Hi, folks.
I've got the very same trouble with another old machine I'm installing MX Linux 19.2 (running with kernel 5.4.0-3-amd64); it is meant to connect Internet through WiFi using that USB WiFi dongle, but it doesn't recognize it, probably due to driver missing... I have copied all the content from the CD which comes with the device (surprisingly, it supplies even the driver for Linux, but it comes as .tar.gz file ...!), and it is the same model rtl8188EUS.
Any tip about how to install the driver from that media?
Or, instead, would be easier to download it from GitHub and follow the procedures described herewith above?...

Thanks in advance!

Thanks for your attention, pal. I've followed all procedures described, and everything seemed to run smoothly. But unfortunately it didn't work; No wireless yet...
However, it is there! This the result of

Code: Select all

$ usb-devices

Indeed, the driver was installed, but, I couldn't make it to connect at my Wifi... What am I doing wrong?...

In fact, that was just according to the model name (nothing to lose) but the best is the QSI or at least

Code: Select all

inxi -Nxxx

or lsusb when the device is attached, so that we know the exact chip no and what's needed ...

Also, have you right-clicked on the Network icon on panel? (Check all 3 boxes: "Enable ..." )

Thanks again, pal!
I have this at the machine:

Code: Select all

pedro_lucas@bento:~
$ inxi -Nxxx
Network:   Device-1: NVIDIA MCP61 Ethernet vendor: Micro-Star MSI type: network bridge 
           driver: forcedeth v: kernel port: ee00 bus ID: 00:07.0 chip ID: 10de:03ef 
           Device-2: Realtek type: USB driver: rtl8188fu bus ID: 1-2:2 chip ID: 0bda:f179 
           serial: 00E0202FD755

And yes, I've right-clicked on the Network icon and set WiFi enabled... But no luck so far...

Thank you, too. Sadly this shows only wired (ethernet) card. What about lsusb ? (when the device is attached)

Edit: Saw you edited the post above and it's here:

Vendor=0bda ProdID=f179
Driver=rtl8188fu

So, it's exactly the same device with the correct driver. Then, there must be something else.

Oh: If you didn't:

Code: Select all

rfkill unblock all

If not again, enter Bios Settings and check if there's something "disabled" related to "network" ... (Also check if there's a tiny wireless button to switch off/on or the Fn Keys)

The command "rfkill" didn't show any effect... This machine (I'm typing right now on it, but using Ethernet...) is a old desktop...

Code: Select all

$ inxi

... without built-in Wifi! I'm trying to make it usable again using MX Linux, for a 8 years old nephew...
Well, here I go reboot the machine, take a look at BIOS trying to find out what is missing... I'll report what I eventually find...

That's normal. It gives no output, but silently unblocks if there's something "soft-blocked". It should be fine after reboot :)

Ok, I've plugged the wire to my own Desktop, so I can work and do handle other stuffs; the older desktop (SEMPRON) keeps not connecting through Wifi; however, and quite oddly, I've found out the dongle is working! It finds my Wifi net (and others around), but it fails to connect!! I've checked the usual details about SSID, band (2,4 gHz), security (WPA, WPA2), password... and nothing! The 'connecting' icon just goes round and round, and fails to connect. It fails even with the open Wifi net in the neighborhood...

Just to put a few of "gasoline on the fire": I've found this site referring to rtl8188EU wireless adapters; They have being problematic to work properly in Linux, indeed...

So, the driver is loaded and the device's working.

I'd say this from the beginning: From Menu : Session and Startup => Autostart Apps: uncheck Bluetooth (Blueman) (so that it won't conflict with the wi-fi) https://docs.xfce.org/_media/xfce/xfce4 ... ostart.png

P.S. The names are similar but that one is another model with a different chip number. We also solved that several times in the forum :)

You can also:

Code: Select all

echo "blacklist rtl8xxxu" | sudo tee -a /etc/modprobe.d/rtl8xxxu.conf

Reboot.
