I just upgraded from 200 Mbps to 1000 Mbps internet but I'm stuck at 200Mbps while using GT-AC5300
If I connect my computer directly to modem I'm getting full speed(well, around 900Mbps) but when I connect to GT-AC5300 I'm getting exactly 200Mbps.

All LAN connections are 1Gbps(Modem to router and router to PC).
Resetting router to Factory default didn't help, still 200Mbps

Is there some settings I need to change? Or what can be the issue?

Given you use the same PC and same network port of that PC to connect to either the router or the modem:
I suspect the cable between the PC and the router.

And if it's not the cable, try a cheap and cheerful switch between the modem and the router. :)
