Wifi problems after attempted configuration of Netgear g54/n150 USB adapter
Hello forum,
I recently tried to install drivers for the Netgear g54/n150 usb adapter, and not only did it fail but I seem to have removed/corrupted some general wireless interface configuration settings. As of now, KDE does not show any wireless capabilities (ethernet only). help!
Re: Wifi problems after attempted configuration of Netgear g54/n150 USB adapter
Please open a terminal and run and post:
Code:
lsusb
sudo modprobe rtl8192cu
Why did you decide to install this from compat-wireless since it is already installed by default? What didn't work as expected?

lsusb shows device is detected:

modprobe... :

I tried to reinstall the drivers because NetworkManager showed the device but failed to actually connect to any wifi network. I thought that there might be some driver issue, and saw other forums that suggested trying compat.

Interestingly enough I just solved this issue from advice on another thread.

Anyone, I went to this link:
http://www.realtek.com.tw/downloads/...oads=true#2772
Grabbed the 8192cu linux driver zip, unzipped it, and just ran
Code:
chmod +x install.sh
sudo ./install.sh
from the directory that was created when I unzipped it, and voila! I have a working usb wireless nic.
Ironic, too, considering I spent about 3 hours trying to get the compat stuff to work. :-)
Re: Wifi problems after attempted configuration of Netgear g54/n150 USB adapter
rtl8192cu is certainly correct for your device. You'll need to uninstall compat first to get your wireless system going correctly:
Code:
cd Downloads/compat_directory <--wherever you extracted the files
sudo su
make uninstall
exit
Now can you modprobe the old in-kernel rtl8192cu correctly?
Code:
sudo modprobe rtl8192cu
Are there any clues as to why it doesn't connect here?
Code:
sudo cat /var/log/syslog | grep -e etwork -e 819 | tail -n20
Re: Wifi problems after attempted configuration of Netgear g54/n150 USB adapter
uninstalled compat, then ran:
Code:
zev@zev-Lenovo-IdeaPad-Y530:~$ sudo modprobe rtl8192cu

Can you temporarily get a wired ethernet connection and do:
Code:
sudo apt-get install --reinstall linux-image-`uname -r`
Those tickmarks are on the left side of my US keyboard on the same key with ~.
Reboot and try again:
Code:
sudo modprobe rtl8192cu
Re: Wifi problems after attempted configuration of Netgear g54/n150 USB adapter
Wifi works now!
modprobe rtl8192cu returns nothing.
interestingly, the device now only manages to connect to a network when i unplug and replug it. If i connect/disconnect using network manager it fails. If this doesn't suggest some worrisome underlying problem, I can live with it, and let you get back to being one of the most helpful linux forum members I've ever seen!
Thanks

Meaning what? It tries and asks for your WPA2 password and times out...or...what?
Thanks for your kind comments. I appreciate it.

Hey thanks for the heads up on Realtek Linux drivers. After many hours fighting drivers trying to get my Gigabyte PCI card to work, this pointed me in the right direction. Just downloaded the script for my particular chipset (RTL8168B) followed the directions in their readme file and viola! Works great. Very much a newbie using Ubuntu 12.10.
