how can I boost the signal strength of an AT&T WiFi extender?

Last Modified: 2020-03-10
Hello and Good Afternoon Everyone,

          Recently, I purchased an AT&T WiFi extender that broadcasts on both, 2.4GHz and 5 GHz frequencies in order to secure a wireless connection on the other side of the house so my friend can access the internet.   While he is able to load web pages and playback videos on YouTube, the signal strength is very low, about 1 to 2 bars.  My concern is that the low signal strength will eventually drop off to nothing, thus, leaving my friend without any internet access.  Given this situation, what would everyone recommend with respect to boosting or increasing the wireless signal strength?  Will another WiFi extender be in order to place on the other side of the wall where my friend lives?

           Any feedback that can be given here will be greatly appreciated.

          Thank you
