My internal Wifi  failed to see my Router soon after I started with Linux  so I installed a USB dongle I had

The dongle works OK for a while and then I loose my Internet but not the wifi  connection . If I disconnect/connect wifi it works ok for a while . There does not appear to be a pattern to when it fails.

It is a Realtek RTL8188CUS 802.11n using  WLAN Adaptor driver : rtl8192cu which is also installed in WinXP

I am hoping someone can give me a solution that I can understand preferably using GUI as other than trying to sort the problems I have had I have no need to learn CLI . I just want to do everyday tasks on my computer.

I have searched the Internet and there could be an issue with the Linux Drivers rtl 8192cu for the Realtek Adapter . Unfortunately for me the solutions mostly involve using  Command Line . I have tried some but get confused when they are not recognized.
With the many flavors of Linux I am not sure if they all should work in  Lite 2 . Also having  only a very limited knowledge of CLI its difficult to know if the commands given require me to be in the correct command structure before they will work .
Also the outputs are in such an abbreviated  form that needs converted to normal language to know what they mean !!!!

Your Forum profile says you use 1.0.8. Can you please confirm for us what version of Linux Lite you are using? Also, just for the record there won't be a GUI way to install this wifi adapter, if it is not playing ball, the command line is the way to get it going properly.

Could you open up the terminal and type in:

Code:

lsusb lspci -nn | grep Network lsmod

These are three different commands. Hit the enter key after typing in each line.
Then post the output by copying then pasting here.
Put the word code before the output, wrapped in [ ], then at the end put the same thing but with a / between the [ and c.
This is called code wrappers.

Thanks
I have updated my Profile to Lite2 and run the commands -I hope this helps

Thanks for the instructions . I hope I understood them and got it right . An example would have helped me understand

Question.
Have you already typed in a terminal:

Code:

sudo su apt-get update && apt-get dist-upgrade

?
If not, plug computer into the back of the router and do this first. After it's done reboot and see if it will connect properly.

EDIT: You did good!
Could you post the Manufacturer, model number, and year of computer?

[Colin23erk]

Hi Thanks for that
I assume you meant me to connect using an Ethernet cable  so I could connect to the Internet to download the update .
Am I correct in thinking that the commands are the same as using the upgrade from the Menu .
If so I had done it again yesterday .

Just to say that the WiFi Dongle does connect through the Wifi Router and I can use the internet OK for a while . Then later when I try to go to a different page I get a message saying I am unable to connect .
Network Manager still says I am connected to my WiFi . If I disconnect and reconnect using Network Manager everything works normally immediately until it fails yet again .

I have a different computer that uses the same Router . It has no problems using the Router as did this one before I needed to use the dongle .

Let me do a little bit more research.
I think I might have found a solution/path to a solution.
I'm like a blood hound following a scent.
Please post manufacturer, model number, and year of computer.

[AndyOpie150]

The doggle is a TP-LINK 150bps wireless N usb adapter, right?
Model number TL-WN72?N. Could you fill in the question mark please.

EDIT: Just to be on the safe side, could you type in a terminal;

Code:

sudo su apt-get install firmware-realtek

[Colin23erk]

The  Netbook which I had the problem first is an Advent 4211 bought August  2008 is in pieces to repair a broken hinge

This is the output from my Samsung NC110 Netbook which experienced a failure with the USB WiFi dongle this session . The dongle consists of  usb connector with a 1/4 inch of black plastic has no name on it . All that is written on it is 802.11n

Code:

colin@colin-NC110:~$ sudo su [sudo] password for colin: root@colin-NC110:/home/colin# apt-get install firmware-realtek Reading package lists... Done Building dependency tree      Reading state information... Done E: Unable to locate package firmware-realtek root@colin-NC110:/home/colin#

Hope it helps

[AndyOpie150]

I'm back. Got to dig some more.

EDIT: Might have to compile the module from the driver found here: http://www.realtek.com/downloads/downloa...=true#2292

Will read up on it more so I can walk you thru it if absolutely necessary (really don't think it is though). Will look for more alternatives.
I'm really starting to think by the output of the lsmod command that a firmware update is needed. Will look into this as well.
