I planned everything for my house,but still got something out of that plan.I didn’t set any network port in the guest room where the WIFI signal is dramatically weak.Thus,I have to find out a way to let the room get the coverage of Internet service.Well,finally I opted powerline homeplug as my best option.
I bought a couple of TP Link PA201 Homeplug in the evening.

One is plugged near the router because it should get linked with it.Another one is just beside my computer.

The homeplug could run up to 200Mbps,but I only can get around 80Mbps with a straight distance of approx. 10 meter.That’s awesome!It’s even faster than WIFI b/g network running at the full speed.
TP Link is offering one to one exchange if the product has any problems in 2 years.It’s so convenient.However,I still hope that it won’t go spoiled in 2 years. ![]()
