tickets after tickets and issue not resolved. I lodged a complain with MCMC against TM and finally on the 15th day of extremely slow internet they sent someone over to fix my problem.

TM agents was absolutely useless in resolving the issue. Essentially my modem couldn't support 1mbps according to technician but he cannot do anything as the service order for him was to investigate the slow connection and not replace any boxes.

Same here. I get free upgrade from 500mbps to 800mbps but speed test result around 500mbps only.

Hi guys currently on 1gbps plan but the speed i received at my asus router is only 300mbps. Any idea whats wrong? Restarted and everything would like to solve it sendiri before reaching unifi.

Currently on Dlink DPN-FX3060V in bridge mode connected to Asus ZenWifi BQ16.
Test was done internally on my Asus ZenWifi BQ16. Was doing 1gbps without problems.

How about try to use MAC address clone at WAN setting of your Asus? My slow upload issue needs this setting to overcome whatever TM was messing around at their end.

If you're using the black color dlink, upgrade to firmware 2.0.6
