Hello, I have a D-Link N300 (Realtek RTL8196E) that I connect to a pynq-z1. I tried with images 2.4 and 2.5. The wifi dongle is recognized as I can see it with `lsusb`, however, when I want to connect to my network, I always get the following. ```auto xilinx@pynq:~/pynq$ sudo python3 Python 3.6.5 (default, Apr 1 2018, 05:46:30) [GCC 7.3.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> from lib import Wifi >>> port = Wifi() >>> port.connect('MYSSID','PASSWORD') ifdown: interface wlan0 not configured Internet Systems Consortium DHCP Client 4.3.5 Copyright 2004-2016 Internet Systems Consortium.

No working leases in persistent database - sleeping. ``` I tried even on different networks, with a router and using two mobile phones as hotspots. The problem remains. I even read that I should use a Logilink WL0084E (Realtek RTL8188EUS) but that is not even recognized when plugged. Anyone knows what could be the problem?
