I can easily connect from win7 or win10, so I know it isn't a hardware problem. My usual puppy (friendly-fossa64-rc3) has no problem with open wifi connections, but can't handle the wpa2-psk iphone wifi. It detects the network, intermittently, but any attempt to connect or scan the network results in no network found.
I recently saw in another thread that slackpup is the most recent puppy available, so I downloadeed S15Pup64-22.12+2-T and tried that, with the same results.
If anyone has actually gotten a puppy to connect to a current IOS hotspot, I'd like to hear how you did it. If no one actually has done that, I'll move on to trying mint linux.
