If we pay for an internet speed of 100 Mbps, what is the "normal" and acceptable speed should we get? and what if 1000 Mbps?

@Solla-topee Yes, I know that Archer C80 has gigabit ports and AC 1900,...but in terms of wireless signal strength, what's the use of gigabit ports if onemesh doesn't support ethernet backhaul? and...

@Solla-topee In terms of signal strength, which one is better Archer C80 + RE305 vs 2 pack Deco E4

We can only have one router in OneMesh system, but how many extenders can we have ideally?

@TP-Link I compared them here, Compare Product: Deco M4 (3-pack) vs Deco E4 (1-pack) (tp-link.com)

@TP-Link_Deco Yes, the only difference I see is Ethernet ports speed, so why M4 has a wifi range of 3-5 bedrooms while E4 has only 3-4 bedrooms? both are AC 1200, same antennas, beamforming etc
