Does the GIGA support WiFi Auto and WPA3?
My GIGA sketch can access most WiFi networks OK using WPA2. I try using WPA2 first and then try twice more with Unspecified encryption.
But it's failing on an Xfinity WiFi network. The GIGA's WiFi library says the failing network's encryption is Auto, vs WPA2 from the networks that work OK.
BTW My iPhone can join that network just fine. Obviously I've triple checked that I'm using the right SSID and Password
Google says WiFi Auto may be referring to WiFi WPA3 encryption.
Any ideas what's going on and what it takes to join that network?
Hi Joe. mbed os supports WPA3 but the GIGA uses the Murata® 1DX module. This post confirms the module is nearing end-of-life and doesn't support WPA3. https://community.murata.com/s/question/0D5RC00000lh7OM0AY/1dx-wpa3-support
I'd raise a case with Arduino support and ask if future versions of the GIGA will be updated to use the newer Type 1YN module.
update: just switched the 2.4 band of my home router to WPA3-personal. My old phone couldn't see the network but my GIGAs connected! I specify the SSID and password in the WiFi.begin() call but don't specify the security (defaults to ENC_TYPE_UNKNOWN) so a network scan is done and must be finding it. The plot thickens.
update: scratch that latest update, my router needed power cycle before changes fully applied. Now can't get my GIGAs back on the 2.4 net with WPA2 - but that's my problem 
Lack of support for WPA3 also confirmed by page 7 of chipset ds https://www.infineon.com/dgdl/Infineon-CYW4334WKUBGT-DataSheet-v11_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0ee1f02f680f

Thanks for all of the great info and even doing first hand testing. I'm traveling and encountered this apparent WPA3 WiFi network. I'll have to do more thorough testing when I get back home.
For others: Be alert for AI hallucinations.
" Yes, the Arduino GIGA R1 WiFi board supports WPA3. It's based on the STM32H747XI microcontroller which supports WPA3-Personal and Protected Management Frames. The GIGA's WiFi library can also identify and connect to networks using WPA3, although the specific steps for configuring it may require some experimentation."
EDIT: This info first appeared to be an AI hallucination but might actually be possible....

Well the plot thickens further... Murata (WiFi module vendor) tech support was able to get this info from Infineon (WiFi chip vendor)...
Infineon has confirmed the following:
WPA3 is supported on 1DX. You can use wpa supplicant to connect to WPA3 AP.
So now I'm back to my original thought about what it would take to have the GIGA support WPA3. My first guess is maybe there's a newer version of the WiFi firmware that can be loaded into the WiFi QSPI FLASH partition.

Now I'm wondering if comes down to simply using the right security mode when connecting???
These modes are listed in the MBED docs as results after doing a Scan, but they're also mentioned as choices when connecting. Not sure which modes work on which platforms yet.
NSAPI_SECURITY_WPA2 phrase conforms to WPA2
NSAPI_SECURITY_WPA3 phrase conforms to WPA3
NSAPI_SECURITY_WPA3_WPA2 phrase conforms to WPA3_WPA2
NSAPI_SECURITY_UNKNOWN unknown/unsupported security in scan results
