TL-WA854RE300Mbps Universal WiFi Range Extender User Guide
T4. How can I know that my wireless signal has been repeated and boosted by TL-WA854RE?
An easy way is to compare the signal strength of your target wireless network (symbolized by its SSID), with TL-WA854RE in operation vs. out of operation. Before comparison, you’d better make sure your computer can obtain an IP address from your target wireless network and thus access the Internet, either via TL-WA854RE or without.
T5. Why does the wireless transmission rate speed down, while the wireless signal is stronger after repeated by TL-WA854RE?
In compliance with the wireless transmission protocol, all the Range Extender devices are set to work in half-duplex instead of full-duplex mode. In other words, the Range 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 Range Extender when your home network connection is poor, or when you want a larger wireless coverage to eliminate “dead zones”.
