Broadcom wifi using 4311 chip on Dell with Tumbleweed

just installed Tumbleweed on Dell Inspiron and cannot get wifi working after reading numerous discussions about the older chipsets. the script install_bcm43xx_firmware fails with an error saying (stdin) is not a bzip2 file. the scripts is fetching a file from Index of /b43-firmware. I guess my next step is execute each step in the script manually in a terminal

Or try broadcom-wl from Packman.

don’t know Tumbleweed well enough to get packages. Packman is confusing, I can see the packages for Tumbleweed but not sure how to download/install

Connect to network with LAN and add the Packman Repo:
https://en.opensuse.org/Additional_package_repositories

After that, install broadcom-wl, broadcom-wl-kmp-default and broadcom-wl-ueficert.

Restart.

installed those packages. wireless still not working. lspci says it uses b43-pci-bridge but modprobe says not found. I’m clearly not the first who has gone through this struggle as I read the various postings

Is secure-boot enabled?
If yes, have you added the key?

no idea what secure boot is

Post:
mokutil --sb-state

mokutil is not installed. this is an old laptop from 2003 which was before Dell started using UEFI so doubt secure boot is involved. I looked at BIOS settings and dont see anything enabled regarding secure boot

So post:
zypper se -si broadcom

since the script for firmware install is failing, it seems from reading many posts that its the key issue. the script fails because file is not recognized as correct type, maybe corrupt. another user posted report about this script but unknown who is the maintainer of it

Post:

/sbin/lspci -nnk | grep -iA3 net

Please use Code-Tags for the ouzput:
Code-Tags

TW 32-bit is not supported.
ILL WiFi chip doesn’t support WPA2 or newer, also lacks 802.11n or newer.
Replace that laptop with newer one.

TW 32 bit is supported but the firmware problem exist because the install script fails. I did a successful install of Bodhi linux and have the wifi up and running since the apt-get Install_b43_firmware is successful after removing the broadcom-wl files

So delete all broadcom-wl packages and execute the b43 Installation script and post all from it here in Code-Tags.
