What router? VDSL or Fibre? Ping to where?

Hi guys, appreciate some advice if possible. Here's the situation;

1) Upgraded to 30MB unifi but rarely get 20mb. Mostly 10-15mb only on wifi.
2) Staying in small apartment (850sqf). Router is located in living room while my room is just behind the living room wall - I dont close my door at all.
3) My router sometimes restart by itself and sometimes internet connection is very slow (talking bout dload speed of 100kpbs) - I have to restart my modem/router to solve this on daily basis.
4) Called unifi technical team and they attend twice but problem recurring again after few days. One of the technician advise me to get a better router as the set that I'm using is more than 3 years old already.

My question is, what should I get to a good 30mb connection in my room? I'm using a pc with a tp-link wifi adapter connected to it in my room.

Been reading a few post and few member mentioned about Asus RT-n66u as a router replacement. Is this a good solution? My budget is around Rm700-Rm1000 to fix this issue if possible.

Many thanks in advance.

Is there any benefit setting up unifi to use ipv6 instead of ipv4?

based on what is not good?
dont simply tembak say VDSL not good.
my condo also using VDSL dint see any disconnection and so on.

Yup, IPv4 is basically run out in Asia Pacific.

And you should enable IPv6 on your network if available (in the case of TM, yes)

However, unless you have issues accessing IPv6 enabled networks such as Facebook & Google, you should just use it. I don't have any issues with it unlike some forumers have that.

In that case, then you may want to disable it as suggested.

So far no problem for me, been watching 4k youtube video all the time. Issue been persisting even you restarted the BTU and Router?

Unifi also ma....
