Hello, sorry to hear that the router performance is not as good as expected, while we can try to figure it out, we hope you could help verify some details:
1. May I know who is your ISP?
2. Are you connected to the 5GHz network when you experience the slow speed issue? How about the 2.4GHz connection, will it be normal?
3. Please tell me the wireless link speed at that time, how to get that? You can refer to the below link.

4. Ensure the QoS settings on the C9 is disabled.

@AndriusVs 

Hello again, here comes more deep problem, suddenly router gives me only 95 mbps, i did restart and again goes 850 mbps and after 15 minits again got 95mbps. I'm so depresed with these routers, Dlink, Belkin and now Tplink all made from trash .

 

Ok i have 3pc on Lan; 1 pc speed test 850mbps, 2 pc speed test about 600-500 mbps, but suddenly all pc gives 95 mbps result. I will need disconect this "super" router and test Dlink that i have in previuos, because speed is most important. And i think this Archer 1900 c9 have bugs from beginning of using, i dont know how your testing bureau is working, but in fact it has done bad or isn't tested at all, what is very popular these days.

 

Give me some clue people .

My best solution - take this router back and sell me one that is more expensive and tested and working good.
