Just installed LXLE (Linux) on several old laptops. This seems to be the best distro for just install and go. Quite fast. No broadcom wireless setup! Connection is just like any modern device. Includes some great utilities. The only downside is Claws mail! but that can be replaced with Thunderbird.
"Thank you for an amazingly GREAT distro. Been distro hopping for a while and you have come up with a beautiful, fully loaded, easy to use, sleek, fast distro that works great on old AND new hardware." ~tdlam
