Beaglebone Black Wireless, Wifi extremely slow

Hello Everyone,

I have succeed to configure the wifi on my BBB wireless, however the speed of this interface is ridiculously slow, 10kB/s doing apt update/upgrade and the ssh works really laggy. When I connect the device using the usb interface I don’t have this problems.

The current image that I am using is: bone-debian-9.4-lxqt-armhf-2018-06-17-4gb

I would be really thankful if anyone could provide some help about this.
