might found the cause of lag,but no fix yet

Straight to the point, this post is only for those who can access their fiber-modem. You need to unplug the fiber that goes into your
fiber-modem that helps me eliminate the lag.
This may sound counter-intuitive, since fiber network is known to be emi-free.
However, it's not the case in my scenario,
1. the fiber comes into my home contains conductive metal for improving its cable tenacity
2. the process of transforming from light signal to electrical signal causes huge emi

So my theory is the either the fiber cable or the fiber modem is the source of the lag.
I did the experiment long time ago:
1. unplug fiber cable from the modem, no lag
2. unplug everything from the modem (ethernet cable and power adapter) except the fiber cable, no lag
3. every other combination will cause lag

I used to play cs1.6 very competitively, so there is no doubt that I know how the right feeling of mouse movement it should be. I no longer play FPS competitively, so actually I don't care about whether it could be fixed or not. So I only conduct the experiment above for a short period of time. And I have no obligation for answering or debating. Just throw out a possible cause, after seeing a recent post that blaming FTTH might be the cause. I am tired of all these, but still happy to see it can be solved in my life time. Please share your test results and possible fix on this. GL to you all

Did you tried WiFi? or maybe another Router, i only have company router and feel same problem you describe, unplugging ethernet from computer, after hours start working good.

IMO wifi will only work under strict condition, dc battery or ups as the power supply of your modem, and no ethernet connection, otherwise the interference caused by fiber will polutte the whole electricity in ur home through power adapter. It's nothing wrong with the router, the thing goes wrong is my fiber-modem, that's two different thing.

Every change is temporary. unplugging ethernet will temporarily fix your issue. it may take weeks/days for the problem to come back while keeping ethernet unplugged.
