Hi

I have bought a Wifi Extender  ( AC 1200 ) 

The installation was ok

But after i have made a speed test 

First connected to my internet Box routeur and here is the result

And here below the test made when connected tp  the TPlink Repeater wifi   ( precision : The tplink was on the same room as the box router for the test )

Could anyone tell me why this difference ?

It's seems that if those results are correct the tplink couldn't be useful for me at home

Thanks for your help
