hi, if i'm cancel my time i need to pay 2month advance? why?

i suggest u download wifiman (assuming u use android) onto smartphone. then check ur wifi signal dbm. just because ur speed is good in one area, doesnt mean its the same in another. so try walk around and see ur results (both signal and the local speed test)

then also run openspeedtest self hosted
https://github.com/openspeedtest/Speed-Test
this can check whether ur wifi has any issues or not.
u say inconsistent. i would first suspect wifi signal not good, too much interference? or simply ur wifi thoroughput using that wifi ap is bad but u did not realize. Check that first.

Once u rule that out, then ok then check other things 
or u can skip all that and go straight to wired and see its improved or not. id still want to check wifi is not the issue if i were u since its something i actually use 

i am testing in front of the main wifi router, previously i can get full speed, and now sometimes i can get full speed but not all the time.

suspect it is the bandwidth that is shared by too many residents during peak hours, so cannot hit the max speed.

wifi 5 has much higher bandwidth, and i dun believe, it is due to the wifi router issue as i can hit the max speed with no prob with the wifi 5 mesh router (tri-band) somemore.

Just buy your own router and buy something high end that's at least RM400 or more

Cheap routers cant handle busy network conditions at high density condo

This is actually helpful - do you have a recommendation for me? It would have to be a GPON router right?

Very poor and very inconsistent speed nowadays.
600Mbps plan here.

Speed test done at 12pm on a Sunday

i using time for 7 years they say if i need terminate i need return my onu and my old router... the problem is i dont know where i keep the router.... so buy 1 at from other people and keep?

Only TM asked to return the terminal to TM Point/Click (or some other names). Maybe just to trouble the users so they reluctant to terminate.

I didn’t have to. Transferred to Maxis. TM came and just changed ONT with different logo. Unifi logo to TM logo. Then just left the Unifi logo one with me. After terminate Maxis, didn’t have to return also. I guess depends

now celcom also offers fibre broadband using time broadband's infra? becos i can see that the apartment i am staying is under the coverage now... and also saw celcom offers promo package to another apartment (collected keys last year) very attractive package for new sign up also.

Celcom using TIME for a while now. Celcom CGNAT is very bad. Lots of site limit their IP and causes issue.

Does TIME offer any discount for contract renewal? Or they only counter offer when we port out?
