Unable to connect to WPA2 Enterprise network.

[ktbaker]

My Arduino Uno Wifi Rev2 won't connect to my university's WPA2 Enterprise network. I'm using the library's beginEnterprise() function. My sketch is based on the examples from the library.

The authentication of the network is PEAP/MSCHAPV2.

I've updated the firmware on my board to the latest version.

My board connects to regular networks using the function begin() so it's also not a hardware issue.

When I run the "ScanNetworks" example, the network I'm trying to connect to is listed, and it shows its encryption as "Unknown".

Additional context

I tried powering the board with an external power source.

I tried many different credentials.

@sandeepmistry Any thoughts? I see you created the WPA2 Enterprise support.

Hi Katie,
I'm a bit bothered by the Unknown encryption on scan. How does the network show up on a laptop / smartphone? We tested extensively on eduroam network but in that case the encryption field is always Open

Hi, I'm a little confused by your question. On my laptop and smartphone the network shows up just like how any other network shows up? In testing, I was trying to connect to eduroam network as well and its' encryption was also unknown.

[facchinm]

Sorry for the not so clear question, I was referring to something like this.

Is the board working in the eduroam network you tested?

[ktbaker]

I am on Apple devices so this information is not available but the security is 802.1x PEAP as per the university's website. The board does not connect to eduroam network.

Used my smartphone on my universities eduroam, it returns WPA2/WPA3-Enterprise security. my nano-33 IOT cannot connect. Scanninng wifi returns unknown encryption.

Hi, I also have the problem with Arduino MKR WiFi 1010 (NINA Firmware 1.4.8) and connecting to WPA2 Enterprise network.
The following example code just runs forever. I can successfully gain access to the network using Apple and Android phone or Windows 10 PC. I am happy to provide some more info If that would help...

while (status != WL_CONNECTED) {
    Serial.print("Connecting to network: ");
    Serial.println(ssid);
    status = WiFi.beginEnterprise(ssid, user, pass);
    delay(10000);
}

I am having the exact same issue, and both the ScanNetworks.ino and ScanNetworksAdvanced.ino code also give encryption types of "Unknown" for eduroam, and "None" for all non-enterprise networks. I wanted to add, however, that on both the ScanNetwork example code files, which can be seen here for example, there is a comment which says:

/*
 This example prints the board's MAC address, and
 scans for available WiFi networks using the NINA module.
 Every ten seconds, it scans again. It doesn't actually
 connect to any network, so no encryption scheme is specified.
...
*/

This seems to imply that no encryption will be given for any networks as the chip does not actually attempt to connect to any of them.

Has anyone found any solutions to this problem? My Arduino Uno Wifi Rev2 connects just fine on my home WiFi, but I would like to have it connect to my University WiFi as well.

Did you figure it out? My university told me that "Connecting requires the device to support WPA2-Enterprise encryption for security reasons." I'm using a nano Iot and the network scan shows my WifI but the encryption as unknown.

I was not able to figure out how to get my Uno WiFi Rev2 to connect to any WPA2-Enterprise networks.

I can potentially offer a small bit of advice, though. I thought I couldn't connect to my iPhone's hotspot because it failed when I typed out the SSID by hand.

The issue, for me, was that my iPhone was using ASCII to represent all but one character, the apostrophe, which was being represented by three bytes in who knows what kind of Unicode.

To solve this, I ran a modified example scan sketch, which would check if a network had a substring of my name, then wrote that string to my device's EEPROM with EEPROM.h. Then I could connect anytime by reading that string from the on-board ROM.

I used these functions.

Thank you CJacob314,
I actually spent a couple of hours trying to figure it out why it even doesn't connect to my iPhone's hot spot, and this was very helpful. I don't have any coding experience to do what you suggested because I'm a newbie to this. I changed my phone's name without any special characters and Whola! it connected to the hot spot :-)

Everything works fine on my home Wifi, but I still need to figure out a way to connect to my university Wifi because this is being built to be used in a greenhouse, for an automatic data logger from a couple of sensors and I'm trying to water my plants automatically. It's a complex watering and maintaining moisture levels and I'm spending three hours every other day doing this, which I feel like a waste of time. I'm not sure if nano Iot supports the encryption level that my university's wifi requires. Maybe I will need to find a better board that supports it if this doesn't work. I can't afford a wireless modem with crazy data monthly premiums.

Anyways, thank you for the help, really appreciate it.
