PYNQ: PYTHON PRODUCTIVITY

Pynq-z2 cannot connect to internet through USB wifi

Hi, I am trying to connect my pynq z2 board to internet using USB wifi dongle (D-link DWA-31).
I tried using the wifi notebook already presented on pynq.

By using the terminal , I got the below result

By using python and trying the same commands as in notebook:

Please Help…

What type of WiFi network are you connecting to? It looks like you aren’t connecting or getting a DHCP address. This isn’t really a PYNQ issue. You may be better searching/posting on Linux forums.

For info, if you ut your SD card into your PC and open it you will see a boot.py file.

You can uncomment the appropriate lines and add SSID and password:

I am connecting to my phone’s hotspot. Also, not able to connect to any other wifi.
Is it possible that this D-link wifi dongle is not supported (As discussed here: RALink WiFi dongle with PYNQ/pynq/notebooks/common/wifi.ipynb - #10 by jbattat)

I tried that but pynq didnot completely boot then (I think it got stuck while connecting to the wifi).

Searched everywhere but no luck…

Can you share the output of?

OK, I think that means the WiFi device is recognised, so I think this is a Linux issue. Did you try search for anything related to this?
wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000

I don’t think you stated which version of PYNQ you are using. If you are using v2.6 it may be OK, but I would suggest you try the latest PYNQ image (v2.7 released recently).
