Install without the intel wireless wifi firmware; instead use ethernet RJ45 connection for install. Invoke Synaptic

Hello,

Whenever I use:

dpkg-deb --extract firmware-iwlwifi_0.43_all.deb .


It says, extract needs a target directory. perhapbs use --install?

Please help! Trying to get the intel wifi drivers to work

The only reason I can think of, would be that you omitted the "." argument (which stands for the current directory) at the end of the command.
Otherwise, I would suggest you replace the "." with an actual directory name; I can't remember if the directory has to exist before you run the command, though.

put firmware-iwlwifi_0.43_all.deb file into documents/firmware/iwlwifi_0.43_all.deb

inside your new folder, right click your new iwlwifi_0.43_all.deb file
choose/click archive manager

left click
extract in arch m

left cl
extract in
popUp window

lft c
show files

extract data.tar.xz
same method

cd data
cd lib
cd firmware
ls

here you have all the files
pick what you need for your media card used for install

Although this is OnE method, one answer to your specific question, still better to install without iwiwifi but use rj45 cable why?
faster
more secure

no rj45 socket on device?
thus use
gigabit plugable usb/ethernet/adapter

i'm officially out of school, and not in a degree program, however, i just got schooled this morning. this thread is awesome, and like everyone else who read it, i also wanted to thank all of the contributors

I just used this when installing Debian 10 on an external sd card on a Lenovo 120S Ideapad when its Windows 10 OS got problems. Even though the firmware deb package I downloaded had only a couple of the files reported as missing, it worked! Very helpful!

Although what is related to the question of providing the firmware files still stands, I just want to clarify that it is not possible to easily boot an OS from an sd card! I hadn't done my homework before attempting to do so!

Thanks, this helped me installing Debian 10 on a hp probook 4330 i3 with a wireless card Intel centrino, everything worked as you described.
Very useful, great job sharing.

Ps: installation was done from USB memory and firmware was on second usb memory storage, on root, don't put the firmware in a sub directory.

Thank you! This thread is still helping people in 2022 For others who have come across this thread and are using a USB stick as their installation media, I was able to get the wifi working just by copying the firmware-iwlwifi_20210315-3_all.deb directly into the FIRMWARE folder on the USB stick. The installer picked up on it with no problems. I did not need to extract it.

Thanks again for the detailed instructions in the OP

Good heavens! I could never have expected to still get replies to this post after such a long time.

Well, thanks for reporting this. I'll try this if I ever run into the issue again.

You are very welcome!
