EX3110 – AC750 Dual Band WiFi Range Extender

Extenders cut the throughput speeds in half for what they receive. This happens because they have to use the same chip to go router----extender and then extender----device. And they can't do both at once. And thats based off the speed they recieve. So because of distance, obstructions, interference, etc, its extender is already going to be receiving a reduced speed from the router. 

So if you're base speed from the router is 150mbps and because of distance/obstructions/etc, the extender is only picking up 100mbps, its only going to be putting out 50mbps. 

So you're speeds might actually be fairly spot on. 

Its the whole reason for the triband line of extenders and mesh systems. They have a dedicated wireless backhaul for router----extender communication.
