What is the interior layout of your home? How many walls are there between where you want to put the router and where you need to use it? I used to work in Pulian, and the TP-LINK router produced by this company does not have much signal attenuation through the third layer, but if you buy a refurbished machine, you can't guarantee it.

Is it not good to buy a router, I bought it online, installed on the 3rd floor, and there are one or two bars of signal on the first floor.

It may be that your router's signal can't go through the wall! It is recommended to rebuy.
900M has nothing to do with the signal, 900M is the bandwidth. The wireless signal mainly depends on the structure of the wall and the number of passing through the wall, such as the density of the reinforcement of the load-bearing wall is high, and the signal shielding is more obvious.
If the distance is too far, the router may not have the ability to penetrate the wall, and there are steel bars and concrete inside the wall, which filters the signal, so it is very weak.
If the signal is too weak, or the walls are too thick, it is recommended that you open the bedroom door and try it, it should be better.
Twist the direction of that line on the router.
Because I don't understand how it works. In other words, it won't work yet. >>>More
