The device will get a stronger wireless signal when it’s at the same altitude
as the router.
Note: The smaller negative number is better performance, eg, the Signal
Strength -32 will be better than the Signal Strength -50.
Tip 3. Pay attention to your wireless router’s antennas
As we know, our antenna signals are radiated vertically and outward. If you
only need to use it on the first floor of your home, we recommend you place
antennas vertically, so that the antenna coverage can achieve the best on
the same level.
