Quote:
Although firmware can be ported from one Puppy to another, drivers have to be compiled against the kernel of the operating system.
If I may add, Mikeslr: this is not always true. The wifi drivers intel delivers are just executables/blobs(?) you have to put in /lib/firmware. No compiling in that case, but the version has to be right.
Problem in Puppy is often that the version of the blob is not right for the kernel of the Puppy. It is not easy to know what version(s) of the driver are right if you do not have the graphic card to try.
Also mind that some wifi cards do not work for older kernels. You can find that info on the site of the card maker (often intel).
On the intel sites I often cannot find the right version: intel often just gives one version of the driver, often an old one. But in the repos of debian and ubuntu all the versions are collected.


In fact, gyro on Puppy also keeps a great collection of firmware drivers: http://murga-linux.com/puppy/viewtopic.php?t=97276
If that does not work, you may have to compile! Rolling Eyes

You are confusing drivers with firmware. Intel provides an open-source wifi driver that is part of the standard kernel. Run:
Code:
modinfo iwlwifi

But the driver ALSO requires firmware which changes with each new model of Intel's wifi adapter. See the "firmware" list from the previous command.

If the required firmware is not included in the Puppy ISO, you need to install it separately.

Thanks for pointing this out, rcrsn51.
