I purchased a RT AX58U and flashed with Merlin as I did my AX88U. Running Surfshark on the AX58U I am in the 40 Mbps range vs over 100 Mbps on the AX88U. I read the AX88U processor is why. So in light of simple and slow AX58U I will be reverting back to the AX88U. Did not realize this fact. Wasted money.
