So my WIFI card currently just disappeared, and i i have no idea what to do and any solutions either make no sense, don't work or won't work.

Im using a dongle right now which works fine as soon as you plug it in, what about the built in wifi card??

It sometimes comes online but after restarting laptop, it disappears again leaving loop and LAN fine. I was able to use ifconfig and iwconfig and get a screenshot while the wifi card was working.

My card is a : RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller

iwconfig:

there is lo, wlp2s0 and eno3s0 with elp2s0 being my card and when its not working then eno3s0 is not there and instead enp2s0.

since im using a dongle right now, it says wlx7cdd905657fd.

ifconfig : what stands out to me is 'UP BROADCAST RUNNING MULTICAST'

just exactly what is happening to my wifi card, sometimes its one and sometimes its gone.

Ive tried installing some drivers, but i don't know what im doing, im still new to linux.


WIFI CARD: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller

laptop : Toshibah satellite pro

specs: Intel® Core™ i3-5005U Processor

4GB Ram

as for hard drive, im using an 128gb ssd for OS and 1tb hdd for all my stuff. I did this by replacing the hdd which was windows 10 and a slow piece of junk to an ssd with zorin os installed, then for the hdd 1TB i just got a caddy case adapter thingy where the cd player/writer goes, so i can't my cd player anymore unless i get an usb adapter and a ncie case for it, but lucky i came across a usb external cd/dvd player so im fine with that bit unless i forget to pack it when i need it.

OS: ZORIN OS Lite

using zorin os 15 core installation drive, just fails and wokrs fine on my other computer but haven't installed it yet, as i need a backup of my home folder, but stuck there as i can't log in normally where i just return back to the log in screen and broke because of a gnome indicator plugin or extension. For now im gonna install zorin 15 again but along side my old install and hope i can copy the files when ive installed the new OS and after i got the files, re install properly even though using booting into a live zorin drive thingy and use terminal, well i don't know how to do that properly or understand it. the cp command doesn't work because i don't know how to copy a rooted folder to another external drive and to open a file manager as root command does't work.

SO CAN I GET A RESPONSE, I REALLY FRUSTRATED HERE SPENDING A FEW HOURS EACH DAY FOR A FEW DAYS NEVER SOLVING THAT ONE SINGLE PROBLEM or is it all an hardware issue cus its old or outdated.

Two things to try...

Clean the electrical terminals of your wifi card.

Unload, then reload, the firmware for your card.

Try in lspci for your wifi card (mine is listed as an Network controller). Search online for what module controls it. Then try 'lsmod |grep module. If the module's loading, that's a start. If it's not loading a module, follow that. Is the module there, etc.

If the module is loading - Next, iwconfig. If it shows there, the firmware is loading. Pursue if not.

Report back how those work out.

It looks like RTL8111 is actually not a WiFi adapter - its a Realtek Ethernet controller (for wired LAN). When the card is 'working' what does lspci show (it should be pretty obvious which is actually the WiFi controller)? How about iwconfig? Or do you know more specifics about your laptop's model so it can found that way?

If this is an embedded device, perhaps it is controlled by the system's firmware - is that set to 'Enabled' (if option exists) as opposed to 'Auto'? (I only ask this because you mention it sometimes is unavailable after a restart, so perhaps the firmware is making some insane choice with 'auto')

RTL8111/8168/8411 is a 1Gb ethernet card, commonly referred to as a nic. Wired internet only. If you google your laptop with the word specs after it you usually get the specifications. Mine, for instance has a Qualcomm Atheros. lspci reports What I set out for you was a way to distinguish whether you were having hardware, module, or firmware problems. Read my last post and do it when the wifi is awol. Feed back the results and we can draw conclusions.

Hi,

I would look at the logs to see if you
can find a trail.
