[SOLVED] Fedora25 Wireless LAN with Realtek chipset

JJJCR · 06-27-2017, 05:49 PM

Hello guys, does anyone has a success connecting Fedora to Wifi using a USB dongle with realtek chipset?

Thanks.

ferrari · 06-27-2017, 05:52 PM

Do you have a particular device in mind? I previously used a Realtek USB device supported by the r8188eu driver which worked as expected.

JJJCR · 06-27-2017, 06:42 PM

It's a TP-Link USB dongle, it's able to see the Wireless but unable to connect even though the password is correct.

I think it's a 4 year old USB dongle, I turned off my desktop unable to see the details.

ferrari · 06-27-2017, 07:32 PM

How are you trying to connect? Any logs (error messages)?

JJJCR · 06-27-2017, 09:32 PM

I didn't check the logs yet, I'm trying to connect via the GUI desktop. At one point it says connected but just a few seconds it goes away and if I tried to connect it just says connecting and keep asking for the password.

Hi...

If you would, if possible, please connect the system to the internet using an ethernet cable and then open a terminal and run the following commands...

Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

Then navigate to the location of the text file the script created and post the contents (or a link to them) in your next reply. If you need to, you can save the text file to a thumb drive and then access it using Windows.

Regards...

any ideas how to make it work?

Thanks.

JJJCR · 07-01-2017, 06:26 AM

I can't make the Wireless work in Fedora, I Installed Elementary OS and it works fine.

Hi...

I'm glad you got it working with a distribution, if not Fedora. If you consider this resolved, please mark this thread as "SOLVED" by clicking on "Thread Tools" directly above your initial post. Thanks!

Regards...

JJJCR · 07-02-2017, 10:31 PM

Thanks Ardvark, it's working with ElementaryOS. The WiFi just got disconnected sometimes.

But it's working fine, I was able to update the OS already.

You're welcome, glad to hear everything is working correctly now.
