Hello all! I recently tried installing FreeBSD 15.0-STABLE on a Lenovo
ThinkPad T490s with an Intel Corporation Cannon Point-LP CNVi WiFi card and
the installation medium was unable to connect to any networks which I tried
it on. Some were open, some required a passphrase, and one was an 'eduroam'
network. It proved unable to connect to any of these networks. I tried it
on three separate networks. It was successfully able to scan for the
networks, however, DHCP failed in all three cases. Sometimes I would
receive a message along the lines of "iwm0: Failed to initialize scan", and
other times I received messages saying from dhclient that the buffer had no
space followed by a message telling me that the network was down. I assume
that this is a problem related to the drivers for this device. Thank you
all for your time!!
