T6. Will the extender work if I connect its ETHERNET port to the router via
Ethernet cable?
Sorry, it won't work. The extender is designed to connect wirelessly to the
router, while the ETHERNET port is designed to connect with a wired
device, like Internet TV, Gaming console, DVR and so on.
T7. Why does the wireless transmission rate speed down, while the wireless
signal is stronger after repeated by the extender?
In compliance with the wireless transmission protocol, all the extender
devices are set to work in half-duplex instead of full-duplex mode. In other
words, the extender has to process one-way communication between your
root Wireless router (or AP) and the terminal clients; so the transmission
time will be double-increased, while the speed will be decreased. TP-LINK
recommends that you connect to the extender when your home network
connection is poor, or when you want a larger wireless coverage to
eliminate "dead zones".
