apologies for not posting with original post!

Stuff already done:
1. the file iwlwifi-7260-17.ucode is in the /lib/firmware dir
2. rfkill list all shows Wireless lan : Soft and Hard blocked = Yes
3. rfkill unblock all does nothing
4. hardware: the wireless and bluetooth are "hardware" enabled via keyboard. Bluetooth shows active in panel
5. Wireless shows as option in the panel
6. navigating to settings in network, shows wireless slide button in "Off". Slide it "ON" has no effect
7. lsmod |grep iwl outputs iwlmvm, mac80211, iwlwifi, cfg80211

any help/advice will be greatly appreciated.

thx -tC

yep if you didn't download an iso with "none free" in the name you are missing the needed wifi ingredients
i used this iso to install: ,followed by apt update to make install current. Next, i edited apt source list to include non-free to get and install iwlwifi; iwlwifi is available only in non-free. All this followed by the troubleshooting per prior msg. Let me know if i still missed some thing. Thanks!

You need to check the sources.list for the non-free Debian Repositories - if you are using the Gnome desktop
Code:
sudo gedit /etc/apt/sources.list
If you are using a different desktop then replace gedit with your text editor that you are using. - now look for the following

deb http://deb.debian.org/debian buster main contrib non-free
#deb-src http://deb.debian.org/debian buster main contrib non-free

deb http://deb.debian.org/debian-security/ buster/updates main contrib non-free
#deb-src http://deb.debian.org/debian-security/ buster/updates main contrib non-free

deb http://deb.debian.org/debian buster-updates main contrib non-free
#deb-src http://deb.debian.org/debian buster-updates main contrib non-free

If they are not there then add them and save the sources.list file

Then run
Code:
sudo apt update
Code:
sudo apt install firmware-iwlwifi
now reboot

i am using cinnamon desktop. Would the above steps change?

did you do everything according to debian wiki. what does lsmod show? rfkill still showing hardblock?
If so you'll have to clear that first. Also if you have secure boot enabled you'll have to turn that off.
