The C9 is definitely better. Try updating the C9 firmware if possible, and see if that helps with getting full speed, even on 5GHz. Go to the official TP-Link product page here: https://www.tp-link.com/my/download/Archer-C9.html

Remember to check the router version and get the correct firmware for your router's version.

That router can't support 500Mbps over wifi. It can only support it via wired connection, with RJ45 Cat 5e and above. I suggest referring to 1st page, 1st post, green text, for a quick lesson in home networking, and recommendations for a good router for your speed.

I meant it cant support the speed over WiFi. It will be able to if it is wired connection. I am assuming you are connected to the router directly via RJ45 Cat 5e or above?

Just call TM to replace it for you for free.

Yes. Try asking them about it. They will probably tell you it will be before July,

Time to change router.

You can't change it yourself. Just call TM to come change it. It is free.

Just call TM for a change.
Nice. What device?

Good one. I am quite surprised but you must be near the router?

Good job

Buy new router, and get something good with a decent budget.

Sure la. They only provide a router that can support the speed on wired, but definitely not on WiFi. TM only promise that you can get the speed on wired, and NOT WiFi. You have to get your own router for that.

It is possible to reach the speed in WiFi, but you need to be near the router la. Nothing to do with new or old. If your device support 5GHz, then you will be able to connect on 5GHz. If not, then no. Older devices and cheap newer devices only support 2.4GHz. There is 5GHz N and 5GHz AC. You would want to connect to 5GHz AC, not 5GHz N.

Refer to 1st page, 1st post, green text, for a brief lesson in home networking.

Disable IPv6.

I suggest call installer to come check. It is definitely a physical issue. They need to check for you. Where in Penang are you? They could be doing some maintenance.

Lol. You don’t need to quote the whole first post. I did say 20MHz, somewhere in there: “2.4 GHz offers coverage for further distances, but may perform at slower speeds. Use 20MHz channels in the 2.4 GHz band”.

The bandwidth on 5GHz is up to you. You can go for 40MHz or 80MHz, depending on your devices and your speed.

Yes. Up to you.

Just keep bugging them or go personally to a TMPoint to complain.

You need devices that can support AX as well.

Read 1st page, 1st post, green text, as well.

Disable IPv6, and call TM if that doesn't work.

Both sound like router issue. Test with another router.

Turbo is pointless if you don't have a good router and devices that can support the speed, so don't get too depressed about it.

It will be until July 2019, as some have said, so you might need to wait. Are you even eligible for 300Mbps? If you can't wait, better to go for the new plans which is 100Mbps.

Up to you. You can, but won't make a difference.

Just get a new router. You will be happier if you did.

True. There are budget options though, so you can consider them. Just giving a suggestion
