wl is not in the wary kernel.


Don't know if it helps - but wl is available for Wary5.5 at:

wl works fine for all latest Puppies and latest kernels up to and including 3.10....for me

@mikeb,
I've tried a few more things with this, and I'm none the wiser. ssb is not blacklisted. I have removed from the old savefile everything that I thought related to networking, but I still get
Code:
failed to raise interface wlan0
failed command was : ifconfig wlan0 up
Error returned was ifconfig: SIOCSIFFLAGS:  No such file or directory

@peebee
Thanks. I found your awesome collection of wl pets and used several while I was fooling around with different kernels. My wireless connects with b43 in later kernels, but apparently something in the original 431 savefile is interfering, whether b43 or wl.

Ok, back to making tamales Razz

Hi Wognath

That error usually means firmware can't be found - and the firmware loading mechanism did change between Puppy editions and kernels - if you look in dmesg there may be missing firmware error messages?

You will need to make sure that the firmware is present and is located in the correct place.

Cheers

peebee, you hit the nail on the head. dmesg output includes
Code:
b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
In Wary, this file is in /lib/modules/all-firmware/b43/lib/firmware/b43. Creating a symlink to that folder in /lib/firmware solves the problem and allows wireless to connect! I still don't understand what it is about the savefile that causes puppy to look in the wrong place...

Thanks to both of you for the help.

"But as the poster has pointed out, there are major differences between puppy series 3 and 4 so will be very surprised if the kernel switch will work in this instance. Why don't you try switching puppy 412 kernel with something later like a Wary Puppy?"
At home, the process fails with puppies series 3 and 4
I use SFS load on the fly , and load the SFS of the old Puppy, all the applications become available inside the installed recent Puppy.
Is that forbidden ?
What does 'underdog' mean in Boot options (PF3) ? is it similar as load on the fly ?

I finally downloaded James C's .iso (link on the previous page) and burnt it to CD. It seems to work well - I haven't spent a lot of time on it though - it is very cold here in the control room!
