beiing my tumbleweed on my TUXEDO InfinityBook Pro 15 v4, ssd disk=2Tb, /home EXT3 partition=58Gb, processor= Intel Core i7-8565U, RAM=32Gb, graphics card Model: ;Intel UHD Graphics 620 (Whiskey Lake) broken I had to use the emergency leap 15.1 system on another partition, bu I have a problem, fully updated leap 15.1, using networkmanager, it doesn’t shows wireless present networks, nothing, and there are at least three, only wired, that luckily works:), how can I get wireless networks shown by networkmanager??

Please show (in Leap):

/sbin/lspci -nnk | grep -iA3 net

Is your wifi switch set to off. Many Laptops have a switch that some drivers ignore but the iwlwifi do what the switch says to do.
Some BIOS allow you to disable the Switch, see if the BIOS has a switch option - turn it off.

…it seems not, the disable/enable wifi bluetooth switch in my BIOS is enabled

Install rfkill and post:

/usr/sbin/rfkill list all
/sbin/modprobe -c | grep -i "8086.*2526"

Hi, manythanks, …today morning at 9:30 three of the four (seen with a windows pc next to the mine) wifi network was shown in available connections, two of they was already configured with password and username in “rightclick on networks icon>configure network connections…” I connected to one of they and navigate fairly, now, I was answering to you only the active connection is shown no available connections is present (seen with windows pc there was four)
rfkill was already installed and this is the output:

pla@pla4ST:~> /usr/sbin/rfkill list all

        Hard blocked: no

Does it work now?

now yes, I changed network, now I’m at home, networkmanager shows many wifi networks and connection works, but when I answered you I was at work with other wifi networks didn’t work, I’ll come back at work monday and I will check
