Titel: Wifi rtl8192cu does not work, please help.
Beitrag von: poincare in 2014/05/15, 13:27:47

Hello,

I have installed siduction 2013-december Gnome and it installed OK.  I do not have ethernet but only wifi. My wifi is an 8192cu usb adapter. The rtl8192 or rtl8192cu module is being loaded as it shows up in modprobe. If I remove my usb device and reinstall it, the wifi adapter is still not recognized. This means there is no internet access.  I have searched the forum and I can't find any solution to how to get 8192cu to work.  Can anyone help please?

Thank you.

The driver for that is in the firmware-realtek package.  I have a Belkin n300 wifi adapter with that chip.  However, I must say that it has never worked anywhere near as well as a TP-Link USB wifi adapter.  The Belkin works within 6 or 8 meters of the antenna, but does not work upstairs in the house when it has to get the signal through the floor.

Do you have non-free enabled in your debian sources list?

deb http://http.debian.net/debian/ unstable main contrib non-free

Make sure non-free is on that line.  That's where firmware-realtek is found.

Hi,
the "non-free" entry please /etc/apt/sources.list.d/debian.list with the record (such as Going Easy has already said). Then install the firmware and test it again.


# apt-get update
# apt-get install firmware-realtek
