I have both the GL-M2 (with RM520GL) and GL-AX3000-5G.
My GL-AX3000-5G usually gets >300 Mbps while GL-M2 tops out at around 2xx Mbps on the same bands/towers. Is there a max supported speed for GL-M2?
I have the GL-M2 connected (via USB3) to GL-AXT1800. Is the USB3 port slowing things down? The USB3 cable is about 1ft or 0.3m.
