Netgear USB N150 wireless adapter keeps asking for password ubuntu 12.04

[katsumodo]

Sorry for the delay in responses, I was out of town for the weekend. But I'm back and ready to tackle this wireless network debacle once again!



So here's what happened when I tried what you replied with:

sudo modprobe -r rtl8192cu

results:

no errors or results back in terminal, but the small black network connection indicator window pops up in the top right hand corner of the screen and displays “Wireless Network: Disconnected.” Also at this point wireless networks do not show in System Settings > Network. Only ethernet.

lsmod | grep -e rtl -e 80211

results:

no results were given in terminal, so I guess nothing to remove?


Load the new driver:

sudo modprobe 8192cu

results:

no errors in terminal


Check:

dmesg | grep 8192

results:

[    0.829439] agpgart-intel 0000:00:00.0: detected 8192K stolen memory

After doing the above steps it unfortunately looks like we still have the same problem. Wireless doesn't pick up on it's own and wireless networks do not appear in System Settings > Network. Only "Wired" and "Network Proxy."

[ 728.985365] usbcore: registered new interface driver rtl8192cu

This may be an issue. It looks like the same in-kernel driver was reloaded. Let's verify. Please repeat all of the commands above and check:

lsmod | grep 8192

Is it rtl8192cu that's loaded or the driver you compiled, 8192cu? If it is 8192cu, the compiled version, we know it isn't helping us at all and we may as well uninstall it:

cd Desktop/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622/
sudo make uninstall

The next thing we might try is the Ubuntu version of the compat-wireless driver:

sudo apt-get install linux-backports-modules-cw-3.3-precise-generic-pae

Reboot and let us know if there is any improvement.

how come it won't uninstall? I've seen this before but haven't figured out why it appears.

Thanks again for all the help Chili!

Let's see what our possibilities are:

ls ~/Desktop/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622

I know there is an install.sh in there, but is there an uninstall script or ...what? If there is a README, please attach it to your reply if you can't see any uninstall instructions.

[katsumodo]

I couldn't find any uninstall scripts in this folder. I've attached all the documentation I could find. I went through all the documentation and couldn't find anything that related to uninstalling it. You'll probably be able to find something though if it's not as obvious.

[chili555]

I couldn't find any uninstall scripts in this folder.

What all is in the folder?

ls ~/Desktop/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622

Is there a tarball in there that the install.sh extracts that itself contains the Makefile; and therefor the 'make uninstall?'

[katsumodo]

The path to the folder that was on my desktop i think is the wrong one and an earlier one that I was playing around with. The path to the one I believe is the original is listed below.

jon@jon-desktop:~/Desktop/Jon/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622$ ls
android_reference_codes install.sh
android_reference_codes_ICS_nl80211 readme.txt
document ReleaseNotes.pdf
driver WiFi_Direct_User_Interface
hardware_wps_pbc wireless_tools
install wpa_supplicant_hostapd

How about:

cd driver && ls

[katsumodo]

jon@jon-desktop:~/Desktop/Jon/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622$ cd driver && ls
rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622
rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622.tar. gz

[chili555]

jon@jon-desktop:~/Desktop/Jon/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622$ cd driver && ls
rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622
rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622.tar. gz

And there is the file the install script extracted. Now please do:

cd rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622
sudo make install

Then install the backports package and let's cross our fingers.
