Hello, I ran into a rather strange problem, maybe someone knows the solution. I recently bought this router and noticed that it does not give out and close to the speed declared by the ISP. I have 1 Gbps internet, but the speed test on the ISP server shows 390-410 Mbps, while my previous router showed 900-950 Mbps. I also did tests with iperf3 between a PC and a laptop and got a speed of 700 mbps, that is, the problem is precisely in cutting down the speed of the WAN, I use a PPPoE connection
