Router slowing down internet speed

[petarbg]

Hello, please help. 

I have an RT-AC88U router. I've found that it is reducing my internet speed. The maximum I am getting on the speed test is 94 Mbs but my ISP is providing 400Mbs.

ISP modem is plugged into RT-AC88U and it worked fine for years until recently. As soon as I directly connect ISP router, everything is fine with the speade which leaves ASUS router as a problem.

I've tried different cables, all LAN ports and also factory reset, and various firmware updates but there is no change.

Please help.

The problem is a faulty WAN port on the ASUS router. The solution is to enable dual WAN and then use LAN port as WAN. Now it is fine but I will never buy an Asus device again.
