We are having some issues while attempting to connect via WiFi to the Pi Image on a Printer.
We have tested with more than 20 laptops without success, and with more than 15 phones, and only one phone worked.
We tried the language trick, modify the hostname, ssid, password, channel, region, on/off the RPi but can't manage any laptop to connect to the wifi.
the error on windows PC is "cant connect to network", some phones weirdly suggest "password might be wrong"
windows versions tested, windows 10, 8.1 and 7.
phone, android and ios versions varies.
the only one phone able to connect was an android 8.0
we have tried the usual troubleshooting reset the network adapter, turn it on/off, forget the network, but we don't think that the issue is withing the computers....
anyone having this issue? how you guys solve it?
