I have successfully configured TP-LINK WR740N as a repeater as instructed in this thread as well as on the official tp-link site. Root router is same model.
However, when I did that, although I get better range the speed drops in half, or less. At the same spot, if I connect to the root router I would get 60-70Mbps, while when I connect to the repeater I am getting 25-30 Mbps at best.
Any idea why this is happening, can it be fixed or is it expected?
