Could be many things. WiFi seems to offer woefully inadequate

My understanding that is compiled modules are not portable across
kernels. There may be qualifiers on that, such as it'll work, as long as
the ABI hasn't changed.

Assuming there aren't alternate driver packages that work with your
interface, I'd seek out the upstream project responsible for the driver,
see if there is a newer version, and compile it for your current kernel.
