I have been using this Tenda M3 wifi router in my home for my optical fiber internet connection since may 2015 and I am totally satisfied with it.
Tenda M3 looks nice, very light, and tiny size.Signal strength is very good in our small house.
It has one RJ-45 WAN input port, one RJ-45 LAN output port and a tilt-able wifi antenna.It works on 12v AC DC adapter.It is not a modem just a wifi router only.We have two laptops and two phones in our house and I am able to connect these four simultaneously to the wifi router.In that case, the internet speed gets equally divided. The wifi UI can be accessed at 192.168.0.1 on your chrome or firefox .The UI is clean, simple and easy to configure .It has facilities like password setting, traffic monitor, bandwidth limiting for a particular connected device and MAC address blocking.
IMPORTANT NOTE;
If you have a very big house or have two-story house, this router may not show good signal strengths as it is entry level model and the cheapest Tenda in market.
