You need this to play around with LAN cable. RJ45 header pin can can easily worn out if always plug & play.

I think he need a professional Fluke Network Cable Tester. The one that came with calibration certificate

I actually got this tester one. 
But i dont think all cable is broken,as the branded 2 only use a few time only. Ugreen one just taken from TV and AP.
Vention one just use for sometime testing.
Fluke too expensive cant lah...

And the quick update:
No seeing latency spikes so far with the old ONU. 
Whether i spam full upload or not.
With GN630V,as i only upload to google drive will show the latency spikes but of course not like 2days ago 800ms,but like 40ms yes.

Is it the time to call Anime4000 step in? 
But the only reason i still cant use his custom-made ONU,is because my family still need the dect phone to work...

I believe his ONU can force forward VLAN 400. Check with him.
Then use my method in his ONU stick thread to connect any Android phone.

Usually promo for port in is free 6 months or free TV. The process is seemless and no downtime at all.
Firstly, go to Tmpoint or any trusted unifi agent to register your plan. Tell them you want to port over from Celcom.
After registration, just wait for Celcom to approve your transfer request. Make sure you clear all outstanding bill. Once transfer is approved, just wait for TM to set installation date. Your Celcom fibre will continue to be usable until few days after Unifi installation.
On the day of installation, TM will just plug in Unifi router and configure your connection.
Remember that there will be a final prorated bill for your Celcom fibre.

1050M with new ONU is quite attractive leh...
If stick with old onu really not acceptable... (900M)

No need fluke, use cheap multimeter to test cable connectivity or diy buzzer. Human handling basically can make everything can't use.

Emm actually i dont mind to get a ATA adapter if this work with unifi and his ONU.
But i worry that upload latency spikes issue occurs again with his ONU,and in the end might wasting money...



Update:
What the hell,i dc again...

No wonder fail to ping.
You got alcohol swab pad? Go clean your fiber connector.

Got 70+% alcohol.

Good enough. Take out the SC connector and clean it. Hope it works. Like I really no idea what else to try already.
No need to be perfectionist. A lot of people only use the 70% pad to clean before slicing. All works.

Cleaned.
New IP range:
2001:e68:5432:cbcb::

It is quite an improvement!

Emm i didn't see any improvement on my end.

Next time i will just buy the fiber optic cleaner easier.

Swiss army tool for fiber optic.

Old:
rtt min/avg/max/mdev = 8.970/37.573/169.916/37.022 ms, ipg/ewma 200.632/27.331 ms
New:
rtt min/avg/max/mdev = 8.236/13.084/24.203/2.432 ms, pipe 2, ipg/ewma 13.084/12.841 ms

No improvement meh?
If you have a lot of connector to clean then it is better to use the clicker. But you buy to clean one connector then kind of waste? Of course you can clean inside the ONU port with the clicker.

If still dc... I think better you report to TM and see if they want to clean their fiber splitter or even willing to swap their line card.

Cleaner price okay lah,and clean ONU port might be needed since i keep swap for few times already confirm got dust already.
You see in DC already clean,and they still got alot of port not working when early started..hahaha 

Sorry for tagging you hsbb
Which mm should i buy for cleaning this unifi SC fiber optic.
1.25mm or 2.5mm?

Ah i know already sorry for tagging. 2.5mm is use for SC.
SSHHHITTTT DC again.

Yes it is 2.5.
Okay, time to file report already. Unless you remotely consider the possibility of needing to RMA your Mikrotik.

Ethernet port not down,also have the possibility for mikrotik broken? 

Let me observe until tomorrow afternoon.
Incase they really doing the maintenance.

Report is quite trouble...Later tm said not their fault and charge RM53...
