What other details do you have on the wifi device? Could you post
chipset details of lspci output, or if usb, lsusb?

Usually with the newer kernels they are adding drivers, not removing
them, so unless Precise was using a wrapper with additional
configuration or you installed some funky firmware to establish wifi
connectivity previously, it should work.

My bet is some firmware didn't get installed on your latest installs
and it's likely a Broadcom wifi card since you mentioned an older
laptop and are using some older kernel versions. If so, I'd look into
getting the appropriate firmware to supplement the kernel drivers.

Not an Ubuntu guy outside of the servers, but they probably have a gui
you can search for firmware in. Isn't there one for drivers too?
Assuming you can plug into Ethernet I suppose... Or use a thumb drive
to transfer necessary packages over to the new install and use dpkg.
