First off I will say I am pretty good at computers.. Not a professional but better than most people. The set-up instructions look easy and have nice pictures to go along with the directions. I used option 1 and everything was going fine, but I was impatient and hit my refresh button and everything messed up. I wasn't allowed to get back on the tp-link setup website without a password at first, but then it let me when I tried the next day. It was frustrating, but it worked out in the end and was probably my own fault. We live on the top of a hill and our internet wifi connection is usually about 3 out of 5 bars. Once the tp-link extender was connected through option 1 I was able to move it further away from the router in order to extend our existing service. This really helped our signal! Now we usually have 4 bars and also 3 bars in areas where signal was normally poor. We have a large house and we live in an acre of land. This allowed our wifi to work outside the house and further out than it ever had. I was really pleased because so many things run on wifi these days, like our baby monitor! I used to have the problem of the monitor saying no signal when I was in the laundry room, but now no more! This was exactly what we needed. It's allowed us to be anywhere in our house and have a normal signal, no more weak signals. Also when you relocate your extender there are helpful lights on the front to let you know what distance will provide a good signal. This seems like a quality product so far!
