Title: Wifi unavailable
Post by: Username Ace on February 07, 2022, 10:58:02 AM
I need assistance with connecting my laptop to the internet via Wifi.

I recently installed Linux Lite on my computor from it's Ubuntu operating system. The wifi would connect properly without problem on it's previous operating, however,  I cannot connect to the internet via wifi unless it's through the Ethernet cable.

I ran this command "nmcli d" in the terminal which showed that through the Ethernet, I can access the internet, whilst the wifi status remains unavailable.

I also ran this command "lshw -c network" so that I can figure out the hardware adapter, so that I can update the driver. But, it does not show the hardware name for the wifi adapter.

Any assistance will help me out a lot.

Some laptops have a switch/setting on the laptop that disables WiFi - could be accidentally active
Have a look through the dmesg log for anything suspicious
Search the internet for your laptop model spec
If you tried Linux Lite from a live source (before installing) and the WiFi worked give that another try and determine hardware.
Try using a live source of your previous OS or any other bootable USB/CD and determining your adapter type from there.

Some BIOS/UEFI screens list the WiFi adapter.
Laptop manual/documentation may have some FCC compliance data regarding the adapter which may give a clue

Thank you for the responses.

I tried loading the previous OS using a disc. And the driver that I needed to update was "rlt8187." I followed this link to help me install the driver: "https://github.com/Dekadencee/rtl8187-Linux-Driver#readme (https://github.com/Dekadencee/rtl8187-Linux-Driver#readme)." However, I do not know why the wifi still does not connect.

Else,

This is also what followed after inputting these commands:
Code: [Select]
Hardware Lister (lshw) - B.02.17
usage: lshw [-format] [-options ...]
       lshw -version

   -version        print program version (B.02.17)

format can be
   -html           output hardware tree as HTML
   -xml            output hardware tree as XML
   -short          output hardware paths
   -businfo        output bus information

options can be
   -class CLASS    only show a certain class of hardware
   -C CLASS        same as '-class CLASS'
   -c CLASS        same as '-class CLASS'
   -disable TEST   disable a test (like pci, isapnp, cpuid, etc. )
   -enable TEST    enable a test (like pci, isapnp, cpuid, etc. )
   -quiet          don't display status
   -sanitize       sanitize output (remove sensitive information like serial numbers, etc.)
   -numeric        output numeric IDs (for PCI, USB, etc.)

Code: [Select]
Command: inxi -n

This does not show anything.

You got an odd result for lshw command.  Try again with

Code: [Select]
sudo lshw -C network
and post the results.

I added the code flags to make things a little more viewable...

As for the rtl8187...

There are many folks with this same in use..
https://www.linuxliteos.com/hardware_results.php?q=RTL8187+#search_results

The rfkill will show if the device is "blocked" as if switch is turned off - for internal Wi-Fi and Bluetooth typically.  This being a USB...


As for your system..
What OS version are you currently running.
Code: [Select]
uname -r
cat /etc/llver


What was the previous in that you mention "it worked"


You could try "Install Drivers" to see if there is anything specific, BUT
Not sure if the what you tried has any ill effects - as that GIT shows it 'worked' on Ubuntu 13

Sorry to inform that LL3.8 has reached the end of it support cycle.
As such, LL3.8 was also the last version to support 32bit architecture.

Please know that LL3.8 is no longer receiving any patches or updates - security or otherwise.
