• wifi protocol 802.11b?

• QoS rate limit set too low?

wifi protocol is AC - at least that is what my Mac says.

QoS is not enabled - do I enable it and what settings should I put?

Yes, check the wifi speed on ur phone, and is it 80 MHz or not.
Then change ur 5GHz channel la.

or since you're on your mac, open up wireless diagnotics app, ignore the main window, and open "scan" from window menu


and you'll see the least debauched channels for your home


that is, if you've not already done this

Did you get public IP address with this?

Some further update:
TM suddenly called and said the DLink router is available. Proceeded to replace both my Fiberhome with DLink AX3000. The model is X3060Z (black colour with 5 antennas).

So far, managed to set up everything properly. The only downside is one of the ports is reserved for IPTV and despite all my tinkering it couldn't be "released" as a normal Ethernet port.

Hence, got a TP Link T3U AC1300 USB card, so far tested can get 500Mbps on the link after driver update.

Seems everything is working so far. One main router, one Bridge mode with wired LAN.

The DLink is definitely much easier to set up and works almost out of the box.

Hope it continues to be smooth and steady.

EDIT: linking another forumer's post that helped me set up the DLink. He has the same model as I do.

Yes, but like some other forumers mentioned, by default you can't choose.

I think in my case, there were 2 things that worked in my favor:
1. The salesperson promised me the Dlink
2. There was an exact model (but with some red stripes) in the Unifi Centre itself, with the price tag of FREE if you sign up 100Mbps and above.

They were very reluctant to entertain me, and I pretty much gave up already. Didn't really pursue it after a few calls and follow up.

Then suddenly, they called so I just agreed to it.

I am on SWU 3.0 500Mbps.

My account details changed to SWU 3.0
But what does M6 means?

i switch to maxis today. RM129 for 300mbps
sick of their super far route

That's SWU 4.0, urs should be 3.0
