OK, so there are a lot of posts from people struggling to connect their NANO 33 to a WiFi network. I have read most of the other related posts, but they appear to be having issues further along... I can't even find a network to connect to.
My problem is that my board fails to even find a network.. I ended up using the example ScanNetworks sketch to try to diagnose why the board fails to connect to my SSID.
So, working through the sketch, everything seems to be OK, We pass the tests for module status and latest firmware; the MAC is detected and printed out in the serial monitor.
But when the program gets to the ListNetworks() function it appears to hang at the point it calls the WiFiNINA lib with int numSsid = WiFi.scanNetworks();
I inserted Serial.println(numSsid); directly after the call to check what was being returned. But nothing appears in the serial monitor after "** Scan Networks **" is displayed, so I suspect that the sketch is stuck in the call to WiFiNINA.
I have updated the library to 1.8.14 and the board firmware to 1.50 but the board seems to be unable to detect/connect to WiFi......
2.4 GHz. Just a standard N type WiFi router I believe? I have no problems connecting to it with various RPI models. My phone says 40MHz, WPA2/WPA(AES/TKIP)
I just wanted to point out that some devices do NOT work with 5G and greater devices. You should be ok. I think I have a NANO 33 in my collection, let me try a wifi scan, I have a few dozen or hundreds of SSID's here. BRB
Update the board's wifininna firmware following Use the Firmware Updater in Arduino IDE and then create a 2.4Ghz Wifi (you can create a simple hotspot with your phone to test. This will allow you to rule out router issue or board's connectivity radio hardware fault) and connect to it.
