@Madhukar Do you use Smart Connect technology? If yes, that could be it, the repeater tends to automatically throw you into the 2.4GHz network even if you are close to it, but let it be clear that this repeater does not passes more than 100Mbps due to the port LAN being 100Mbps, so don't expect speeds above 100Mbps, but if you turn off the Smart Connect function, you already go up from 60Mbps to 100Mbps, it helps a lot.

@Andrsouzaaa 

Thanks for the detailed explanation.

I haven't enabled Smart Connect.

Moreover, based on my understanding, on Wireless it should allow upto 300Mbps in 2.4 GHz band, and upto 867 Mbps under 5GHz band.

I am not using the LAN Port, due to its limitation.

Lastly, is there a way I can bind one of my laptops which is stationed equidistant from both the main router and the extender to the main router?

Thanks in advance!

  @Madhukar well in the post you want more speed, try to find an outlet closer to the router and connect the RE there, and don't wait for it to exceed 100Mbps , I have it this RE305 , I have a RE200, I have a RE450 and a RE650 and I know when I say that the RE below the RE450 does not pass more than 100Mbps, it is like a router it can be an AC1200 but if the port is 10/100 it will only pass 100Mbps, now if the port is 10/100/1000 then yes it passes above 100Mbps. try to connect it closer, it will improve, but don't expect a miracle... these input repeaters are really weak.
