OMG that is scary and diabolical man!

Both my dlinks at different sites have this problem, suddenly speed with throttle down to 300/100. white and black also like that. There seems to be no set schedule when it happens, sometimes, day time, night time/ twice a day, 3 days once......

Black one will replace once i get my media converter, will use with the ODI stick.

I tried changing all sorts of setting, no point mentioning coz nothing worked.

Since it's a 1 gbps package, I have reverted to to the old huawei onu, it's been two days, speed hasnt' dropped yet. Will wait 1 week and update here (Coz sometimes the speed can tahan 4, 5 days, then suddenly drop again).

My other site is using a 2 gbps package, so using the old onu is not an option. For this site, I'm using an SFP xpon flashed by Anime4000.

Basically, stopped using the dlink ONU's both white and black.

It's has been 1 week, speeds are stable on both sides, one using old ONU, other using the Xpon stick.

This pretty much confirms that the speed throttling issue is only with the black or white D-Link ONR, using bridge mode
