asus rt ax82u

Hello, I have a RT-AX82U V1 with stock Firmware-Version:3.0.0.4.388_22525 It doesnt matter which merlin gnuton version I choose, its always says "failed Can anyone help me? kind regards

Anyone else seeing this on Verizon FIOS ? I am seeing a drop in upload speed since updating firmware. I am able to pass 900 in both directions through the router between two hardwired systems using iperf3 but not to the router. Running iPerf3 from LAN2 server (...34) to LAN4 client (...80)...

I did a test of the AX58U, AX82U, and AX86U. Out of the 3 I was most surprised at the AX86U results. It performed alright, but definitely not as good as the AX82U. Any ideas? The AX82U achieved 50 Mbps+ better than the AX86U. The AX86U should be better right? Thanks in advance!
