**Background** I am using Nicla Vision ([Nicla Vision - SEN-19728 - SparkFun Electronics](https://www.sparkfun.com/products/19728)) for image classification using the OpenMV Editor 4.2.4 and Edge Impulse. It works perfectly fine. However, I am having trouble with the wi-fi to connect to wifi networks. I have tried using the wi-fi connect example listed here: [https://docs.arduino.cc/tutorials/nicla-vision/live-streaming/](https://docs.arduino.cc/tutorials/nicla-vision/live-streaming/) and also the OpenMV IDE examples (File–\>Examples–\>WiFi) scan.py and connect.py that come along with the OpenMV IDE editor. **Problem** What I have noticed with scan.py is the following: - There are many wifi networks in my work area (more than 7-8) - The scan.py seems to pick up only a few networks. All the networks it seems to pick up have Auth = 5 or 7. It is not picking up any other networks. - From trial and error, I find that, it is picking up only networks that are on Wi-Fi 6 (802.11 ax) protocol. It is not picking up networks that are on Wi-Fi 4 (802.11n) protocol. In fact, even when the Nicla Vision is just one feet away from Wi-Fi 4 networks, it is not picking them up. I have the same observation with connect.py - connect.py connects only to networks that are on Wi-Fi 6 (802.11 ax) protocol and also have WPA2-Personal security type. - If I change the Wi-Fi protocol for a given network or if I change the security type (to say WPA3-Personal), connect.py does not connect to the network (even if the SSID and KEY are the same). Is this a known behavior for Nicla Vision? Or, am I missing something? ---

The Nicla doesn’t have an “802.11 ax” radio. It can only do b/g/n and will only work with WPA2 networks. I think something else may be going on in your environment. I have an Eero 6 router, and it works fine with my WiFi network. I have 5 access points in my house and it picks up all five at once. Channel 4 and Auth 5. Can you make sure b/g/n is turned on with your router? ---

I am using a Nokia G-140W-C router and confirm that b/g/n is turned on for two networks (one on 2.4GHz and another on 5GHz). In fact, I connect my laptop to both the networks and can see that they are on Wi-Fi 4 (b/g/n). It is strange that Nicla doesn’t have “802.11 ax” radio, but it is connecting to a hotspot that I have turned on from my Nothing 2a phone. That network is on Wi-Fi 6(802.11 ax). ---

I played around with my router settings and changing a setting’s value (setting “WPA Version” from “WPA/WPA2” to “WPA2”) did the trick. The Nicla Vision is now able to connect to a 2.4GHz network on Wi-fi 4 (b/g/n) with WP2-Personal encryption mode.
