Networks panel - available Wi-Fi connections etc. [SOLVED]

Postby FuzzyJ » 22 Mar 2019 02:13

Because of existing undependable power supplies I frequently need an option to access my desktop computer to a Wi-Fi connection or connect with a (plugin & play) USB aircard (dongle) to mobile broadband.

The Networks panel only shows Active Wired connection but no available Wi-Fi connections.

The radio button for Wireless power saving is activated and both Wi-Fi and Mobile broadband are set to "Turn on".

How can the system configured to show nearby-region available network connections in the Networks panel?

your wifi card is either installed incorrectly or the system couldn't find the approriate driver for it. do you use broadcomm or other propietary wifi card?

Thanks for responding.

My last operating system installed to this desktop computer was Netrunner 19.01. Prior to Netrunner I had Mint KDE and and then Neon installed. All three systems displayed available Wi-Fi connections in the Networks dialog panel and also was able using my USB broadband aircard.

After downloading the SOLYDK_9_64BIT ISO I burned the image to a USB stick and proceeded with the installation (no dual boot setup on this system). I verified the download (using GPG & SHA) as recommended.

The best to my knowledge, the Wi-Fi card was never re-installed and don't know if the SolydK installation somehow affected the ability to show the available Wi-Fi connections.

The red Airplane mode icon with (disabled) radio button is showing in the Networks dialog panel though.

If the Wi-Fi display issue could be resolved ie. finding the appropriate driver or whatever, than I could use my broadband aircard (dongle) to connect to the Internet also; It works in other operating systems without installing any additional software - I think it's called a PnP device.

As I put much effort in tweaking the operating system to my liking and everything else is working very well, I'd rather would avoid from re-installing it!

the broadband dongle could be configured using nm-applet. just click on the network icon, edit connection, add new connection, mobile broadband connection. as for the wifi stuff, we need to know what the type of your wifi card. please run "lspci" and tell us the result.

Isn't the above info icluded in my OP 22 Mar 2019 02:13 ?

What is the difference between terminal outputs lspci and inxi -FNzxx ?

lspci check all peripherals regardless the driver situation. it also gives more detailed information. OTOH inxi detect working stuff so sometimes some item missing from the list. anyway, your wifi card is missing. there's only one network card which is a LAN card

the hardware connection could be loose or the wifi card is dead. the other probability is that solydxk doesn't work with your wifi card. though, based on your description solydxk should work with your wifi card. if you have another linux on livecd format, you can try to boot that livecd and see whether if your wifi card is working or not.

My thanks for explanatory responses.

Sounds like code: 'lspci' would be a worthy inclusion to the directive "Questions about networking."

I already tried Netrunner, PC LinuxOS and Q4OS; The Wi-Fi card is working as expected.

Since your analysis also indicates a probable glitch in SolydK I am going to mark this post as [SOLVED].

After finishing this thread and responded to couple of other esteemed posters here I am going to re-download/check/install the operating system ensuring Wi-Fi is showing in the live USB.

Thanks again for helpful response!
